1hdt

Hey guys, Quick question about head gaskets specifically for 1hdt. Is it possible for a gasket to weep oil/coolant or both without affecting the fire ring or having any other issues? I’ve been getting a bit of oil residue and now dried coolant right at the back at number 6 but no issues with...

Hey guys need a new crank for my 1hdt and been looking around and a factory crank is 3k and 3 month wait but there is some cheaper aftermarket ones around for about 1k to 1.5k and here by the end of the month. Has any one have any experience with the cheaper options or just not worth the risk?

I am a bit confused by this and I'm curious is anyone has been in a similar situation: I have a 1993 HDJ80 with a 1HDT. Stock CT26 Turbo, Stock Tune, etc. I recently built and installed a front mount air-to-air intercooler in the hopes of lowering my EGTs on long hauls and mountain passes...

Just something that's been on my mind. I can't justify the expense of upgrading to a larger airbox like a radius fab etc(yet), so I've been doing a little research on how else to open it up. Saw mentions of an FJ80/LX450 airbox lid with the larger opening and thought I'd pair it with new 3"...

Hello guys, I am currently in Panama. I am sharing photo of my cars. They are both from same year, Turbo Diesel. I am a noob and and I do not know much about cars to be honest. Both cars come with double tank but the sub tank does not read. I have seen that at the back there is no relay. I...

A friend is rebuilding his 1HDT. I put a 2LTE piston rod beside his. Thought it was sort of neat. They both look super beefy. 1HDT left (dirty one), 2LTE right:

Hey guys, I am parting out my 1HDT that has 300k km on it, recently started losing coolant. The engine did not overheat and it only drove about 150-200 mi losing coolant but never got hot, so I checked the compression and 1-5 were 470 + PSI but cylinder 6 had none. I pulled the head and...

So for the longest time I've had issues with the dash lights blinking while driving I suspect it's the alt and not the plug simply based on mileage I'd read that a tercel alternator fits. But when I bought one, mines different. Mine was slightly larger and had an oval plug. From reading...

Is there any reason NOT to use Royal Purple Duralec SAE 15W-40 in a 1HDT?

I have a question about a FZJ80 series to 1HDT (1HZ or 1HDFT) diesel and manual transmission swap and how it relates to cruise control and TPS. I know on some early model manual transmission HDJ80s, the trucks did not have a throttle position sensor on the injection pump even though they had...

I am looking for a 1HDT crossover intake manifold. Looking to delete my aftermarket intercooler. Let me know if you have one around and can part with it. Thanks

Hi expert folks, I'm still working on rebuilding my 1993 LC80VX 1HD-T. I've just added a GTurbo green wheel and kept the factory air filter box. As Turbo inlet diameter is bigger than the original CT26, my plan to just renew the factory rubber pipe down not work. I've read some guys warm it in...

Hey fellas I have a 1992 1hdt 80 series that has a weird coolant leak near the harmonic Balancer just under the water pump. If I start it up get it hot take it for a drive and bring it back to sit it won’t leak it’s only after I let it get cold start it up for a couple of seconds it starts to...

Hello everyone, I wanted to ask if anyone has an extensive list or suggestions to a list for baselining an HDJ80? I'm mainly focusing on the mechanical side of things. Thank you in advance!

1991 HDJ81 Turbo Diesel located in Saint George, Utah. 390,000 KM. Just drove it to Texas and back (3k mile roadtrip). I’ve only had this truck since October, have given it some love since I bought it from another mud member. I go through rigs quick, but I’m trying to buy a house and need to get...

Hi folks, In my Toyota gasket kit 04111-17020 I have a ~78 mm aluminum crush gasket that has a mint green coating on either side. Its been a year since my 1HDT teardown and I don't recall encountering this part. Anybody know what it is for? Cheers

I am selling my 1991 HDJ81. I have owned this truck for nearly a year now, and I have put a lot of love to get it into the point it is today. I'll start by recognizing that this truck is not without it's faults, and my price is certainly negotiable, and I am not expecting to get asking price for...

So I had a leaky injector pump and went the route of having one shipped over by gturbo and a red wheel turbo while I’m at it. I pulled my old pump and reinstalled the new one along with timing it while I was at it. The first start up it ran rough! I figured I got one tooth off on the belt and...
