I have a 1988 740 turbo wagon with a ton of miles on it (220k). It runs great and I still like it.

It just started dumping oil and I put it up on my ramps and saw exactly where it is leaking from. Just above the oil pan base (on the passenger's side) there is a pipe that comes down into the oil reservoir. The rubber seal around this pipe has corroded and it jiggles around and leaks badly. I don't know if this is a outlet or inlet pipe, or what the seal around the pipe entry into the reservoir is called.

Can anyone tell me what this seal is called and where I can buy one?? I'm assuming I will need to take the oil pan off to get to this pipe to slide it on from inside the reservoir. I already have a new oil pan gasket.

Any assistance would be greatly appreciated!!!!!!
thanks,

The pipe should go into the block and the other side should go into the bottom of the turbo.You can get the gasket from Volvo im not sure if you can get aftermarket.To remove the pipe loosen the 2 screws on the bottom of the turbo that go through the pipe.You might have ti disconnect the waste gate valve to get the pipe to come out.Then fish the pipe out replace the o-ring on the bottom of the pipe put a little grease on the seal only after it is on the pipe and reinstall.Dont forget to put a new gasket on the top of the pipe.The pipe is a return line to let the oil return to the block.
