Mc funbot, I followed your n249 bupass guide few months ago and you helped me when my EML kept coming on which I appreciate, top fella. Do you have a pcv delete guide? And can you recommend a catch can? I see people using toyosport cans with 15mm inlets sleeved to 19mm http://www.toyosports.co.uk/oil-catch-tank-round-9mm--15mm-fittings-black-3299-1415-p.asp are the 15mm ok to use or would you recommend one with 19mm inlets. Cheers mate

Catch cans are good BUT 1.8t rely on breather ive know of problems with 15mm ports as the crank pressure changes. My brother machined myn out an made then 19mm so its all as it should me. I need to make guide but I dont have a car to do it on. UNLESS. Someone wants to drive to northampton an let me do it?? Whos game?

I've seen people using the 15mm ports with 19mm pipe work and seems ok? Your over 2 hours away so quite far from me. Can you recommend any cans?

I'm game mate what would I need to get and how long would it take to do it.

I can do it in an afternoon pal. You would just need your car I can make you a plate up and remove all the other bits.how far away are you from me?

19mm pipes on 15mm ports is ok just doesnt breath well. Increase in crank pressure an can cause oil to leak

I'm about 45 mins from you mate so not that far. I'm free any time to as I've just been laid off lol.

Thats not bad then pal.. could do an evening mate in my garage/man cave/the work shop/ hide away from the misses.

Hahaha yer sounds good mate it needs a good going over as it was a bit of a nail when I got her. Spent a small furtune on it all ready, seems like as I fix 1 thing some thing else gos lol. Need to find this leak though as it stutters like f**k when I floor it at around 3000 rpm.

Mine stutters intermittently when pulling away from junctions. Do you think PCV delete would cure this? I've done the n249 bypass and replaced the CTS

 

[b3nm33]

I've done the n249 bypass replaced most of the breather hoses had a new cts and still I get it, there is a code that comes up pressure drop between Turbo and throttle valve. Any help with this would be ace

Same here but I don't get a splutter I've rather got full boost or limp mode when it brings that code up till I turn it off and back on again but we think its my dv that's the problem

 

[b3nm33]

I thought it was my dv but I replaced that with a forge splitter r and it still happens. Mine does go in limp mode ocasionaly to.

I don't have any codes or anything......

 

[Longy82]

That's what I got and they apparently a bag of poo on these engines so just going to try a stock one and take it from there as when I adjust it it goes into limp mode quicker then adjust it back and still goes in limp but after about 20 mins or so.i just carnt win wiv this dv so hopfully this is whats my problem as I have no leaks at all.

 

[b3nm33]

Can't you adjust them so there fully closed though, and I've talked to a few people that say theyve had no problems at all with them. Need to find out how to test my standard dv see if that was f**ked

My o2 sensor light is on to as I have a Dec cat on it but don't think that's the problem.

Don't think so mc funbot has been giving me some great advice on what to do and try and not to try so just going to try a stock one and see what happens so see if I can get rid ov the codes 17705/16795

 

[b3nm33]

What's he said to try mate need to get rid of this asap. I have the first code you listed.
