Sea Foam Intake Treatment 03 Marauder

Did the Sea Foam treatment on my 03 Marauder today. I went the spray can route. I pulled the plastic pcv valve tube that connects to the right side of the intake and covered the opening of the tube with duck tape. I then poked a pin hole in the end of the taped opening to lessen the amount of vac loss during the process,...I really did not want want to throw a code. I then placed the little red tube that came with the Sea Foam in the pin hole, connected the tube to the can of Sea Foam then blocked off the pcv valve opening. After starting my car I carefully sprayed about 6/8's of the can into the intake then shut the car off for 15 mins. After starting her back up, I took it out to the highway a blew her out. It smoked and ran a little stumbly for the first 3 mins while it was exhaling all of the dissolving varnish, crud and excess Sea Foam. However after it was all cleared out,...I could feel WAAAAAAAAAAY more bottom end grunt and mid range pwr. RPM recovery between shifts is alot faster and the motor just feels more crisp. Kinda like the difference in how a car pulls on a 30 degree day vs how it would pull on a 90 degree day. Air temp on the coast today was a pleasant 80. I highly recommend this procedure to all my fellow Marauder owners.:banana2:
 
Ahhhhhhhhh,...yeeeeeeeaaaaahhhh. Its dang near the same last I checked. I just know that the car runs much, much better. I am going to put a JLT Air/Oil Sep on my car to aid in keeping sludge out of the intake tract.

I prefer to use the liquid Sea Foam. What you don't use you can add to the gas tank.

6/8..... NICE!
 
Man I am really in trouble... I used 12/16ths of a can.
Well, I found out by installing a JLT catch can it has minimized the dirty intake issue.[ personal observation] also I have used Sea foam ,poured slowly into the vacuum line from the brake booster with the engine running at about 12 hundred rpm.-did a great clean up job.:burnout:
 
Vortech347,...it actually does work quite well. The air/oil seps are also very effective. I had a 93 Mustang a Eddy Performer RPM Intake that had the removable plate on the drivers side. I would take the plate off twice a year to clean the oil residue out of it. That crap really makes cars sluggish in summer months when you need every octane point to count. After installing the air/oil sep, the intake would have little to no oil residue inside of it. I have two of them on my 10 sec. 87 Coyote Swapped Mustang Coupe. The Sea Foam Treatment works,...I did last my Marauder last Sat and wow. I have never tried water or brake fluid to clean the inside of the intake,...but if Fast Black Merc says it works, than I am a believer. I have had great results with 2 + 2 and CRC throttle cleaner for cleaning throttle bodies and IAC's

Water or brake fluid won't clean the intake, it will clean the carbon out of the cylinders. Used to pour it down the carburetor.
 
Using a bore scope before and after I showed ZERO difference on the piston top. Didn't remove a damn bit of anything.

The minor amount of oil build up doesn't really effect anything on a mostly stock, non modified car. If you're boosted and you are running on the ragged edge with crappy fuel and within 1* of timing for destruction and you would still need a pretty significant amount of oil to start having issues. But if it makes ya sleep better at night and the subliminal butt dyno says "OMG!" then go for it. But its a waste of money.

Personally the best looking pistons/valves I've ever seen on an engine that had 20k+ miles on it was a my fox or other with Meth/water injection. Also blown head gaskets putting coolant in the chamber also cleans things up pretty good too. haha.

On my fox I made life easy, PCV system gone. Zero ability of any oil into the intake. Breather on a catch can.
 
My car feels way better,...thats a fact Jack! Open element breathers smell. I cannot stand that oil vapor smell. Gives me a headache. Have not tore into the 4.6 in Marauder and I hope that never have to,...but I did do a couple cylinder changes on my push rod 5.0 and the amount of oil, carbon, varnish on the valves and piston tops was next to none. Not a waste of money at all,...
 
Its in your head. Show me a before after dyno and then I'll be a believer. But if it makes you feel warm and fuzzy great.

But like I said. Using an HD borescope before/after showed ZERO, again, ZERO changes.
