Another year passed by with no drama!

Wow, I just checked the Blog and I can't believe it is already a full year without updates! But, actually, there wasn't much to report. The electrical opening for the trunklatch is inoperable since several months. Even another release motor couldn't fix that - but as long as the latch works with the key cylinder, that's fine for me. Then, in January I received a blurry picture from a speed trap. 25€ wasn't a big deal, it just bothered me, because I know exactly the location of the speed trap and I pass by it every single day - I must have been still asleep or something...

Then, finally some work was done to the Porsche. One of the pre-owners decided to mount an antenna for a cell phone, most probably in the early 90's, when it was "the thing" to have cell phone in the car. The antenna is long gone and left a gaping hole, which I covered with an Alpin white painted plug, but when I did that, when I initially "resurrected" the car, I already noticed some rust and bubbling paint in that area of the roof. It got worse in the last years, this is how it looked like a few weeks ago:

after removing the plug, the (w)hole picture revealed the horror:

Removing all of the paint and rot, was the next step:

a little "booger welding" later:

and finally, after some grinding, the patch was almost invisible:

I took my time with welding and grinding, trying to keep the area as cool as possible to avoid warping and distortion of the sheetmetal, which worked really good. A lick of zinc primer will protect the patch until the painter will take care of several issues:
  • the bonnet (or hood) needs a repaint
  • the roof and targa roof obviously need als a fresh lick of paint
  • I managed to "deform" the left front wing in my own driveway, this is most probably the biggest job
When the car is back from the paint booth, I will install the (fake) Fuchs wheels again. I protected the polished lips with a ceramic coating which shall avoid the burn-in of the brake dust... If it really works I don't know yet, but I will find out soon!

Some updates I made during the last 12 months...

Man, I have to catch up with some things I did in the past year, when the Blog was offline.
In January 2019 I changed the oil in the transaxle gearbox. I am not really sure, but most probably for the first time ever!
Coincidentally, it was exact at 269.000 km on the odometer

The biggest challenge were the drain plugs, they were rusted solid with the transaxle housing and took a lot of time and the use of numerous swear words before they were removed. The old oil was drained and a new drain plug was mounted, then the good stuff was filled in:

Finally another new plug, fresh from the VW dealer was mounted to finish the job:

 In August 2018 I repaired the Targa roof levers. The hinges were broken and the screws were rusty:

  I bought all required parts at the Porsche dealer - once more, much cheaper than advertised on ebay!

 The pins had to be pushed out, the levers themselves were fine, so they could be re-used on the new hinges, as well as the pins:

 All it takes is a good pair of pliers:

 Final result, working hinges with new, shiney screws:

fresh TÜV approval!

Wow, I can't believe that the Porsche is alread 2 years on the roads after the "partial restoration". But the TÜV sticker clearly stated that 2 years passed and a new inspection was required. As I had to update the paperwork anyways (legalizing the new wheels + tyres + front springs) I took care of this today. The result is another 2 years of road worthiness with no advise or issues:

Back on the Blog

Hi all, after almost 1 year, this is the relaunch of my Porsche 944 Blog. I will update the latest modifications I added to the 944 as well as some general updates of Porsche related stuff from time to time.

Here is already the most obvious mod: A set of Maxilite 7+8x16 wheels in the classic Fuchs design, with original center caps. The lips are fully polished instead of the standard "machined" surface. It looks really great, but it is a nightmare to keep them clean and shiny.

If you are visiting my Blog and you like what you see, drop me a comment, so I know I don't do this here just for myself.

Clutch slave cylinder, take 2...

After exactly 6 months, the clutch slave cylinder gave up again. On my way to work the pedal slipped down and didn't came back. Luckily, there was a little fluid left so I was able to shift the gears and ride the car to work. I called a friend who brought along some brake fluid to top up the tank for the way home. That worked o.k., so I managed to drive the Porsche back home without harm to the gearbox.
When I checked from below the vehicle, an already familiar failure was obvious:
Hydraulic fluid from the slave cylinder on the clutch fork...
This time, I wasn't interested in yet another cylinder repair, I ordered a new one. While I was at it I noticed that one of the contact points on the starter motor was broken, too. Somebody messed with it already, as there some traces of silicone and bodged repairs...
There is a lot of current running through these wires and I am not keen to see the car bursting into flames - This had to be fixed, now!
A new starter costs ~300 € - but the starter itself was working perfect, only the starter magnet was bad. Luckily I found a new replacement starter magnet for 30 €. The repair was a little tricky because someone has been here before:
Nothing a drill bit can't handle... The replacement fits perfect and also works like a champ.

 Also, the sticker says o.k. - so it must be good then, right?
All contact points are exactly the same, fitment is perfect, the only difference is a Philips screw instead of a 8 mm hex nut to attach the starter signal cable. Time will tell how good it works...

Now on to the clutch cylinder story: The repair set from Porsche was definitely o.k. - I guess it was me who messed up. The inner surface of the old cylinder just wasn't clean and smooth enough, before I re-assembled the service kit. It only took 6 month to wear out the new seal. This time I ordered a brand new cylinder:

Here it is, already assembled to the clutch bell housing.
Bleeding the system was a little tricky, but now the clutch and starter a fine again!

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!
