removed from running engine, passes pressure test, cracks are not causing any issues at this time but I decided to replace it just in case they grew. i didn't measure the guides but the valves still felt tight 198,000 miles. warped .006" (spec is .008" or less) could be fixed with pins or...

Decent clutch suggestions for 1hdt that is pretty much on par with oem not after somthing with too much pedal pressure

Anyone know of an HDJ80 for sale? Or clean HDJ81. Would prefer the LHD but not a killer. Thanks in advance.

Are there any options for the HDJ80 / 1HDT to mount an ARB compressor?

For Sale: 1992 HDJ81 with a 1HDT factory 4.2L Turbo Diesel ***IMPORTANT MESSAGE*** - Truck Norris was not built to hang out at the mall or go to Costco on the weekends with your old lady. I built this rig for Elk hunting, Camping, and anything else mother nature can throw at you. The time has...

removed from an engine I bought from great seller chapelgate. has new pipework, gaskets, hardware as shown. the engine it was removed from was said to have 198000 miles, 1994 model. you would think that somebody would put all the new parts on the turbo if it was being rebuilt but I cant confirm...

Hi guys and gals, longtime lurker, first time posting! I'm looking to replace my wife's daily rig, and I'm looking for thoughts and opinions from ya'll. She currently is driving a '91 3FE cruiser. It's pretty thrashed, mostly (but not completely) by previous owner(s). I don't have the time to...

My first post, I have had my 1hz engine drilled and tapped for oil feed and return. What I'm looking for is the fitting that goes into the skirt fir the oil return same as 1hdt. The part number i found and ordered is 12258-17010 which doesn't have a thread, looks like it needs another part. Any...

Hey guys I just picked up a 1990 HDJ81 at auction. I’ve got a ticking noise that sounds like it’s coming from the bell housing, oil pan area. I’ve tried narrowing it down to a specific but unable to. If I accelerate it gets faster. It does almost sound sporadic and not like a rod knock...

Hello all, How on earth do i remove the TPS from the injection pump? I cannot remove the screw closest to the engine. Is there a special tool? Ive developed shifting issues after an injection pump rebuild (very late shifts, extremely sluggish) and i suspect the TPS was reinstalled incorrectly...

*SOLD*1HDT Engine, just under 200,000 miles, runs perfectly. I purchased this from Chapelgate here on MUD. It's still in the original shipping crate. I'm only selling because I sold my 40 that I was going to put it in. Prefer to sell locally, but could probably ship to lower 48 through...

Hey how’s it going I’ve bought a 1hdt to replace the 1pz in my 77 series and am considering my gearbox options. Will an h151f from an 80 fit in the transmission tunnel fine? I’m assuming I will have to do some fabrication regarding the crossmembers and lengths of drive shafts? Or has anyone used...

I'm considering buying a 1997 80 series with the 1HDT engine. It has 126,000 km on the clock. Based upon reading various threads here, it is a good idea to inspect/replace the BEB's. Can that be done with the engine in the truck? Should the rod bearings also be replaced at the same time...

Have a 91 with a 1hdt. Currently in the middle of pulling my old injection pump out b4 putting in an upgraded one, was lining up the timing marks and the 2 timing belt pulleys line right up with the marks but the crankshaft is slightly off of its mark. Never had a noticeable issue with the...

Hi, I am wondering if anyone knows of a place that still sells the Safari Intercooler for my 1994 JDM Land Cruiser VX81 Ltd. I know that they are discontinued, but am curious if there are maybe some places that still sell them ? Thanks, Carolin

HI All , Ive got me an 84 chev g20 van into which Ive just installed 92 or so 80 series running gear in it, including axles, 1HDT and hydro A442F. I got then thing running on the weekend and for whatever reason it wont fire at all when cold, a quick shot of ether and it lights straight up and...

I need a new exhaust and can get a full 304 stainless exhaust in 2.5” for half the price of the same in 3”. My motor is currently stock but I will soon be adding an intercooler and lightly tuning the pump for the best balance of power and reliability I can get out of the stock turbo. Probably...

Do you think this is a leaking turbo? I was told to get a catch can and it should prevent this from happening. However, when I installed an Intercooler, the hose from the intake crossover pipe to the turbo had some oil residue. Thanks!

This is a great mod if you’re running a bigger turbo, injectors or both! Same geometry as the ones we used to carry, but with some modifications to the molecular structure of the steel itself. They will be made from high carbon chromium stainless with optimum hardness after heat treat. Tested...
