compare the cost of the products used and the failure hassel to 6 quarts of amsoil 30 weight brake in oil .


never a failure and run it for first 1000 miles before change in all engines i build .















No he used the Lucas additive, not their oil. I fail to see how using a semi-syn oil with the ZDDP additive could have caused this. Since 14 of the lifters are fine I don't see how the oil was the problem.
