Found The Problem!! Grrrrrrrr

[berkes454]

ok..........most of you dont know that i blew the motor in my monte (shhh.....its a secret) and i couldnt figure out why...all i knew was i lost oil pressure and she quit.

Yesterday i began to tear her down and today i got down to the bottom end and when i droped the oil pan i noticed something sitting in the bottom and the pick up screen from the oil pump WAS GONE!!

Well i pick the funny looking object out of the pan and looked at it..and it looked like the pick-up screen got jarred loose and the crankshaft mauled the hell out of it.

Can someone tell me what happend to my damn engine??? and how the hell this happened??

Wow, that sucks.
It sounds as if you mean the pick up tube. The screen is just the little mesh thing right at the bottom. Losing that will not produce a lack of oil pressure.
Some engine builders do braze the pick up tube in place. Otherwise they are just a press fit and can loosen up, fall out or start swinging around in high G manoevers, especially if the oil is sloshing around in the pan. By the sound of it, yes, it did get loose and was clipped by a crank throw.

I also use a permatex adhesive sealant on those tubes when I redo Mercruiser (Boat) Engines for exactly the reasons Rat just stated. As you found out, they really do better when they stay put. Good luck on the rebuild.
