Oil cooler: new seals for an environmentally friendly engine!

On a 944 engine the oil cooler is IN the engine, cooled by the engine coolant. Lately I found out that the housing of this cooler was leaking, leaving a small puddle of oil wherever I parked. This is not only bad for the environment, I personally hate these things!

Thanks to Youtube, there are countless tutorials how to repair this. The new seals + some special sealant weren't that expensive, but it was quiet a job!
You have to drain the oil and the coolant and the housing is in a not too easy to reach area, directly under the exhaust manifold !
On the bright side, none of the screws gave me a hard time, they all could be broke loose without drama!
Upon disassembly I found some issues, this repair had been done before, but poorly executed:


The seal wasn't placed correctly.
Also, there were 3 shims under this seal - which -at this time- I thought was a failure... because usually, only 1 or 2 are being used


During assembly I measured the height from the sealing surface to the deck of the housing. The allowed dimension is 0,0 - 0,25 mm gap. I also had to install 3 shims in order to meet this spec.
This is the situation without any shims - a big gap:


After I cleaned all parts and their sealing surfaces...


... I used the Curil-T sealant which Porsche recommends here prior assembly of the seal itself:

During assembly a special tool is required to align the housing to the engine block in order to allow the oil pressure relief valve to work without issues!

Now everything is back together and appears to be oil tight - actually for the first time since I own the Porsche it is leak free (knock on wood!)  - at least: oil leak free...


Because, the next issue is already found: The right quarter windows seal is leaking:

 
The new seal is already ordered from Porsche and will be installed in the next few days...

Whistling noises

Lately I 've heard a whistling noise from the engine bay. The rubber grommet between the brake booster and the check valve leaked a bit of air. Upon closer inspection I also discovered another bodge of a previous owner. Apparently somebody broke off the little tube on the forward end of the valve and sort of glued the hose onto the valve housing:
The old check valve:

Missing tube and "glued-on" hose:

Old and new:

Rubber grommet: Spot the difference in diameter between new and old!

Final assembly: Another problem solved!
 
Final remark: After I ordered the valve from Porsche, I found out that the same part number (477 611 933 A) can be purchased from Volkswagen Classic Parts for half the price!
Porsche: 36,39 €
VW Classic : 18,96 €

freshly detailed

Even though the 944 gives me some headache currently, I spend time today to make it at least look good again. When I polished the old paint the first time, I didn't seal the surface afterwards, no wax, no sealant at all. So the dirt had a nice open surface to creap into it. It looked really terrible after a while, but today I washed, clayed, polished and waxed the paint, now it is all good again:

Honk if you're horny...

This bumper sticky gave me headaches when I first saw it in the early 80's. At that time no dictionary gave the information what horny meant...
Now I am a little wiser :-)
Unfortunately, this horn wasn't able to honk anymore:

Luckily, the Porsche has 2 horns. But the other horn had a loose connection, resulting in no noise at all when I hit the button. The other horn is reconnected now. Because sometimes you need to honk - for different reasons ;-)

Registration done!

After 1,5 years, the 944 is finally on back on the streets again!

There are still lots of things to do, but for now, I just want to use it on a daily basis!

Success!

Today the Porsche was inspected at the DEKRA to get back on the road. No advisories! In a few days I will register and use it!

Preparations for registration...

Tomorrow will be the first attempt to get the 944 back on the road. Mechanically, I am sure it will pass with no issues, but things like catalytic converter function - I am not so sure about...
While I prepared all paper work (which is a lot in Germany) I briefly checked the details of the Momo steering wheel technical data sheet. I always overlooked the little numbers which describe specific details for each vehicle. In paragraph 5 it says - only with excentric adapter!
Well, I did not install one, but luckily, company Sandtler, which is a leading expert in motorsport equipment in Germany is just around the corner. So, I hopped in my daily driver and picked one up:
I will awake the Porsche from hibernation today, hope it starts and prepare the last details for tommorows check - wish me luck!

DME Relay failure / hood lifter

Today I was haunted by the DME relay failure - a common problem on old Porsches. The car won't start! As usual - exactly when I have no time...
But there was no way around it. The Porsche has to leave the garage to make room for more important work. So, out with the relay and a "breadboard" test on the table:
A 12V power source ( in this case 11,1 V - but good enough for that job) a few jumper cables and an Ohmmeter. That is all it takes to check the status of the relay. The clipped-on cap is easy to remove, then there is a good description on clarks garage how to measure resistance. One circuit was dead. According to the experts, usually it helps to re-solder all joints.
A few blobs of solder later and the car started right away - result!
But as you can see, the contact pins have seen better days, so I ordered a new relay. It will rest in my glovebox - just in case...
The contact pins almost look burned - there is a lot of constant load on those during operation - which is basically as soon as the car starts or runs!

Just minutes before I also installed new hood lifters, as the old ones were a little tired, of course I chose OEM quality for the replacement parts:
A 5 minute job and only 23,80€ invested, but worth the effort. Now the hood will stay up any time.

Oldtimertreff Ruhr Termine 2017

Neue Informationen zum Oldtimertreff Ruhr für das Veranstaltungsjahr 2017,

Termine 2017 - leider anders als gewohnt


Jetzt steht es fest: letzte Woche sind die neuen Regelungen für Veranstaltungen auf der Zeche Ewald getroffen worden. Es gab Diskussionen wie viele Veranstaltungen der Standort und insbesondere das Umfeld (v)erträgt.
Durch Nachbarbeschwerden, die sich aber sicher nicht an uns oder andere schöne Formaten auf Zeche Ewald gerichtet haben, musste die Stadt Herten handeln. Es wird zunächst versucht die nächtliche Raser- und Tunerszene zu verdrängen Aber es muss auch zukünftig eine “Veranstaltungsrichtlinie” eingehalten werden, die Veranstaltungen begrenzt. Das trifft auch uns, aber wir werden 2017 min. 4 Treffen haben!
Fest stehen, die Termine 19. März, 16. April, 18. Juni und 17. September, der 15. Oktober wird vielleicht auch noch gehen.
Also – besser als nichts – und was dann 2018 wird, kann wieder ganz anders sein.
Also wir freuen uns auf die Treffen, auf den Baubeginn der MOTORWORLD und auf Sie!
Ihr OLDTIMERRTREFF RUHR-Team

Some additions for my tool collection

I have to admit, I am a tool addict. Usually I buy German quality tools and also some Snap On, Craftsman (not so much any more) and some other quality brands. Just lately, while browsing through one of my favorite forums I stumbled across a company from Korea which provides great tools for great prices. Even better, there is a German distributor for this brand. The company is called Toptul. The prices are ridiculous cheap and the quality is stunning:
I like the double ring wrenches with the 45° offset. And you can't have enough extensions! The neat little 1/4 inch ratchet has 60 teeth! The only thing I don't like is the fact that they offer different surfaces (mirror polished; satin chrome) and you cannot chose which one will be delivered...

A long overdue update...

Currently it is too cold in the garage, but I wanted to show some things I did recently to brighten up the tattered interior.
First I tidied up the trunk and carpet, then I added a luggage net to prevent the "junk in the trunk" from moving all over the place:



I also added a nice set of floor mats. On the left you might see a very bright light. I replaced the old 12V filament bulbs of the interior and dome lights with LED ones. This is a huge improvement in lumination!

Can't wait to get this thing back on the roads!

 Note to myself: Don't forget to replace the hatch seal!
