I have had my 87 951 for 3 years and I have had an issue of dropping oil pressure when the car is tracked fairly hard or on a trip where I run at 80 mph + for any period of time. I can pull over for a few minutes and the pressure goes back to normal when I restart. The PO had the same problem. Some on here thought it might be an Oring prob in the pressure valve.
I had to take the cooler off today to fix some other issues and here is what the bottom line fitting looks like. It is a solid rubber plug that feels like it came pressed in there. My 1st thought was a check valve, but this thing is SOLID rubber!
has anyone else seen anything like this? Seems my coller hasn't been working for years.
Thanks

Maybe the oil cooler leaks, so someone blocked it off?

That was suggested by a friend. This piece is so weird. The rubber insert is almost like it was pressed into it. Like it was manufactured this way. We know its been in there at least 10 years, unless someone along the way tried to f--k the PO for some reason. He complained about the oil pressure drop to me when he went to DE's at Road Atlanta before I got the car.

That certainly don't look right .......

so does the oil cooler even have oil flowing through it?

I reckon not. I'm surprised there wasn't sludge piled up in the bottom of the cooler. My oil would thin out during 'spirited driving', but the water temp would be OK. The fans may have been running on high to accomplish that.

Apparently someone misplaced their buttplug last time they were messing with the oil lines.

I call shenanigans. If that plug is solid, then there is no flow, you would have zero oil pressure. None at all. No oil would ever even reach the filter. The cooler is between the pump and oil filter.

Were the two oil lines connected directly together somehow, rather than to the cooler?
