Seafoam wowza

[Darth Vader]

I just ran a 1/2 can of Seafoam through a vac line and wow, I have never, ever, in over 25 years of doing this, seen a car smoke that hard on cleanout. ...and I started doing this stuff back in the bad old days of the '70s, resurrecting junkyard-dog smog motors and stuff.

The car only has 20,000 miles on it, lol.

I now retract any statements I may have made, or even implied, that this motor doesn't gum up quick. I'll be firing Seafoam through this thing twice a year from now on.

Were you having issues with your engine that you needed to do a flush?

 

[GoFast]

did you change your plugs out after this?

 

[chief_wiggum]

did you change your plugs out after this?

I didn't after seafoaming mine. My MS3 smoked more after only 9K miles then my CR-V did with 75K miles.

 

[GoFast]

and no issues?

 

[chief_wiggum]

and no issues?

nope.

I did mine about 1000 miles ago when the MS3 had 16k miles on it. It smoked more than my 50k mile SRT-4 on its first seafoam. Also left the plugs in and it still runs fine.

This is after only 7,700 miles. 1/3 of the can in the vac line.

No issues. I just did a leakdown test and confirmed engine condition. I just saw a fair amount of buildup, for such low mileage, on the piston tops so, I thought I'd burn some of it off.

...and no, I didn't change the plugs either. They were new 500 km ago. The car seems to idle smoother now.

My smoke show was about 10X as bad as Sask's...it filled my entire driveway with clouds of white-blue smoke for about 20 minutes. I eventually drove it out and around a bit to finish it. Being catless I got the full effect, lol

Dang. I need to do mine next oil change. I'm @ 9700

 

[Darth Vader]

I think alot of my buildup might be due to the fact I live so close to my work that the motor can't even get it's water warm, much less it's oil so, it's running in pig-rich warmup alot of the time.

Sorry if this is a dumb questions but which vacuum hose should I run the sea foam through? Also, do you guys just to it at idle or rev it up?

The brake booster line... I could point it out on the engine... it's kinda hard to describe. The line is right next to the TMIC cover and brake/clutch fluid resevoir. I would just rev it a little to get it going again, then hold revs at 2,500 for a couple minutes and go for a drive afterwords.

Don't load the engine with this crap in it. Mine dieseled for a couple minutes after shutting off the ignition before grinding to a halt; not surpirising as Seafoam is mostly medical alcohol (isopropyl), light oil and white gas.

I used the BOV line because it's small. You don't want thie engine swallowing large quantities of liquid and that's an easy 1-man way to control it. I also dipped the line in and out of the liquid to ensure it went in a little at a time. The momentary vac leak is insignificant.

Then kill the engine and let it sit for a few minutes.

Then start her up and blip the throttle continuously between 1000 and 3000 rpm, until the smoke clears.

This is a solid safe practise similar to what I've used over many decades in performing this on many different types of cars. Good results, no negatives.

You can actually do this cleanout with plain water as well. We used to mist down carbs regularly in the bad old days. Seafoam is alot more effective though, especially for the initial heavy buildup.

Thanks Darth

Where exactly do you pour the seafoam in at? I'm not exactly sure where the lines are and I thought you put some in the gas tank?

1/3 Gas Tank
1/3 Crankcase
1/3 Brake Booster (2 people req.) or vac line from BPV

 

[H3br3w_Ham3r]

or vac line from BPV

Is this the smaller of the two hoses I'm assuming?

Yep. Don't wanna have that thing in your turbo, that's for sure. (2thumbs)

Or you can make your engine sputter and almost die 7 times like I did!
