When Do You Rebuild the Engine? (1 Viewer)

Have a knowledgeable mechanic make the decision for you.

He will do a compression check including a leakdown.

Check the oil pressure with a master gauge.

Combustion gas check in coolant.

Want to go deeper, have the sump pulled and mic the big end bearings.

I do the above without dyno for about 140.00 euros or 165....ish USD?

And if you really want to go overboard, run it on a dyno, and compare with original specs and get it tuned while there.

I was mistaken for a mosquito abatement truck as I went fogging the whole street up with blue smoke... maybe it's time?? Lol

While good in theory, you have been on 'mud long enough to know "knowledgeable" mechanics in the field of Land Cruisers is far and few between. Look at the countless threads here unfortunately those that took their cruiser to their "great mechanic" and we watched the aftermath unfold.

I completely agree, and as the OP made a conscious decision to ask for help from this forum, and if he has doubts about the condition of his motor, then his next post will no doubt ask for help with recommendations from knowledgeable and respected 'mud' members, where he can find the right mechanic in his area to carry out the work.

Just looking for guidelines, nothing more. Curious what 'rules' people follow on this...

I think it is best done on Wednesday?
 
rebuild it when needed, "if it ain't broke" applies, Mine has 210k now, I rebuilt the top end at 190k because I was adding a supercharger and it turned out I had 3 bad valves. It ran considerably better after the top end rebuild. I won't touch it until it stops and or loses so much power it is no longer usable as is. At that time I will take it apart and rebuild it myself while farming out most of the work to a machine shop, ie: block and head dropped off at a machine shop.
 
it just depends if you want a fresh engine with zero miles or if you want a pulled engine with 150k or less.

ive always thought waiting until an engine dies puts you at the mercy of the engines schedule.

Most 1fzs start to give signs of getting long in the tooth-like oil consumption or decreasing compression numbers as they age and rather than being at the mercy of your engines demise—i would much prefer to have Robbie A. build you a fresh 4.6 from a local to him donor engine while you are driving yours around. Or locate a low miler and have it sitting in your garage so you can do the phh and cooling system items so that its ready to go ON YOUR SCHeDULE when you want the change to occur.

Its much nicer to be able to choose when you make the refresh occur vs waiting for a random snafu thats sure to happen at an inopportune time which can add to the costs.....or worse yet have you sinking short term bandaid fix money into your dieing engine.

What shop is Robbie A. with?
 
I think its called Pink Panties Offroad or something in Colorado. :) Or maybe Adventure Offroad. Robbie Antonson . If you want a zero mile engine ready to drop in and go for the next 300k miles he is the guru for the job and probably the only chap many members on the board will let fondle their engines.

One thing that has not been addressd is the OP's wealth or spare capital, and it is not for me or anyone on this or any other forum to discuss it either.

So aimed at all, if you are particularly careful with your bank balance, or about to drop a load of coin on a new kitchen or roof then the question is valid, of course, if your rolling in cash then sure run it into the ground, hell you can afford to have it air lifted right out of that trail canyon, and order using your latest sat phone to order a new crate motor tomorrow.............right?

I honestly think it is a valid question, and deserves valid and dare I say it, sensible snswers?
