[QUOTE=joespanova;499472]So I started pulling the engine down , pulled pan and its full of bearing material. One by one the rod bearings looked like they were getting restricted oil flow but not as bad as I 've seen. The rods looked fine.
The main bearings on the other hand WERE COMPLETELY DESTROYED
, to the point of the 3 center main caps getting "blued or blackened" .
As you can imagine I'm angry , pissed and any other verb you can come up with.
This isn't my first small block , to say the least...............but it IS my first Dart block ( Little M sportsman ).
The main caps no longer fit tight in the registers either, BTW.
Now here's the really pathetic part.........THESE BLOCKS ARE SUPPOSED TO BE PRIORITY MAIN OILING? WTH is going on here?
Main clearance at .003 , crank is straight ( BRC crank ) new Melling pump etc etc. The plugs in the block at rear are not plugging any passages...not that I'm aware of. The sump had 6 quarts.
Now how in the he*lL can a priority main oiling block starve the mains?
You can bet I'll be calling Dart in the AM.[/QUO
its definatley lack of oil.Severe windage or you are pumping all the oil upstairs..I resonded to your issue on another forum.When you get it repaired,if your still using the same cam and lifters,put a drill on the pump and see if your getting excessive oil to the top,starving things down below.restrictors may be order.Seen this movie plenty times before.Not the blocks fault.
