Howdy, I got a 07 h3 at a good price from an auction to fix up. Nice body and underframe. Engine is rough. I didn't spend a lot of time diagnosing but it's got a knock and noisy sounds like lifters. I've read a lot so far about them. I think it would be better if I find a new motor and replace. Anyone here r&r a motor from h3? I haven't found any info yet. I know what year and model it can come from. Any info or tips would be helpful.
thanks

Welcome. Easiest swap would be another 3.7L I5 so so you don't have to worry about other components. 5.3s are cheaper to buy, but not to install. I believe Reloader did a 3.7L swap in 7 hours when he was a tech.

Thanks for the welcomes! I'll be looking ( have Been) for the same year 3.7. As stated, I have found engines but they are like 2200-3000 for a motor that has well over 100 k on them. Most from colorados. I really don't want to get into a rebuild because of the time factor. So I guess I'll get the best for the money. Anyone know what service manual is out there that would give me a guide for the r&r.
thanks again
