Engine break in process.

[DRUNK411]

I just looked throgh like 20 pages from searching and this is wat I need to know guys, I remember seeing a thread on it a while back. I am getting ready to start my ty after a full motor rebuild and turbo rebuild. I was wondering what oil to put in it for the first start up? I found the thread on how to prime the lines and stuff before starting it, just want to make sure I have the right fluids in there. Also what about anti freeze, should I go 50/50 mix and how much goes in the upper intercooler and how much in the radiation. Thanks

Run 10w30 dino oil. You can pour some heavier oil like 60wt on the rockers since it takes awhile for oil to get there.
Run it until it reaches operating temp, set the timing, watch for leaks. Dump the oil, put in a new filter & you're off.

I would run plain water (no antifreeze) until you've had a chance to sort things out. Less mess if you have leaks, and easier cleanup if you have to pull anything back apart. Coolant is up to $9/gal here.

No. Don't use synthetic for break-in... save it for when you change it out.

Cheap wal-mart oil, 5w30 or 10w 30... it's not going to be in there very long.

many engine builders say straight 30,that is what i used,here is what i did,started the new engine let it run for around 5 min just changing the throttle a little bit,drained the oil,gets all the lube etc out,filled it back up with straight 30 and drove it 100 miles drained it again.then drove it to 500 miles drained it again and filled with 15,50 mobil one.
