I have two failures. Both due to oil starvation. 1st one the oil pump disintegrated second a small piece of what appeared to be black Bakelite type plastic blocked a piston cooling jet. I personally rebuilt after each failure without having the block machined just rehoned at home.the failures were over 25k miles apart so am assuming unrelated I have access to proper measuring equipment and all was still in tolerances. This shows how some parts/systems are weak but others are more resilient.
Lessons learned
1. Change the oil pump from the variable veined type to the geared type to avoid this type of failure and then at 50 60 k intervals
2. Replace oil pick up plastic tube with new anytime the sump is off to avoid the second type of failure as this is where i suspect the plastic came from

Hi Siwynne,

Can you explain more please, especially on point 1. Any photos or part numbers?
