Just wondering how common engine oil leaks are for these cars. This is my second 928. My 9 year old '80 euro had a small leak and so does my 20 year old '84S. Also both cars had/have a "clacking" or ticking noise coming from the top of the engine... sticky valves?

The sound is the injeters
oil leaks (not good) but how BIG is your $$$$$.

 

Oil leaks are all at the bottom of the engine, no leaks at all visible from the engine compartment. Not sure if I want to fix them or live with them yet. Any easy way to clean out the injectors? When I bought the car they wern't making noise, maybe because it was hot and had been driven about an hour.

they wern't making noise?
I hope thay where.
To clean them use a cleaner in the gas (LM) is good.

 

Lot's of post's on injector ticking/clicking.
Lot's of stuff on the lifters clacking with potential cure or two.
Oil leaks?
What kind of oil are you using?
If you made a recent switch to Mobile One or similar synthetic some folks switched back to high grade Dino oil because of leaks and the leaks stopped after a while.

Oil leaks?? in a 20+ yr old Porsche??

Who doesnt have any??

 

Brian,
FWIW
My 82' Weissach has a weep back between the TC and Tranny but does not form a drop, no oil leaks at all from engine since I rehabed the oil sending unit and replaced the oil fill canister seals/gaskets. My son's 81' was supposed to have a cam tower -half moon- leak but I can't find it. No drops or seeps visible.

 

I had several oil leaks when I bought the car, thought they might be from the cam towers or some vicious place...but mechanic in Woodinville, WA did a T-belt job shortly after I bought it and fixed a small leak here and there, including front crank seal, oil pan tighten....and not a drop has leaked in over a year. I use Mobil 1. Can't believe it but there's never a drop on garage floor, even after hard running. I keep pulling the dipstick to make sure that it still has oil inside...it does..so I know that leakless is possible.

They can be made to "not leak" it just doesn't last very long, especially if you use synthetic oil. I do an oil pan tighten-up about once a year and that seems to keep the drips to a minimum. I am a big fan of the synthetic oil, so I am willing to put up with a few drips.

 

you think oil leak is bad, i can't find my oil dipstick O_O

?? Now i know it was here the other day

 

If it is covered with crap that is one thing, if it is gone, you have a major vacuum leak and the car will idle "high"......

 

Now, if I could only get the tranny-pan gasket to seal!!

 

Do you see it anywhere O_o?

 

yellow thing next to your "brace hanger-on"? Picture is hard to make out with the shadows.....I am also not intimately familar with OB engine bays.................How is your idle?

 

idle is normal at 1000 rpms + or - 100

nvm i think i found it, it' s the dipstick down by the fan belt, just a bit used to these newer cars with the big bright handle lol
