Puking oil???

[sytyfreak]

Well, I noticed that there's oil stains(spray like) on the garage's floor coming out of the exhaust. Also yesterday a friend was wainting for me to get the truck out of the garage and as soon as it started hes pants were instantly sprayed by the exhaust :lol: :drinking: Does anybody knows what this is :-? ???

Any help will be appreciated.
Thanx

Luis,

It's nothing good, that's 4 sure. My guess would be a blown Turbo center seal if indeed it's oil. Of course if the vehicle is cold it could be condensation.

Ok, checked it and It's not oil. Well, atleast the stains. It looks like when you wash the truck and water gets in the exhaust and then it comes out with alot of dirt. But it hasn't even rained since almost a week ago and the truck hasn't seen any water at all. Also when I start it, some times a puff of smoke comes out of the exhaust...

That's probably the classic valve seal leakage. NBD, not somthing ya gotta fix right away.

Rare GMC oil slick option (a la Knight Rider)? DNR authorized misquito sprayer? Exhaust anti-rusting system?

Mine used to have these installed on it. Shoulda bought stock in Mobil back then. :wink:
