I ended up removing it and had the strangest thing in the back part of the seal, a brown paper bag. Besides that being unusual I ended up starting to clean up the cover, what a mess, that thing was caked on grease/oil/dirt. Nothing was removing it easily, I ended up scraping what I could and then went to steel wool, still after about 2.5 hrs it still is not clean, but I did find out that there were vents on the cover, which had never been open before.
My question is what would having those vents covered do? I did notice a terrible smell of gas when I removed the cover which kind of surprised me.
Thoughts?
Thanks
Steve

I'm not real sure what your question is. Some valvecovers had the two little slit vents in the top. If yours has these and someone covered them somehow, I'll bet it was to stop the smelly vapors from coming out and fouling the air in the cab.
If the engine is worn out, these little slits will puke forth oily vapor and smelly fumes. Maybe someone was trying to pass the engine off as one in better condition than it was and plugging the vents was part of the ruse.

Those being clogged can cause or aggravate oil leaks by building up pressure in the system. You should check the road draft tube also. It would be a good idea to pull the oil pan & clean it also. You might save that engine for a while.

The engine runs good and strong even though this was clogged up.
So one question, what and where is the road draft tube ?
Never heard of that one, I was planning on pulling the pan next and once I get the cover back on hitting the entire thing with the pressure washer and some engine cleaner. | | | | | Joined: Dec 2005 Posts: 2,557 'Bolter | | 'Bolter Joined: Dec 2005 Posts: 2,557 | the road draft tube is on the passenger side of the engine.It is in between the distributor and fuel pump and looks like a pipe that turns down towards the ground.See the link for a picture of my road draft tube . road draft tube
