Visible Exhaust Smoke- Flunked Emissions

[Jobe Tichy]

[ Converted text/html to text/plain ]

Would a blown turbo seal also have a correlative effect on lower oil pressure?
I just drove 300 miles yesterday in 95 degree heat and saw that my oil
pressure, after the oil being hot (110ish plus Centigrade) for a long time,
would read 4.5 bar but not as high as 5 when cruising.   I first disregarded
this as being really hot oil from the outside temp and thus less thick or the
valve in the filter possibly blowing off, but not a turbo seal.  I have
170,000 on the original turbo, and notice some smoke on start up but not at
idle.  I also passed a stand-still emissions in Washington State no problem in
March and pull 1.7 also.  Not quite sure what's going on in there???

Thanks.
