Just trying to help a friend: valvetrain busted
This is a long story, but let's just say I've got some friends that are in a bad way financially (lost his job awhile back). They've got a 2003 Jeep Liberty Renegade w/169K that's been out of commission for 15 months; a CEL came on one day and a loud tapping started coming from the motor. Dealer wanted $4K for a new 3.7L, and that just wasn't doable. So, I said I'd take a look...
We towed the Jeep to my garage yesterday, and tonight I pulled the driver's side valve cover to find a serious mess: Four rocker arms bouncing around, one valve lifter just laying in there, and three of the four cam bearing caps were basically toast. Of course, there were chunks of metal all over the place, so I spent a lot of time trying to remove all the bits with rags and the shop-vac.
I'd really like to do whatever I can to help them out, but I need some expert repair advice! What are the options here? Can I install new rocker arms and bearing caps, change the oil, and cross my fingers? Are we looking at a new camshaft or even a new cylinder head? What to do?
Nobody's expecting this thing to get back to 100% again. They just need it to be drivable so 1) they can have transportation again OR 2) they can liquidate the vehicle and move on...
Sorry for the long post. Appreciate your time. I've got some photos I may upload later, if that'll help.
