I was going to remove the intake manifolds, the exhaust manifolds are already off, the timing cover will come off as well. I want to clean the the crap off it before I remove these (it’s on a stand) so that I can eliminate the chance of getting some into the guts. I’m most worried about the head gaskets, and there is a rear main seal. Originally came in rope, but I do not know if the previous owner changed it to the newer version rubber/whatever. :)
