I picked up 8 Lowes $0.96 1/4" brass barbs (you know to adapt 1/4 pipe thread to rubber hose) for lifter valley vents. I figure it will save me $10 plus $8 shipping from summit.

I am just wondering about the brass being able to handle heat and expansion. I'm guessing just RED loctite them in and I should have problems?

Any input? I will fedex a cookie to you if you find it on google.

 

Can't see any reason why they wouldn't work for that....

Why are you putting those in, in the first place?

 

You cleanup/bore out the two big drains on the sides and you plug up the center eight. Less oil on the crank, less rotating mass, a tiny bit more hp. I'll take a few horses and rpms for $10.

 

The brass can handle the heat. Not sure about the Loctite. I'd either use epoxy or nothing.

 

I know that's why race motor builders do it (one of the reasons anyway). And often they will plug the front ones, that drain on the timing chain; and leave only the back ones open. But, why are YOU doing it? It's not really appropriate for a street motor, if that's what you're building. For example, a TPI motor will never see the kind of RPMs where it will make any detectable difference.

You know of course too, that the cam uses drainback oil.... what are you going to do to replace that?

And last but not least, that's about a pound of brass you're adding to your motor. Which is one reason for the aluminum standpipes that racing parts people use.

 

stopping oil from draining onto your cam, timing chain or crank, sounds like a bad idea.... Is it just slowing down the flow to that, or stopping oiling where it's not needed or something?

are you also modifying your distributor (slot), to help oil the cam? Since you're doing all the little things?

 

Each lifter is going to get oil, i'm also running a roller cam, so excess is waste. The crankshaft also gets oil to the pins, which intern flys off all over the place like on cylinder walls, so excess is waste.

Its a $10 investment GEEZ.

I guess its like putting a spoiler on a rice rocket...doesn't make you go faster, but this is much cooler then stupid wings.

 

Lifters always get oil. There's a passage that runs from front to rear of the block, goes right through the middle of them.

However, there's almost NEVER enough oil that feeds to the cam/lifter junction. This is particularly a problem under street motor operating conditions; idling and such. Roller cams are no different from flats in that regard. Except that you not only have the cam/lifter friction to worry about, but also the lifter roller on its axle. Those puppies NEED the oil. And they DON'T get it from the lifter feed; unless you're running Isky Red Zones or Crower HIPPO lifters. Those are the only ones that oil the axle directly. Both are solids only AFAIK, no hydraulics, if that's what you're running.

If this is a street motor, I'd recommend against it. It's not an "investment"; it's a waste, and may do more harm than good. It's really only useful for motors that spend basically their entire life above 6000 RPMs.

 

I want ventilation and oil back in the pan asap, not dilly dallying on the crankshaft. Besides, this is my toy car, I don't care about longevity, I want to kill mustangs (I know you can agree with one thing ).
