My new logging boss up on the Rim has a nice looking 05 yellow TJ that he originally purchased new with a hard top and not a scratch on it. It only has 69000 miles on it. He was headed to work about a month ago going about 70 mph and heard a very loud screeching sound and the engine locked up. He had it towed into the Dealer in Show Low and they told him that the oil pump drive gear had failed,"OPDA" and that he needed a new Mopar engine installed. Well are you ready for this $5395 for the engine plus mis parts, labor and towing totaling about $7200. He wasn't very happy about it but told them to go ahead and fix it, because he planed on keeping the Jeep long term. He got it back a couple of days ago and it runs great, but doesn't that seem like a lot of money?
I asked him why he didn't look for a used engine, but he said that he didn't want to purchased a used one and have the same problem all over again. I think that it's terrible that it cost that much to replace a engine! This really surprised me because I have always heard that the 4.0 engine was almost indestructible! He says that he always has the oil change about every 5000 miles and uses Mobile 1 synthetic. Maybe he should have had it changed more often.
He can still have the same problem with his new engine as he had with his old. The OPDA is a weak link in the engine. As far as I can tell its practically the only weak spot. There is a kit you can buy from a guy on another jeepforum that retrofits onto the OPDA that corrects the problem and you shouldnt have any more worries (with new or old) Do a search on google for jeepforum and go to the TJ section. Im not saying to leave this forum just do some research.
Also this problem is only on the 2005 and 2006 model years.
Hope this helps.
Your boss has got money to burn.Ask him for a good christmas bonus! Before with his spending decisions the cash will be low.No,really he picked the most costly fix.With his lack of fixing knowledge.The dealer probably installed a used newly painted engine
I did not see his invoice from the Dealer, but only what he has told me and that it is a new Mopar engine. He said that the Dealers normal warranty is 12 months or 12,000 miles which ever comes first, but because it was a complete new mopar factory engine, then he gets a 3 year 36,000 mile warranty. That is another reason that he decided to go with new.
My Jeep is a older model and I'm hoping that it doesn't happen to mine. I don't have that kind of money so would have to look for a used engine from a salvage yard. Scary just thinking about it, because it is my only transportation to and from work.
