OK trekkie. Yer right about the source of the pressure not coming from blow by on the valves. I just pulled that one out my arse on the spur of the moment and later regretted it (but not enough to go back & edit the post). It's probably a combination of blow by on the rings and simple heat expansion of the air in the oil system.

Yer also right in how I used the acronym PCV. The V part does in fact ruin the point I was trying to make.

Yes, the fact that I'm admitting that you were right is paramount admitting that I was wrong.

Just remember that it's only been you who has been making it so much a matter of who is "right". I was simply trying to save you some unnecessary effort based on your idea about how the kind of system you're wanting to modify actually works.

And seriously, trekkie? Again? You do realize how you make yourself look when you do stuff like that don't you?

I won't hesitate however to post my results (positive or negative) whenever I get around to putting on a crossover pipe. If for no other reason than to prove you wrong. Negative results are almost as beneficial as positive results as long as you learn from them.

That you're automatically assuming that your results will prove me wrong regardless of what they are says a lot about your probable methodology and interpretation of your own results.

My first attempt at reducing oil consumption did not cure the problem but it certainly helped (& shouldn't have by your logic).

Seeing as how I don't know what your first attempt even was, I can't respond to your comment about what logic you're even referring to or whether you proved it wrong.

Question: If a crossover pipe on the valve covers will be of no benefit in your opinion, how do you feel about crossover pipes on a dual exhaust?

First of all, you're assuming that the two situations are the same and they're not. Crossover pipes in exhausts are meant to equalize pressures from both sides of an engine that are positive all the time with no source of vacuum to relieve that pressure. That kind of crossover pipe is just used to try to further equalize the BACKpressure in a dual exhaust system.

But the fact of the matter is that a PCV system on an engine ALREADY has a crossover pipe of sorts that's achieved with the oil drainback passages in the heads and block that Scott referred to earlier, making a crossover tube from valve cover to valve cover redundant (which is pretty much all I've been saying).
