So yesterday I drove for 40mins to see a friend and to check if changing out the cold start valve changed anything; I've been suspecting that it was the cause of an overly rich condition and and when I got to my destination 45 mins away, the idle was really bad. On the way back home I saw smoke in the rear view and could smell oil burning. Not good! I also saw my oil pressure dip.
I made it home and found the dipstick had popped up, and oil all over that side of the engine and on the hood. I researched this on the BB and found that sometimes the OVS can be the problem. I just pulled it, and it wasn't clogged. I had cleaned it good in 2015...but the restrictor in the ovs line to the plastic intake runner was cocked in the line. Something was pressurizing the crank case. Mood is darkening.
Compression was taken a few weeks ago, and I'm 150-160-145-150 across, but I had forgotten to hold the throttle open, so I thought I'd do another compression test. The car started right up but still ran like crap, not the smooth idle I had a few days ago. I warmed it up until it died on its own.
Also, I saw puffs of vapor coming out of the dipstick tube when pulling the dipstick. I pulled the oil cap and saw lots more vapor puffing out, and while revving I could feel a nice breeze coming out of the oil fill. Mood darkening further.
I pulled the plugs, and here's how they look.
So, I do my compression with throttle open and get 190-180-40-175. Crap. I then pour a little oil in #3 and #3 comes up to 175psi. Note that in Sept. 2015 I had 200, 205-160-193 just after the new head gasket started leaking compression into the cooling system between 3 and 4....so #3 has been an issue for a while.
So, sounds like my engine is shot, eh? Rings in #3? I put fresh plugs in and that didn't help anything as far as smooth running. This sucks...
