Seafoam? Yes or No

No. Because it doesn't do anything other than raise cetane levels and reduce the BTU's.It doesn't clean injectors and it doesn't improve fuel mileage so there is no use in using a product that is going to decrease performance and not clean injectors. The other problem is it does contains alcohol not good for the injection pumps and seals.

I tried a can as suggest by one of our vendors during my injector problems. Well I will say it does a wonderful job of masking the actual problem. The misfire came back as soon as the seafoam was consumed. As for cleaning the injectors never happened. As for reomving the injectors and soaking them in straight solvent... Never changed a thing... You literially have to scrub each and every piece of the injector to clean it. I will say it again...

"There is no cure in a can!"

If you wait until a symptom to arise then no a can, bottle, etc won't cure it.. at least not in one tank. When I got my truck it had a rough idle every now and then, usually after a long run the previous time the engine was running. Dealership duplicated it once, but never diagnosed it. I added "2um" filtration, and continued on my normal Amsoil Diesel Concentrate regime and haven't had the issue in 40K miles, but it took 20K miles for it to go completely away. So I think a regular injector cleaner will help keep it clean and reduce any deposits that may form, but it wont chip off a piece of nastiness overnight.
