Well I started a thread in the Ram section about my 4.7 dropping a valve seat and taking out cylinder #2. I am going to continue it here, where it should be - but this should be of interest to ALL 4.7 owners.
Finally got the heads off (and I'll be honest - this will be my LAST OHC modular engine!) I've gotten heads off of 4.0 I6s in an hour and a half. Took my over 7 hours to get the heads off this SOB!
As expected the aluminum head is toast. As suspected the piston in cylinder #2 is toast. What I found that I did not expect was that BOTH heads were done! Seems the valve seat exploded and debris went up into the intake manifold and made it to the other head.
and I don't think this piston is re-usable, LOL...
So I got a local quote from a reputable shop on re-manning the heads and re-pressing all valve seats at $380 if I supply the seals. Found an all-inclusive master overhaul kit for $700 to the door - WITH 8 new, balanced pistons (might as well make this a TOTAL rebuild). So about the only other parts costs I'm gonna have are water pump and oil pump (again, the originals are ok, but with 102k on 'em I only wanna do this once) and then just plugs, fluids and filters...
I hope to have the kit tuesday so I can take the valve seals out and get them and the heads to the shop so I can get started...
