Re: Oil Problem (Windsor 302)
if theres no oil leaks, theres only 2 ways to loose oil. rings or valve stem seals.. 150,000mile and your car is a 71 model.. valve stem seals at a minimum are just a seal and i dont think are designed to last that long if its original.. same goes for lifters.. the lifters either arent holding oil pressure, or your oil pump is not pumping enough oil press.. and could be oil thats thinned out.. when was the last service?. first things first get out your compression tester.. as a rough guide on a dry compression 120psi at bare min and i would expect at that to burn some oil.. good compression about 150-160psi. anything about 100psi and its time for a rebuild. if you then want to check for valve seating 3 squirts of engine oil in the plug hole will seal the piston and check for compression leakage in the head and gasket. make sure accel at WOT when cranking and about 5 cranks i think is the correct ammount. all spark plugs out for cranking speed.
