Ahhhh hello all, I’m a 1988 FJ62, engine rebuilt a year ago, my 2 quick questions first:
1. Does anyone have a link to the FSM that includes the lubricant system?
2.Does anyone know the torque setting for the bolts on the connection rod near the top left of this image below.
Imgur: The most awesome images on the Internet
So long story short... I’m being plagued with low oil pressure. Truck starts fine. No smoke/blue smoke. Sounds and performs well. When the truck starts the oil pressure gauge waits, then pops to the bottom of the acceptable range. Over the next 10minutes(give or take and depending on how much red light idling I do) the oil pressure slowly drops to basically below the very last indicator line on the gauge. I would be below the red if it was a fuel gauge for reference.
It then more or less stays there until the truck turns off and the gauge drops entirely.
I have:
-checked with a full screw in mechanic oil pressure gauge (same result)
-oil changes with much heavier oil.
-replaced pressure sending unit
-replaced the oil pump.
Thoughts?
Many thanks.
