Chevydog89 Posted May 22, 2012 Share Posted May 22, 2012 What's the best way to use Seafoam in a Loyale? I often use it in my 94 Grand Am and suck it through a vacuum line, and rarely put it in the gas tank. The Loyale has 108,000 miles on it it's 2WD/AT if that matters. I don't know if it would be best to suck it through a vacuum line to clean out the top end a little bit, or just go ahead and use it in the gas tank. I know both will clean 2 different areas. And I also don't know what vacuum hose to use on the Loyale if I went that way. Any suggestions would be great. Quote Link to comment Share on other sites More sharing options...
kabarakh Posted May 22, 2012 Share Posted May 22, 2012 I unplug the pcv lline at it's "t" fitting and pour it in there, so it passes through the pvc valve into the manifold. I pour it rather then letting the hose suck it out so I can control the flow rate. Some people use the brake booster line too. Quote Link to comment Share on other sites More sharing options...
MilesFox Posted May 22, 2012 Share Posted May 22, 2012 run the engine to operating temp. suck up 2/3 of the can until the engine chokes out. pur some in the idle air control valve and fill up the hose, cycle the key (run, not start) so it opens, do this several times. after sitting for at least 15 minutws, more is better, run the bejeezus out of it. dump the remaining can in either the fuel, or into the oil just before an oil change.

Stubies Subie Posted May 22, 2012 Share Posted May 22, 2012 I seafoamed my 91 loyale, I used about 5 cans of the stuff, I soaked the cylinders with some, ran some through the vacuum lines, ran some in the fuel tank and in the oil, all i can tell ya is that when I was done, it was like driving a whole nother car.

Chevydog89 Posted May 22, 2012 Author Share Posted May 22, 2012 Haha, I don't know if I wanna spend that money on 5 cans But if you guys know of pics that show which vacuum lines to use, that would be great. I'm still not familiar enough with the car to know what is where. Quote Link to comment Share on other sites More sharing options...
xbeerd Posted May 22, 2012 Share Posted May 22, 2012 i find that tractor supply stores carry the seafoam about $3 less per can than places like autozone/advance/oreily etc. might call around. 5 cans might be a bit much, LOL> but hell, who am i to say whats right and wrong.

Hey Miles just curious if you could show a pic of that idle air control valve. Quote Link to comment Share on other sites More sharing options...
Rick James Posted May 23, 2012 Share Posted May 23, 2012 (edited) my understanding is that it's the cylinder that these pics focus on.. .well the one with the rust and the wire going to it Edited May 23, 2012 by Rick James Quote Link to comment Share on other sites More sharing options...
