There are so many things going on with this truck. 1988 25.9L
1 - Need help with the CEL code
2 - Help with why I'm spewing so much oil now
* CEL - Code #54 - Intake Air Temp or Vane Air Temp signal high. I spent several hours last night trying to research this, and I came up with nothing specific, just a lot of things I could throw money at and hope it corrects.
* The other night while bypassing my bad heater core I noticed the PCV valve was cracked and almost in 2 pieces so I replaced it last night. Started it up, and it went into a very very low idle. Checked my codes again and still have the same #54. After giving it a little gas it would stay in low idle and not shut off.
This morning, about 3 miles up the road I started to notice smoke venting into the cab of the truck (burnt oil smoke). Then smoke everywhere. Oil is coming out of my right side valve cover (which the gasket is bad and I knew that). I've had very little oil leaks in this truck from the valve cover (I've only has this one for 3 months now and haven't preformed all of needed overhauls yet).
I'm not a mechanic, and I'd give myself a 4 out of 5 for troubleshooting so I'm going to really try to not sound dumb here - On the right valve cover there's a breather. On the left is the PCV valve. I work in the boiler industry and I'm fairly familiar with combustion, gas/oil systems, etc. The PCV valve is like a check valve, and if both sides are 2 different chambers why are they not the same? Why would you have a check valve on one but not one on the other?
