New member here, Hi!
I have owned multiple Jeeps in the past and even another with the 5.7.
Long story short.
I purchased a 2006 Commander last week with the 5.7 Hemi, Limited and QD2.
It had been parked for a while but drove great and no major issues that we could see.
My son drove it the first day and it likely overheated (very little water left in the radiator by the time I got to it).
It won't start. Compression test shows 4 cylinders with 0 compression.
SO. I believe I am replacing heads but have not removed them yet.
I have read as much as I can on this forum and plenty of others over the last few days and here is what I am thinking/asking.
1. For me to pull these heads and replace with a remanufactured units is going to be about 1K give or take. IF I go this route is there any reason for me to replace the rockers, push rods, head gaskets? I would probably replace the head bolts anyway. EVERYONE says that the new ones won't have the same issues! How can I prove that?
2. What about putting the 2009+ stock heads? This gives me the updates in valve seats, lifters, etc? then replace push rods, rockers, head bolts and head gaskets? I assume? Not much more than the first option but I should have the best of in head reliability correct?
3. IF I decide to go with upgraded heads (Several aftermarket options) it will cost much closer to 3K give or take $500. What would get with the extra money? extra performance is going to be negligable? better reliability in the future? maybe? IF I go this route I assume it would probably make more sense or even necessary to replace head gaskets, push rods, rockers and head bolts. ANYTHING I am missing that you might recommend?
Keep in mind I have not owned the car for a long time and this is a 3rd (or actually like 5th) car for the family.
Any experience and insight is appreciated.
Michael
