Re: doing head gasket on 4.7 help

DAMN! same crap happened to me last year after i rebuilt my 4.7... It ran great for about 15min then it took a doodoo.. I had bought some H.O. cams from the dealer and the passenger side cam had to get shipped from somewhere in the east coast... I called them for the pin and they said it wasn't available. And the cam was on backorder indefinitely. So i took it to a machine shop and they repaired it for 40 bucks. The pin is pressed in. I looked locally for the pin but wasn't successful so we actually used a drill bit cut the shank and pressed it in and saved the cam. So far i have about 4k miles and it's running GREAT! If i were you, remove the timing cover to double check the timing marks. I bought a new bolt for the sprocket as well. You can reuse the headbolts as long as they are not stretched. I also reused the head gasket Good luck!

Eventhough this statement is true, the 4.7 headbolts are no torque to yield design. If the threads are not necked down, you can reuse them.

Re: doing head gasket on 4.7 help

New member, first post.

This CAN NOT be the end of the story. I'm fairly certain you got it running, no?

I'm on the front side of exactly your situation, trying to decide whether I want to do the same project. This thread has been very informative.

I have tools, have knowledge. Not sure I have the stamina to deal with the potential setbacks.

So, two questions:

1. Is it back running?

2. Would you do it again?

its running. but I had a hurdle .. my cam pin snapped and bent two valves that set me back another 120$ but all in all. I saved a boatload of cash..I did items which I probably didn't have to like new valve springs. valve stem seals. and gasket kit.....I would do.it again.as I now have knowledge and know how to cut corners and get it done faster and cheaper .... if u need help u have a lot of help on this forum if u have extra money get your heads pnp or headers ported. as u have access

Re: doing head gasket on 4.7 help

I am in the process of reinstalling my passenger side head on my 2006 Jeep Commander 4.7L. I left the timing cover on the engine as I don't have the puller needed for the crank pulley and hoped to save some steps and time. Today while putting the head back on the engine the secondary chain for that head fell slack and popped off the idler sprocket.

Does anyone have any suggestions on how to get the chain back on the idler sprocket? I have the head sitting on the engine but not torqued down at all. I just finger tightened the large diameter headbolts to keep the head from accidentally coming off. I really don't want to take the front cover off because I don't have the specialty tools to remove or install the crank pulley.

Thanks for any help in advance! Oh and sorry for reviving an old thread.

Take head off and try to snake it on
If you have 0 luck then get a regular 2-3 claw puller remove the pully and remove cover. At that point replace the water pump with a metal impellar and buy a new cover gasket
