polyurethane?

naw its like a polyprolene or something, its a weird type of "plastic" its not conventional plastic but it is in the plastic family, I forget the name. Polyurethane is softer and more flexible, this stuff is alot harder and more rigid

i used the seafoam on my engine today (m104). sucked in through vacuum line and let sit during my lunch for about 30 min. then went and drove on the highway. it smoked (white) like HELL for almost 10 minutes while driving. idle seems slightly smoother but don't really notice any big improvements yet. we will see with the gas milage though. however, i've heard that GM - top engine cleaner is far superior to seafoam.

when using the vacuum method...connect one side to the vacuum port and stick the other side in the can of seafoam. then take a pair of visegrips and squeeze the tubing enough so the engine barely sucks the fluid out (that way your engine will not hydrolock). basically the visegrips act a a check-valve!!!!

Ok I'll just say maybe i'm a dunce and its much more apparent to you all which is the vacuum line than it is to me. someone please just take a pic and post it. I already bought and used close to half of my can of seafoam. I'm just waiting to figure out which hose\ line to sip it in through.
