Where exactly is the pcv tube to suck in seafoam?

[ajguida]

I'm going to seafoam my engine and have heard talk about one qt. in the crankcase, one qt. in the tank, and one qt. in the induction system. Now can someone please tell me which line the pcv is so I can properly get the seafoam sucked up?

Thanks in advance.

You got some info wrong.
First you don't put it in the pcv tube. See the attached picture of this D2, look where the right tube from the right v/c hookes to the manifold. Look for the small fitting that is under the attached hose, that may or may not have a cap on it, this is where you hook a small 2' section of hose that will be sucked into the engine. When doing this, use a pair of pliars to squeezes the 2' hose that you have in the SeaFoam bottle, this will act as a valve and restrict the fluid flow. You want to suck it in slowly, over 2 minutes, then shut the engine off for 30 minutes.
During that 30 minutes I usually suggest you clean out the throttle body with a can of carb cleaner and a wrag.
When your 30 minutes are up, go drive the hell out of it, hitting passing gear as frequently as you can to help blast the carbon and lacquers loose.
As for the other SeaFoam, put one bottle in the gas tank with a full load of high octane.
As far as the crank case goes, there are better ways to clean out the crank case. Everything for adding one can of engine flush every other time you get ready to change your oil, to doing a 6 qt. ATF flush for 20 minutes on an empty crank case then do your oil change, this is probably the quickest way to get a dirty engine clean quick.
Good luck and shout if you have any questions.

Thanks again Mike. I'll let you know if I need any help when I do it tomorrow.

For clarification you are refering to the fitting circled here?

[Disco Mike]

Yes, that is the fitting. On some model years it just has a cap on it, some have a line plugged inwhich can be removed to do the procedure.

Man that's a clean engine do you eat off of it

I've been putting this off for a while as well but with over 53k it might be due, but I have a few questions.
When doing the Sea Foam treatment will the SES light come on, or is that only if you stall the engine? What if you wait more than 30min to do a hard run after this treatment, will it be ineffective? Do you use the whole can for this application? What items exactly will be cleaned from doing this treatment?
