Hi everyone,
After cleaning the throttle body and running some seafoam through the intake of my friends '05 Chevy Cobalt 2.2 I decided it was time to do some cleaning in the crankcase. The oil fill cap has white residue and the fill hole blows air out, rather than in (suction) as it should. I am thinking by using a cleaner in the oil it should smooth out the idle and restore suction to the oil fill hole. The car also needs a fuel filter as it continues to stall out even after a full can of seafoam thru the intake. This car does not have a pcv valve proper, so I can't change that like I wanted to. I am curious what would be better, seafoam or mmo in the crankcase? Maybe even Auto-RX if I can find where it is sold. My plan is to fully warm up the engine, then change the oil and filter (cheapo) add some seafoam or mmo to the crankcase then have her take it to her normal oil change place once it's dirty again for the "real" oil change that will be driven on. I'd like your opinions on seafoam vs MMO vs auto-rx and possibly even a good brand of oil to use in quick cleaning situations. I just don't want to run the cleaner with the filthy oil thats in there now in case it jams the filter up.
