oil pump problems!!
ha sanyone seen a oil pump(M55) break off? It broke by the dail pin holes, the pump, screen, and oil pump rod was in the bottom of oil pan when I pulled it off. the top part of the oil pump was still attached to the block. It never made any noise, just noticed I had no oil pressure, and turned the engine off.Just wanting to know if anyone has had this happen or maybe what caused it. what it be good to go with a M55hv?

Melling has been having a lot of problems with their pumps breaking off. I believe you have to go with the select pumps for the good castings. They changed the std. casting to save money I guess. Go over to speedtalk.com and do a search about it. Lots of info on them.

A friend of mine had a m55hv pump do the exact same thing. loaded it in the trailer ready to go and unladed the next week with 0 pounds of oil pressure..
Melling is just going down the crapper from what I have heard... |
Thanks for the replys. Just bought a new m55hv and gonna bring it back tomorrow.

Hey..Thanks Todd I have had that problem.. :oops:
I kept replacing the pumps with the older thicker casting pumps and even a BBC HV oil pump it help up until the crankshaft twisted in Half. I believe what was happening was the crankshaft was cracked and causing a vibration in the motor.. It was a Cast steel crankshaft. Since then I have swapped to their recommended pump.. http://data.melling.com/Select/small_block_chevy.php And upgraded to a 4340 crankshaft. I think I put the cast one thru more than it's share of abuse and it failed it breaking off the oil pump was a sign and I didn't want to think that. If it was mine I would have the crankshaft magged and get one of these pumps. I use the 10552's. |
