G Day all, Whats the opinions on using a zinc break in oil on a new motor? Some say no ....dont need it. Some say yes a must. No synthic oil. Any thing helpful on a new cam and lifters? Thanks
I would say no. It wouldnt hurt it but doesnt really “need” it. The rings are already seated and the roller cam/lifters dont need to establish any “wear patterns”.I have an engine that had built and put around 2500 miles on it. Pulled it from my truck and went with a 5.3 LS engine in the truck. The engine is going in my 64 Nova. The short block remains the same but with a roller cam. New heads and a different intake. Is break in oil needed for the roller cam in this case.?
