RE: Poping 258 engine Any suggestions



As was mentioned, check pushrods/rockers (and the manifold for vacuum leak), 
but it could also be cam walk. You can fix that with the cam buttuon and 
timing cover off an early 4.0L. '87 to '90 (and also grab the exhaust header 
while you're at it) A crack or carbon track in the dist cap or ignition 
module about to die will do weird things too. On my '83 Cherokee, I took a 
good running motor from my Eagle and put it in, then when I tried to start 
it, it backfired and wiped out the starter (broke the nose off!) Previous 
owner of the Jeep had put a brand new 258 in, and broken 3 starters and gave 
up on it.
   I slapped the module from my Eagle in along with one of my spare starters 

and it fired right up!
