Outer Limits 4x4 Board

and has any body had any problems with 1 HZ motors
If so what
and at how many k's

mate of mine cracked a head on his, it's still running.

but he does run more than twice the amount of turbo boost people usually run safely... so may be a problem due to modification

you dont know how many k's it had on the clock

between 200-300 thou. can ask specifics next time i see him
(may be weeks though)

Mad Cruisers 1hz went up to 450,000 then blew up after dunkin it in water.

My father in law's 1hdt spun a big end bearing at 350,000

tuff80's old 75 that i towed down from gold coast for him after he bought it had 280,000 with a big end bearing failure.

TOM

My old mans has done 380k and its still going strong. I also know of at least 2 that have over 800k

dads has done over 500 000 and all that was needed was the injecter pump done due to the bp thing
goes really well

Have done 346,000 and it runs like a newie. Can feel a gear box rebuild coming on though.

Thanks guys
i heard of the big end spin and i am just trying to find out how regularly it happens.

big end is usually 1hd-t's. apparently toyota used cheaper bearings in the early 1hd-t's (ex toyota service mechanic i used to work for, loyal to the brand still, just let me in on the little issues)

i've got a ihz thats done 420k still going strong. had 16psi thru a big cooler since 220k and still loves it. wouldnt have anything else.

btt

Big end's usually go when oil pressure drop's all u need to do is put a new oil pressure relief valve they are cheap and usually bring the pressure back up.

300 k just clicked over - runs great - depends entirely on the frequency of servicing and quality of filters!!

I know of one with over a 1,000,000 on it and only had minor rebuild at 750K...

I'll let you know once I turbo and I/C it and chuck 12 psi through it for a year or two....

Mines done 404.000km and drives as good as my mates that has 120,000km on it. Love it.

Mines done 370000k's and still uses no oil and gets 7.8kml running 33's. Staeting to get a bit grumbly in 4-5 gear so a gearbox rebuild will be on the cards soon..

Mates 1HZ has done 230,000kms. Last 40,000km with 1HD-T fuel pump, turbo and cam. Smashed the cam 10,000 ago and rolled in new bearing shells at the same time. Runs variable boost....about 12-20psi depending if its competition or highway running.
