i burn 1/2 quart every 20 miles. the seals blew while i was boosting up over this nice long hill on the tollroad (i had to keep about 5psi on the manifold to keep going 75) and could only stop to check the level because i was on a time crunch with a business delivery. the car was parked until tonight. my friend brought 2 quarts, picked me up and we continued on to work about 40 miles further away from home.
from what i have seen and heard you will get blue smoke from oil burning in the combustion chamber, white smoke from oil coming out of the turbo and burning in the catalytic converter.
also, i am getting oil spray out of the dipstick, telling me that the sump is being pressurized due to exhaust gasses, probably entering at the turbo return line. to the best of my knowledge, the white smoke and the oil out the fill tube would both be symptomatic of a blown turbo seal.
i am slightly frustrated and slightly annoyed with myself. i knew there was too much play on that turbo when i pulled it off. i showed it to Gabe, who was helping me, when we pulled the head off my motor. both he and i thought it needed to be rebuilt. i should have purchased a rebuild kit then, but put it off because i was not having problems prior.
well, everything went back together after doing the HG. you remember the white smoke / steam i had mentioned? it cleared up, then kept coming back in puffs. i think the subsequent puffs were the turbo seals starting to go.
it only finally got really bad today and tonight.
funny it went now, right after i switch to 10w30 after running 20w50 for so long.
i need a daily driver. that way i can continue driving my Saab the way i want to drive it, and still be able to get where i need to go every day. i dont want to drive my c900 in stop and go traffic, i dont want to drive it doing deliveries for work, i do want to drive it on long trips, on weekends, going skiing, in the rain and in the snow (there is no salt usage allowed in Big Bear or on the way up, it would contaminate the local water supply).
i dont think it will ever end.
