Question about 1998 Chevrolet Chevrolet silverado
Exhaust is one of the hardest things to replace without breaking bolts So the 1 st and up most thing is lubrication get a good penetrating oil liquid wrench,WD40,LPS whatever your parts guy suggests buy the large can now spray ever bolt you can see even the exhaust pipe flange nuts run until hot spray again let cool down over night spray again now you are ready to try to get the bolts out. place a socket with a ratchet 3/8 the handle should be at least 8 inches just slowly pull in a counter clock wise motion until you have reached about 45 lbs torque if bolt has not moved then stop try to tighten bolt a little then repeat on the real stubborn one use a long round steel rod go thru fender well and hit the bolt head really hard this will shock the threads to allow easier removal after all are removed then throw all those bolts away and install new ones with the new manifold and gasket..

SOURCE: exhaust leak
they don't go into the water jacket, but be careful not to drill any deeper than the bottom of the bolt hole or you can go through to the water jacket, a piece of rubber vacuum hose over the drill works well to limit the drill depth.

bank 1 is the drivers side bank, so b1s1 would be the drivers side closest to the engine. if the truck is equipped with several 02 sensors then bank 2 or b2s1 would be passenger side closest to the engine. those are called upstream o2 sensors and the others downstream b1s2 and b1s2 b= bank 1= drivers side s=sensor 2=downstream. hope this helps.

buy some engine oil dye at any auto parts store
a uv lamp will be needed to use to locate the leak
this works best with newer cars and so many things in the way
