Two ways I know to loosen them are penetrating oil or heat. I just took a bunch out of the rear bumper and hitch of mine without any broken by heating the bolt heads until they just started to glow red with acetylene then letting them cool for a few minutes then taking them out.MEphenSean said:This may be a long shot, but does anyone happen to know off hand what gasket I need between the exhaust manifold and the pipe that leads toward the cat? It's a 1995 Trooper Limited, DOHC.
There is definitely a leak there and has been for a year. Not sure if there is even a gasket there at all, but I will need to pass emissions testing in about a month. I called a few local exhaust shops and none of them want to touch it. One guy took a quick look and said the bolts at that flange will be a problem, and one my be cross-threaded because it looks crooked. He said if a bolt breaks there, he'd need to pull the manifold and would be charging me big $$$. And the usual parts suspects can't seem to tell me what size gasket I need.
Anyone know the measurements, and whether it is of the type that surrounds the bolt holes or one that just slips in around the pipe? Got any tips for getting the bolts off? The location of the darn things makes it tough - really tight working quarters, which is why I tried to take it somewhere before trying on my own. Gotta do something though, this is my daily driver at the moment, and needs to pass testing.
