Question Slippery Intake...

i just bought a 1989 SHO with about 70,000 on it, very clean car... never used a drop of oil, no leaks, went 3000 miles without loosing a drop. My girlfriend started the car to move it out of our front yard the other day and a big poof of smoke came out... i figured ok time to do valve seals. However, we were slow at work the other day so I figured id pull it in and pull the timing belt cover to see if the belt had been chaged. Well when I pulled the passenger side crossover plenum off I found that the front side plenum had puddles of oil in it! I am not very familiar with these motors yet, this is the first one ive had. I checked the oil before i changed it and it was a quart low. I see that it has no pcv valve, just a vent tube. The only thing I can figure is that being that I am pretty rough on this thing (its sees 7200 every chance i get :-) the only thing I can figure is that oil is fogging off the valve train and being sucked through the vent, being that the vent goes into the same plenum that was wet... Make sense? An I crazy? Some one let me know...

Thanx
John

Re: Slippery Intake...

That is normal. The condensation of the PCV gasses forms the oil puddles and will turn to carbon on the valves and lower intake.

Re: Slippery Intake...

How much of that carbon will actually turn into deposits? Should I run an induction cleaner periodicly to reduce deposits or will it burn/flake off on its own?

Re: Slippery Intake...

I don't think the intake system cleaners do much good. You would be much better off to remove the intake and do it by hand with Berryman's or non-chlorinated brake cleaner.
