Went ahead and installed new timing gears, chain and tensioner.
Remember, the trick to the gears are to put them on at exactly the same time with the chain. Seen a lot of people struggle with this for some reason.
Very nice pics and description. That before and after cleaning shot is just plain cool....
I really need to do this to my 200k+ mile 2003 4.2L. It has a tiny valve cover leak. But I don't have any covered work area...just the trees out in the yard. But my end goal is to swap in a 5.0L Coyote. So my old 4.2 block may turn into an additional traction weight for the light rear end.
The heads were not in horrible shape but I thought since Blakes was already cleaning it up, I had them go ahead and do a complete valve job and pressure test.
Then got ready to get them mounted.
Next was doing the torque steps on the head bolts. This is a lengthy process. Notice the paint marks on the bolts. The last step is to pull the bolt another 180 degrees. Marking is a must.
Added the pushrods and rocker arms.
Rocker arms get tightened down to 29ftlbs.
