Re: I have a 2004 jeep grand Cherokee limited with a 4.7...
The HO is a high output version of the 4.7. the differences are internal, the externals *should* be the same.
to be sure, though, call an auto parts store and ask them if the 4.7 regular and 4.7 HO use the same MAIN SEAL. this sill ensure that the regular 4.7 will fit a 4.7 HO transmission, as the main seal comes between the back of the engine and the front of the transmission.

If you haven't changed the plugs or had the fuel system cleaned, now would be a good time to do it. The number 1 culprit for rough idles is dirty injectors or plugs. You can try an injector cleaner in a can (or bottle) for under $10 and see if it helps, and then work from there. If there isn't any improvement then if you are able to, check the plugs for any gunky buildup and if you find a bad plug, make sure you replace them all (or have them replaced) at the same time.

Pull the alternator brackets and front engine brackets off until you get to the water pump. You will also need to remove the fan shroud and then the fan. Remove the water pump and then you will see an aluminum cover and that will be your timing cover. remove the cover and clean all the gasket off the engine and the cover. use a razor blade, and make sure there in no oil or grease on the parts where the gasket lies. Put your gasket on, bolt the cover back on with the new gasket and repeat the teardown process in reverse.

HI, It may seem obvious, but sometimes overlooked.... have you checked the oil level, as low oil can cause some strange things to happen! My 96 4 liter would be reluctant to move sometimes, but after I topped it up, it has been fine.
