as the title says , is it worth doing the PCV delete on my s3?
 
The other point aside from boost leaks is that a PCV delete kit will not solve inlet valve coking.

There is,but it's not a cheap fix.



Integrated Engineering make a complete cam cover,and catch can system that includes the crank and cam breathers,and deletes the sneaky one at the rear of the cam cover.

I guess you have to balance the cost of this lot Vs the cost of regular decokes.

How much should a decoke be costing ? Around about figure ?

Not expensive and usually below £200 but you need a current quote.

If you keep the and/or have it mapped etc then it may be worth considering getting rid of the problem.

My point about the catch can is it doesn't really deal with the coking issue but it does deal with the PCV leak problem.

I don't seem to getting the boost leak problem off my forge delete but would like to get it decoked as coming up to 70k and doubt it's ever been done
 
There are breathers to the rear of the cam cover which empty into the turbo inlet.

This is the problem as these kits don't remove or bypass them.
 
The later PCVs are much less prone to failure so I wouldn't bother personally.

Depends if you want to stop it cokeing up or happy to keep paying to have it decoked , new pcv may not fail but the new pcv doesn't solve the cokeing problem

Exactly.

I think the problem is exacerbated by higher boost levels,but it's still a problem over time with stock engines.

The 8V engine gets around it with both direct,and port injectors,but unless you have either the cam cover and breather system like mine,or a port and direct injection setup(mine has this as well),you are still going to suffer coking.

I have a full set of before,and after pics on my thread,plus some taken about 6 months after a decoke,with all of the stuff back again.

With mine going stage 2 today (currently sat in bcs waiting room ) I think I'm going to get mine decoked over the winter when I have the cam chain and tensioner done before I get my coilovers brakes etc fitted

It's easy enough to do,and quite quick.

If it's in bits,then it's so much easier and makes good sense.
I think it does make an obvious difference when the inlets are well coked up(!) and the engine does breathe better after.

I'm not all clued up with the engine Lay out etc but I no the cam chain is on the right hand side as you look at the engine from the front the tapping g from the slack/stretched chain on idle is driving me insane ! You would be amazed how many 'specialists' say o they ain't chain driven you mean u want the cambelt done ,at that point it's bye bye

As has been mentioned earlier, adding a PCV delete kit does not prevent the valves from coking up. There is no cheap fix for this IMHO and I doubt the OP will want to go as far as Alex has?

I think few would...LOL

There are two reasons for me doing this.....firstly I'm not selling the car any time soon,so it makes sense there,and secondly it looks good.

Having just completed the de-coke at our workshops, my IE breather system and cam cover should be delivered very soon now.
If any of you require your DI TFSI engines de-coked we have the specialised tooling to carry out these works using synthetic blast cleaning media, and all in situ.

Good that a few forum guys have got these facilities now.

Maybe a list somewhere would be useful.

I installed a PCV delete kit and took it off again. Car didnt idle properly and I just really didnt like it from the word go. Never mind the fact it didnt even sit straight when fully tightened up. I have posted pics in various threads on this forum about it.

Please send the links to the forums for where you did this and how it didn't sit straight
 
Here's a pic of mine. Had no problems just as yet. However most of this thread has had me scratching my head. I'm a little lost.

Yours looks like a cheaper Chinese one where you can ask them to engrave a company name, I'm also going to try a cheap one first and see if I experience problems.

Look what I found on AliExpress

Try Garage midnight. You won't have to speak Chinese!

You are right, The integrated engineering one does look like a better quality option

I'll try one of these which look to be a closer match to the IE one you have.
