I have heard that quad 4-motors 2.3 L 16 valve - is a risk/danger motor because it's oil pressure often are going to oscillate and then fall to zero and the motor crash/died with big damage. I have hear that the gear wheel on the oilpump is made oc plastic material and thats cog are distroyed. Or are there any other ground to this. What should be done for prevent this?
