Need moter for vx I bought yesterday. Will trooper work

[mattferguson14]

There are a ton of threads on here about motor replacements. Just use the master search feature. Trooper, axiom, rodeo, even Honda passport and acura slx are all potential candidates if you get the right year. Also try eBay. You can get a nice rebuilt engine for around 2 grand.

Why do you say you need a new motor?

[Jeepsfun]

2nd owner of vx. Said his moter run out of oil and sized up. I'm a cj and excursion owner but have been looking for years for a vx for the right money
It was my understanding that trooper moter wAs plug and play.

Thank you both for taking time to respond about my vx problem

A trooper motor will work but you give up a few horsepower as it is a 3.2 vs. a 3.5. A search as suggested above should give you a ton of info on the subject.

Member "ND92" (Stefan) just replaced his engine and went thru the analysis and decision making on which direction to go. PM him, I'm sure he'd be glad to give you some input.

MSHardeman did the same and could probably provide some help as well.

Ok, just to clear up a misunderstanding on the 3.5L it is a noninterference motor. Meaning in this case you should not have to replace the motor.
If you want to do the timing belt and an upper end rebuild. IE... Heads, cams, timing belt. What is going on when people run these low on oil is that the cam seizes. Rebuild the top end of the motor start it up and drive.

Rebuild your motor. Have it balanced, blueprinted, and all that other stuff to make it better than ever!

I'm confused... ( go figure!)

I understand Non-interference...
..but how does that mean that he may only need to rebuild top end??

Lack of oil is lack of oil...

""ran out of oil and seized up"

...surely bottom end could be fried ?

yeah, I don't see how you can assume it was a cam and not the crank without tearing the whole thing apart. And unless you're going to do it yourself, the labor can add up to as much as buying a rebuilt engine or sourcing and pulling a used engine. Not to mention if you buy a rebuilt engine, most come with some sort of warranty. Some things to think about here..

you are correct in thinking that it could be the crank. how ever the cam should go well before the crank. i have rebuilt a couple of these that have been ran low and or out of oil and it has been the same on all. i just had to rebuild the top end. one of the motors have 15k after the top end rebuild and its still going strong. you can buy a master rebuild kit for $500 plus what it would cost to machine the heads. even if you take it to a mechanic it should cost less then a motor swap.

Is there an way to determine this?

Could you pull the plugs and the timing belt and see if the crank can be turned with a breaker bar?

Sounds feasible..
