break in oil?

Post by samsvan on Mon Dec 21, 2015 6:14 pm

Gentlemen,
It's time so I wanted to see what you guys think about weather or not I should use break in oil. It's a fresh rebuilt TBI 350 with an RV cam. Is this something you only need to worry about on race motors?

Fresh bore or just honed? Chrom moly rings or plain cast iron type? I have done both ,both ways. Chromolys seem to take forever on regular oil to seat in. Old school was running 20wt non detergent for awhile and I have done that but long ago with plain old hastings rings. Memory tells me that works quicker. Quickie overhaul I did last on my 350 I went with synthetic right away and it took all season to quit going thru oil a bit quick but finally seemed to set in ok. Curious what the other think also.

You should always use a bottle of break in oil on all hydraulic lifter motors and a 4oz bottle of ZDD zink additive change the oil (10W30) with in 1000 miles.... On roller cam ones it is not necessary to use the break in oil but "Never" run synthetic oil on a fresh motor as it will take a long time for the rings and lifters to seat in properly.....Then after that I use a 4 oz bottle of "ZDD Plus" zink additive every oil change after that...!!!... Smile ..I have never had a problem useing this method...The "Break In" oil is used mainly for the cam shaft...

Thanks everyone. I went on the ZDD Plus website and they explain why it's necessary to use this stuff in older motors and it all makes perfect sense. So once I put this in, how long 'till I can do some donuts?bounce

Digz, the video won't load and Matt, just kidding about the donuts! I had to order the ZDD Plus online so I'll have to wait 'till after the weekend to do the break in. When we get past that, I'm taking it to get the exhaust and Line x on the interior done. Paint after that and then the interior. Thanks again for the input and Merry Christmas to all you guys!

50 different builders will have at least 50 different answers, so let's first agree on some basics:

Make sure you use a GREAT filter to catch all the junk!
Use an additive for flat tappet cams.
Synthetics are often too 'slippery' to allow ring seating.
Only run the break-in oil for a short time. That first change removes all the fine particles that come loose and are worn from surfaces. Also change it 'hot'. Don't let it sit overnight before changing.

Some prefer taking it easy for the first 500-100 miles, others prefer running it as hard as normal operation. If the rings and cylinder bores are compatible, it should take anywhere from 5 minutes (moly) to 500-1000 miles (cast iron) for the rings to 'seat'.

It is very important to have the engine adjusted as much as possible to be ready to run on initial start up. You do NOT want to have to start, stop, start, stop, during the critical first half hour. Timing, carb, valvetrain, belts should all be ready to go. You must have a good cooling system (they tend to run hot at first) and the starting system must be able to crank over a fresh engine. Have a fire extinguisher handy and a second set of eyes if possible. If you are doing this without a drive, have a big fan for the radiator, extra fluids, easy access (doghouse open or removed), tools, a clean, flat surface to be able to spot any leaks and it would be smart to have the rear wheels off the ground (jackstands!) so you don't worry about the transmission. While a fresh engine sounds great with open exhaust (if everything is adjusted right they like to start quickly, rev fast and shut off immediately), it's better to have a quiet exhaust so you can hear any strange noises. Most header makers will NOT warranty coatings if used to break in a fresh engine. So you may have to use some used headers or manifolds for the break in, then switch to your nice new headers.
