I have a 1991 3.0, which was knocking.
I took the engine from a 1999 3.0 w/ a bad frame but running engine and put it in the 1991. I put the distributor and upper and lower intake from the 1991 on the 1999 engine. To switch the lower intake I had to take out the pushrods and then tighten them back up after.
Truck finally is all back together, I start it, and it is barely running, sounds like running on just a couple cylinders. Compression test on #1 cylinder shows no compression.
What could have gone wrong here? I'm guessing this is a valve issue, since that is the only thing I messed with that I can think could conceivable lead to the compression loss. But as I understand it, the valves on that engine aren't adjustable. The manual had me tighten each one down to 24 ft*lbs, regardless of cam position. Hard to see what could have been screwed up in that process? Any ideas?
