I actually have 2 cars, a 95 civic dx with 123k and a 91 nissan 240sx with 160k. Recently the civic throttle response is poor so I'm thinking about using some sea foam (vacuum lines/crank) and deep creep on the TB. I heard alot of good things about it. However, my 240 has a minor oil leak. Would you reccomend still doing the sea foam on this engine, would it help or harm the oil leak. Also, what other products out there could help me with the leak. thanks guys

 

i would do it its best to change you oil afterwards anyway b/c all the crap will end up in there. but i would still do it. i did and it makes a noticeable diff

 

I sea-foamed my 186,000 mile Nissan Pathfinder and it has a slight oil leak, and it runs much better now.

 

I SeaFoamed my 138k Civic. I guess it worked, but I doubt I had any carbon build-up on my piston tops, no white smoke came out of my exhaust, AT ALL.

There is another user on here, he SeaFoamed his Civic at like 210k+. Worked great.

 

Someone had mentioned the fact that in a higher mileage engine, carbon deposits actually help maintain compression. If this is true, by removing them I will lower my compression and make the oil leak worse? This just doesn't make sense to me, clean your engine out and f it up.

 

There seem to be a lot of mixed feelings about Seafoam. I've used it and it was ok, not spectacular, but I don't have but 84,xxx miles. You just have to decide if you wanna try it or not.

 

I've used this stuff on many highmileage cars and even 2 cycle engines that were 10+ years old. I found that on the 2 cycle engines it actually increases the compression of the engine by freeing up the rings which were not fully expanding due to years of carbon build up and varnish from old gas.
On your car engines the carbon build up on your pistons that increases your compression, a very minimal amount I might add, will not be missed. When sea foam is used proplery it will remove the varnish and carbon deposits causing your valves to not seat properly and free up any rings that are not expanding/contracting properly, this will actually increase your compression giving you more performance and fuel economy.

 

I think seafoam is too harsh. I have used a product called Auto RX and it's been great for me. It does the same thing as seafoam, but it's not as harsh and it won't ruin your plugs or O2 sensor. http://www.auto-rx.com

 

thanks alot guys for the help and the quick response. Here's another question while we're on the topic. It has been suggested that you remove your 02 sensor when you're doing this procedure in order to protect it from the burning carbon deposits. My question is once you remove the 02 sensor from the side of the exhaust manifold, won't the smoke pour out of that hole and totally smoke you out when you're trying to feed the seafoam into the vacuum line? I just don't feel like replacing the 02 sensor, its workin fine for me. thanks

 

it says on the can O2 safe on the can and if used as directed it will not cause any sensor damage and will not be too harsh. We even use this on Walker mowers with kohler 26 hp efi engines which have o2 sensors that are more sensitive than anything I have ever seen. This stuff is only harmul if you swallow it or get it in your eyes.
and this stuff will not harm your plugs, I have used it many times and have never seen any visual damage, just cleans the carbon deposits off.

 

I am planning to change out my plugs anyway, so thats not a problem. I've been doing alot of research on this, and Auto-RX seems to be a popular one too, and people seem to be saying its less harsh on the motor. The problem is I'm not sure if they are real stories, or people who are endorsed by auto-rx.

 

I've never heard of it, I'm a sea foam dealer. Its been around since the 40's so its done something well to hang around this long.

 

you're a seafoam dealer thats great. no wonder you are endorsing their product. anyone out there not being paid to represent a product have an opinion?

 

Seafoamed mine for the first time at 180,000 - no problems!!

sea foam killed my o2 sensor but other than that it works.

 

I used seafoam on my 138,000 mile civic and it worked great. I noticed a better idle, smoother acceleration, and MUCH better gas mileage. I got almost 40 more miles out of a tank after using seafoam, with mixed highway and city driving. I say go for it.

 

call up a compnay that makes after-market headers for civics and ask them if they can send you 02 bung plugs. when i bought my headers both bungs were plugged. that would solve your getting smoked out problem.

 

has anyone used seafoam on a boosted engine? I have a D16Y8 motor that is running that has been happily boosted for almost 2 years @ 9 psi. would the seafoam be a big risk to take?

Yo green27 - People like dohcdelsol93 have posted good answers to Seafoam threads 100 times over.......why don't you try a search ?

 

there was a sea-foam thread that was like some ridiculous # of pages where i know of at least one user stating he used it on his turbo set-up and everything worked fine and he was happy. i would look for it in SEARCH.

 

using seafoam in a turbo application would work just the same, I would just limit treatment of the crankcase to a few min. rather than a few miles to prevent any bearing damage to the turbo due to oil thinning.

 

sea foam is good ****! i used some tonite on my gsr w/ 180,000 miles. you could really feel a difference, it seems like a new car

i used it on my boosted y7, didnt have any problems. i only left if in the oil for a few minutes, and i also used it thru the intake.

 

your never supposed to use engine cleaners on boosted engines

carbon deposits from your engine that find theyre way through the exhaust will plug up and blow your turbo

oh yeah.. and anything in the oil can mess your turbo up good too

so engine cleaning agents + turbo == a big no no
