1. Q What oil should I use and what about the zinc reduction in modern motor oils?
A If engine is clean on the inside it is highly recommended to use a multi grade motor oil such as 10w30 or 5w30. Yes we all have learned that the modern motor has greatly reduced zinc a anti wear additive. This anti wear additive was required when the automotive industry switched from steel cam shafts to a cast iron camshafts. The Model "T" "A" and early "V8" Fords had steel camshafts and this problem of premature camshaft lobe wear has not happened. We also have lower valve spring tensions and lower RPM's that prevent this wear from happening. Later V8 fords had a cast iron camshaft and a different oil or zinc additive should be used.
2. Q Are our engines rebuilt for no lead gas.
A. Yes all of our engines have ss straight stem valves with one piece valve guides. We install nickel chrome hard valve seats in all of our engines. This makes the engine compatible for no lead gas by industries standards. Note that all the scare from no lead gas did not happen and there is no reason to dissemble a good running engine to make these modifications. Nor is it necessary to use an additive to prevent this problem that wont happen.
3. Q Do our engine have a contact seal or modern seal.
A. No our engines use the deflector and slinger system as the original with no rear main leaks. Our tolerances are right on using only larger oil pipes on the rear main cap. Note we seal cap to block and we use sealer on the rear main fasteners. If you have a rear main leak visit our page.
