Breaking in newly overhauled L134....

Gentlemen:
Is there any special protocol I should follow to break in a newly over-hauled L-134 "Go Devil" engine? Engine has been sitting about 8 years. I think we might get 'er fired up next weekend. Any particular lubricant I should be using for engine oil (dino vs. synthetic, for example).
Thanks,
Jordan

Go to your copy of TM 9-8012 Operation and Organizational Maintenance and read pages 18 thru 20 very carefully.

I will give you a little slack. Use mineral oil for the breakin period. A straight weight appropriate for the ambient area temps. That chart is on page 54!

Wes,
What about adding ZDDP zinc additive?
Or using the Shell Rotella T that has plenty?

The break-in period uses straight mineral so actual break-in wear will take place. Once the 500 mile break-in period is complete then more modern oils that still retain adequate levels of the ZDDP additive are great for insuring good long term lubrication. Shell Rotunda is a great oil for normal use of the jeeps.

Jordan, if you haven't already it's recommended to prime the
oil pump before starting.
