Hey all...Newbie here (to the forum, not nec the pathy). I've read numerous posts and haven't come across anything like the probs I've got going on. I'll try to keep it brief!
Problem rig: 1993 xe manual with about 175k.
Oct of 08: Shattered #4 piston rod and piston. Valves left "smilyies" in top of what was left of piston
Machine shop said block was ok, but crank had to be reground.
Machine shop repairs and work:
*bored 40 over/honed
*assembled short block with reground crank; orig 5 piston rods and one salvaged from a '94 motor; new pistons; full short block and flywhl balanced; new oil pump; told me block did not need decked
*Installed JWT S1 cams and heavy duty springs
*new guides and stem seals
*ground valves to correct installed height
*complete valve job
What I did:
*Assembled and installed engine with new cap, rotor, taylor 8mm wires, ngk plugs
Probs I'm having
*180 PSI of compression all around except for 130 at #4(the one that orig broke)
*runs rich and smells like gas
*#2 cylinder fouling plug (black soot) and not firing/hesitation and rough idle/bad mileage
*lifters on 2,4,6 clicking loudly!
*rear main seal appears to be leaking
ECU shows no trouble codes
Local shop wasn't able to diagnose any probs except #2 cyl not firing
I've swapped injectors, plugs, wires and nothing seems to help. even installed new cap and rotor again. Cleaned MAF and sealed up a couple of bad spots in air intake tube. This seemed to help, as did the new plugs, but it soon returns to missing and hesitation. I plan to test for vac leaks with carb cleaner. Any other ideas greatly appreciated!!
New motor has about 900 miles on it.
