r-tech pcv delete or catch can???

[Stooey]

I'm looking either fit a catch can on do a pcv delete but I'm unsure which is better? What are the pros and cons for each? I'm guessing the r-tech delete will be better as they know there stuff but just after finding out a bit more if anybody has any info.

Cheers

I've seen a lot of mixed views on this. A catch can is probably my choice, as deletes can cause excess pressure inside the engine. plus a catch can filters some stuff from passing through the engine.

Thing is you need to get a well designed catch can to make it worth while, think the Draft 42 Designs one was mentioned as a good one in the apst but don't quote me.

The catch cans are no better than the deletes, all (aside from the R-Tech setup) reduce the breathing capacity of the engine (both cam and crank) down to a 19mm hole (or less), which does cause excessive pressure and leads to smoking on overrun/idle.

The R-Tech kit runs a separate large bore breather for the cam and crank gases. No back pressure, no hot oil vapors making their way back in to the turbo intake etc.

Get the R-Tech kit - Cheaper than a decent catch can setup and does a better job

I may consider that myself actually, thanks for that.

Thanks for the reply lads, think the r-tech delete is the way to go then

Looks like R-tech have stopped selling this now 

[v4rley]

Yes they have, but apparently AKS have started to make / develop this own now

Wonder why they stopped making them?

I've just opted to replace the front and rear PCV with new OEM ones. The rear PCV is original so on 128k miles.

Because PCV deletes causes issues with crankcase pressure and burning oil/smoke. Mine was OK at first but started with age/time. I'm now back on the factory PCV and will be keeping it that way

Thought so. Thanks dan.

Went to pick the stuff up today and the rear pcv doesn’t have s valve in it. Just a flexi metal hose and short rubber hose that attaches to the cam cover. Is that right?

Thought it had a valve in it.

As long as you don't have a P revision front PCV, then it doesn't need a checkvalve. I'm currently using an N and the latest is R - both are fine without a checkvalve in the rear pipe

Lovely. Thanks agains. I’ll replace the pipe anyway as I am stripping it.
