When breaking in a flat tappet cam , use a weaker valve spring + spray some graphite to cam lobes ( helps camshaft assembly lube grip). DONT use zinc additive - use dedicated high zinc break in oil . draw a line on pushrods to make sure they are spinning . If possible , use DLC coated lifters . Also make sure you have pre lubed engine before startup and have correct length pushrods. Now cross your fingers !!!

The man touched on every area.

nice video, hopefully more people doing break in right

Thanks for watching !

I pull a plug or temp sensor out of the top of the manifold when filling so I know engine is full.

Sick intro

make sure the timing is spot on.

Why fill half way on the oil filter?

AMSOIL has synthetic break-in oil so no more dyno oil in an engine that you dont want dyno at any point.

How many miles do it take?

Covered in the fist couple min....change oil at 50miles 500 miles...1500 miles and can go to synthetic at 4500 miles

The myth of synthetic oil not allowing rings to seat has been debunked for decades. Brand new engines use synthetic oil directly from the manufacturer.

Not true! Cast iron rings with a rough hone that older engines used to use might not ever seat. New cars have been using low tension , stainless steel rings with a very fine hone. Do reasherch before you cause someone to ruin there engine. You're welcome.

You should make a bigger deal about using an actual break-in oil. You did say it about 3/4 of the way through the video, but in the beginning, all you said was oil with high zinc; you didn't say break-in. You really should put a text over the video, in the beginning, to say to use a "break-in" oil. It should be an oil with high zinc (ZDDP), low Molybdium, high detergent (to trap all the metal particles), and low anti-wear additives. And perhaps mention it may not be easy to find at a local auto parts store since these aren't API certified

You dident actually start it
