Anyone notice this as well doing a top engine clean?

I recently did a sea foam treatment thru the vacuum hose from the power booster into the intake to clean carbon build up inside the head (had a misfire cylinder one) trust me I did everything as far as maintenance to clear the code. Anyhow its been about a couple months but I still notice a strong odor of seafoam inside the car, is this common and has anyone that has performed this experienced the same results. (btw, this did clear my code on two occassions as I once did it about three months before the second time). I think after the first treatment it loosened up alot of carbon and build up heavier around the valve and caused another valve seating problem. At best guess as I haven't had the head taken off yet. Both times the misfire code was corrected by the seafoam treatment.

Almost seems like the smell is coming from the air vents while the heater is running. (can't be sure though)
Thanks

I can't remember what sea foam smells like, are you sure it isn't the smell of gasoline? I had that same problem and it was a bad fuel injector.

No I'm sure as I just replaced my fuel injector gaskets as that was part of the maintenance trying to clear the misfire code. I had the injectors cleaned and inspected. While removing one of the injectors the o ring was torn and I just replaced all o rings and gaskets cause I didn't notice the tear and had a leak and the fuel smell was horrible.

No this smell is very different, seafoam does not smell like 93 octane gasoline at all.

Re: Anyone notice this as well doing a top engine clean?

I might have an answer to my own question again. Does anyone know if going thru intake like I did thru the vacuum line from the power booster if the seafoam would make it into the coolant system? As it might be that since some seafoam might have made it into the coolant system and once the heat is on it makes its way thru the heater core and that is where the smell is generated.

I've done seafoam on my own..x2

just did it last weekend also

crankcase,fuel tank, and vaccum line..

The seafoam does a great job of cleaing a clogged CAT. mine gets clogged sometimes, and throws an o2 code.. but thats the only code i've ever gotten..

the only thing i could think of would be.. are you using the "re-circualte" air button on your heater unit, that recirculates the inside air of your car to heat it, or are you pulling outside air?

if you're pulling out side air, you are getting everything from the outside including from the engine bay..so all the smells outside go into your car... sea foam is never fully burned out of the car because it is a petrolieum based detergent.. so technically to keep things lubricated, it can linger for a bit, thats why the treatment continues to work for a few months even after the white smoke is gone.. so seafoam could potentially be built up somewhere and still be burning off.. i highly doubt it went into the coolant!

hope this helps

ah thats it then as I bring in the air from outside, cause during these months my own breath inside the car is enough moisture to fog up the windows. Thanks man.

That was it I started smelling the fumes again on the way to school tonight, so I set it to re circulate and the smell went away.

Thanks.

seafoam is a solvent. when was the last time you changed your oil since you introduced it to your motor? who says it couldnt get into your coolant if he has sealing issues by the cylinders

Re: Anyone notice this as well doing a top engine clean?

Seafoam is great. I use it and it does really help a lot. hands down i love it but you have to be carefull how often you use it. it can dry out your hoses and make them brittle if you use it too much. this is just because it is a solvent and solvents do this if used repetitively. not saying it is bad. just monitor how much it is used. noone likes to replace gaskets lol

just my 2 cents

Changed this past Wednesday before taking a trip to Wintergreen Ski Resort. So it's been changed twice since the last seafoam treatment. I change the oil every three month whether it hits 3000 or not. Car isn't driven that much.

Re: Anyone notice this as well doing a top engine clean?

I think about three to four months went by between the two times I introduced seafoam. My compression test were

1 198 lbs
2 210 lbs
3 210 lbs
4 210 lbs

I believe 1 may have been a bit low as one of the valves didn't seem to be seating all the way so I thought that might contribute to the being lower than the other cylinders, this test was done before the first seafoam treatment. I really need to perform another one after the treatment so I see if there was in improvement.

Plus the smell is very strong at times I almost think I may have a small fuel leak near the fuel rail, may have another torn o ring on one of the injectors.
