Cool Oil Autumn

I love the fall - and this year has proven to be a great season for a number of reasons.  New house in the Halloween-loving Hudson Valley (Sleepy Hollow just erupts Halloween - it's like ground zero for the holiday!) coupled with beautiful autumn weather and it's hard not to get swept up in the whole vibe.  Living in NYC you tend to lose the seasons, of which there are two: it's either hot and completely miserable, or snowing with 50mph winds - the transitions are immediate and come without warning.  We are all really happy to be somewhere where you can notice earthly things like leaves falling, winds becoming gradually cooler, and the nights a little blacker.

It's also amazing driving weather.  Living in Croton has introduced me to roads I have only dreamed about.  Endless serpentine ribbons cutting through the woods with quaint bridges over protected watershed lakes, all perfectly manicured and completely empty... going to the Verizon store has never been this much fun.  Every turn reveals a new perfectly composed balance of nature and landscaped manipulation, and enjoying it all from the cockpit of the flat six is really just too good.  Such an indulgence - it's amazing.



Now that I have sufficiently expressed my gratitude, I think it's time to update the blog with my most ambitious project to date (save changing the oil... which is a whole thing in and of itself.  It's as simple as taking out the plug and draining it, but to do it correctly, you must maintain enough engine heat to keep the oil-cooler manifold open so all of it will drain.  This temp is just shy of 200 degrees.  Releasing the plug on 15 quarts of scalding hot oil is pretty dramatic...), which is the addition of a front fender mounted oil-cooling radiator and fan assembly provided by Elephant Racing.

I was hoping to avoid this job, as it involves breaking loose connections that haven't been touched for over 30 years.  I tried to have a porsche garage take it on, but they informed me it's too difficult working on these old cars, and didn't want to open up a can of whoop-ass worms should something give way - so I was left to my own devices, once again in the streets of Brooklyn.

The first step beyond assembling the cooler with the requisite stone guard, gasket, and fan assembly is removing the stock trombone cooler piping (literally just a loop of pipe, kinda resembles a trombone) and relocating the horns.  This was a fairly simple task as I purchased new, functioning Hella OEM horns which fit the space well and tucked up into the front of the fender-well nicely.

inside fender:  new horns, old backside of headlamp bucket.  what's all that bracket...?
This revealed my first snag: what to do with the mysterious bracket on the backside of the lamp globe.  This isn't supposed to be there, and serves only to confuse.  If I wasn't on the street, I could have left it alone, walked away and worked out some custom fabricated hanger piece that could incorporate this sturdy piece of metal into the install, but I can't just leave a jacked-up, oil-less 3-wheeled car on the street in Brooklyn, so I did what any other hack mechanic with a location constraint would do:  I beat it flat with a maul. 

From here the install went fairly smooth.  I got the lower bracket mounted up with stainless sheetmetal screws and sealed the whole area with clear silicone to prevent road detritus buildup and eventual rust.  I love silicone...  did the same with the upper bracket - if these areas collect grime and rust out, it won't be because of the silicone seal!


Working the short and very sturdy connector hoses was a pretty aggressive wrestling match, but I eventually worked them on.  I was able to work out the twist on the return line evident in the photo below, so don't worry - everything is straight in there now.

This was done at the end of July, and has proven to be VERY effective at keeping engine temps down, especially in stop and go traffic.  Where once I was climbing up to metal-shearing temps greater than 250º f, I am now under 180º - barely operating temps, and this without the fan hooked up yet.  I'll update this winter when I get that happening.

Striped or stripped?

I had this notion to add a set of home-made 1970's R-inspired vinyl racing stripes.


I bought ample material (a real nice, high quality 3M vinyl in off-white matte) and measured the areas I had in mind... but somehow got the cut wrong.  Measure twice, cut once, right?!?!  I was able to fabricate a set that will work on the car, but not in the area I intended, and certainly not the size.  I think I'll think on this a little more before committing.  Here's a gravity assisted mock up:



I know it's only vinyl and can easily be removed, I'm just not sure I want to waste the time to get them on there.  I can think of worse problems...

Back-seat drivers.

Wow.  October.  Hard to believe that I fixed the AC on this car back around Memorial Day, and haven't had an opportunity to post news of the fixer-upper-over-under-project since.  

It hasn't been an entirely uneventful season:  I did manage to complete all the small projects on my list - a few of which I will post here.  And we did enjoy the beautiful weather by trekking out to Robert Moses Beach on occasion, and I did manage to log 6000+ miles on the 911, and occasionally go to work.  Oh, yeah - and we moved.  Citizens of Brooklyn we are no longer!  So I have a good excuse for not updating the everyman porsche how-to blog.  

What's more, we moved to bucolic Northern Westchester along the river.  We now refer to Croton on Hudson as "home,"  and home it is:  thousands of livable square feet, a swimming pool, endless amazing-to-drive roads, and... wait for it.... a garage!  So my whole schtick around not having a proper work space, parking in the streets of NYC, and lugging my tools to and fro is now a moot point - a point that I am more than willing to let go.  

Got some good projects out of the way though under those conditions, and without further adieu, lets get into it.

Rear "seat" 3-point seat-belts:

Kids.  It's hard to live a selfish life once you start introducing new humans to the family, and I love my kids more than anything - more than life itself.  ...let me retract that:  I love my kids and my life with them - so let's all stay alive for a while, shall we?!  911's have a pretty bad (and undeniable) reputation for being hard to manage at the limit and therefore quite deadly...  something about cantilevering all the weighty parts of a 2400 lb car with 200+ horsepower behind the rear axle makes them predictably unpredictable.  Now, I'm not in the habit of taking turns at high speed with my 5 year old in tow, but I can appreciate the need to have him properly strapped in for expeditions of the grocery-getting and ice-cream-run variety.  The lap belts that come stock on the car are about as bad as having no seat-belts, hell - they might be worse... so time to upgrade to some PEP Parts aftermarket 3-point seat-belts.  Ya'know, for kids  (I am linking to the product that worked in my application after many hours of online research and reading through multiple forums on the matter.  Do your own research, and if you happen to read this and go strictly on my word, well - then it's on you if it doesn't work out)

In the 1982 SC, the rear parcel shelf and the perpendicular area behind the rear seat-back is a one piece combination of particle board/paper and some kind of compressed plastic hard core-foam, joined together somewhere around the right angle from seat-back to parcel shelf,  wrapped in vinyl (or leather, or...).  There are 4 screws holding it all in place, and a tab fitted to the particle board section behind the seats meets a metal loop on the car's firewall.  I didn't see anywhere online what this tab was all about, so here it is (once you know what you're working with, it all becomes very easy - or at least easier):


TAB.

So as you can see, once you remove the 4 screws, it's an up-and-out motion to remove the whole thing, speakers and all (which I upgraded to a pair of Alpine 517's - sound great and fit perfectly.  Matched to a blaupunkt under-seat 8" powered subwoofer, the system really pops, with just the right amount of, well, everything - and all in stock locations.  OK, to be fair, the sub-woofer is under the driver's seat, but is not visible from outside or within the car. You would never suspect how nice the system is by looks alone).

Being that I really didn't know precisely where these things should mount up on the steel firewall, I decided to take a chance and positioned the cut-outs for the belts first, then mark the position on the rear metal deck after.  It was the only way I could think of to get it in the right spot relative to each other.  So using a found photo of aftermarket belts installed, I used a sharpie and the plastic grommit that came with the kit to sketch a guideline for my razor.  Looked good to me - fairly straight and about in the right spot as I "a to b" compared the photo to my mark.  I cut out the vinyl and the thin layer of subcutaneous foam, and proceeded to rout out the shape from the odd plastic material with a cutter bit on the Dremel.  Oh - if you don't have a Dremel tool, stop reading right now and go buy one.  Countless hours saved over many projects by the hand of this tool.  Amazing.


rough, rough opening for seatbelt pass-through.
After a little clean up of the opening with the Dremel, I positioned the included plastic grommits.  Took a little maneuvering to get the inner layer of foam to stay put, but once it was all worked and screwed into position, the assembly was pretty clean.  For whatever reason, I opted to not take a pic from the visible side, so here's what it looked like from the important side, the side not visible from inside the car...


hole: ready!
Aha!  Found a pic...


From here, I proceeded to snap the shelf/seatback assembly back into position in the car. I then poked a sharpie pen through the hole and marked the metal deck where it lines up.  I removed the parcel shelf, positioned the belt reel behind my marks, outlined it with the sharpie, removed the reel and used my x-acto knife to cut away the sound deadening material from the metal deck/firewall.  Looked something exactly like this:



It would appear that I jumped the gun a bit, as there is already a hole in position in this pic.

After much positioning and checking the underside of the firewall I marked the hole position and used a stepped-drill-bit to cut the 7/16" hole (I think that's how big it was... use the bolt as a reference so you get it right). 

 Here it is on the driver side.  The base of the belt reel fitted perfectly against the metal ridge visible in the top left of the cut-out.  This is how I determined where to position the exact location of the reel (it was too perfect!) and proceeded to drill the hole for the retaining bolt.

The belt kit came with large, 3" diameter washers to offer a little resistance to just pulling through the firewall in an accident.  I also bought a separate set of dedicated bolts and washers and proceeded to double them up inside the engine bay.  I would have to say that between the two large washers, the aggressive lock rings, and the torqued double nut arrangement, I am confident that this isn't going anywhere.  Here's a slightly out of focus shot of threading the bolt and reel through my perfectly positioned hole (dumb luck came a bit into play here).  And apologies for the questionable photos... I pride myself on taking the time to do a nice job with the photography, but being outside in the high-noon July sun through the large greenhouse back window, I put photography on the back burner (no pun intended) and focused (also no pun intended) on just getting it done.





I failed to snap pictures of mounting up the rest of the belt hardware (see note above regarding "cabin heat" and "sweltering summer sun"), but suffice it to say, it all fit well and lined up.  I decided to trim about 30" from the seat-belt at the reel, and re-seated it with the reel's retaining pin as the amount of belt material was about 7 feet more than necessary. Being that the reel was over full, it would not recoil enough to keep the unused belt taught.

In the end, it proved to be a clean install, looks factory and is solid as all get-out.  Now I can pop my boy in the back for ice-cream runs without any pangs of guilt, because I know he's solidly in there and will be safe, sharp turns not withstanding.


all aboard! next stop: Blue Pig Ice Cream!






Inner Door Latch Handle UPGRADE


Also this summer, I upgraded the inner door latches.  This was a really easy job, and will probably take more time to type this then it did to do the job (I am a terrible typist.  I do generation X proud.)  I did snap a couple pics of the process though, and seeing the parts may prove to be very helpful for anyone else doing this upgrade.

The handles used to open the doors in these cars are flimsy.  It's quite literally the weakest part on the car, and are suspiciously out of step with the rest of the build quality - almost certainly developed on a Friday (Gott sei Dank, es ist Freitag!) 

The process is pretty simple, and I will just come right out and describe it here in a few easy steps:

  1. Remove Map pocket from door.  This provides easy access to existing handle hinge pin and spring clip.
  2. Remove metal "L" connector from plastic seat on back of handle.  Swing handle out to 90 degree angle from door, so you can get in there for step 3...
  3. Remove top spring clip.  See photo of removed clip below.  Laying a large, light colored sheet under work area is highly recommended as these things tend to fly. 
  4. Slide hinge pin out of the bottom of, um, the hinge.
  5. remove flimsy plastic handle
  6. remove white plastic seat from old handle, and snap it into new, high quality aluminum handle you just received from Rennline
  7. reverse steps to re-install.  Take your time inserting the clip as they are small and easily lost. Also, the hinge pin is a really tight fit into the new aluminum handle.  Next to impossible to get in there, so grab your small round file and ream out the handle a bit.
  8. open and close your door maniacally a few dozen times as you take in the solid, tactile feel that this has been missing for 35 years.
Easy Peasy.  Pictures?!?  Yes!:
Birthday stack: air filter, bosch fog lenses, hella horns, and new door openers!

Bits.

Clip, lower right.  This is what you are trying to work off that hinge pin...

Install Complete!!  Open and Shut!
