Hi guys....

Ben here - i have a bone stock EG5 with a ZC dohc engine as stock ( lucky us here in australai ).....which is runnign tired to say the least. I took a peek down the spark plug holes last change with a torch - and gosh is it black n slimy in there lol.

Anyway , i was thinkign of runnign a seafoam type product to help clean all this carbon crap out....ive heard its a good thing on our old engines. ( mines sittign at 103,000miles)


Any valid experience with it guys ? Does it really clean out all the gunk + really revitalises the engine ? any other pros n cons ?

Oh...where can i get it n OZ ? lol . . . thanks, !

 

bad *** an ausi!!!

From what i understand your CRXs are our Del Sols...either way i've heard great things about sea foam. But it has to be done perfect or you'll lock your engine or something like that.

 

I've only used sea foam in my jet ski, it works great, just pour it in the gas. Another method would be to use water. Water? Yes, WATER!! Take the tubing off your throttlebody, find a spray bottle, fill it with water and set it on a HEAVY mist, start your car, reach down and rev your car up to 2k, start spraying the water into the intake manifold, spay it fast so that the car's rpm start to drop a little, do this for about five minutes. Nomatter how hot you get water, it will not burn!!! The water actually grabs onto the carbon and pulls it loose. I'm not bullshitting you. If the car starts to, die stop spraying the water. You do not want it to die or your might cause it to hydro lock. If it does die, take all the spark plugs out, and crank the motor over. Then put the spark plugs back into the motor and restart. The instructor at Foothills Tehc. Inst., where I got my Automotive Tech. degree, Bill Sutterfield, taught me that. Yes, it works. Try it and let me know what you think.

And good luck

I have used Seafoam in most of my cars and I also use it in my small engines like lawnmowers and stuff. Works great. I only have used it in the gas tank.

...great knowledge there...ive heard this freebie cleaner before - altho it STILL sounds alittle dodgy to myself lol.

Is it realyl as simple as "removing throttle pipe, spraying constant for abit then thats it" ? How do i fidn out if this realyl has worked ( IE proof in oil or excess smoke or even better running etc)

Can soem one please back up this theory before i ruin my engine with a silly mistake ?

Thanks !

 

I sea foamed my Civic and it worked fine. I had my intake manifold off last week and it looked completely clean inside as well as the intake ports on the head! The pistons looked decent as well when I pulled the head off. This was on my DPFI setup.

 

Even easier, use your brake booster vacuum line, attached to a spray bottle, with a valve on it(you can make these for like 10 bux, and they can be resused). I've done the Honda Top Engine cleaner using this and let me say...works VERY well. You'll see tons of white smoke out your tail pipe, and if your car is OBD1 or 2, it might throw a CEL. If you want to try it PM me, I'll give more detailed instructions.

 

do it, sea foam worked for me!!

 

i seafoamed my dohc zc(was perfect beforehand) and it never stopped smoking, i think the valve guides are bad.... i won't ever use it again

 

I used seafoam on my mini me and it worked great.. my motor's idle was real smooth after.

My opinion on SeaFoam = good stuff

there is no way you are going to hydro lock your engine by spraying/misting water into it.

 

if you can't find seafoam, use ATF.

careful tho, you don't want to remove all the carbon on some older engines, since the carbon is what keeps the compression #s up when they get old.

 

Seafoam worked wonders in my DOHC ZC. Also worked wonders in my Crown Vic I had.

 

Used it on a 85 hp johnson outboard.... Works like a charm...

 

where can i get this seafoam? ive heard of it back int he day when i was cleaning out my throttle body on a truck i had, and we couldnt find it at any of the auto parts stores around here.

 

The stuff works great! used it a lot at the dealership. I'd recommend the gas tank method. Well worth the money if you are debating if you should spend the cash.

Best of luck

 

How is sea foam used? other than simply adding it to the gas tank?

 

I put 1/3 of a can in the brake booster, 1/3 in the crank case, and 1/3 in the gas tank. While the engine was running. Started to spew deep black smoke for about 2 minutes, took it out for a test drive. I got a 4-6 mpg increase :D. Make sure you get new plugs after, or atleast clean yours. - Darrell

whats the brake booster? and how do you put it in the crank case?

 

The brake booster is the thing right by the master cylinder with a vacuum hose running to it from the intake manifold. The big black round thing on the firewall.

You put it into the crankcase by pouring it into the "add oil" hole on top of the engine. That is the crankcase.
