Default Subaru Top Engine Cleaner or Seafoam use questions

Hello,

My car is knock/ping prone and I was told to 'seafoam' my engine to get rid of carbon deposits that are most likely the cause of my inexplicable detonation. I was a little leary of doing this to my 7500mile engine, but I saw this bottle of Subaru Top Engine Cleaner at the dealer when I went in for my 7500 m service, and it's basically the same as Seafoam - with the same directions for use. A tech told me that's a common thing and it would be a good idea to use it.

Anyone done this? Anyone tried Seafoam on a WRX? Is there any obvious things I should/shouldn't do with this - or anything specific to the WRX I should know before trying?

Please let me know. If anyone has used either product in a WRX and has some info about before/after, please let me know. Just want my car to run right, and I don't want to do anything wrong to it..

Thanks!

-Jacob

We were just talking about seafoam last night, what a coincidence. Austin uses it.

Default Awesome..

Not sure who Austin is.. Can you put him in touch with me or show him the thread? I would appreciate some advice..

BTW - I did this with the Subaru bottle, and the car seems to run much better so.. I think this may be a good thing. Still would love to hear something from someone who has done this tho..

Thanks!!

i thought cleaning out carbon deposits was done on much older cars. you're car seems to new to have any noticable amount of carbon deposit

so how much does this bottle cost and how do u go bout using it?

Our cars run very rich, carbon builds up quick.

Anyone have any experience doing this?

I picked up some GM Top Engine cleaner (same stuff) and I was wondering if I should pour it directly in to the Throttle Body or if I should find a vacuum line to siphon it out of the bottle....

I've used Seafoam on numerous cars and it has made a significant difference on all of them, its a great product. Mopar Combustion Chamber cleaner (MCC) is similar and is what all the DSM guys use, also with great success.

Using a good catch can setup will avoid this BTW.

I usually suck up the seafoam through the divertor hose off the bipass valve. Its the same line you would use for the boost gauge.

Can I just unplug the BPV line and pour in small amounts of Seafoam? (Not sure if allowing the car to run with the BPV line unattached can hurt the car).

Wait until your next oil change. If you want, put half the bottle in the gas tank and maybe the other half suck it up into the vacuum hose of the bypass valve it works great

if you've got cats it might not be a bad idea to disconnect them. but seeing how you've only got 7500 miles on the car i wouldn't bother. also seafoam while the engine is warm/hot

Yes, just pulled the line off the BPV and sucked it in there. Just make sure to only injest very small amounts at a time...start with litterally a drop and increase a bit as the car allows. The car will stumble, then recover, then you add a bit more. It is a very slow process, but you only use 1/3 to 1/4 of the can IIRC. Just follow the instructions on the back of the can, remembering to add very small amounts at a time (I think I may have used the cap as my sucking container).

Another thing...the car will smoke (out of the tailpipe) like your garage is on fire, no joke. There are stories of neigbors calling the fire department during seafoam treatments. Keep that in mind; maybe do it at night.

Yea, I ended up doing it and it was great! Smoked like crazy and I think the butt dyno reported more throttle response afterwards

Anyone try putting any of this stuff into the turbo inlet hose to help clean the hose and the turbo compressor wheel by change? I've heard of some doing that, I just wasn't sure where to put it or anything.
