I am keen to see how much this Forge kit is going to cost and will pay paying close attention to the £/$ comparison. If it is gonna be ridiculous and in the Americans favour as usual, I will probably just renew the OEM item at every second 3000 mile oil change as they are not that expensive.

Oh yeah never thought about that :whistle:

Ill wait to see what price the forge one will be and go with the most cost effective option. :)

Djhorace,

Will replacing the OEM one every now and again fix the problem though? Does it not recirculate the crap into the intake valves regardless if its a new OEM or old OEM PCV system?

It seems to be accepted that the stock PCV is prone to give issues over time. Although I have not seen any detail of why or over what time scale the stock item fails, similarly, I have not seen any proof of how aftermarket ones magically make all issues disappear.

**Important Note**
Customers in regions of the world that drop well into the freezing temperatures during the winter will need to keep a watchful eye on the volume of water collected in the can. One of the main fluids caught in the can is condensation (water). In the winter months the amount of condensation caught in the can will dramatically increase. If left in the can in freezing temperatures there is a possibility that this water could freeze. If frozen, pcv flow will be inhibited. Make sure to keep an eye on your fluid levels.

Also, you end up having to add crap in to your engine bay which clutters it up and looks ugly.

For what its worth, I seem to recall the stories of the recirc valve being an issue on TFSi Cupras once upon a time, but I have not known of many that have failed on the Cupra due to it being located on the front side of the engine away from the heat of the turbo although it was certainly an issue on several FR's/GTi Golfs etc. Scare stories/negative news sell parts however even though sometimes the issue may not directly affect some (ie the Cupra). Funnily, however, there is now an OEM "D" revision valve with a spring instead of a diaphragm which does away with the argument used for having to "upgrade". You then have a choice of a £50 valve from your main dealer or pay 2 times that (at least) for an aftermarket one that does not give any additional performance/reliability etc gains.

If the PCV is such a large issue or problem, I would imagine VAG will be working on a way to replace the PCV with a better item or they are going to see a **** load of warranty claims come time.

In the mean time, one can only assume that the PCV needs to be treated as a servicable item in my opinion or look at the aftermarket alternatives available. I will probably look to change mine every 3000 miles with the oil and filter.

Oh yeah, and that BSH kit is $274.99 or approx £167 at todays exchange rate or £192 including VAT plus whatever delivery might be (I can get stuff shipped in with work orders), so unless Forge is around £200, I would go with the BSH option if I decide to go down that route.

i would see foge with a new procuct to market over the £200 tbh , is the catch can part of the kit? if so just have a look at costs of catch cans and you will see why this could be a very expensive mod.
i think when my warranty expires in 2011 i will be selling my car , and seeing what else is about.
i think a large bill for intake valves is something i would want to avoid [:@]

The catch can should be part of the kit I believe. As a function over form man, if something serves a positive purpose, looks are secondary, and to be fair, none of these kits are exactly appealing to the eye.

A shiny and polished a catch can being part of the kit is no more of a bonus to me - in fact I would prefer something more subtle that blends in with the rest of the engine bay like the BSH kit.

djhorace,

Thanks for the in depth response mate. I take you point about if it was such a big issue that VAG would have a revised PCV system out to fix the issue (if there is one?).

I think I will just price up the standard PCV and replace it like you are doing every time I change my oil and filter and see how much or how effective these systems are.

I also agree with the point about the thing doing a job rather than adding bling. Although if the forge items were anodised black they would be much better looking.

Replacing the PCV valve every X miles isn't going to stop the intake valves getting gunked up though as the oil mist/vapour still makes it way through :think:

It will avoid having a PCV valve that becomes overgunked but the problem of the oil vapour/mist making its way to the intake valves and settling on them will remain.

I may be getting mixed up here, i thought the problem was the intake valves getting gunked not the PCV valve itself but since they are both related i guess its a combined issue.

Sounds like a good idea to replace the PCV valve every so often - i just wonder if there is an easy way of actually cleaning the intake valves themselves - probably not!!!

I am also guessing that something like this would be worthwhile every so often too :)
