compression all over!!!! CYLINDER HEAD REPLACEMENT
I recently bought this 92 explorer 4.0 for dirt cheap. It has a miss and for whatever reason the previous owner removed the t-stat. For $300 I drove it home. Finally got around to opening it up. Plugs looked old, #1 LH side had a tint of green on the electrode. compression test looked like this, using a snap-on compression tester.
All over the place! Wow! I know these first gen are known for cracked heads but WTF is going on here? Also it makes some valvetrain noise that hurts the ears. For $500 I can have a set of rebuilt heads new valves, springs, guides, all gaskets, coolant, and etc to do the job.
Should I go for it and order the heads now? or should I wait until I open it up more?
