Oil problems with HEUI

Now that most realize that there is a problem, how about discussing ways to fix it.
I'm considering the air/oil separation method for a street truck, but I have this crazy idea for the dragster. I was going to keep this to myself, but after thinking about it, I would rather see a bunch of you go fast.

Take the injector exhaust port and drill/tap for an Oring boss/copper washer, connect a hard line to a common oil return port then to a bulkhead fitting in the head. Now feed the HPOP from an alternate tank filled with hydraulic fluid and the return line from the heads to the alternate tank.

You use engine oil for it's original intent, engine lubrication and hydraulic oil for it's original intent.

Pick it apart.

Re: Oil problems with HEUI

So you're talking about having a separate Hydraulics system for the HEUI?
my only question would be: wouldn't the higher viscosity of hydraulic oil be less effective at trying to go through the poppet valve?

Re: Oil problems with HEUI

Wow that's something to think about. I think the exhaust port is contributing to the aeration. That would eliminate that and using hydraulic oil would help with foaming. My concern would be wear on the hpop.

We are not talking a 100,000 mile set up here

anyways Parker has a ton of hydraulic piston pumps available and I'm working on a universal billet front cover that will allow easy cam swaps as well as multiple HPOP/CP3 mounting solutions.

Re: Oil problems with HEUI

After reading the other thread I was thinking of something similair but with an oil system for the injectors seperate of the lube system.

A great idea such as yours brings up the inevitable questions like: How much will the hydralic oil change the speed or abilities of the injector, causing new changes to need to be made?

Re: Oil problems with HEUI

Hmmm, remote hydraulic fluid system. I'm sure there are plenty of sources for tanks etc. That would fit under the hood of a daily driver.

Any chance of hydraulic fuid getting past the injectors into the crankcase?

I don't know about you but I'm running out of places in my glove box to store injectors, head studs, new heads, up pipes, fuel pumps, ficms, and a lift to remove the cab.

Re: Oil problems with HEUI

The hydraulic oil is thinner and the flow rate and reaction time should be faster.

You have my interest in your mention of that front cover.

So Dave, you consider this to be something along the lines of an all-out race system then, correct?
