View Full Version : Seafoam caused grinding noise

Just added 6.75 oz (200ml) seafoam to my oil, now it makes this horrible grinding noise.... the hell?

Was that too much or something?

edit: oh heh this is my first post ... Hi!

Just added as in it started making the sound as soon as you did it?

oh, and

Started after the car ran for 10 seconds or so, once the seafoam mixed in.
Guess I gotta get an oil change like right now if I can find anyone to do it >.< 4:30 already. =/

No horrible unlubircated sounding noises anywhere in that video =P. What I used was slightly more than 1/3 can, the seafoam site said 1.5 oz per liter of oil. Haven't done the vac line or gas.

Only thing I can think of was it was too much and the oil thinned out.

Comes from the belt side pulleys I think, otherwise the engine sounds nice....drove up and down the street it doesn't seem to want to go away. boo @ fail =(

Was just wondering if anyone had a similar experience.

I have done this with two different vehicles and never had anything happen like what you are describing.

I have used Seafoam in the crankcase on numerous vehicles with no problems. I even used it on my wifes Alero with 110,000 miles. I'm guessing it's coincidental, unless you're low on oil to begin with.

Oil is pretty full, I'm afraid of overfilling it adding more.

New attachment, old one is bad I never checked it. It's crazy!

You sure you didn't drop anything into the crankcase while pouring the Seafoam in?

10-26-2009, 04:00 PM
Yeah I just poured it in from the beaker I used to measure it.

10-26-2009, 04:49 PM
Yeah, never heard of this problem before. Used it on my grand prix once without problems.

Heh if nobody has heard of anything like this maybe it is unrelated and I just happened to notice it now. Bad bearing or something.

Drove a mile or so and it died out some, disappeared entirely messing with it in a parking lot but came back a little once I got home. Depending on how it is tomorrow morning I might change the oil.

AC clutch? *shrug

when i did my seafoam in my car i used it in the fuel tank, the crank case, and in a vaccume line, i had no problems with the car. the car ran beautiful. i used it right after i dropped the new motor in the car. its really helped make that motor run. but i never heard of anyone haveing any problems with it. i recommend it to everyone who wants run a good cleaner through there vehicle.

Been using Seafoam for a lot of years now in the GA. I put 8 oz. in the crankcase about 4 days before I get an oil change and pour the other 8 oz. in the gas tank with about 8 gallons of fuel (says to use 1 oz. for every gallon of fuel). I've never had problems and it's always done amazing things for my 11 year old engine. Might be a localized problem. Change your oil to see if the Seafoam didn't just free some contaminants up.

sounds just like your A/C clutch to me. Try turning on your A/C for a few mins then listen for the sound. If the sounds gone when the A/C is on then its def. your clutch or a bearing for it.

Yeah whatever it was wasn't the seafoam, just a weird coincidence.

After about 50 miles I did the seafoam in the valve line on the front of the engine and changed the oil. Didn't see the brake booster line til after I had done it =P
Didn't get much of a smoke show but the engine seems a little happier now..hopefully mileage improves =D.

Might have been the AC I used it for the first time in months that day but whatever it was is so much gone now it would be impossible to try and figure it out for sure.

Scared the hell out of me though ... HORRIBLE sound. >.<

the GA didn't smoke much either...the truck with 130K on it on the other
