Anyone try to use a Seafoam on your car?

I'm almost too scared to try out the seafoam but it looks fun to try....

I took an advance engine performance class in 1990's at General Motors training center in Burbank next to Hollywood, Ca. The class has a famous instructor. Who? Ellen Smith, top female GM technician in USA. She addresses about her mechanic background. And she demo how to diagnose the driveability problems and use top engine cleaner similar to Seaform to demo me along with technicians. She was good with it and no fear about the clouds. I never forget her face.

You can try it yourself if you are good with hands and safety knowledge.

I remembered you told me that one of your coworker pour the AFT in the diesel's fuel filter.

AFT? ATF .... Before install a new fuel filter, fill a new fuel filter with fresh ATF to prime fuel into the injection pump for fast starting. I learned it from a diesel mechanic. Hey, did your instructor do that before?
 
Guys if you want to clean your engine well, buy 3 bottles of oil 2 cheap and one top rate stuff and three filters, now proceed to do 3 oil changes and you will clean your engine out

Do you know what carbon build up look like?

You don't need seafoam. Just pour BG44K or Chevron Techron into your gas tank every 3-5000 miles. that's easy

Will they remove large sludge buildup? My answer is no. Only clean thin sludge buildup. They can vanish piston rings, sticky valves and valve hydraulic lifters to remove carbons and restore good lubricate the moving parts.

The 1st pix on top .... Looks like exhaust valves in port to me. Most carbon buildup inside the valves are intake valves cuz the intake valves are about to open and suck incoming air/fuel mixture and oil from worn valve guides or bad seals into combustion chambers.

Its your choice to poor a solvent into your engine but what if chunks of carbon fall into the piston chamber and scratch the bore, thats a risk i would never take. I would rather stick to putting oil in my engine.

Chunks of carbon will not scratch the cylinder walls and always purge from exhaust ports, sometime circle back to EGR passages. Scratched bores (scored bores) are caused overheat, dirty oil or improper oil and dirty air induct (means air filter in housing, missing or deleted or improper filter seating in the housing). No worry about chunks of carbon.

Yes, it is intake valve and exhaust valve.

I am not sure the 2nd pix shows burnt intake valves in black combustion chamber. Just a thought.
 
I have a can of a several months old seafoam that I had laying around in the broken minivan. I have 129k miles on my Honda but should I use up the seafoam?

Use up. If leave opened cap and store for long time, discard it but you can use it for engine flush before oil/filter change or top engine cleaner only. I have 3 GM top engine cleaner cans, dated back in 1990's, never open them.

I was thinking about putting it in the gas tank to clean the injectors. It does have a high percentage of alcohol content, so worry about it eating up the rubber seals and the gaskets, etc.

IF seafoam does what it says it does im all for it, im just worried about causing more problems.

If your car can take fuel with ethanol in it it should be a problem, check with the manufacturer.
