I'm swapping a 1KZ-TE into my 84 XtraCab Pickup. I have spent a lot of time getting the new motor mounts dialed in for an ideal engine position.
I used new OEM 3VZE rubber isolators for mock-up. Unfortunately, with the weight of the power train set down, the rubber deform enough that I lost 1/2 of motor height. I can raise the frame side mountings to get that back easy enough but am more concerned about the position of the mounts under the weight. It seems like the "cups" that prevent excessive movement of the motor under heavy load or engine braking are resting on the limits..... I hope that makes sense. Seems to me the motor is sitting on the mount with only a thin rubber overmold instead of being fully isolated by the block of rubber.
I'm considering buying some OEM mounts for the Toyota Prado (where this engine came from) hoping they'll be a firmer durometer.
Does anybody have any insight if there are differences other than part numbers?
Also worth noting, the original cast iron mounts comingnoff the engine have a 35* angle, I stayed with the 35* angle on my fabbed replacements. This angle is pretty steep compared to the 22RE or 3VZE angle. This is increasing the distortion of the rubber isolator.
Poly is not an option due to diesel vibrations I think.
Thanks
