THP low lumpy tickover when engine warm?

[Chris_Blue]

Catch can a must i reckon. Once youve built the frame for the catch can to go on, replacing all back to OEM is about 10-15 minutes
Dont seem to have any engine bay pics of my 150- or theyre on a USB stick somewhere round the house

Catch can.

Catch can it is I think,thought it was going to be a major operation but looks simple enough,any opinions or advice on where I can get one from and is it best to do both front and rear pcv's?

Cheers.

Have a look at a few other related threads Darren, but deffo start with the front PCV. 19mm pipes on the can, and make sure its baffled (I got one with sight tube)
To be honest, you dont even have to fix it to start with- its just a metal can that acts as a filter, with a bit of pipework

[Darren6645]

Thanks Chris I wasn't sure if people had used specific cans for ds3 or citreon but looks like not a lot to them and plenty on eBay.

Saikou michi is a quality option

Found them on EBay £110 & p&p but out of stock until January.
Are both hoses required 19mm both ends?

[Chris_Blue]

Thats about right price. No- have a look on other catch can threads which should detail sizes, 3 ends are 19mm ( 2 at catch can 1 at either air intake or rocker cover) but from what i remember one of the ends at rocker cover or air intake had an internal diameter of 25mm, and had (For the pipe i had) to get a reducer from 28mm, which was external diameter of pipe coming from Catch can, to the 25mm of the air intake (I think it was)
But check on the "Catch can" thread

PM me your email if you wanna piccie

My 150 has slightly different sizes so as CB says check on other threads. I've not checked mine for a few weeks but has remained dry since I fitted it during the summer.

[Chris_Blue]

Mines been dry thru summer- winter is a different story.. most of it condensation I would say.. but some goo certainly not as per my catch can video thread
