Sorry for the vague title.
Back ground, its a Bj60 with a 3b, turbo with t25. Rebuilt engine a year ago, 40k kms on the rebuild, replaced to mls head gasket 20k kms ago. 495K kms on the truck. Cylinder head was not rebuilt. Running 10-12 lbs boos, egts under 1000.
Went up a mtn pass on saturday (highway 20 in Wa state) not a huge pass and did about 12 times last summer, with never a problem.
Noticed was running warm going up, but not terrible, was a warm day, had AC on off and on. When I got to top, I stopped for kids to play in the snow, and let it idle to let the turbo cool.
Noticed right away idle was slighlty rough, like missing, not terrible, but definitely there, and a fair amount of blue smoke. I tried to pretend to be happy while the kids played, and let it idle 5 minutes, it continued to do this, not worse or better. Then shut it down. There for probably an hour, and with restarting was still doing it. No knocking or anything else, just a mild rough idle and blue smoke, like if it was a cold start. I had no choice but to drive, so drove a little ways, stopped and it seemed better, but still slight blue smoke.
I drove the 200kms home, and no problems, normal temp, power, etc. It didnt do it when I stopped later, and hasnt after driving it several times yesterday, and a 60km drive this am, it was fine.
Any ideas? I drive this everyday, and never had this before, but has me worried.
Following the other thread on here right now with the 13bt with the rough idle when warm.
A pic just for fun.
Thank you!
