1hz

This is the AC high-temp thermoswitch that fits to my 80's 1hz motor. The AC has never worked since I got the 80 in 2011. I replaced this switch a while back as the original one has been damaged. Wiring harness to it is also damaged and has no mating connector. Can anyone tell me what the...

My existing starter motor (a Bosch) fitted to my 1hz motor is beginning to play up. I suspect it's the solenoid contacts or something related to that, similar to what happens with the higher quality genuine Denso starters. I'm thinking of buying a new genuine Denso starter and 'going back' to...

Hi All, Is it worth to install this to BJ70? Sandwich 24mm JACKMASTER - allow use of Oil Pressure Accumulator on Toyota etc | eBay I want to install the oil pressure gauge and oil temp sensor! This adapter seems it is easy to do for DIY! :) Cheers, Eric

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...
