Custom HZJ79 from parts, built in the US! (4 Viewers)

[swamprunner]

Me too...just busting your balls a bit.

In all honesty it would be awesome to have all the correct parts new from toyota. I would wager a guess that ALL the correct parts that attach to the firewall/interior would cost over 10k new from toyota. Simply out of my league but it sure would be nice and easy to bolt a bunch of shiny new parts in.

Wondering who got that 76 series that was for sale on ebay and here. Hopefully they don't just use the driveline and discard the rest. There was a lot of valuable stuff there.

Well it is almost Christmas.....just how big is your chimney?

I'm pretty sure the head gasket just blew.

The engine overheated over the course of about two minutes and the coolant in the overflow bottle turned brown and cloudy; it was clear and green two days ago. I had to get to work so I didn't have time to do anything to confirm, will drain the oil tonight when I get home. I was half a mile from home when it happened, it was hitting temperature red line just as I pulled in the driveway. Wife drove me to work.

Who's the guru for 1HZ rebuilds in the US?

No way! Mud member Lynchmob in Portland, Oregon has an excellent reputation.

Whoah....

Poser isn't too far away from you...though I'm not sure if he does 1HZ's....

X2 for Chris (lynchmob) on diesel rebuilds.

Chris would be my first choice. Futhermore, he is fair, honest and will communicate with you. Shipping cost is worth the guarantee of a solid rebuild by Chris.

Sorry to hear of the bad luck, yooper.

That sucks.

damn. if you only got to the bottom of the red line you are probably ok and the hg might even be good. when i lost the hg in the 80 i went well up into the red and the block survived fine.

first off, look for a pinhole coolant leak as the cause. if that is it, you may get away with this.

brown and cloudy coolant makes no sense to me unless the block was not properly flushed before installation. the truck would originally have run with toyota red. the block plug should have been pulled and the heater core backflushed before they put green in it because those two do not mix.

The truck came to me new green coolant and the coolant has been clear and green until today. It was clear and green two days ago when I checked it.

It's probably brown and cloudy because it's been filtering partially burned diesel exhaust like a giant hookah pipe.

possibly. can you smell it? if you lost coolant you might have sucked some old coolant out of a dead zone in the engine that normally does not circulate.

i'd look for a coolant leak. if there is one, you have a chance.

I didn't open the radiator yet, will do that tonight, but the overflow bottle has slightly more than usual in it, maybe only because it was overheating.

I will do all the head gasket tests tonight when I get home from work.

Brown or gray cloudy coolant is typical of oil in the coolant.

 

[crushers]

brown can also be rusted bit letting go inside the block tainting the antifreeze to brown ...

sorry to hear ... new or used engine?

2004 mine truck engine, 66000km on the odometer, who knows how many hours of idling...

I've had mild (but more than I think is normal) smoking on cold starts for some time. I was planning on waiting until spring to have a professional look into that. It was probably the same problem.

The coolant was perfectly green and clear two days ago.

Four more hours or so of work before I can go home and figure it out....

 

[ForealBoreal]

Maybe get an oil analysis and a coolant analysis.

Flush that coolant system like crazy and maybe it's just s*** from inside the block
See if you can catch or filter the water you flush

A head gasket shouldn't be too much of a pain in the ass being your worst case scenario
When was the water pump done?

Overheating will cause the overflow to be more full because the coolant expands and has to go somewhere. You should hit the auto parts store and pick up one of those tester kits. You either suck up some coolant into a bulb and it tests it or stick a test strip down in there and it tests that way. It checks for exhaust in the coolant. Easy and cheap way to test and you don't have to tear anything down.

Yeah i know about the overflow.

Good tip on the test kit, I didn't know about that, thanks. I'll do that if I don't see obvious bubbling when I start it when I get home...

 

[semlin]

keep in mind it also is going to bubble if you have a lack of coolant somewhere in the system.

if you smell or see exhaust gas you will know you are deadmeat.

I edited the above post to include a link. It's not fool proof but it should help with the diag.

 

[Sam Stewart]

Is it smoking at all? Not sure about diesels but gas engines will have some white smoke sometimes if it's burning coolant. Usually the exuast smells kinda sweet like coolant too. (Not that you should inhale exhaust fumes! You can usually tell from pretty far away.)
