Hey folks,
First time posting but used this forum countless times during my swap...thanks for the help.
1986 Toyota 4Runner with a 1985 om617.952 swap.
I’ll cut to the chase. Swap is done, but I’m having overheating and white exhaust smoke issues. White smoke at start which gradually decreases as motor warms up. Idles fine for as long as I want with no cooling issues. However inclines are a huge issue at low and high speeds, white smoke gets bad and engine will rapidly start to heat up. I always lay off before it gets out of control. Smoke gets bad before the engine temp ever gets to 200*f
Overheating issues aside, the white smoke concerns me the most. All the research I’ve done seems to point to a head gasket but there is no noticeable oil in the coolant or milkshake in the oil pan. Again, I’m not as concerned about the overheating since if it is a simple cooling issue I will upgrade the radiator and fan. I’m more worried that the overheating is a product of a head gasket problem.
I’m admittedly not very well versed in diesel motors, so I am wondering what sort of things I can do to narrow down the problem. I love this truck but this has been an absolute nightmare. Basically a paper weight right now since I don’t want to get stranded in the woods with no cell service.
Any suggestions would be greatly appreciated.
