  • Suggestions on determining the health of an engine...

    I pulled the engine out of another car to put in my 87. I have a feeling the one in the 87 is tired. Burns oil, rear seal is leaking (Again) doesn't pull worth a shit over 4500 rpm, doesnt even rev close to the middle yellow area, etc. Just seems tired to me. Its a completely stock, non-HO motor.

    I plan on replacing it with one that has very low miles, less than 10k, has a B cam with matching springs (old I know), but has sat for a while. I ran it a few times, but regardless, it sat for a while.

    What can I do to make sure it's healthy before I swap them? Its on a stand right now... leakdown test? If so, is the kit from Harbor Freight sufficient for this? Should I pull anything apart to inspect? Or just leakdown and post up results?

    leak down test will tell you if the rings and valve seats are in decent shape..as far as the bottom end...put a mech oil gauge on it, spin the oil pump driveshaft with a drill on high speed, you should see around 40psi

              So I just got done tearing my engine apart and guess what? The intake upper and lower, STOCK orginal. The heads, rocker arms ect all stock orginal never been touched. Cam is still in the car but if the shoe fits...... Cross hatches clearly visiable in ALL cylinders, no signs of detonation on any of the pistons,
