Hi, The more I read the more I get confused. Application is either steel or stainless steel studs (used for the exhaust manifold) mounted in an aluminium head. Or any bolt or screw mounted in an aluminium head. I need an anti seize to prevent bolts/studs from twisting off during disassembly...

Were direct injection engines manufactured by Toyota in the 1980s computer controlled??

Hi, As for the rotary injection pump used in for instance 4 cyl L and 2L engines: Does anyone have some values for maximum axial and radial play of the input shaft? My pump is leaking from the oil seal and has a small play. I need to know if the needs to be overhauled or if a new oil seal will...

Hi, Can somebody elaborate on the reliability/robustness of direct vs indirect Toyota diesel engines? Lucas

Hi, I recently installed a genuine original new old stock Toyota speedo cable, however it wobbles around 50 mph and becomes steady again at 70 mph. The speedo cable is factory lubricated and cannot be disassembled - it is not designed to be taken apart so you can properly lubricate the inside...

Hi, My vehicle has sunlight exposed rubber seals for all windows incl the windshield. Even though the vehicle is 35 years old, the seals still look OK without cracks but somewhat faded compared to new rubber. I am not looking for a solution for the door seals. I want to treat these window...

I was able to fix it. It was a loose connection on the printed circuit board where the gauge units are mounted by means of screws that also carry voltage/current.

Hi, I have a problem with water temperature gauge in my instrument cluster of my Toyota Hiace LH50. The car is from 1984 so I am very sure that all other Toyotas from the 1980's show the same system: The temperature sender/sensor is mounted close to the water outlet on the engine with only ONE...

I have some new information since I got help from my dad: 1. I put the regulating valve back into the pump. It had been thoroughly cleaned. 2. I let the engine run hot by idling for 1h and kept playing with it, also driving uphill in the driveway. I figured that the hot engine would warm up the...

There are mixed answers on the fuel return amount. I have to admit that I support the idea that the fuel return must be large, because: Lets say you are driving uphill in 1st gear even with a trailer. The fuel consumption must be enormous since the engine is working like mad. That could even...

If I make the temporary fuel supply with transparent hoses I notice that the fuel return is very very little - close to nothing. It is as if the fuel initially supplied by the priming pump is used used up by the injectors for a minute or so and then the supply pump starts struggling keeping up...

As stated previously (I think) there is almost no fuel coming out of the return pipe. I pulled the regulating valve out now. It is not clogged and it moves with the spring. However I noticed: It was stated somewhere that the supply pump delivers at 100 psi which is about 7 bars. So the pressure...

I already did that a few days ago. I even used a transparent hose to see whats going on. Still the same problem. Is there a chance that the pressure regulating valve just behind the inlet banjo is causing all the problems because it is stuck open and the supply pump therefore is basically...

I now installed a brand new genuine Toyota priming pump but to no avail. It becomes more and more apparent that: The injection pump struggles to suck in the fuel - whenever I manually prime when the engine is running, it becomes more stable and is much easier to flip the throttle (ie reach high...

I did another test with even more transparent hoses. I need to stress this was not while driving, but just in the driveway where the fuel consumption is low. 1. Transparent hose on the fuel return and directly into a transparent container. 2. Transparent hose between the injection pump and the...
