GM Top Engine Cleaner

[Durien512]

what are your thoughts on it?? have you used it??
i am thinking of gettting some..

there are 2 types... spray or can.... why would i pick one over the other?

[C-B64]

I used the can one saturday. I'll tell ya I do know it does something, lol. Because my car smoked for 5 minutes straight lol. It does get the carbon build up out, lol. We put it in, and let it set about an hour, and then started it up, and i let it warm up, and then started reving some and the white smoke rolled, lol. The I changed the oil, it will finally quit smoking. lol

I dunno about the spray, but the can is not hard at all to do.......

I also used the can...went in easy through the PCV pipe.

I used the spray can, and like was said above, my car smoked for several minutes. Cleaned out the oil that was in the intake manifold though :cool: .

Im pretty sure the spray and the liquid is the EXACT same stuff, so in theory, it should work the same.

For what its worth, you can save a few bucks and go to NAPA and buy a product called Seafoam. Its the same thing as the GM stuff.

I'm due for an oil change soon, I think I might go ahead and do this

[Blacker]

Get two cans and change the oil a couple of days later.

[killer01ws6]

Would you do this right before of right after a cam swap?

[Blacker]

It should not really matter. Whatever is conveinient for you.

I used a can of Seafoam the other day and it works great also. The dealers here in Ca. aren't allowed to order Top Engine Cleaner any longer due to new environmental regulations. :mad:

Might look into the seafoam stuff as well. How many miles before you should do it? I have 52k right now, never been done as far as I know!!

I usually run a can through every other oil change (6,000 miles). This might be "overkill" but with the crappy PCV system, we get a lot of oil in the intake which ends up in the combustion chamber.

Have you considered the catch can mod? I has helped trap any oil from getting into the intake on my car.

I switched to the new PCV valve but I still get some oil in the intake. A catch can is next on my list of things to do. :D

[FirehawkNS]

Mine too!!

[INDA10Z]

Seafoam is the same stuff and its only 4 bux at Checker/autozone

[lucky_topher]

i did mine right before an oil change.. and right after i did the catchcan... that way i prevent future issues (as best as possible of course)... 2 cans, in through the PCV into the intake.. easy as hell.. let it sit overnight then the next morning i turned the weather from sunny to partly cloudy ;)
