About catch cans

[VT86]

Looked old topics about catch cans and decided ask help anyway.

What's your opinion about catch cans, I want to delete PCV valve from intake, because it's probably broken. So what's the best way to do it?

I have plan that I remove block breather system with suction jet pump and install Adapter to block so I can use AN connectors. I have at work Catch can with two port so I tought that I use T-piece to connect block breather and head cover breather and connect those to one port and use other port for atmosphere ventilation hose which goes under the car.

Is there anything I should take were about, and is is "OK" for everyday car?


Appreciate if someone could help me out and sorry about my English

yeh thats the way to do it basically remove the whole lot, block off the pipes on the underside of the inlet manifold (think theres 2 but could be wrong), reconnect the line to the brakes,
"T" the crank breather and rocker cover together to the catch can and then from the catch can vent to atmosphere but make sure its in a wheel well or under the car as you dont want the fumes going into the cabin as they are toxic

sorry to hi jack the thread but i am doing my at the moment and was looking at this
http://www.ebay.co.uk/itm/301000472...AX:IT&_trksid=p3984.m1423.l2649#ht_755wt_1018

as you can see from the pics it has 3 ports on it one of which makes it atmospheric so can i just put one from the rocker cover to one port and one from the block to the other port?

Many thanks!

Looking to fit a catch can next month... are the ebay ones any good or should I spend the extra money on a 42DD one?

Just be very sure you don't get a can with restrictive inlet/outlets. Eg with something this:

http://www.ebay.co.uk/itm/small-oil...arts_Vehicles_CarParts_SM&hash=item2332fb43d1

the baffles are too restrictive and will end up shagging your engine if your'e not careful.


Do a search on here and see what people advise. Ive got a 42dd but to be honest I think they are too expensive for what they are..

 

[MM95]

Thanks for that googujube, will keep that in mind the 42DD one is the only branded one that I know of. The ebay one I'm considering is http://www.ebay.co.uk/itm/360780179004.

To go back to the OP's question, have you had any problems running it on your car?

 

[Hobbiniho]

iv got a ebay one the fittings were 15mm any smaller will restrict it so that one is pretty much the same as iv got except mine is square, you will need 1-2m of pipe depending on how you are going to plumb it in and a "T" piece and jubilee clips as the ones you get in the kit are ****

this is the pipework under the inlet manifold that i removed

Many thanks!

on the left side of the inlet manifold there is a "S" shaped bit thats removed with the rest of the pipes and there is a pipe that goes to the brake servo take this off the "S" bit and reconnect to the manifold its pretty simple to work out when you see it

 

[Hobbiniho]

this is on a BAM so LCR, leon cupra will be different

 

[FroggyLCR]

Hobbiniho, many thanks for that, the penny has dropped

Left hand red line in your pic, the S shaped pipe, disconect the whole lot but reconnect the brake line from the pcv side and reconect the brake line to same point, mean while,

Right hand red line, this pipe is removed as a part of the pcv system and the port on the mannifold blocked off??

Thank you very much mate, so simples when you know what you need to do, just was so worried about screwing it up, messing up engine breathing and having no brakes at end of the road........
Will now be doing this as soon as my pipe work and t piece turn up

Many thanks again again!

 

[Hobbiniho]

yes the middle red one needs blocked off under the manifold, you will probably need to remove the little cover/plate at the front to get access unless you have the hands of a 5 year old haha

Cant see that can being an issue. Some people use plastic drink bottles with wire wool in them so..

 

[MM95]

Thanks for your help Hobbiniho and googujube just ordered mine so will hopefully get it early in the New Year. Would rather keep my split PCV pipes than use a drinks bottle!

 

[285cupra-matty]

MM95 have you recieved your catch can yet?

 

[MM95]

Not yet hoping it will show up tomorrow!

 

[285cupra-matty]

Ok cool. This sound a bit weird but I dont suppose you know if a catch tank has anything inside it like a baffle or similar as my one turned up today and it was empty basically a can with three holes.
