Hello, my challenger has about 9000 miles on it, had a catch can on since 1500 miles, I just now emptied it and it was full.

Good thing right.... the catch can is working, bad news is that diablotoona discovered my car is knocking pretty bad via data logging on my new inTune. He recommended that I use sea foam treatment on my intake via the vacuum method.

Has anyone done this and if so is there a video or thread some where with instructions?

Thank you

becareful , when useing the vac method , you can fill intake manifold with too much sea foam and then when you rev up to clear it out you can injest too much sea foam and hydalock engine = major damage

I would suspect the InTune data, and would not do the sea foam.

If there is an engine problem, I would look for warranty service from a dealer.

I'd keep a closer watch on the catch can like every 1000 miles or so and should be no more and an inch deep at that point. If it does fill and go over you'll suck liquid oil rather than oil vapor through the tubing.

I just looked on the Seam Foam site. They have a Spray version with a hooked tube that is placed 1/4 " from the throttle body Blade just under the intake tube. 2 1/2 minutes at 500 RPM over idle RPM.

Probably try that method. I don't hear any knocking, but a full catch can at 9000 miles does that seem to much? I have a Billet Technology can.

I empty mine every 1-2k. I thought it would be more like every oil change schedule. Good thing I read someone post the much quicker cc emptying time frame before I had mine on very long.

I have seen youtube videos of the seafoam treatment. Will have to search for a Challenger specific one though.

NO, the more agressively you accelerate will add oil at a faster rate. I'm fairly easy on the car and in 1000 miles I can have 3/4 of an inch.
Unless you know for certain there is significant oil in the intake I'd skip the seafoam.
If you're set on doing this and you never did this yourself, I'd get someone else who is comfortable using it to do it for you. Hydro locking the engine won't be warranteed. Good luck.

It's pretty scary to think that without a catch can, and me being first Hemi, had no idea it was needed until I joined the forum. All the people that drive and enjoy driving there hemi, hard accelerating. Getting all that oil going into there intake.

Seems to me that there should be a factory solution to this problem.

I say CC needed, I did the sea foam treatment, was easy, 1 tx almost 1/2 can, the data logg showed a lot less knock. Gonna treat again in a few days.

Also going to order a Z bracket to make it easier to empty.

Great idea, you're going to like that option.
