Well.... finally got around to pulling off my intake and was very happy with the results ..... 47K miles ...seafoam every 4-5K since new . I cant get the other 2 cyl pics to transfer but they looked the same ..... a very light coat of gray carbon on the botton of the valve and a little build up in the middle of the stem. You can still see shinny metal at the tops of and in other parts of the stem . Car was seafomed 2K miles ago . Mobil 1 every 5K 93oc always. Ill work on the other 2 pics . Ohh... forgot trifecta 24psi for the last 40K ..... superchips for the 4K before this ....mods in sig.

 

I still have to do this

 

This is how I do! Seafoam every oil change. Nice to see proof that it is cleaning!

 

RUKKEE we need a range/race day damn it!

 

I know man...... between family crap and weddings summers gunna be over before I have any fun lol. Did you see the SCCA autoX they set up in Ralph Wilson stadium this weekend?


Here is the rest of the schedule ..I guess non members can buy a weekend pass for $15 plus entry fee's . I'm gunna try and get in touch with WNY SCCA and get details cause I would love to do that .......plus get up to NYIRP atleast one more time this year.

September 9th - OOR @ Lake Erie Speedway
September 23rd - @ Ralph Wilson Stadium ***Champagne Run!***

 

Yep...... I was very pleased not to see what some others have had to deal with . There are some LNF intake valve pic's here that were so bad ......I had to pull my intake to just for piece of mind 8)

 

I never had mine off my LSJ but it looks like quite a job ! I had my blower off in like 10 minutes but the rest of it looks intimidating hehe. At least the LSJ's have gas to clean off most of the gunk i would imagine .

 

yeah the lsj shouldn't be anywhere near as bad as the lnf.

 

That looks pretty good! I wish the pictures were a little more in focus and were zoomed in a bit more around the seat area.

Thanks Rukkee

 

Anyone have a how-to to seafoam a LNF?

 

I posted a 'How-To' video in the how to section.

Here it is:

I wish i could have...... trying to get pic's in there is a real pain in the ass thou hehe. Around the seat area were really good .....that gray carbon is real thin ...almost like a light coat of sprayed primer . I was super happy when i first pulled the intake off

 

Hey both sound great! When I go nyirp anymore it's on wednesdays it's empty! Let me know if your really into the autoX, I would really love to give it a shot.

 

nice mine just got a headgasket on at 74k miles ive never sea foamed, just shell vpower and BG oil additive once every 30k it gets an induction clean, and the guys said no way this motor has 74k on it. my under side of valve cover look like new when i painted it

 

I gotta say, rukkee, that yours is BY FAR the cleanest head pic I've seen. Your runners are spotless compared to most of the pics I've seen. I've only done a couple of the Seafoam treatments, but I guess I'll step it up a little.

 

seafoam been using it on all of my cars and family cars every oil change since 2007, never let me down.

 

Thanks man ...... I caught a bit of crap back in the day when I was seafoaming my car with 5 and then 15K on it ......people thought I was nuts lol

 

Do we absolutely need to change the oil and spark plugs after a seafoam treatment via the intake manifold? I've heard that we needed to disconnect the catalytic converter as well which is insane since platinum is supposed to be self-cleaning, which got me thinking that new plugs probably aren't required.

How much seafoam do we need to use every 4k-5k miles? The whole can?

 

I have a second set of spark plugs to use when I Seafoam (original plugs that I pulled out.) I haven't seen any kind of buildup on them, but I've only done 2 Seafoam cleans. I do it before the oil change, but Seafoam says on the can that an oil change isn't required.

 

How did the spark plugs look after the seafoam treatment? I don't think the factory platinum/iridium plugs would foul that easily, but I just wanted to check.

 

I use a whole can..... i use half threw the intake and half in the gas tank for the injectors .

The 4th time i seafoamed my car I changed the plugs . (it wasnt cause the old ones looked bad) because people were always saying you needed to .......it hasnt hurt plugs , and I've seafoamed my car around 10 times .

 

When I seafomed mine I didnt change the spark plugs and had no issues. 1/3 in the gas tank, 1/3 in the oil and 1/3 in the intake. Thats how I did it. drove for about 100 miles then did an oil change

 

Nice man!!

I checked my intake valves when I installed my dual pass last winter.

They were spotless as well.

Although, I never use seafoam. Just 93 & race gas from time to time

 

I is gonna try to suckinify through the coldside vaccum port next time to clean throttle body along with intake mani
