Engine Break in Run in... Who knows!

I would also add mufflers hooked up. You need to be able to hear if there's a problem inside the engine.

 

Thats a good Question? I would think if you have been turning it by hand you would have wiped all that "CAM SNOT" (lube) off by now...

 

I haven't touched it in at least 3 years.

Great thread. I am gettin ready to fire my 223 for the first time on a fresh rebuild so this is coming up at a perfect time.

 

I would probably drop the sump and take a peek inside, it can't hurt. (cost of a gasket), check for condensation maybe. I think it would probably just be me being over cautious but where I am at there is plenty of moisture in the air...who knows maybe a RAT moved in....

 

And if you cant get your rings to seat, mix some of this with some gasoline and pour down the carb. It does work too!

Catapillar uses somthing similar on their diesels to get the rings to seat.

 

G,day mate I presume you have left out the dissy and spun up the oil pump with a shaft on a power drill to get oil pressure.

 

Allways do, lets me find any leaks or bungs I have left out, once I had a stream shoot clear across the back yard from a split in a copper sender line!

 

#### Bingo !! I'm just not a fan of the 20 min high RPM thing with no load on the engine. 20 mins of free-wheeling the engine with no load will not be good as I have seen this glaze the rings and make them tough to seat. In the perfect world of a dyno you could monitor and load the engine easily but we all don't have access to a dyno. I usually prime everything including the carb. Set the distributor so the engine will fire right off. I fire the engine check for leaks,set ignition timing. Now this process takes about 5 minutes. Shut the engine down. Tighten the intake and the exhaust as they will both loosen up. Re-check for leaks, slam the hood and head to the highway so I can put a load on the engine and keep the rpm up for the cam break-in. I have used this method for years and it has never let me down. I hope this helps >>>>.

 

****** hell just power drilled the oil pump and OIL ALL OVER THE SHOP. Looks like the filter I am using had wrong part number! the seal was incorrect diameter. Talk about luck I spun the oil pump with the drill, got to 15 PSI and Blamo! HAHA I can laugh now now I have mopped up....

^^ This worked for me. Careful lube. Wynns concentrate. 60 freeway miles ( late at night) at 80+mph. 70,000 miles later still tight.
