CM 871 Fuel in the oil

[Waterloo]

Did you do the in frame yourself or did a shop do it? When we tore my motor apart in Rawze's driveway, besides finding all of the wrong internal parts installed... CM2350 450hp in frame kit, injectors and cams installed in my 600hp CM-871...

We also found parts that were about to fail, like the scissor gear on the injector cam, that was ready to blow apart. Also the injector cam plate, a one time use item that installs on the end of the injector cam was also reused, they can fail and come apart. Lonestar10 had the same plate reused on his fresh in frame to... He is in Rawze's driveway right now.

We also suspected the motor was dry started, as the lower end bearings looked like they had two million miles on them, not the 70,000 miles they actually had. And when I was under there undoing the caps for the bearings, they sure did not feel like they had the proper torque on them, they came out pretty easy.

Wrist pins too, quite a few reports of those failing or installed improperly.

Another thing, when installing the pistons, were the rings stepped, the gaps in the rings, some shops have been know not to stagger those gaps, and all of the fuel goes into your oil.

And the liners, mine were not cut, the ledge in the block, even though they assured me the work was completed, it was not. Liners were just bouncing around in there, lucky the block was not damaged. .

And the head, did they install a new head, a new reman head, or even cleaned up your old head and reused? Check the part number on that head. That is getting to be pretty common too, installing the old head or a crap reman and they bill you for a new one.

Just a few things to look at...
