Thread: New Motor!

sr16 long block with sr20ve crank, before i had sr20 de crank.
replaced a manley rod and new calico coated bearings
motor was cleaned out , new head gasket
my car is back on the road!



what is the best oil to use to break in a motor? and how many miles do i have to drive to break in the motor? when do i have to change the oil again?


thanks

this an all new motor or just a rod, crank and bearings?
on an all new motor i've always heard a straight weight oil is best. in a warm climate maybe like a -30w? definitely NOT a synthetic or blend. there is so little friction, it'd take forever to break in. i'm gonna do the 1st change @ ~500 miles or less. then again @ ~1.5k miles.

just use some regular conventional oil for the first break in.

yea new motor it got cleaned out the head and long block by the machine shop. i changed a new manley rod and new set of bearings, i put in pennoil 10w 30.

sounds like my setup, SR16 block with 8cw crank, forged rods and SR16 pistons just notched for the oil squirters. I'm about to switch over to full synthetic oil.

Who put together the motor ; ) ?

Stratton.
