Is that an e36 M3 that's hanging all over mooty's arse?

2nd Video I see some puffs of oil smoke, welcome to the club Mooty. I have to believe that's a modifed M3 to be hanging with you like that. You need more power my friend, come to the dark side, join me and we will make your Cayman more powerful that you can possibly imagine...

I don't think that is oil smoke, itsmore likely amishift hitting the rev limiter....

Yeah, I've had people following me later tell me about puffs; it's always at the apex of a high G corner; no shifting involved. Plus, I don't think Mooty ever misses a shift

yes, that's fong's e36m3 lwt with 3.2L and other tasty bits. fong's quite a good driver and never fails to make me nervous and make mistakes. though i have made him do a few tank slappers in his gt3 when i was on his *** at button willow.


now if i can just lower my gearing.....

i have a button on the dash that deploys smoke to scare tailgaters. if it wasn't fong following me, i would have deployed my 'dump oil' button.


i dont think i missed a shift last friday at TH. most m96 based motors will puff smoke at high G loads and also at start up if you drove it hard.

tankslappers? haha, I though that was the natural instincts of the GT3, to twist and roll

I was thinking of crafting a letter to PCNA, Porsche AG and Wolfgang Porsche personally and letting them know about this problem and asking them if they can/will fix it. There must be some reason why oil is getting back up into the intake system of the motor and then getting ingested and spewed out the back. Mooty's oil puffs were much much smaller than my clouds of oil smoke when an ingestion event happened. At least by writing the letter if it comes down to Porsche claiming they never knew of the problem they won't be able to, they might also be nice and put an engineer on the problem and find a fix!

I heard today from a Porsche technician that there is some kind of recent bulletin and fix for 996 engines to do with oil smoke. I am not sure of all the details, but perhaps the Cayman has similar issues?

If there is I haven't seen it.... and its not listed with renntech or any other data servive I've seen.


I did have a simiar problem w/ my 996 TT though...the solution was to keep the oil level at about midway between the high and low mark on the level indicator. all the blowby stopped then... it all began when the dealer overfilled it one day....

i understand that if you reduce oil level a bit, less blow by.


but will that induce more likelihood of oil starvation? i dont really know.


when i tracked a e36m3, i was told to add 1/2 quart more oil than full.

Blow by on a horizontal engine under a high corner G load is probably due to the rings not-seated perfectly or micro-scratches in the liner...and under load that is parallel to the cylinder makes for an easy pass by for the oil.


Lowering the amount of oil in the car would do nothing to resolve this (and I'm of course just speculating on cause) issue. Long term, oil inside the cylinder as well as inside the exhaust will create (potentially) a slew of other issues that may or may not impact the car (cats, exhaust valve wear, cylinder liner wear, carbon build up and loss of performance, etc).


Just my take.
