Which PCV Delete

[jaylufc17]

own a mk5 gti dsg running stage 1... looking to delete the pcv... seen the following... any recommendations?

R tech delete is the only real delete

Stop the intake valves getting covered in crap, or it atleast slows it down massively

I have the forge version which i picked up 2nd hand off here, purely because I had an air leak from the OE PCV. Cant complain with the forge one...fits nicely and looks the part

So does this delete kit contain everything you need or do you need a catch can or something like on awesomes website?

Which kit? The R tech one? If so it comes with everything you need. It doesn't use a catch can it vents to atmosphere.

Cheers Chris, I was looking yesterday and it seemed like there were about 4/5 things that were associated with the delete kit and it got very expensive as I thought you needed all of them, that's why I asked in my other post

↑ This is not true. A Catch-Can in place of the oem PCV...yes, but not the stage 1 PCV delete. The "stage 1 PCV delete" keeps the recycled vapor path open all of the time....rather than just when there is boost pressure. So when there is vacuum in the intake manifold...the intake is able to suck air from the intake before the turbo because it doesn't close the path...not that the engine is using the turbo when vacuum is present

Basically, when you do a stage 1 pcv delete...you keep the path open and vapors always have to pass through the turbo whether under boost or vacuum and all of it ends up passing the intake valves eventually. With the oem pcv...the vapors take the long way under boost and then go directly into the intake manifold under vacuum. The catch-can is the only way to remove some of the gunk. I say run the oem pcv unless you go through them on a regular....or do a catch-can if wanting longer intervals before the need to deal with valve cleaning.

The r tech one is a 100% delete all of the time. It's deletes both front and rear pipes from going back into the engine and vents to the atmosphere. This is the only way to go in my eyes

I stand corrected...and apologize as I completely dismissed the VTA set-up. The R-Tech is a vent-to-atmosphere system. I didn't look into your suggestion and thought it was a reference to a "block-off/stage 1" the OP was asking about.

It's a moot point anyway because even with a 'full delete', the valves still carbon up from exhaust reversion.   Port injection is the only way to keep them clean.

If you want an easy life, just stick to the OEM PCV and replace the front one once a year or something if remapped.   Carboned up valves makes little odds in terms of flow with boost.  Mine's on 107K miles with tonnes of carbon build up, but still drives great and still makes the hp

I agree. I cleaned my inlet valves recently and it really made little or no difference. I think With a highly strung N/A motor (like an RS4) it'll make a difference but with boost I'm not sure the carbon makes much odds

I switched from my stage 1 back to oem and it's never blown...I do a valve blow-by every year to clean them using fuel/petrol and a bit of solvent.
