If so
What kind did you use?
Where did you mount it?
Pics please?
Gonna put one on mine.

 

Why do you think you need one? Are you worried about carbon build up due to the 5L being a DI motor? I know some of the Audi DI motors have horrible carbon build up but I haven't heard any issues with the 5L Jag motors.

 

Several guys on the S Type forum have installed them on the 4.2L SC engine. Have not seen any benefit. Yes you catch some oil so the intake tract stays cleaner and you don't put oily junk into the intercoolers.

So I think it's a postive but just has a very small effect.

I haven't seen a catch-can on a car newer than ~1970. Not sure why you would need one. IMHO It's one more thing to go wrong or need cleaning.

 

Got this information from another forum. The best way to set up a catch can is actually to use 2 of them, one for the breather side and one for the pcv side. This way, the original routing of the pcv system is intact but catches oil from both sides while allowing the manifold to draw out these crankcase pressures. A company in the USA called saikou michi make a dual can and can custom make them for your application.

 

To address both post my concern is what will happen over time. All engines pull oil into their intake tracks form the PCV system, boosted motor even more so, add to that synthetic oil which will not readily burn off, but will pool, cause timing killing detonation and as mentioned gum up the inter-cooler, I think its just cheap insurance. Coming up from GM's LSx engines where catch cans are the norm, I was just curious if it had already been done here.

 

Never heard of any of that on a Jag S/C engine.

 

This is very common on boosted engines.

 

Can you point me to a thread specific to problems found on a Jaguar?

 

Sorry, I can't. But with turbo and supercharged engines it's very common. I guess there is no data relating to Jaguar cause usually they are not tampered with mods and upgrades.

Most people just buy a Jaguar and drive it. But now since jaguar is starting to get some aftermarket support for performance, things might start to arise. It can't hurt and there is a benefit to a catch can, I will post a video when I get home.

 

I understand the concern and the fact that it affects other brands of cars. Supercharged Jag engines have been around for quite a while. No one has made mention of this specific issue so this seems like a solution in search of a problem.

 

You keep referring to Jaguar and other makes. Carbon deposits don't care what brand car you have, every make gets them and it affects performance.

And yes, there are many Jaguar owners who have used Seafoam to correct this problem. I have seen cars lose as much as 80hp do to carbon deposits. So it would not hurt to add a catch can. It would be preventive maintenance. And all engines love to be clean.

 

Ahhh- Seafoam!

This magical fluid is composed of 50% light mineral oil, 25% naptha and 25% rubbing alcohol. Nothing more. Go look up the MSDS sheets.

This product cannot remove heavy baked on carbon deposits by trickling it down the intake. Not even extended soaking would have much effect.

Again- I'm asking for evidence ON JAGUARS of such contamination.

Just because you have not heard of it dose not mean it dose not happen. My experience is a catch can is needed, your experience is a catch can is not, so you do you and I'll defer from trying to prove to you that a catch can is needed.

 

Let me know what you come up with, it would be interesting to see if the pool of oil diminishes or disappears with the catch cans.

Even though the oil is supposed to be there doesn't mean I like it there.

 

I think I'd worry more about why your engine lost two quarts of oil in 5K miles.

 

Mikey you ask for a forum post, that was it.

boiler My car looses no Oil. But I will detail my install and its results.

 

I don't think it lost any oil like I said before IMO the idiots at the dealer didn't put enough in.

 

There might not be much evidence on 5L Jaguars because the 5L isn't old enough yet. Here are some threads on the topic. Some posts site issues and others say they haven't noticed issues. You've posted in both threads though so you should know about them:

5L thread: https://www.jaguarforums.com/forum/x...charged-94489/

4.2L thread: https://www.jaguarforums.com/forum/x...g-techs-62712/

 

Correct. If you read through those threads, there is no evidence of any issue that would cause the sort of problems that the OP is predicting.
