SC oil pressure sending unit leak

SCWDP911 · SCWDP911's Garage

When I recently started my heater backdate on my 83, I must have bumped the oil pressure sending unit in the process, loosening it up a little. It started my first official oil leak. I have tried tightening it up a tad and it helped, but I do not want to overtorque it. I noticed it at work today and I loaned my Bentley out. Is there a torque value for this fitting? Is this thing using an o-ring seal? I am wondering if the o-ring tore or was damaged when it was bumped loose?

Thanks

You have a Porsche AND a Bentley? And you let other people drive it? Wow.

pipe thread - tapered

can you get a torque wrench in there?

Don't know really, have not tried yet... but I do have a metric set of crows feet and thought I could reach it with those and an extension...

that will change the torque value - I would just tighten until it stops leaking -- slowly

OK, will try that route. Thanks

Shane,

I think they use those soft crush washers here. Where does it leak? the sensor is attached to a housing and the housing also has a bolt. Does it leak at the housing or right where the sensor attaches?

In either case if it has those soft crush washers I'd get new washers.

OK< thanks Sal. It looks like I should be able to unbolt this without any big todo. I do not need to drain oil down at all do I? This should give me a better idea of what I have going on anyway...

Thanks

Just un-bolt it should not leak much.

if it is mounted into a block like on a Carrera be VERY careful - search threads on that & do what Jim Sims has posted.
