I have a 1994 850 wagon. I am in the middle of changing a head gasket. My question is in regards to the cam cover. I have improvised the tools to hold the cams locked in the cam cover.
My first question is in regards to the liquid gasket compound that gets rolled onto the cam cover.
1. Do I install the cover with the liquid gasket compound wet or let it dry?
2. Do I have to get the special volvo roller or can it just be brushed on thin with a small brush?
I just recently changed the head gasket aswell, make sure you get the cylinder head resurfaced. About the cam cover, I just used some copper gasket spray and put the cams on the head first, then put the cover on. I saw the book says the other way around but it seemed like too much work to hold them inplace on the cover then bolt it down.
Now the problem is their is no engine rpm signal coming to the ecu so its being shady and not firing off the injectors. I cannot find where the rpm signal source comes from, im thinking the Cam Position sensor but I doubt it, I would have gotten a CPS code.
I have a 1994 Volvo 850, changed the head gasket and now the fuel injectors dont fire off, sparks good but no fuel.
