The lower (turbo) valve covers were slightly warped so planed them on some glass for a tighter seal. Would explain some oil loss but no drips on the floor (maybe one..two max) but often nothing. More seepage and a dirty block than an identifiable leak source.
All of the head studs still in place and retorqued slightly under spec for safety sake bless their little non breaking hearts.

What am I missing? Are you loosing/using more oil than usual?

Wachuko

I can imagine the stress of checking that

Thats one area i belive that if it aint broke dont fix it .. When i do my valve adjustnment i just make sure there are no broken studs .. and leave it at that .. i aint touching those things ..

Reiver

Yeah I know, so I torqued them to check going 8 lbs under spec...no more oil usage than normal, still a tad over 600 m per qt (620-650) but the warped covers allowed seepage.

I ain't touchin' ;'em either!!!!!!!!!! Damned right Ice (hehe).

Actually I asked Jack at Stuttgart SW how they check them and did that....he said if they are in basically ok to good condition they'll be fine. I wanted to know so took the chance....worked out thankfully.

600 miles/quart. Not really bad, yet. If the valve train is quiet, and it doesn't smoke during decel, leave it alone.

SC/Carrera head studs: Lookie, but NO torqie...

dshepp806

yeap,..no "torqie".......!

It smokes a tad during decel but only if you run it up to 4 or 5 grand 2nd/3rd and totally drop off the go pedal. The valves are not sloppy in the guides so I'm guessing some slightly worn oil scrapers....leak down is still good tho at 3-6 psi per pot.
Not bad for 227k.
Too late on no torqie tho...but survived. I'm not anxious for another try believe me.

I'm with the lookie, no torquie crowd here.

Lest you enjoy a butt-puckering, millimeter by millimeter fingertips only exercise.

I can think of better places to look for oil loss, such as the oil return tubes or topside usual suspects ("triangle of death"). If your clutch is slipping and you have oil from the bottom of the tranny bellhousing, then the crankshaft seal is another one. Only nasty is the #8 bearing seal. That one is no fun.

Reiver

Wasn't looking for it actually....valve adjustment and noted warped valve covers. Now not even one drip of oil after a 200 mile round trip today.

Let me see....he does what for a living?

And that, from a gentleman who made a living for many years working on these babies.

Reiver

Ed, normally I'd agree with you but Jack is one of the most honest guys I've ever dealt with in any business. He's the guy that checked my car for possible rebuild and told me to come back in 5 years for a recheck...also consider the guy a friend. I trust his Porsche knowledge. He's been doing nothing but Porsche's for over 35 years as a wrench and now as the owner.
There are a few guys on this site that know him and I'd guess they'd say the same.

Still reiver, you have ***** of steel. Wether you realize it or not
