Hi gents hey just a quick question and a little info to share. I have a 94 "Mark Hate" That I just replaced the head gaskets on with the engine in the car. 200k on this car and no lip in the cylinders! Amazing! I bought this off the original owner he ran Mobil 1st from his first oil change. So a couple things I learned alone the way. One is that Vrcm are still available 86 bucks with your old unit They are not called VCRM by the parts houses but rather relay control modules.
Also overheating problems can be tricky but in my case the car had a thermostat that was only opening a short distance I found this out by dropping the old and new thermostat in boiling water (easy test).
The car over heated while being driven by a friend this cause the head gasket to go away. If you remove your serpentine belt and crank or start the car for a minute and you have pressure in you coolant tank then you have cylinder pressure in your coolant. Easy test. My was bulbing as I cranked the car lucky it was head gaskets and not a cracked head or cylinder.
EGR tube can be really hard to find.
Knock sensors are easy to break. I broke both of mine. OOPS!
Spark plug wires can be a bastard to get out of the valve covers
Forums are your friend.
The question I have is will the knock sensor being disconnected make your idle not happen I have to hold it at about 1200 Rpm to keep it running.
I suspect it sill still idle with bad knock sensors and that my real Problem is the spark plug wires as they were a real pita to remove. Any Knock sensor input would be great thanks. Well I hope this info help someone because I've gotten a lot of help from the forums Thanks
