Hi, The engine sits in a Coaster, so a pita to get it out. Also no hoist/ramp available. Thus try to avoid taking the sump out.

Hi all, recently my 1HZ started to leak oil from the sump plug such that I had to put a bin underneath (probably about 50ml per day). Having experienced a decrease in resistance when tightening the sump plug during recent oil changes, I took out the plug and drained the oil. Then I saw...

Hi, thanks for putting some thoughts in. In fact the figure "1 liter on 1500 km" comes from having used only 15W-40 so far. For the next oil change I had already on the agenda what you suggested as well ...... going to 20W-50.

Hi all. My 1HZ (no turbo, sits in a toyota coaster bus with 3.2t tare weight) as approx 500,000 km and got recently a rebuild injection pump. I have no clue about the injectors age. It starts at say zero degree celsius ok (with 3 glow plugs broken), with repaired glow plugs without any...

That's what I thought. For the Aussies. What price can I expect for a rebuild (either mine or exchange). Currently, I have only two types of offers, one from here: Reconditioned Diesel Fuel Pumps » Diesel Center AU$1350 for exchange, one from a local branch of this Diesel Care | Excellence in...

Hm that makes me worring. However, it is not the pump shaft which has play, and when the pump was on the play was between 0.5 and 1 mm, visible as a small gap between the pump flange and the gear housing. I assume that such play is necessary to adjust the timing after the shaft nut has been...

Hi Loober, thanks for the comment. I did not forget to loosen any bolts. I checked it several times before applying force. What means "SOL" (sorry I am not native english. "Sadly out of luck"??). Here is a small move about loose timing gear.

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...

Here are the pictures of the pre-heating timer. I found the other relay. I could also trigger it. I found the wire from the timer which is running it. By putting voltage on that wire the relay switched and I had 22.8 volt at the plugs. I also measured how long the timer puts voltage on the...

I tought about "independent" glowing, but the 1hz manual states that I shouldn't apply more that 22v to the plugs. The voltage at the resistor is +24 volt. Circumventing it I would apply 2 volt more than allowed. I affraid of causing at plug melt down in the cylinder.

Update. I was just at the local toyota dealer and the confirmed the part number using the vin number of my bus. I have now odered the same part via toyota for 238AUD (instead of 100USD from Abu Dabi). However, the mystery around the voltage at the glow plugs remains. Does anyone has an idea...

Thanks. I have posted the question there as well.

Hi there, I am new to Toyota and acutally dont have a Landcruiser. My current toy is a 1993 Toyota Coaster, which at that time was manufactured with a 1HZ engine without turbo and a 24 volt system. I hope there a some people here who have experience with this engine. My current problem is the...
