Should the fact that my catch can is bulged be a concern? See pic

Unless it is growing a tumor, it shouldn't swell up - I'd find out why it has, and why it isn't trapping much oil.

 

Maybe its pregnant

 

Let's not follow up on that thought...

 

But it did trap alot of oil. Not enough to bulge the sides out though.

 

I'm tell ya, its preggers. think of all the other little red catch cans that will be running around under ur bonnet

 

Your blog said If your desire was bling, it really isn't very good bling as it looks now...

For the same money, here's a much better-engineered alternative to replace it: M7 Catch Can or you could go the $30 generic route.

 

I need to rewore my blog. I pulled the plastic clear tube first and removed most of the oil and then removed the drain plug. I got some out of both. Less then I thought it held. I do agree that a can like the M7 one being metal is a better can.

 

I'd ask the vendor to refund or replace it.

 

OLDRick could you expand more on this valve which could be blocked? How would I know or how to clear it if it is.

 

Could just be a weak spot in the silicone. I'd be happy to replace it. Give me a call! It shouldn't be any big deal until you get the new one. Are you getting a lot of pressure in it? If so, check the coolant to make sure you don't have a head gasket problem - there would be oil in it.

Hope that helps!

Thanks Randy! I will talk to you tomorrow.

 

As to a check valve, I'm not sure if there is one in these cans, or if they use the stock PCV valve, but there is a check-valve somewhere in the path to keep outside air from being sucked back into the crankcase. It lets blowby pressure out (and feeds it back into the intake) but doesn't let outside air back in.

The whole point of the PCV system is to release the dirty air that leaks by the valve seals and piston rings into the crankcase, without letting it get out into the atmosphere as pollution.

If the PCV valve sticks, then the pressure can't get out of the crankcase, and can, in the worst case, blow out the main seals on the crankshaft. Usually the hoses pop off the valve first, but there is always that chance...

Since it is emissions-related, the manufacturer is required by federal law to provide a five-year warantee on it, is my understanding, so I'd take it to the dealer to have it checked.

However, if it is a standard PCV valve as used on most cars, the simple answer is, remove it from the path, and try to blow through it then try to suck air through it. It is just a one-way check-valve, so it should allow you to do one but not the other if it is working correctly. Then it would be good to verify that it is not installed in the wrong direction, allowing outside air in, but not crankcase pressure out.

 

I'm willing to bet Randy is correct. MDSBrain just got his baby back from the dealership with regards to a head gasket problem.

Alta have anything to say about this? PM Alta2 here on NAM... Everytime I have, I've gotten good response from them.

Any other record of bulging cans? This is the first I've seen.

 

Maybe...but my dealer also mentioned I might be pushing to much boost . I'm not sure which it is. I'll talk with Randy later and I have PMed Alta for their comments.

I am slightly confused as to how to check if there is pressure in the can. The bulged can is bulged when its in or out of the car. Would it of bulged from pressure and stretched the silicon?

 

I'd would be interested in one of the offspring. The adult model is just too expensive.

 

He could put the babies up in the marketplace but I would bet they would be worth a fortune on eBay!!!

 

Yep - exactly.

 

We will replace it also, Randy don't worry about. Most likely it is because the can is seeing boost(which it can take but not normal in the CC install) You might have something hooked up funny. How do you have it hooked up?

 

I talked with Randy about the can. He told me something to check on my car and I will. I'm not going to make a fuss about it unless I find something funny.

Edit: The can is hooked up however Randy installs it.

 

It it worth noting that silicone hose is not rated for containment of oil, gasoline, or toluene, all of which are present in a catch-can. It has little chemical resistance to these liquids.

By the time you change it, your oil will contain several percent gasoline, and if you ever use injector cleaner, it's a good way to get some toluene in there.

For lots more information read this report comparing hose materials...

 

Jeff,

I've got it taken care of, but thanks!

I spoke to the "brain" today, and we have figured out that it most likely was related to a head gasket issue he had. With that fixed, the pregnancy should be limited to the one time. We confirmed the vasectomy on his car!

Hope that helps!
Randy

 

Great! Simple solution just change the head gasket! Just kidding. Keep us posted as to what happens, and let us know if you need a new body.
