Oil Leak

Car (2006 Pontiac Pursuit, 2.2l auto with 140 000 kms)has developped a small oil leak that seems to be coming from rear main seal or oil galley plugs (as per TSB 06-06-01-013).
Been running 5w30 full synthetic oil since new and now thinking of going to high mileage oil hoping to get rid of this leak ( a few drops on the garage floor overnight ). Maybe lost 1/4 of a liter in the past two months.
Haven't heard or read anything really good about additives to stop leak
Trying to avoid engine or tranny removal...any suggestions!

Thanks

You can try STD oil, but the leak will probably slow & remain an annoyance. Best solution is to (1) get some oil pads to put down on garage floor or (2) fix the source.

Spray your engine with engine shampoo, clean it good around the area where you think it leaks. Then take it for a short ride and check the source of the leak. Maybe just needs to retorque valve cover or a cover somewhere. The ecotec is not a leaker unless the oil pressure switch diaphragm splits. That is easily changed.

Every minute spent angry is a happy minute lost for ever and ever!!!

Already checked the oil pressure switch and its not leaking!
I understand that finding the exact spot where its leakink from and fixing the leak is the best solution...just fishing here and hoping for an easy fix.........

Thanks guys

Is the oil pressure swith located directly below the oil filter housing or is it slightly to the left ( when looking at the oil filter from the top of the engine bay)

Thank you

I tought the oil switch was between the engine and the firewall...guess I was looking in the wrong spot.
Its hard to see if its leaking under the oil filter canister , even with a mirror...do you have to remove the switch to see if its bad...what size socket to remove it and will oil leak all over when its removed

thanks again

I had a tranny shop do it. I think it was about 500.

No, it will leak right from the middle where the wire connects to the tab.

Normally when the Oil pressure switch leaks on an ecotec the starter gets all gumed up with Oil because it sits right below. You might have a little bit of Oil come out but most of the Oil will be in the pan by then.
