Does anyone knot what this does? It lives on the back of the engine block on the turbo oil return pipe, next to the dipstick. Its leaking oil out the tiny pin hole on the top next to the brass bit. It also has a wire connected to it. Help appreciated.

it looks like oil pressure swich

 

what he said ^^^^^^ and they often leak

 

Is it best to block the hole up or just get a new one?

 

get a new one they arent expensive between £6 - £12

 

Wheres the best place to get one?

 

any motor factors sell them or you can use the hole to put a oil pressure gauge in

 

ebay?

 

Ordered £7. Was well pissed off, had the switch out and forgot to put it back in and started the engine for a few seconds oil went everywhere . what a nob.
