Technical chevy small block experts

The pump is the "oil lifter". I didn't know Fram made them.

I normally just safety wire the sump to the pump. The bubble flare on the pickup tube gives the wire something to bear against.

 

The one piece pan gaskets work pretty well. The gasket has to match the pan.

Is this a pan for one of the GM crate motors, which came with provisions for dipstick on both sides? and you have a 70s block that doesn't have the bump out on the p***enger side pan rail to match?

pictures of all this stuff will help...

 

The pan matches the block, the one piece gasket has both bumpouts but it should still seal with the back side edge. I will take a pic. I think i would stick it on the block with permatack so that i can be sure the rear main cap groove is sealed.

 

I've mig welded pickups for decades, and never had a problem.

 

I'm fine with one piece gaskets on a engine that's out of the car, and upside down. That lets me lay it on the block, and then secure the pan over it. But trying to put a one piece in upside down and overhead is a PITA. I wont use them if the engine is in the car and working overhead to install them.

 

Car rotisserie would be handy.

 

huh, I'm the opposite...I'd much rather use the one piece for in-the-car installations. They come with those 4 plastic screw thingys to hold it up.

 

I think the rod caps need finishing before securing the oil pan is in order.

 

Here are the pic requested. New grey one piece shown. Thin black gasket is the old rear pan gasket. New grey one look think but it has flanges on sides. Groove on timing cover does look deep. From what you guys have said it looks like there may be 3 types of gaskets, pre 74, 75-79, and the 80's

 

It would help to see a picture of the pan gasket laying on the block, and another of it laying on the pan.

then we could see if it's going to seal properly. I doubt it will seal well on the p*** side, if the block is really from the 70s.

 

To each his own. I'd much rather stick my 4 piece gaskets up with gasket sealer, and a dab of RTV at each corner. They stay in place and never had leaks. With just the 4 plastic pins I've still had the end seals slip out and had to stop and lay the pan down to get them back in place.
I have one piece on both of my g***ers, but both were done on an engine stand, so easier with them upside down.

 

I've been using Fram oil filters for decades but have read so much negativity lately that I bought a Wix for my next oil change,lol!

 

Keep in mind that the Oil Pan & the Front Cover must match.
What I SHOULD have Said is "Be SUre Your Timing Cover & Pointer Are Matched To The Size Damper Your Using".
How come my thinker thinks one thing & the fingers type something else???

I used the one piece pan gasket on my early 0010 block and no problems with the double "bump out'. I would not use the old style pan gaskets again.

 

So I noticed the old pan has a thin rear lip where the one piece gasket MAY work. The new oil pan looks similay BUT the rear flange is wide and the one piece will not wrap and seal it. See the pics. old one is chrome, new is black.

 

That's why I use old Chevy parts....they're still out there to buy....

 

That's why 4 piece pan gasket sets always came with different end seals. There's more than one style needed to seal the ends, so if you bought a one piece gasket it needs to be the exact one since you don't have optional end seals.

 

I am going to use the 4 piece set now, in the car which will be a challenge, but I am hoping the permatex hightack will keep the stuff in place. Some people brag that the SBC is the same from 55 to 80's. Not so. There is so much mismatched stuff its crazy. Like the two pans I have, both are drivers side dipstick but the rear flange differs. Only reason I am changing it is because its a $20 chrome special thats rusted to death.
And by the way, there is no way in hell the new strainer will ever come out, no weld req'd. That ****er is pressed in big time.

 

One piece gaskets are 10x better than pieces. They are also reusable....cha ching... dirt track cars use em, they cannot have leaks, or get black flagged.

The oil pan dictates, thin, thick front. If you want to piece it, i can send you gaskets, seals for both types.

 

Its the rear thats the issue, thick or thin. Hard to find a wide rear in one piece. As long as all the pieces stay up and out of my face I am ok with a 4 piece. Speaking of which, on the black end pieces, do you guys put rtv on the gasket to the pan or just dry rubber to the pan.

 

Thick in back? Might be a oil pan for one piece rear seal.... better check oil pan and block generation.

 

Look at post #46 so you can see the difference. Doubt its for a one piece seal since its an L82 block (drivers dipstick) and the pan matches the dipstick. I like the fact that its wide and flat, pretty much matches the 4 piece gasket end pieces.

 

Iam with 1971bb427, the felpro 4 piece is the way to go but it was semi hell doing it under the car. I dont need to take the pan on and off. Once in a life time is good fow me.

 

Until it leaks ..

 

I use the one piece gaskets on my 400 block, drivers side dip stick, no leaks or I would not be able to get on the drag strip. Proper tightening of the pan bolts should also be practiced.

 

The one piece gaskets I've used have crush sleeves so you can't over tighten them .

 

You need to check the pickup to pan clearance...and then weld your pickup tube to the casting. If you can't even get your pan on, I'm ***uming you haven't done that.
There's a few things you can do to insure you have a matching pickup and pan -
Buy both from Milodon or someone else who makes both.
Call Melling and the them your dilemma. Their techs are very knowledgeable and can help you get the combo right.

 

You can still over tighten them even with crush sleeves, I see people do it all the time.

 

I always use RTV thinly on the sealing surfaces, but in the four corners I use a large dab to seal where they meet the end seals.

 

I like ro put a fat bead of white grease on the pick up screen then set the pan on the block to check clearance.
