I've had a moderate oil leak for a while. It seems to be coming from the area of the circled bolt: http://s397.photobucket.com/albums/p...0825marked.jpg

Questions:

1. What is the bolt that's circled?

2. What size is it? It's at least a 23mm, but I don't want to start buying sockets that I'll never use again without knowing the right size.

3. Is it a likely source of a leak? Does it have a gasket that can be replaced?

 

1. That bolt is attached to the power steering pump pressure hose.

2. Get a 15/16 wrench for it.

3. Yes, it is a source of a leak. There are two copper washers that should be replaced.

 

i have a PS leak only during the cold weather but not the warmer weather. it has been for a few years. does anyone knows if this the culprit?

 

We couldnt possibly know that without being there looking at it. It "could" be your problem. Could also be the hose itself, or pump seal, or low pressure hose clamp. probably a hose due to the rubber getting hard in the colder temps.

 

Thanks Trini. You're right about the size. I wish they'd make up their minds between SAE and metric...

 

I know the size because I spent the lapor day weekend dismantling my upper oil pan and timing cover. I had to swap the pump because of a humming noise and I picked up those washers and a return hose from the dealer to go with it.
