I've checked the oil, drained and refilled, and no contamination of the oil. I am inclined to attribute the coolant loss to a poor job of bypassing the turbo as the coolant loss only began after the turbo was bypassed. Unfortunately, I'm depending on a shop to do the work because I have...

At this point, the oil cooler and oil cooler cover have been replace, the head resurfaces and a new Toyota head gasket installed and the turbo coolant lines have been bypassed. Made several round trips to town (1 hour each way) and a 100 mile trip through the mountains (4 hours) with only tiny...

The coolant lines have been bypassed. I'm not too worried about running without coolant to the turbo as turbos ran for years without coolant. Wherever the leak is, it it very small as it took several days of driving before any oil was evident in the coolant reservoir tank. After one day with...

Hi Dougal. I believe that the machine shop pressure tested the oil passages in the head to see if any air leaked into the coolant passages but anything is possible. The Prado is back at the shop and I will wait till they respond. I've passed on all the suggestions from this forum.

Good idea. For many years turbos ran with only oil so that might work.

Manual transmission so no oil cooler in the radiator. I was also thinking turbocharger as it has high pressure oil and coolant running to it. How to verify without replacing it?

Update: Both the oil cooler cover and the oil cooler plate heat exchanger were replaced. The head was removed, gasket surface was resurfaced and the head tested for leaks - none found. All new gaskets were used including genuine Toyota head gasket. Still the problem persists. Any suggestions?

Title says it all. Price and photos would be good. I'm located in Ann Arbor MI, but don't expect to find on locally. Let me know what you have. Thanks.

Thanks Rick and dogfish for your input. I will scrap the idea of dropping a 1HD-FT in my Troopy. I may have a line on a 12HT with H55 transmission attached.

The HJ45 Troopy that I have here in Costa Rica just doesn't have the grunt to effectively climb the mountainous roads where we live. It is embarrassing to head up a train of 20 cars as I slowly crawl my way up the winding roads in 1st gear. Also, a lot of parts for the H motor are no longer...

Unfortunately, I did not have the tools available to perform the work myself so had to rely on a highly regarded mechanic. I could not find a leak in the removed oil cooler but then I had no means to pressure test it. I just filled it with gasoline and let it set. No gasoline leaked out. I...

I have a 2003 Prado with a 1KZTE diesel and manual transmission. I find oil in the overflow reservoir floating on the coolant. I changed the oil and filter and there was no sign of coolant in the oil. I had the oil cooler replaced but not the oil cooler cover. Problem persists. Engine runs...

Got it! Thanks for the info. Same for the 3FE bell housing I assume?

I want to hang the A442 automatic transmission from a 1994 FZJ on a 1HD-FT diesel. Does anyone know if it will bolt right up?

The weight for the engine with engine wiring harness, starter, alternator, power steering pump, air pump, fan and flex plate is 629 lbs. Add in the air cleaner with air flow sensor, ignition coil with igniter and air pump silencer and the weight comes to 649 lbs. These are actual weights...
