I read on superhonda.com few years ago that it is not recommanded to use Seafoam on a engine that as more than 93-94 000 miles on it (150 000km). My VX have 135 milles on it, and its the reason why I didn't do it (got the car at 94 000miles but didn't think about doing it at the time.
So would you use in on a 135k miles engine, I will probably go to a honda dealer to do it for me (so doint a de-carbonizing, maybe not using seafoam, don't know,,,)
My motor has around 130k on it, and it loved it! haha
On the never-ending quest for better gas mileage...
My motor isn't in the greatest health. There's nothing majorly wrong with it. The valve stem seals are a little worn and allow some oil to be burned, as well as the piston rings are wearing too. Last compression check (done two or so months ago) yielded a solid 200-196psi across the board though.
BIBI - does your VX idle that high when you have the climate control fan off along with the lights off and your foot off of the brake?
Just remove the top tube (the one that goes back towards the fender in front of the airbox) then you can see where you can attach the dryer hose and just run it to the manifold. I used a length of mechanic's wire to hold the dryer hose to the upper radiator hose for support.
i just seafoamed my chevette and the awesome smoky cloud of doom. i dunno if it helps but ive had it in the crankcase for the last 300 miles and that oil came out BLACK...put exactly 4 qts in and right up to the full line. we shall see if it helps fe any
