Major Oil Leak

[Awesomeperfmachine]

Hey guys,
I've developed a new problem with my PSD. Here's the situation: It has developed a big oil leak on the drivers side of the engine. It looks to be coming from a large tube(about 2-2 1/2 inches) that runs from just behind the front of the engine to the rear above the oil filter. More specifically the oil is coming from a seam in the tube toward the front of the engine. What the heck is this tube? Any ideas? If so, How tough will it be to fix?

Thanks in advance for your time,
Daniel

might be the cac tube, try to tighten up the clamps. if they are loose it will leak.

Thanks for the reply 099f350. I'm unfamiliar with the cac tube. The tube I'm looking at on the truck has no clamps on it. I'm just going to pull off the whole tube and see what I have from there. I can see two bolts on the front end going into the block and two on the rear of the tube as well. I'm still curious what the heck it actually does. Is it like a huge external oil line?? I guess I'll probably figure that out when I get it off too. LOL

Happy New Year everyone!!

I sounds like you are talking about the engine oil cooler. it's a large tube that runs from the front cover of the engine to the oil filter Adapter Bracket.

If you are going to pull it off you may want to drain the coolant. The block heater is also plugged into it. There are just little gaskets behind it. It should not be that bad of a job to change.

My 95 F250 PSD is at the dealer's as i write this. Diagnosis is leaking oil cooler. He claims they have to lift engine to repair. the quote for this is $1520.00 15-20 hrs. labor.

Phillip:

I didnt think you HAD to lift the motor but I will look.

I don't think you should have to pull the engine, maybe just move the PS pump out of the way.

Sorry it's been so long to reply! A couple of weeks ago I finally got caught up enough to try and sort out the leak. Indeed it was the engine mounted oil cooler. One of the O-rings had split and therefore allowing the oil to pour out on the ground... The four O-rings and two gaskets were about $70 from the local dealer. I was able to get the cooler off without having to lift the engine, although it took several minutes of turning it this way and that to figure out the position it needed to be in to come out. I did have to remove the clutch slave cylinder from the bellhousing to get it out. All in all it wasn't that bad. I put it off so long thinking it would be way worse and more expensive to fix than it was.
Smokin dually - Thanks for the coolant draining tip, without it I'm sure I would have drowned!

Glad you got it fixed
