hey guys, i have a jetta that just came into the garage the other day that dropped a valve on number 4. tore the head off and found piston number 4 mangled and the rod severely bent, ok no biggie seen it before just going through the motions, now here is where it gets interesting. the number 4 rod bent so bad that the piston when coming down hit the crank and the ring that the crank position sensor reads. the ring is now bent down ( now it is no longer perfectly round) in a certain spot.
My question to you is can i just heat and bend the ring back into a more round shape so the magnet will still pick up a signal or is this something that should be replaced which would mean pulling the engine to get the crank out, which i am trying to avoid.
how strong/sensitive is the crank position senor magnet? will the slightly bigger gap between the sensor and the ring at that one point effect the reading (electrical signal) to the point that it would effect the engines ability to run properly?
do you guys highly recommend pulling crank and replacing the ring? only 4 stinking allen screws but another couple hours in labor? i just dont want to assemble new engine and find out the CPS isnt reading properly.
thanks guys any input is appreciated
