1hz

Hey guys, Just wondering if anyone knows the part number for ARP headstuds or where i can get headstuds for a 1hz. Going to be running 30psi plus and want the head to stay on. Thanks!

Took my 1hz's old Genie headers off yesterday - they have a fair number of weld cracks and pinholes due to rust/age/vibration/etc. all of which couldn't be seen without removing them. To be honest, they are pretty ugly and one of the weld cracks was 1/2 way around at a join where three cylinder...

Has anyone had much luck making decent power out of there 1hz wagons? I have a 12mm pump and currently have a turbo on the way and wondering what sort of power people are making at what boost and afr. Any help will be appreciated.

Many of you probably know me, but I thought I’d start a thread to doc my workings. Bought my Troopy in Honduras last year when we were living there and drove it back to Texas when we came back. I have lots of plans and they will happen very slowly. Lol. I’ll update what I’ve done little by...

Since replacing engine mounts I've noticed the motor is idling rough as though it seems to randomly 'missfire' an injector. I've replaced the fuel filter (as I had a new genuine one), so I'm fairly sure there's no air leak into the fuel system at the filter area. I'm wondering if it's possible...

Hi there, just want to share my experience (as a warning) from pulling a pump out of a 1993 Toyota 1HZ engine. I was probably the first pulling the pump from that engine. Except the special service tool, which I replaced by a home brew puller, I followed the manual. The puller was made from...

Hi there, the pump on my 1HZ engine (1993) is leaking. It appears that the diesel is dripping fro the left hand side time cover, thus accessible without taking the pump out. I have had a look into manual and suspect that the two o-rings behind the timer cover are worn out. I have the o-ring...

Hi guys, I am currently rebuilding my 1HDT motor and my camshaft had a bad wear (water or bad lubrication maybe), I decided to buy a used camshaft and then found that it had a light wear as well: My mechanic said its better to not take the risk. So I decided to get my money back and start...

I've wanted a 60 series for a while now. I really dig the round headlights and the overall look of them. Recently, my buddy Heath offered to sell me his 1987 FJ60. It has a lift, 33's, front ARB bumper, roof rack and an H55F tranny. The bad part is that the engine has a bad rod knock and the...

SOLD Well.....:bang:. I am FAR from happy about this. This is my ultimate dream vehicle and I searched very hard to find it. I built it up the way I wanted and now unfortunately work has been slow so I need the funds to pay for the boring stuff in life. Vehicle info: 1991 HZJ75RV Troop...

Hi, First off. I'm new to this. Please tell me if I'm doing this wrong! There is sure to be many posts after this one! My partners the "mechanic" & I'm the "researcher" Just replaced the clutch in our 75 Series. 1HZ. My partner says when stopped at a red light - the car wants to go forward...

**** SOLD **** Selling my 1990 Toyota Land Cruiser (HZJ73). Clean and clear California title in hand. If you are familiar with these trucks you know how difficult it is to get them registered in California. This truck is smog exempt, so it will never need a smog check. The truck has...

Hello hello from Switzerland, I just got this beautiful troopy HZJ75 from 1999 with 200'000km on a 1HZ engine 4.2 D without a turbo. My problem : I have this kind of subtle hiccup power loss that becomes very distinct just around the happy cruising rpm zone. The only way to drive is by going...

Hi guys i have currently got a 1997 1hz turbo diesel landcruiser and for the life of me i cant find the TPS cable??? (throttle position sensor) does it even have one? Installing a turbosmart blow off valve and need to wire the BOV controller and solenoid to the TPS as there is obviously no...

1HZ diesel engine valve shim job. I have a genuine Toyota tool for it (thanks to another 1h8mud forum member), have read up quite a few guides on doing it. My 1hz now has 630 k km's on it. Cannot currently afford to replace motor with a rebuilt 1hz or 1hz+t or 1hdt and fuel usage is going up...

As the tile says.... Just got the ip back from the shop, installed it and on the test drive as I was caging from 2nd to 3rd uphill the engine went crazy and tons of smoke at the back... Then after 3 4 seconds it goes back to normal. Car drives fine af lower rpm but if revved up to change gear...

So, i have two trucks both with perfectly good running engines. #1: 1PZ Diesel, turboed about 6 years ago, rarely gets driven. EGTs always kept below 1000. Just had the valves adjusted and fuel pump tweaked. about 160K KILOMETERS on it (100K miles), - 1991 1PZ, 3.48L - 5 Cyl diesel - New...

I figured it was time to go ahead and start a build thread since we are getting close to commencement. I've been using Rob Smith in Georgia for all my cruiser needs the last few years. A few months ago he talked me into acquiring a 1HZ to install in my FJ62. Found a solid motor, pulled the...

Good day All, I am having oil leakage problems on my 1hz engine. See attached photos shows leaking from the driver's side of the engine block from the rocker cover down to the drip pan side. I am not sure if it's my head gasket leaking/rocker cover or the connection to the exhaust manifolds...
