273 hp valve seals replaced before after video.

SeaFoam is the best stuff out there for things like that. I've used it many, many times with great results...

There is a big difference in the before/after video's. Good luck!

Is that smoke or steam on the second video?

still a little blue smoke yet.. it's not all gone yet . but they are looening up .

probally going to give another dose of seafoam yet , then start running some rotella T6 oil .

but overall sooooooo much better !:happy2:
