Well, spilled my built block the other day after discovering the deck needed surfaced, so I tossed in the stock 6bolt bottom end this car came with. the head is the same one I've been using recently and has new valve seals. the turbo is my wh1c with hx40 compressor wheel and cover and was rebuilt about 20k miles ago when I put ît on.. the block reads good on compression with no large variances between cylinders.
On the initial startup I didn't realize my turbo drain line was kinked and it forced a good amount of oil out the turbine side turbo oil ring. I then corrected that and gave ample time/miles for it to burn clean. mind you this turbo never caused any smoke previously. N
well, at the current time Incan start, idle, cruise the car as long as I want getting it god and hot (up to temp anyway) abs there will be absolutely NoSmoke. But , if I get into boost it will puff a small amount under load, but if I stop the car it will puff a large cloud for a good 30seconds or so then completely clear up, only to start again next time I get into boost.
My question is for those who've dealt with this same issue before... if and when u sorted and fixed the issue did it end up being the turbo rings or an issue with the piton oil control rings? theres no large enough traces in the DP or IC pipes to determine if its the turbo, and compression is good ,so I'm a little iffy as to the true source.
Since the turbo never smoked before, I find it hard to believe 5 minutes of a kinked drain tube fid permanent damage to the turbo oil rings., but my experience with the pistons oil control rings have usually been where they smoke more the warmer the engine got and never cleared completely úp like mine does. So id love omen input fom anyone whos dealt with this before, as I've seen threads about ut, but none where the OP came back to say the fix or ultimate cause was ever tracked down. Which hen I'm done ill fill everyone in for ure
