I've got a bit of head scratcher here.
For background, my front passenger side cylinder hasn't been firing when cold. Symptoms were popping in the exhaust, a top end/passenger side knock, and ridiculous amounts of raw diesel out the tailpipe, all while cold. Cylinder #1 was clearly the culprit verified by disconnecting injector lines.
The heads had a fresh valve job in October, along with pop testing and shimming injectors to 1900psi each, and weeding out all air intrusion.
Here's where it gets a little tricky. I ran the engine without valve covers to check everything out, and noticed there was notably little to no oil coming out of the pushrods on the passenger side, and that the cylinder #1 exhaust valve guide was blowing out a bit of smoke.
The exhaust valve guides have been just been replaced and valves re-seated (again). I'm wondering if my problem all along has been poor oiling of the passenger side head.
My question is, what could cause this? Clogged up lifters? The pushrods were clean inside.
Thanks in advance if you made it this far. The truck has been parked for months trying to figure this out.
