I can push the plunger all the way in, by hand even.

I thought it was harder to push in after I primed it, maybe it lost its prime.

I'm about ready to drill a hole in the oil pan or timing cover or disassemble my cell phone and drop the camera part down into the engine just to see what the hell is going on.

I can't even think of what could go wrong to create this, nothing, I'm totally stumped.

I mean even if I did have too much tension in the timing chain, what would be squeaking?

There's no damage to the chain, there's no plastic pieces from guide rails, no damage to the vac pump gear, arrrgh!

Anyone want to trade an old Volvo for an '87 300sdl?
