Still havent got my Jeep back!:(

My 4.7 v8 103000 miles crapped out on me last week. 2 dead cylinders an threw a code for cam timing. What causes it! I've done a lot of research not many answers I'm just scared the engine will need rebuilt. Which I don't have the money for especially on a 4.7 motor so what other motors could you cram in there that are cheaper besides a 4.0 i6 trans and all if needed. Hoping for the best still but we will see!

I6 or the 4.7 v8 would be about the only ones for you. Have they said what broke?

No it's a friends shop an hes pulling the front off Tomorow to see. I just don't understand what makes it do that all of a sudden. It was running fine then just started shaking and crapped out! No loss I oil pressure tho so that can be a good thing.

If 2 cylinders have no compression you are in it for a rebuild.

Think I suggested in your other thread, pull the valve covers and see the valves. If the valves are shot, then no need to start pulling the front cover is there?

I would but I don't have it right now he probably will do it. See I thought it was bad gas or a stuck fuel injector because I just filled up and got like 100 feet from gas station and it clunked out.

If it was fine then all of a sudden not, to me that sounds more like sensors or electrical. What exactly is "dead" in your cylinders?

Should do a compression test, and spark test.
