what did you do to your 944 today

Swore at it. A lot.

Looks like a piston ring might have gone, or a valve, or both. Taking the 996 to the Ring this week then June will be Marie Antoinette time for the Twbo - off with his head!
hi David

I've seen your posts and video on FB...it's a difficult one but try to do this in logical steps....first question is..was there any sign of this at all before the car was taken off the road for it's bodywork?..if the answer to this is 'NO' then the next question would be what's been changed since? I can't see a valve seal or ring suddenly giving up the ghost,possible but unlikely. I think someone mentioned a rebuilt turbo?...if so, perhaps the oil seal has failed, not fitted properly?..My first point of call would be a leak down test or at least a compression test, please forgive me if you've already done this and I've missed it. I wouldn't take anything apart until such a test has been done..

good luck

Pete

Pete's got a good point.

I haven't seen your posts - what are the symptoms?
smoking exhaust, IIRC David said a hint of blue, not sure if I could see any....crank pressurising with blow back through the oil filler (AOS)...there may be more , I haven't read all of the posts and couldn't find the thread just now....

 
Not sure if you can see these without joining the group...

Well I had a hydraulics day today.....

brake fluid change (motul RBF 660) and new clutch master & slave cylinder (+ replacement blue hose..)

It would have been straightforward had the unions on the master & slave wanted to come undone - they needed plenty of heat to shift them. Clutch bleeding wasn't too bad - took me 3 goes but seems fine now.

 
Fitted another re-con alternator yesterday after it became apparent the one from eBay wasn't as reconditioned as the seller thought............anyway had time to do the job myself this time which is always good. This allowed me to see that the "specialist" who fitted the other alternator seemed to think hammering off the undertrays was a better idea than unbolting them. My previously correctly attached aluminium tray was now only connected in 1 place and had a bolt missing in the middle connecting place and a broken tab on the other. So I spent an hour correcting this issue. Next I found out he only wanted to tighten some bolts on the airbox [&:] . And then the piece de resistance. Alternator shroud, previously connected properly with all 4 bolts, was now not even sitting in the right place with one lonely bolt half tightened stopping it from moving. Argh. We also had the rubber grommet rammed up the loom doing f all. Honestly what bloody chance do you have with people doing things on your pride and joy that just don't give a friar tuck? Anyway all sorted now, alternator all good and also nipped up my front wheel bearings a tad whilst car was up on axle stands. Ordered new plugs, cap and arm from CP4L. Bosch plugs and Beru cap and arm, £40 delivered and arrived today. That shall be a job for the weekend. Good news is I can now do an alternator, at the side of the road, on a turbo, in 2 and a half hours start to finish. I'm quite happy with that! Stuart
 
This is why I'll never use a so called professional to do any jobs on my car Stuart...I learnt the hard way and won't go down that road ever again....

Pete

 
Yes Pete 100% correct. I simply didn't have the time and took it to local place who races 2 x 914's and had a 996 and 997 in for work. Sadly the result was as detailed. So I used a half day holiday yesterday and spent a therapeutic afternoon in the sun doing some remedial work on the old girl!

glad you enjoyed your afternoon Stuart...I have to say that my experience with a well known Porsche specialist was far more costly. The list of mistakes, bad workmanship and I believe dodgy practice over the couple of years that I used them adds up to a lot....first experience was a 'pedal to the floor' clutch pedal....they picked the car up and told me the clutch had failed....today knowing much more about the car I would be looking at a fluid leak more than a failed clutch. I'll give them the benefit of doubt on this but when I got the car back they had broken a sensor for which they charged me full price but worse still they advised that the rear main seal was leaking....this after putting the car back together? who the hell operates like that? There are of course all the other failings, destroying my turbo by not drilling open the plastic elbow for the water to get through and cool the turbo when fitting a new water pump. At the same time, the car had gone in for new belts, rollers, all new front seals as it had an oil leak....car was delivered back to me at Pinewood studios as I was flat out on a film. Go to car at end of day to find not only an oil leak but also a coolant leak and steering fluid leak, they had clearly forced the items to one side to get at the engine. This cost me a new radiator and a repair on the steering pump hose. The damage was first checked by my son on his ramp at work over the weekend...I phoned the specialist from my son's garage as I knew they were open Saturday's and got the manager to pop down, the two premise's are within a mile of each other. He agreed to take the car back in on Monday to fix, my son popped in unannounced to see who was working on the car and how things were going. They had a young lad doing the work, this after all the problems was a joke and showed how much they really cared, my son asked the guy who was working on the car what he'd done so far and then checked the related bolts, some of which he could undo by hand?...that was the final straw and the car hasn't been near a so called specialist since. I might add that this specialist was often found in the pages of Post Post, one of the reasons why I went to them in the first place being a member at the time. The car was very new to me back then, I doubt any Porsche specialist or Porsche tech today knows more about the car than I do now, what i don't know I just let my son sort out....

Fitted new rear hatch struts this evening -cost me £30 the pair delivered from FA Parkes Sandbach.Amazing difference & no need for my ramin parting bead supplementary support any more[:)]

 
Hoping it’s a stuck ring - will try oil and freeing it off, compression on cylinder 4 is 10psi.

Won’t be able to look at it until next week anyway.

there is more than one ring, 10 PSI does not sound good at all, they would all need to be stuck for it to be that low

 
Fitted new plugs, cap and arm. Quite a difference in the car. Much perkier. Old plugs quite worn with gap elongated due to worn electrodes. Old ones all nice and clean a nice normal colour which is always good!

Priced up a rebuild and machine work to the block and some new pistons, etc.

Am expecting worst case scenario - especially after a conversation of the symptoms with Alex Eacock at EMC and some preliminary bore-scoping with my middle-aisle-of-Lidl-special Camera.

Was supposed to be travelling over to the Nürburgring last Thursday until this Tuesday in the 996 but managed to get myself admitted to hospital for 4 days instead after an investigative procedure showed I was at risk of a perforated bowel. Not my best laid plans to be sure - but am fine and now have another couple of days off to take my the end of the month, so will get the head off and find out what I’m dealing with.

Thinking of the positives, by the time I factor in what I havent spent in Germany and the money I’ll get back from the travel insurance, that’s my pistons paid for :)
