Hello to all...
Here's my dilemma: Bought a 911 - 930 turbo (1986) with a 964 turbo engine K27 / 11 TURBO (1991 engine) literally a week back for shipping to Australia (as we move there within the next 6 months). Please don't make me feel very sorry for not having the car thoroughly checked over (I am crying anyway!). Had the car shipped over to London by flatbed transporter. Decided to start her up today and give it a nice polish.... First 10 odd minutes no problem (added oil as was completly missing on dipstick), upon warming engine put down the pedal to rev up engine and guess what? all hell broke loose... oil pouring from the air intake filter like there was no tomorrow... all over the engine and on to now hot exhaust!! screams etc... wife runs into kitchen to get fire extinguisher -luckily did not ignite. I did notice bluey / hazy smoke from the exhaust before the main 'show'. Please,please advise as to what the possible faults might be so that I can get the spares etc and ship with car to OZ where I will work on the same in time. I have only got 2-3 weeks left before container shipping people take all to their werehouse for storage. Anyone with a workshop who could rectify in this time please get in touch if I can be helped given the short time. Any advise most welcome and sorry for the long post!
Live honest!!

Exactly how much oil did you add? Your post implies that you added it within the first 10 minutes - which would be to a cold engine, and is the wrong thing to do. The oil level should only be checked when the engine is warm / hot, when idling and on level ground.

Are you sure you didn't just completely overfill it?

Thanks Dave

PORKERINO

Thanks Dave,
No I did not overfill the oil, just above the minimum mark. The probleim started upon revving the engine. ALSO, I must add that there is a whitish 'pus-like' residue when I open the oil filler cap!! God knows what this might be?

Yes - but just above the minimum mark when exactly? Was the engine fully warm? Was it idling on level ground when you filled it to just above the minimum mark?

PORKERINO

Hi Dave,
engine was fully warm when filled (very slowly) and checking periodically. Overfill is definately not the cause, what is??

just to clarify for us so we can rule it out completely.

you say engine was warm but was it also running when you were topping up and checking?

PORKERINO

Yes Sir,
Please don't tell me that I totally did the 'wrong thing' by topping up this way!

You did the wrong thing by topping up this way !
The car you bought / we bought has a dry sump system that takes some getting to "know".


The whiteish thick oil / water mixture on the underside of the cap is nothing .

How much oil did you add ?

PORKERINO

Thanks,
Upon checking the dipstick (hot engine-level), there was almost NO oil showing. I added oil whilst engine was running, final mark just above the bottom Mark. Appx. 1/4 can of castrol gtx (will have to go back to can if you need exact quantity). Initially whan engine was running, there was no temp showing on the oil temp gauge, now I recall that when things were 'hellbound' the oil temp gauge was showing 'max'
Thanks and awaiting your thoughts.....

Thanks

Oil temp gauge or the oil level gauge ?

Larry Herman

Interesting problem. On the one hand, adding 1/4 of a quart of oil, unless it was completely topped up, should not have overfilled the tank. On the other hand, you state that the "temperature gauge" showed max after 10 minutes of idling, and unless your cooling fan was not working I do not see how your motor could get that hot. If you mistook the level gauge and it was actually that which was pegged, then the tank was over-full, and it was normal for it to belch out a load of oil. It happens all the time and there probably is nothing else wrong with it.

If however, you are correct in that you had a completely warmed up motor, and the oil was at the minimum mark, and after you revved it it belched out oil and it actually was the temperature that was at max, you have serious problems with your motor. I would have a leak down performed immediately as it would appear that you probably have bad rings and on revving it, the added compression created significant blowby which pressurized the crankcase and forced the oil out. It would also have overheated the oil, pegging the temp gauge.

I'll bet an overfull oil tank sounds pretty good right now. Hope that's all it is.

Hi Larry and all other contributors,

I know for sure that the oil problem (ammount of) is not the issue, the oil temperature as opposed to pressure was max when it started belching out the oil at the top rhs corner of the engine from the air intake filter. By the way, there is a pipe from near the oil filling cap that goes towards the back of the air intake filter (housing) that I suspect the oil came from and out through the filter! does this help the diagnosis any better?
What if I may ask is a 'leak down' as you have suggested?
also, if the rings are worn this means a complete stripdown and re-build. Any suggestions as to the parts I need to stock up on apart from new set of rings?
Finally, does this rule out an issue with the turbo itself?
Please let me know
With many thanks
PORKERINO

Don't panic at this point. Get the car flatbedded over to a specialist to take al ook, it doesn't necessarily sound like a huge problem right now IMHO. Where are you based?
