Engine break in and supplies (questions)
 

Well, im just about ready to break in my motor on the stand, And would like to here some opinons for break in methods aswell as what oil to use.
I have the understanding that a non- synthetic oil is recomended for engine break in... but what brand and weight of oil should i go with eh?.

My motor is a 1914cc type-1, the temps that i will incounter are in the low 30s to low 50's.
After break in i would like to run a full sythetic, how many hours/ miles is recomend till i make the swap from dino oil to synthetic? (I have never done a engine break in, or had much experiece with almost new cars)

Thanks,
Jonathan

you MUST run a dino-based oil for at least the first 5K miles to make sure that the rings seat correctly. On initial startup with those temps I would run a good quality NON-SYNTHETIC 10w-30. When I got my new motor, the builder (who is highly respected in the area) reccomended that on initial startup to run the motor between 2-3K RPM for 20 minutes to break in the cam and lifters. He also advised to allow a 5 minute warm up every time i drove the car for the first 5K miles.
Before Startup:
- I would reccomend a valvoline or Shell Rotella type oil.
- Try and set the timing before fire up, (~30deg @full advance/ ~7deg. BTDC static)
- remember to adjust the valves before startup (if the builder didn't)
@ 500 miles
- Re-torque the heads, and change the oil (check for abnormal shavings in oil), Re-adjust valves.

Also, keep in mind that a fresh motor may run hotter until it is fully broken in.
