steelzeus,
have you been having an oil loss problem? how long have you had your vx? i have come close to running low on oil. which i contribute to the pcv valve. i have lost 1 1/2 quarts of oil and changed the pcv valve and the oil loss stopped. this has happened more than once. if someone has run the oil too low once they would have damaged the bearings. a high volume oil pump does not help in this situation. also if you have a rod knocking you will more than likely need your crankshaft machined or replaced. i will be replacing the pcv valve with a breather and will monitor for oil loss to be 100% sure that the pcv valve is the problem. shawn
