    im replacing mounts and cant get the last line off to lift this side of the engine?

    i did take the first 2 bolts off with impact wrench, but put them back when i couldnt get the third off. its a tight fit with pipe and 4th bolt is by hand

    picked up s wrench yesterday and sprayed down with wd40 and pb blaster

    what else can i do before calling someone with muscles? bad area for heat?

    there is always a way. human hands put it together, so human hands can take it apart, although not always easy. get some kind of a wrench or socket/breaker bar on the bolt and use a pry bar up along side the wrench to help pry against the wrench. it may take some imagination or other creative wrench manipulation. in this case no magic snake oil will make any difference in my opinion. i wouldn't use heat unless the bolts have threadlocker on them. sometimes i will take a cheap chinese wrench and heat and bend it to allow a better angle in restricted access areas

    A word of caution looking at those photos. Be careful using when regular sockets and accessories such as u-joints with an impact wrench. They could fly apart on you.with bad consequences.

    I've come to realize that having an assortment of extensions and wobblys long with Crows feet and long breaker bars is vital for hydraulic work.
