Rebuild time

[retro46]

My 1994 FJ80 needs at least a top end rebuild…. Looking for opinions about that versus installing a remanufactured engine?It has 300000 miles on it.

Remans are generally held in low regard around here.

Remanufactured Engines

Is there a good supplier for reman’d engines? CruiserParts has questionable quality/service, Jasper (from what I hear) is in the same boat, and the slew of pop up suppliers seems to be worse, at least their sales departments haven’t inspired confidence during my correspondence. Everything on...

Personally, assuming your engine is good otherwise, I would rebuild the top end. If my entire engine were blown, I would consider a reman under the assumption that I would be doing a V8 swap or some other drastic change soonish.

My advice is do the top end.
when you take the head off you will have a good indication of the bores and if well maintained should be fine, visible cross hatching , no score marks etc.
Its not a difficult task but dont rush it, use OEM parts and you will be right.

I did the top end (HG) on mine at the same (480000kms) coming up 5 years now and no probs

Good advice in the previous posts.
I took a different route.
1 year ago I was up to my elbows in a complete rebuild (main bearings, rod bearings, pistons, etc., etc.)
I broke every rule in the book. 372k miles running good (passed CA smog). I fixed tons of stuff that wasn't broken, on purpose.
Loved every minute. I wanted, and got a "new" 25 year old beast.
A) I don't have any nagging worries now, and
B) I know everything inside and out.

Downside? Wasn't exactly cheap!!!

I'm rebuilding mine right now with 288k. It's been easy going so far, just waiting on parts to get delivered so I can take it to head shop.
