Glad to hear that you found the root of the problem

! Sorry to hear that it was something so *simple*

. I hope that the manufacturer does SOMETHING for you since it was SO important to them to save a few cents per casting to better the bottom line

Re: Pulled engine today and found... (pics)

One of my back issues of Hot Rod actually has a letter from Ed Hess published in it talking about the oil pump failure. According to Melling, the newer pumps were made with thinner casting walls to save a buck so their parts stay cheaper. Apparently they are *not* supposed to be used in cars with solid motor mounts or high vibration vehicles (IIRC they said there is a warning label on the box).

Post scrounged from the Net:

" Melling’s design of GM’s Small Block Chevy oil pump was updated in 2004, see attached bulletin. At that time changes were made to the standard volume, M-55 & M155, and the high volume, M-55HV & M155HV, pumps. The changes improved many aspects of the pumps as compared to the original GM pump. To respond to customers requests one of the areas that improved was the hot idle performance of the pump. Durability was improved by eliminating a possible failure mode as noted in the bulletin. Casting improvements allowed the wall thickness of the housing around the gears to be reduced to reduce weight. Additional support rips were added to the neck area on the high volume pump casting. For stock replacement applications the changes will only increase customer satisfaction with our products.

For performance applications Melling recommends an M-Select oil pump be used, especially in solid motor mount applications. Melling has available a full line of SB Chevy performance oil pumps. Not only does the M-Select line of SB Chevy performance pumps utilize the previous casting design but are available with design features to further increase performance and durability. In addition the M-Select pumps are CNC machined to exacting tolerances and surface finishes. The M-Select line was created to provide engine builders a cheap insurance policy to improve one of the most overlooked critical components in a performance engine build, the oil pump. "

I wasn't running solid motor mounts when this happened.. I'll give them a call later today after I get some more info.

Re: Pulled engine today and found... (pics)

I was just talking to my parts supplier and I used the M-Select in our Typhoon..> (Whew.)

We should be safe. (in theory)

The Typhoon in the picture has "South Side Machiene" Lift bars on it. The rear of the truck no longer "Squats" when launching. THey use axle wrap up to lift the body and plan the tires. On our truck it's a added benift since we are AWD it keeps more weight on the front end for traction.

You'll be stuck looking for them since they are not made anymore. It took me 9months to find my set!!!!!

The is a real bummer for Epix. I hope Melling helps with the parts and machiene work.

Taking the engine to the machiene shop this morning,
Laters, Scott!~

I was going to clean my finger nails!!!! :)

I remove that steel brackt there on the Drivers side. I also grind a small amount of allum. off the bracket by the PS pump so you don't have to take the pulley off! Saves time and it's alot easier on the pump not to take that pulley off.

The white/grey is Dalwine's buddy's truck. I've been waiting for parts from him for a few months. I got all the parts myself now and it'll be running this week. Expect a Typhoon delevery this week Dave. :)
Better make a spot.
Got the approval on Hardmans truck so It's going back in that spot this week and getting torn down.

They measure the distance from the oil pan edge to the bottom of the pan.

The Typhoon pan is 9 1/4ish deep. You'd have about a inch from the pickup to pan bottom.

If you kept a extra 1/2 quart in the system you'd proably be ok.

That would be the best pump but the regular M-select as mentiond with the 5digit PN## would be

a good proven choice too.

without going billet, what would be a comparable pump...

Moroso, Milodon, Seal Power, GMPP???

i'll be putting a new oil pump on my motor within this week. I have a M55 NIB, which I'm gonna send back, but which manufacturer should i go with??

Re: Pulled engine today and found... (pics)

The M-Select pump would be fine in all honesty.

SBC/4.3L oil systems are realy a no-brain design. They work well. It's just this company decided to "cheap" out and cut back too much on a design and ends up destroying a engine.

I'm going to leave the M-select pump in ours. Just my .02

Re: Pulled engine today and found... (pics)

Update: Called Melling this morning and told my situation. Was notified its a known problem and pump is not for any performance applications. They sent me a form, and I need to send the pump back to Summit who in turn needs to send it back to Melling. Hopefully Summit will do what I need them to do..
