Ok guys as some of you know I just recently did a little "sprucing" up to an old 440 I picked up. I replaced the camshaft and lifters(only internal upgrade) so now my question is on the break-in procedure.
I have already purchased some Lucas break-in additive but I'm not to sure what oil to go with as far as weight just for break-in.
How long should I run the engine on the break-in oil? Just during break-in process or 500,1000, etc...?
After break-in process what brand and weight oil would you recommend? I know the whole point of the additive is the zinc so what are your thoughts on running diesel engine oil which is high in zinc? Keep in mind the engine will have headers to purple hornies for exhaust so no cat or mufflers to clog up. Also I read that using the break-in additive in future oil changes prolongs the life of the cam and liters. Is this factual?
Now as for the break-in procedure in general I read somewhere that immediately after start up take the engine to somewhere between 2000-2500 RPMs, tho I dont remember for how long or how many times nor the cooling down procedure.
Any helpful info will be greatly appreciated. Thanks
