maybe the oil breather is clogged and spills oil from the dipstick, or evene the oil breather got loose with engine pressure.

rite... ordered a new cam oil seal and a new crank oil seal hopefully that may fix the oil leek problem.

if not wot else would cause the car to throw oil out of the dipstick??

ive replaced the following

leads.... dizzy.. rota arm.. ? and shes still sutttering ive got new plugs for her which im putting in tomoz any ideaS?

oil out of the dipstick is sometimes due to blocked breather - or blocked hose coming from it (or too small diameter)

also the paper crank seal goes too as well as the round oil seal ont he crank.

are you running boost return mod - is oil from your throttle body?

Nope! That won't be doing the contacts in there any good. I'd clean it all out and then check continuity on full throttle over the ECU pins (Haynes has the pin out for this)

new plugs -check

new leads - check

new dizzy/arm - check

Hall sender - checked

oil breather cleaned - check

could it be that i have my knock sensor and the sensor that goes in the intercooler pipe mixed  up?? cause they have the same connection plug?
