I have begun the rebuilding of the 4.2 engine from my 77 CJ-7 barn find project. My local NAPA store in Buckeye, AZ has a reputable engine shop attached and run by an family friend of my wife. Its good to have friends with years of experience to help. I opted for NAPA's deluxe master rebuild kit which is a good value when you get it all at once.
I was pleased with how clean the hot tank process got my dirty block and sheet metal. I had given up on scrubbing and even the pressure wash
Hi, Stuart! Pushrods often get overlooked and can be reused in many cases. I like to roll the original pushrods on a piece of flat glass to check for straightness. Ends can wear, a concern of course...Replacing the pushrods as you have done is a fail-safe approach, and Melling remains a high quality engine parts source. (I always use a Melling replacement oil pump, most often a High Volume design. OEM Jeep oil pressure runs quite high, so a quality OEM replacement pump by Melling is plenty.
