2001 Dodge Caravan needs a new upstream oxygen sensor
. Rusted so bad I can't get it out of manifold. Heated with a torch and mangled it. Tried to pull the manifold, but 4 of the bolts to the head are rusted such that I can't get a socket to turn them. So now I need to pull or drop the engine to get a straight shot at the sensor (stub) or the manifold bolts if I need to replace the manifold.
JA: Have you located all of the vehicle's oxygen sensors? Are the wires leading to and from each intact and in good shape?
Customer: Yes and yes.
JA: Are you fixing your Caravan yourself? What have you tried so far?
Customer: Yes. I got a socket onto the upstream sensor, couldn't turn it. Heated it bright red with the oxy-acetylene torch and tried again with the impact wrench. Mangled the sensor pretty bad, won't turn, no good access. Manifold won't come off due to badly rusted bolt heads, so I need to get the engine out far enough to work on these problems. There is only 3 inches of space there.
JA: Anything else you want the mechanic to know before I connect you?
Customer: I'd like to remove the engine only, without the transaxle if at all possible.
