Default Oil leaks and power steering leaks

First all I want to thank John and Randy
for putting this owners forum together, I would be lost without all the Information on this forum, and Ernie for the tail light lenses.....
I have a oil leak some where under my turbo, about a 3 inch puddle when idling in A spot for 15 minutes, makes a real mess under the bus after 500 miles
is there an oil line under the turbo to feed the bearing ? I also have a power steering leak, either where the hose connects to the steering box or the steering box, it is so difficult to see these areas I cannot really see where the leaks are, does anyone have similar leaks or any suggestions.
I appreciate any suggestions........

I'd power wash, then run the engine, and look for the leaks. It may take a while for them to show up, but I find starting with a clean engine, makes all of the difference. If the leak is in a braided line, keep looking at it, and it will get shiney before it drips. Good luck!

I did power wash the whole under side, the leak comes down between the back of the oil pan and the bell crank housing and originates under the turbo.
I just can't see under the turbo......

The PS steering leak is most likely a bad return hose.
The line will need to be replaced,the floor has a plate that comes out under the drivers feet.You have to remove it to get to the line,the seat lifts off the seat post.

Dennis, you may want to try a mirror on an antena to see up under the turbo.

Dennis, Are you positive it's oil under the Turbo? Could it be fuel instead?

Remove the steering column covering at the base, this will allow you to see the top of the steering box. Start the engine and see if fluid is leaking around the input shaft.

Follow the tips from the previous posts,
For another temporary stab at the leak,
there is a steering box hose clamp on the return line, at the rear of the battery box at the highest point left side, if the clamp is positioned to be able to tighten the screw , this may slow the leak,
But all the hoses need replaced including the high pressure line, unless it has already been replaced.

Thanks guys, I can deal with the power steering hoses...........has anyone experienced a leak under the turbo ? ....it is definitely engine oil and drips down the crack between the engine block and transmission housing on the rear drivers side and drips off the corner of the oil pan......oil pan gasket is new and good....valve cover gaskets are new from valve lash adjustment...
I know the turbo has to have lubrication, does ant one know if it is a external line or internally lubed?.......Anyone ever replaced or worked on their turbo on a 3208T 250 hp ?.

Dennis ,

I have not removed the turbo, but from the pictures I have there are two O rings between the turbo base and the block, there are also O ring seals on the hot exhaust side and the cold side under the band clamps.
Visit the Cat shop , and get a parts break down drawing and all the gaskets.
