Need advice (1 Viewer)

Hello Mud members,
I need some advice here. I have a 86 fj60 I bought for 6k a couple of months ago. Body is in decent shape, little rust, 248k miles. Runs good, no smoking or burning oil. Compression numbers 170, 170, 170,180, 175, 180. Several minor leaks. I took it to the shop because of a minor rattle at low rpm beginning of each shift to 3rd gear. Rattle goes away in 4th gear. No rattle cruising and idle. They took oil pan off and said there was a lot a metal. Took off bearings and said they were worn. They recommend new rebuilt engine. They said they can do a bottom end rebuild but want me to sign a waiver to release liability. Should I take that chance and have them do the bottom end or just drive it and plan on rebuild? I really appreciate the help. Thanks

Put 20w-50 oil in it and drive it another 100,000 miles or until it seizes.
Rebuild it now or rebuild it then. Nothing to lose by waiting.
At least that’s how I see it.

Who knows- maybe you won’t even want the vehicle a year from now. It would be a shame to dump a ton of money into it now only to decide — you don’t even like the truck anymore.
That rattling you’re hearing is most likely the transmission front bearing. If it was the engine , it would rattle in every gear.

Slap some new bearings in it, fill it with Marvel mystery oil and run it till it dies.

Easy enoigh to do just the big ends with motor still in. I'd do that, shouldn't. Cost more than about $100 in bearings plus labor.

Any risk of loose metal plugging up something and causing failure?

Oil pickup tube has a strainer, filter must have caught whatever else was in the oil. One can never know, but I say this, them JDM HDJ81 trucks with the 1HD engine, had delaminating big end bearings, so in most cases they are swapped with the motor still in. Consider yourself in the same boat. I'd say go for it.

Thanks. I'm leaning towards doing the work because I can't stand the rattle. They want me to sign a release of liability. I hoping the engine will go for a while.

How much are they quoting for a “rebuild”

 

[bj70bc]

if they are making you sign anything then i would just do it yourself, if it calves then your in the same boat anyways, you just wont be out a bunch of money

Those bearings look terrible.

As stated, get new CORRECT SIZE quality Japanese-made bearings (sorry, I don't know your level of experience), clean the crank very well (there are plenty of Youtube vids on how to do this without removing metal or scratching the CS. Torque the caps down properly. CLEAN the oil pan well, fill with Rotella T4 15w40 or a Non-Syn 20w50 like Valvoline, and she how she goes.

Drain and refill with new oil after 50 miles, and of course, new filter both times.

Good luck.

It depends on what they're quoting you for the work, but don't have them do it just because you hate the rattle. Everything rattles on these rigs.
