Camshaft Break-in

[BigDave]

I recently had some new Crower 403's put in my Integra and have a few questions about break-in period.

First I have synthetic oil in my car now. It wasn't until after the cams were installed that I read that you should not use Synthetic oil during the break-in period. Will this damage the cams if I continue to use synthetic oil? Should I do an oil change and put regular petroleum based oil in my car now? It currently has about 22 miles on the new cams. Can I change from synthetic to petroluem based oil?

Any help is appreciated

Switch to non-detergent dino oil for the first 1000 miles or so
Let the car idle for 20 minutes
Don't drive real hard
Adjust valves

I beleive that the non-synthetic oil thing is only for breaking in of rings, as the synthenic oil molecules don't allow for a good "bite" into the cylinder walls by the rings. I think you should be ok for your cams.

yes, there is no break in for cams. install them, set the lash, and have fun.

Crower suggest that the cams be broke in with regualr oil. I just don't know if it will damage anything if I run synthetic. I think tomorrow I will just do an oil change and run regular oil for about 500-1k and then change back to synthetic.

install, set lash, idle for 10-20 min, drive around for about 400 miles, let engine cool, set valve-lash again, check for abnormal wear on camshaft, bearings, and rocker assembly, maybe swap oil if you want, then.......let it rip!!!!

i believe that's how you're supposed to do it. what do i know i only have a 12 sec all motor sohc











hahaha j/k.
