96 Sho

1996 SHO 3.4 L 250,000 miles replaced rear main seal at 85,000 miles. No other major repairs. I have been the only owner of this car. Oil changed regularly at 2000 - 3000 mile intervals. After last oil change, I noticed oil leaking off filter. Upon further inspection, it seems oil is coming from above the filter (not an oil filter gasket leak). I noticed a sensor above the filter looks fairly clean in one area like it may have had oil running on it recently (no build up as in the surrounding areas). However I did not see oil running off this sensor. The odd thing was this oil leaked for about 5 min and then changed to a very slow drip when the engine got warm. I have been adding about 1 quart between changes. Does anyone have any idea where the leak is coming from?? Thanks

Re: 96 Sho

First, pressure wash the underside of the vehicle, then, go to your local auto parts store and add a half ounce or so of UV dye. If you have a trouble light, put in a UV bulb and you should be able to narrow down the source of the leak. I'd drive it 50-60 miles or so. I'm not sure how accessible the SHO engine is to view, but perhaps it's something as simple as a valve cover leak...as the car has 250K.

The leak changing to a slow drip has me believe that it is most likely a gasket problem. As the engine warms, the gaskets tighten up allowing less oil to seep out.

Re: 96 Sho

Could it possibly be the oil pressure switch (sending unit) leaking?

Remove the tube that the oil filter screws on from the block. This holds the oil cooler on. There is a groove in the oil cooler for an o-ring. The o-ring is not listed on the parts breakdown but I installed one in the groove and stopped the leak. Might be your problem.

Re: 96 Sho

Yes it was the oil cooler leaking. I went on another website " Care and feeding of the SHO " and they detailed how to take care of it. Done now and working fine. Thanks
