Allis 7045 Piston blow
Hi,
A couple of days ago, started up my 7045, ran for a few minutes and suddenly it started blowing white smoke from the blow-by pipe. I immediately stopped the engine. I noticed a knocking noise and the engine was rough running. I suspected something wrong in the crankcase, so I decided to drop the oil pan to discover that #1 piston had a hole in it. I attached pictures of the blew piston hopping you could help me find the cause of this blow since the other pistons are in good shape. Everything is stock except for the injection pump, the Roosa Master was replaced for a Bosch MW.
Thanks

IMHO it looks like a bad injector/injector tip, although I am no expert.
