new catch can big crankcase pressure

[googujube]

Hey up

thought I'd warn you about my catch can hassles over the last week. Hopefully might stop someone making the same mistake.

installed catch can last week, one with 19mm inlet/outlets. I ran the car for a couple of days everything seemed alright. Came to start the car one morning and noticed car was kicking a bit of white smoke out, I put this down to cold morning etc. Started car later in the day and this time smoke was much worse..drove to my local mechanic and he saw that engine was under far to much pressure..diagnosed catch can was not letting air through. Vented to atmosphere and problem solved.

anyway took catch can apart examined it and the 19mm in/outs have an inner circumference of about 8mm..on top of that the outlet was far too restrictive. When I took it out I couldn't even blow through it. There was some yellow gunk etc in there but it was nowhere near full..less than 1% full.

Yeah I should probably have checked it out first but just got on and fitted it.

one a positive note after the Pcv and n249 delete the car feels brilliant.


hope this catch can hasn't damaged engine.

Isn't the ID of the hockey puck like 6 or 8mm? I want to get rid of my pcv but I can't decide to vent to atmosphere or fit a catch can!

Yeah puck isn't 19mm I think the issue is more that the catch can wouldn't let air through it. Could have been potentially serious..providing no damage has actually been done.

feels good vented to atmosphere.

What route did you take with the breather pipe venting to atmosphere?

can't link to it now because I'm using my phone. I linked to it in the draft 42 catch tank thread..think you posted in that thread actually?

could this have paggered my engine mate?

Crank t's to rocker venting under car. Stuck a bolt in the tip.

 

[googujube]

Forgot to add that the screw in baffle on the can is also far to restrictive..

 

[vagman2001]

You still using an undertray?

No, knocked up a makeshift can with wire wool to catch any gunk,obviously don't want to dump anything on the road Only a temp measure until I get a good reliable tank

Ill check mine over and let you know if that's ok pricey mind at £88 delivered but works (I hope)

Im not on about the 42 draft that looks pretty sweet

Now I don't feel quite so mad spending money on a saikou michi can.

Buy cheap, buy twice!

No smoke from the Mocal one I've been running for a good 7 years...

 

[Seal_LCR]

I have the 42 draft one in mine no issues as of yet!

 

[googujube]

Got a feeling you wont have any issues..will look at the Mocal and 42 draft options.

 

[Seal_LCR]

Was always told buy cheap buy twice! Still have done it though never no when you might find a working bargain but that's the chance you take
