A mechanic told me that in older cars, he would use transmission fluid, along with engine oil to flush out the engine. He said that the addictives that they put in the tranny fluid helped flush out the engine better. He said he would let it run for about 10 minutes.

Please tell me this is not a correct way to do this.

that is deffinately not a way that i have heard....but then again when it comes to flushing out my radiator.....i dont mess around with that...the cooling system is one thing i stay away from...seen too many things happen with it....so im not too aware of it being done that way tho either..

I've heard of a couple people talking about using mercon/dexron III as that... Sometimes people also use it to find any leaks because of how bad it smokes.

 

[jo_moped]

i have heard use dissel fuel

A cap full of Dexron Transmission fluid via the spark plug chamber.

It will smoke like hell , but its supposedly going to clean the chamber.

I've never tried it ......but it "supposedly" works ...

on each cyl?

never heard that but if you are wanting to flush the oil then gunk makes a product just for that that looks like atf fluid almost...run for 5 min then do you oil change...when your old oil's coming out it looks quite nasty compared to my normal oil change not sure if it's actually cleaning or if it's just the additive looking like crap??? Oh well figure it's not going to hurt.

i used the gunk engine cleaner. it worked pretty good on my engine. but then again my engine is clean in the inside. its just hard keeping the outside clean. im not sure if i have a small leak or i just did a bad job cleaning the block when i sprayed it with carb cleaner

 

[Tsunami_ZC]

on each cyl?

yes each cylinder ....

but be warned ......

if you did this ....i would recommend removing the cat ....

also be prepaired to at least install new spark plugs, and be careful with your O2 sensor.

 

[WildoutWhiteGSR]

Funny this sounds like a normal thing that mechanics do. Now what would be the proper way of doing it?

 

[greaseman]

just use Honda Top End Cleaner. also with this as style teg said to check your spark plugs and 02 sensor since all the carbon being extracted from the engine could foul your plugs and o2 sensor

 

[90_integraLS]

I used seafoam stuff work like a charm! white smoke everywhere there was some nice carbon deposits on the ground after it was done as well.

I keep my cars in good condition where I don't have to add anything weird to it. Flush and fill every 2 years keeps the coolant green and fresh looking.

 

[Hakamoto]

I don't think he meant the coolant system. I believe he was talking about carbon buildup. I personally use the cheap ATF fluid, because top end cleaner and seafoam work jus the same and I'm cheap. If you are doing it via a vacuum line there is a debate on where the best place to do it would be.

Here

Or here at the brake booster.

 

[Hakamoto]

I would also recommend that you do not stick the vacuum lines into the fluid of your choice, I would simply pour a little down into the line, wait, and repeat until you use about a 1/4-1/3 of a bottle of ATF, or 1/3 of a bottle of seafoam.

 

[Furious05]

Ok yea, I saw flush and thought coolant. Either way consistant oil changes and a fuel system cleaner every so ofent would prevent having to use such harsh treatment.

 

[jawz]

I hade tyied that once because of a mech told me of the properties in the atf fluid would clean the deposits better than any additive. But Let me tell you, my car smoked for about an hour and did not like it at all. Even when it was ddone it still had a little smoke come out every now and then. That turned me off big time and don't think I'll try that agian. Just like Furious said, fuel system cleaner and change your oil reg is better than dealing with all that smoke, Trust me!!
It was alot.

 

[WildoutWhiteGSR]

Alright good. I'm keeping up on my maintance with oil changes and fuel cleaner every other oil change.

Thanks for clearing that for me.

 

[95IntegraSE]

oil changes & fuel cleaner sounds alot better and less complicated.
