Friend of mine recently bought a Mako with a 454 build by Pinkston Energetics. It has a piece of braided hose between the left and right block drains. No tee, no valve, nothing but a line connection the two side. What purpose would this serve?

The only thing I can even come up with would be to equalize both sides of the bock pressure wise....

I dont see a bunch of value though...Unsure

I would guess a sediment trap or the installer wanted people to think he knew something they didn't.

im going to agree with earl brown, i havent seen it before either, maybe an equlizer, maybe tom would know

Kind of stands to reason that the function is prolly to do like whats already been said above (equalizer) , actually kind of an interesting "concept"

I kinda had thoughts like that years back, but thought better of it because the banks on v style engines are already balanced, pressure wise, through the intake manifold.

However, on most engines, this crossover is only on the front of the intake manifold. I have to agree here, interesting concept, and might have some actual merit to it. Cylinder to cylinder temps might have a real benefit from this.

Just throwing this out there because I've never heard of it done this way before, but the crossover in the manifold on a BBC (and others) is "after" the flow restrictors in the head gasket....

I am unsure of any real benefit but at the same time don't think it could hurt, now if it had a tee in it, and being as small as it is (block drains are only 1/4" NPT) by installing a small dump line overboard could sure eliminate some sand deposit problems.bulb

I have used the same holes, but drilled to 1/2" for the water "in" on a jet before, actually with great results....Unsure

The hose was completely blocked with sediment. He cleaned it out and I think he is going to put it back. I didn't ask how big the line was.

Chad, Sign up and post up. How big is that line?
