Digifant Tuning
« on: 16 February 2008, 18:33 »
So went to tune up my 8v from Rubjonnys guide. After getting the engine up to temp, removed the pipe from the flying saucer, plugged the intake hole,then started the car. Revved to 3grand and oil literally started spewing out from rocket cover gasket all down the front of the head. So I plugged the pipe back on to the intake and it was fine. Tried again and same thing, can't go any further cos i'll loose all my oil and im sure this isnt right.

I must be doing something wrong but im sure thats the way to set the CO2 levels up from rubjonnys guide.

Any thoughts i'd be grateful, cheers

It sounds as if you have a case of crankcase compression. Do it again and remove the dipstick. If you have a howling gale from the dipstick hole, then you may have a piston or piston rings issue. Sorry to be the bearer of bad news, but what you have described does not sound good.

Crankcase compression? More than the head I'm afraid. :sad:

You could try giving it a dry and then wet compression test to give you some idea.

Where was the oil coming from exactly? If you had this amount of oil going into the PCV valve then surely you would have noticed by now in the form of plumes of blue smoke flying out of your exhaust.

odd!  try taking the PCV off completly, perhaps its buggered inside and only opens when vacuum from the inlet sucks at it?
