Don’t Break It! Engine Break-in Tips for Initial Startup

[@badstimpy]

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 !!!

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

Sick intro

[@supriadiramlan5545]

nice video, hopefully more people doing break in right

[@SummitRacing]

Thanks for watching !

The man touched on every area.

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

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

[@pingpong9656]

Why fill half way on the oil filter?

[@GAMINGOBRIEN69]

You dident actually start it

[@maddpeanut6313]

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.

[@Jonhobbs64]

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.

[@joey9511]

Yeah thats also why those same car manufacturers say burning a quart of oil every 1k miles is within spec 😂

[@ParlayyBrayy]

How many miles do it take?

[@tmisener20]

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

[@67cudaksa34]

make sure the timing is spot on.
