Top End Cleaner/Additive?
With all this talk about leakage thru the valves when doing compression test, does anyone know of any effective additive/cleaner that can be used to clean the valves without opening up the top end?
Does using synthetic oil help? I know synthetic oil can be a good cleaner. But whether it reaches the top end.........?

Decarbonizers
Thanks, Roy....
I've been checking around and found some stuff. There's probably been new developments since 2001 when the discussion on x-66 started. How about these products? http://www.neptuneproducts.co.nz/shop/Products/FTC+Catalytic+Engine+Decarboniser.html http://www.bgprod.com/blendr/sayGoodbye.html

Hmmm
My experience is that BG does work, at least once.
It is still cheaper to fix the problems that can cause carbon buildup before it is an issue. |

Doesn't some carbon build up ocur no matter what you do? I've been using BG gas additive which seems to work well. All of the mechanics I know seem to think it works much better than the off-the-shelf stuff.

I've used Techron before, but lately I've been using BG. Several mechanics I've spoken to told me that the BG additives and cleaners have a solvent in them, as opposed to just detergents. They said the BG was more effective. I like it. It seems to work well for me. I think it's only sold through mechanics, though.

Gumout Regane and Chevron Techron works pretty good in removing carbon deposits apart from a professional carbon cleaning job. http://www.gumout.com/products.asp?products=1_4

BG44K is the best and you can buy it on ebay all day long. You're after the black cans with the gold lettering. Pour a can in the gas tank and enjoy.
If you want to really see an improvement, buy their 3 can induction service kit. One can goes in the tank, one aerosol can for blasting out the throttle body and intake opening that you can get to, and then one can that you let the engine suck in and burn while at a hight idle through a vacuum port on the intake somewhere (your choice). Once the engine has sucked up the can, you shut it down for 15min. Then go for a good drive. You'll be amazed at how much better it starts, idles and runs. Then, once the can you put in the tank has had a chance to clean the injectors, you'll notice more improvement.

i heard seafoam works great .. synthetic oil is awesome too ...
and i know u dont wanna take the top end off but i highly reccomend it .. not hard at all to pull head off and to get it pressured tested, machined and valve job only runs about 240.00 ..add another 130 for gasket set .. i just completed mine and man what a difference Last edited by xtreme barton; 10-15-2007 at 08:50 PM. |

I've used seafoam. It seemed to have worked well on the 280SEL.

The valves of the cylinder you are working on MUST be CLOSED, to keep the junk out = you will need to crank the engine by hand. This is the perfect time to adjust your valves. |
