I replaced a oil pressure sending unit (twice within 2 weeks thinking the first one might have been faulty but its still leaking oil pretty badly. If bad threads or a crack in that port what can I do?
The sensor would've had to have been cross threaded pretty badly to score the threads in the block so be certain that's where the leak is coming from...they can be pretty misleading sometimes.
Having said that, if you are certain that there is seepage coming from between the block and the sensor there's a couple of options.
You can try using a liquid gasket on the threading when you reseat the sensor (be sure to use brake cleans to clean the port and threads and be sure it's dry before application) since there isn't a crazy amount of psi and if it's a narrow enough gap it should do.
If that's not enough find a compatible 'stop leak' additive for your oil and use with a new liquid gasket on the sensor.
If that's not enough and you can see where the crack/split/hole you can try bronzing the port and re tap it...but a cracked block is serious business and may be a sign of more serious trouble. Good luck!
