I have 2 pick up tube gaskets, the red one and the blue one. The blue one is bigger and seems looser on the pick up tube, so I was thinking I should use the red one. What has everyone else been using? This going to go onto a Melling high pressure high volume oil pump. This might sound stupid but are there any gaskets between the block and the oil pump or no?

**Also need to know the part number for oil pan bolts and the pick up tube to oil pump bolt.

And for when I buy the heads, all of the oil passages will be closed so what type of oil should I be using for the break in? I have heard really heavy weight stuff or Rotella but what exactly?

Thanks

Regular 10W30 for break-in is fine. If you are running larger then stock bearing tolerances then bump it up to 20W40-ish but its not necessary. You can also throw in some GM EOS break in oil to help seat the rings. Its an additive that comes in a little bottle that you add to the regular 6 quarts. There arent any gaskets betweent he block and pump. Main thing is get a new o-ring, I would actually use the larger diameter one. You need to get the Melling pump and test fit to see which one works best. I have always used the blue o-rings on my truck and others and havent had any problems. If I remember right the red one is kind of square shaped and the blue is just a regular round one. Blue would be the one I would throw in but its really a decision you cant make till you get the pump. Moreso then what type of oil you use for break-in is, how you break the motor in. I highly recommend talking to Richard@WCCH about your motor build they are very knowledgeable. They caught alot of problems with my motor that I would have never thought to check. And he can order any ARP stuff or gaskets that you may need along with of course heads.

 

Thanks a lot for the information Cody. Yeah I have been in close contact with Richard about build specs and various questions I have had. The red one is round as well but once I get the pump this week I will test fit them.

 

The melling hv/hp pump comes w/ 2 orings as well as instructions on which one to use for your application.

 

really? I looked at Summit and it said gaskets arent included. We will see when it comes.

 

The pic on summit is what it comes with. Two o'rings and an extra pressure relief spring (a high presure and a low pressure relief).

I was hoping you would buy mine so I could get my beer money back.

 

I probably would have but I didnt see it. Hopefully another part I can buy.
