I have heard that Pontiac quad 4-motors 2.3 L 16 valve - is a risk/danger motor because it's oil pressure often after 150.000 km (94.000 miles) ar going to oscillate and then fall to zero and the motor crash/died with big damage. I hav hear that the gear wheel on the oilpump is made oc plastic material and thats cog are distroyed.
Is this thrue and what should be done for prevent this?
