Well, it hasn't thrown it yet but it is banging hard enough that I have parked her on the sidelines until I can repair her.
Money is a huge issue, but I hate to just throw another used 2.5l in without making some improvements of some kind.
If you were in my situation, with money being tight, what would you do? I can probably get another worn 2.5l from a junk yard and swap it in, but I am worried about the unknown condition of that engine. I would like to drop in a 4.0l but that could get more expensive couldn't it? Are there other options that won't cost a ton?
If youre not pressed for time and since you said you're short on cash. I'd say pull it puti in on a stand and rebuild it. If the crank is not trashed, bearing sets are around $100 for mains and rods. You can take your time do do it a little at a time. If you can do it yourself you'd have less then $500 in part. Sometimes you can get away with just reusing your old crank, but it's always good to to have a machine shop check. If it needs machined they can also set you up with the appropriate undersized bearings.
If it's knocking the Crank Shaft needs to be reground. The question is why did it start to knock?
No oil pressure, just worn out because it has 300,000+ miles on it and been taken care of, or very late on oil change, this all can tell what all need to be replaced.
It is definitely knocking on the low end. The noise was very clear at the oil pan when using the mechanics stethoscope. The odometer reads 92k, but I suspect it has rolled, especially with this damage. The Jeep is in fantastic shape so I figured the mileage could be correct, but now with this knock I am beginning to believe it has a lot more miles. The oil has been changed regularly.
I am going to start looking for used engines now. Being down one car is making life difficult for my family.
I have located a replacement in a u-pull-it type yard for $500. It is already pulled and had a compression check and they guarantee it for 90 days, so I should be covered if I start it up and it turns out to have a bad bearing as well, or any other major issue.
I am going to be doing this swap in my garage. I have basic hand tools (full set of wrenches, ratchets, sockets). I will have to rent a lift. What other items, besides fluids, should I be buying for this operation? Are there any funky tools I should have on hand? Other parts I should be replacing while I have the engine out? I am thinking it will be smart to check out the clutch.
