KR Scanning and Seafoam
 

After a lengthy discussuon with Mr.Wren, We came to a conclusion that I might have excessive carbon built up in my cylinder head combustion chambers, and on the piston tops.
I bought a can.
I ran a KR scan BEFORE running the can through.
IAT temp 90 Farenhite, I made sure that baby was HEATSOAKED WELL.
Coolant temp 195-200F.
WOT in First gear it breifly hits 1 degree then hits 0.
In second gear it hits 1-2 breifly then hits 0
3rd gear pushing 85+mph WOT it starts to hit 3-4, climbing a hill like that I hit 5.
Ran the seafoam through, just a bit though, let it do its small smoke show, all that, then once it was running good again, i took it out.
Pretty much got the same results, however, safe to say, it cured about 1 degree.
I also discoverd a small exh leak, i over looked.
My EGR would mist some exhaust out under load, not much, enough i could see it, due to the exh color. Monday I will buy a new seal for it, and re do that, that could cause a small lean condition, however my 02 reads full rich at WOT..
Basically, i need to cure 4 degrees of KR

The smoke...it did get thicker than that, but, thats what it basically looks like

sounds nice I might try it but..
will seafoam strip rotor coating ive seen posts about it but never a strait answer?

I just ran seafoam on my riviera (gen 3 M62 with coated rotors) and I have not had a problem.

Billboost soaked some spare rotors in Seafoam and it had no effect (in my "Going to the track - Will seafoam strip rotors) in the Road and Track forum.

The smoke that came out of mine was insane after using half a can. I also found I had exhaust leaks. I could not tell where due to the MASSIVE amount of smoke that quickly filled the engine bay...

where can I buy this?
What is the exact name of it?
how do I use it?
does it have any risks?

Any number of autoparts stores, Wal-mart, etc
Seafoam is the name, the can has an old fashioned look to it, kinda hokey actually. It's sitting on the strut tower in the second pic, but the flash wiped out the label.
Pull a vacuum line off a tree and run a long line from the can to the vacuum port.
Could foul plugs, O2, and clog the cat with gunk, IMO, but I can't remember seeing any problems here.

well I have new plugs new O2 and a new cat :(
Think I should still use it it prolly needs it.

Given what I said, my plugs were fine afterwards, but my O2 was toast before hand.

my 02 will be changed here fairly soon again.
worthy product in my opinion.

im going to give it another shot this afternoon and let more run through it..might as well..
