Front strut issues resolved, once and for all!

Today we finally found the issue with the front struts! After countless strip down and reassembly sessions of the front struts, we found the mistake - which I made during assembly! When you go back to the beginnings of this blog, you might find this picture - the root of all evil!
In an attempt to do only the best for my new shock absorber cartridges, I used an "old trick" and filled the strut with oil to cool the strut... BIG mistake!!!!
The trick was used in the olden days, when oil pressured shocks were used. The Bilstein inserts are gas filled cartridges. There is a valve in the bottom of the cartridge which "breathes", depending on the movements of the shock absorber. Now, what happened and how did I found out?
When I took the strut apart today, I told my buddy to be careful, cause the strut is oil filled. When we poured the oil, it was almost nothing left of the initial 100 ml I inserted, maybe 10 ml only?

Then I tried to compress the cartridge all the way to full droop. I was irritated by the fact that it only worked about half way, then was totally blocked...
Here is the reason why, the valve basically sucked in all the oil, which then acted like a hard stop. So, the strut actually bottomed out on every pot hole and gave a harsh impact to the body!
Then we inserted the cartridge upside down in a bench press and tried to gently push the oil out:
after a while it started to bleed, then we gradually added more pressure:
You can see the oil pour down alongside the piston rod! Slowly but surely, it all drained out - but: is this thing still in perfect order, after all that oil ran through it's gutts? I wasn't convinced, so a trip to Mittelmotor was required to buy another pair of inserts, this time B6 Sport - a hair stiffer than the standard B6.
Interestingly enough, on the left strut the oil was still in the strut - I don't know if this insert wasn't o.k. and for whatever reason the valve didn't work - or maybe it wasn't that much stressed, as most of the pot holes are on the right side of the street. Nevertheless, we exchanged both struts.
Now, finally everything works well. I hope it stays this way. Happy days!

Sealing a seal?!

When I purchased a new hatch seal, I was fully aware of the fact that it had to be installed using a sealant in the clamp-on channel which attaches to the body. This is also what the website of kyle, only makes very clear. I was a bit lazy and gave it a try without sealant. To no surprise water ingressed into the boot, due to the capillary effect of water creeping virtually everywhere.
So I bought a cartridge with an elastic sealer and applied it today:
This shall do the trick!
While I was in the garage with the heater working, I also applied a light tint to the back-up lights:


It is a self-adhesive foil which can be removed, when I want to backdate the Porsche again later!

A nerve wrecking job...

I managed to attach the Porsche script onto the back - which is a nerve wrecking job. I measured and adjusted the 2-piece sticker for almost 2 hours, before I finally attached it! A special thank you goes out to my friend Rui, which allowed me to use his hoist - otherwise this job is almost impossible to achieve!

First I marked the center of the vehicle and the center of the sticker, then I attached a few strips of tape in the center and below the tail lights to mark the perfect height  (these mark ups have to be in an area between the individual pieces of the sticker):

On the upper protective layer of the sticker I marked the upper and lower edge of the text, then I cut away some bits of the protective layer in those marked areas, so I was able to adjust it perfectly right:

Marking and lines are matching...

.. on both sides:

Then it was time to take a deep breath and finally attach it, this is the result:

I Also bought some 3M Scotchcal adhesive to black out the area between the tail lights:

and here is the direct comparison:

I like the contrast, it makes the rear look wider and less boring :-)

Currently I think about a black 3M gravel guard sticker on the rear fenders, similar to those:

Back from the body shop!

Yesterday I could finally pick up the 944 after the extensive body repair. Those guys did a great job:

The new rear panel, a new bumper and rubber strip mounted, perfect straight lines...

The PORSCHE decal and the 944 badge will be added soon. I think I will use some vinyl to black out the area between the rear lights - as it has been before the repair:

On the inside:

I already started re-assembly. To affix the carpet on the sides of the trunk, Porsche uses some plastic clips which wear out when you remove them. I found a neat little 2-piece clip which works perfect:

You can easily push the centerpiece in, so the legs of the clip spread out, when you pull the pin out again, the clip can be removed without any damage.

They come in a box of 6, for ~6€. the only thing I hate about them: They are originally from a French car... Everybody who knows me, knows that I am not really the biggest fan of French vehicles...

Amazing discoveries (of the unpleasant kind) and: Help is near!

As mentioned, the Porsche got rear ended, about a month ago. In the meantime the insurance issues are almost fully solved, so I started the dismantling. What I found was not so nice!
To make sure the Strosek bumper will fit properly, it was glass-fibered onto the metal and the paint was removed, so the bumper was laminated onto raw metal. Apparently the whole area wasn't 100% water proof, so, over the years water entered those areas and did a good job!

look at the butchery to make the bumper a good, flush fit!

Obviously, this panel has to be replaced! I contacted my local Porsche dealer just to learn this specific panel is NLA!(no longer available). I searched the internet and found a British company which advertised this panel (for crazy amounts of money) - but it was my only chance, So I ordered online and tranferred my hard earned money - The next day the company replied: Sorry this part is NLA, we will refund your money!

Now I was screwed - how to repair the body without the proper panel? Just by chance I browsed and - believe it or not, exactly this panel was in an auction, ending 3 days from there. I entered a bid in the last second and luckily (again) I was the only bidder and got it for a reasonable price.
Today it arrived and I have to say that I am well chuffed, it is dent free and was shipped in a lot of protective material - see for yourself:

lowering job, part 2; a new stainless exhaust and a crash!

2 weeks ago, I was able to finally lower the rear end, too, now the stance is just right!
I had several issues with the front struts, there were knocking noises which I fixed after several removal and assembly sessions.

Last weekend I installed the stainless Dansk exhaust. This is the old, tired exhaust (I know the heat shield needs some work, as well as the diff housing...)

and the shiny new Dansk exhaust:

Note the modified rear hangers to accomodate the rear bumper without exhaust cut-out

and I replaced the amber indicator lenses with clear ones:

I was well chuffed and all was good, until this morning, when I got rear ended on a red light:

rear apron badly reshaped:

Apparently it flexed back, as the flange on the trunk floor is also heavily deformed!
The damage is severe, luckily I got away with a little shock and some neck and headache! I hope all goes well with the insurance. The sad part is, that the vehicle was damage free for 31 years!

lowering job, part one

When I visited the Sommerfest of Mittelmotor recently, I bought a set of lowering springs with TÜV certificate which I installed yesterday. The ride is not more firm, still comfortable. This is the comparison between the og Porsche springs and the new, progressive wound springs:

The difference in height and especially the progressive style vs. equally wound og springs:

 This is the result, the rear will be lowered too in the new future...
