WILL85IROC

im trying to change the oil in my car, its a 85 iroc, 5.0 tpi... the drain plug bolt is stuck and wont turn.... i tired to turn it for a bit but then stopped because i dont know what damage i could to the pan if i really force... in the mean time i hosed it down with some wd40 and will try again in about an hr... if it doesnt work how do i drain the old oil so i can change it???

there is one way to drain the oil on a sb Chevy and its threw that stuck drain plug if the oil pans not super rusty get a long backer bar on it and a six point socket and brake it lose other then that there's not much you and do,PB blaster works well for stuck bolts

I would stay away form heating it at all so you don't burn up oil in it and get stuck with sludge

either the plug has to come out, or the pan has to be dropped - no other alternatives.

i second the breaker bar
i use the bar from my jack. assuming you have one use it or a piece of pipe,slip it over ratchet and use it as a cheater bar ive done this neumorous times,with oil drain bolts,flywheels,and reinstalling harmonic balancers(works great)
