1996 855R 175k Blue smoke on hot start and heavy throttle
Hi All,
After acquiring a one-owner '96 855R back in June I've been battling a few issues.
Oil consumption more than 1qt/1000 miles
New Volvo OE PCV kit/hoses
New Volvo OE turbo drain line (???)
New Volvo OE intercoooler hose (the tree)
New intake elbow with sensor? Long plastic hose
New Volvo OE front O2 sensor
New Eurosport Tuning 3" downpipe with race cat.
When I bought it it threw an O2 code and cat code. O2 was fouled and cat was plugged up.
After changing PCV, oil no longer smokes out the dipstick.
Current issues:
Oil Consumption
Smoke on hot start. Drive car to operating temp, shut off for a few minutes to an hour, and get a good puff of blue smoke out of tailpipe.
I swear it's starting to smoke around engine bay. I'm wondering if it's hitting the manifold but when I'm in gridlock sometimes I can smell oil smoke, and swear I've seen just a bit of blue smoke coming from underhood.
Any ideas? Haven't pulled the 15G and honestly wouldn't know what to look for.

"Smoke on hot start. Drive car to operating temp, shut off for a few minutes to an hour, and get a good puff of blue smoke out of tailpipe."
That is a pretty classic effect of the valve stem seals starting to go out. You shut it off and some of the oil in the head follows the valve stem down to the combustion chamber or top of the valve waiting to be sucked in and burnt causing a bit of blue smoke on start up.
