Bought this 2002 X50 about a year ago, Finally got around to fixing oil leak, Oil tank breather hose split almost in half, Taking care of all the usual stuff while in there, Pinning coolant lines etc.

 

That's the same hose that split in my car. I suppose these oil hoses are reaching end of life now.

 

Ya, for a $75 hose motor out

 

I replaced every hose. Well worth it.

 

I'm doing all perishable rubber, Motor mounts, Plugs, Not coils cause I already have BBI coils, The way this shop pins coolant lines they will never need re-doing

 

Ok, I really need to replace this hose now.

 

I think in the coming years we're going to see a whole new list of "things to keep an eye out for on 996 Turbos" that were never issues previously but are becoming issues as the cars age. Case in point: the oil tank breather hose.

 

Yay! Another engine out for me coming...

 

I just got my new one installed!!! Yea definitely coming up the age where there are going to be some interesting things that fail.

 

Is it really not at all accessible with engine in?
Can you circle or reference the location from your 2nd picture?

 

There is a picture of it in my post on replacing it: https://rennlist.com/forums/996-turb...l#post18266515
Look at the last picture, it is the "?" shaped hose connecting the oil tank to the engine, just next to the engine lifting bracket.
If the hose clamps are oriented exactly right, and if you can lower the engine enough, and if you have a 6-speed gearbox, it *might* be replaceable with the engine in the car.

 

If you pin coolant lines in car you can't really do it correct. With motor out the shop I use pulls all the coolant fittings out of the casting, Drills through coolant pipe and casting, Not getting any shavings in motor, Re-gluing with modern better adhesive. If you do it with motor in you still have all old glue and risk shavings in the cooling system.

 

From the article linked below:

"Won't the Coolant Still Leak from the Fitting if it's Pinned?

No, because the coolant does not leak through the original sealant. The fittings simply do not have enough adhesion to prevent them from ejecting. Pinning fixes this. Coolant won't flow through the original sealant. In our experience it has not leaked out and it won't disintegrate. We have seen plenty of coolant lines that were pinned nearly 100,000 miles ago, after years of track use, that were still not leaking."

It's to the left of the oil tank on the back of the engine against the fire wall. You have to drop the engine about 4" and then it's accessible. Helps if the OEM pinch clamps have been swapped for worm clamps and they are oriented correctly for access. If that's the case, it's actually rather easy to change out.

 

Another one to look out for is the rubber fittings that hold together various vacuum lines. I noticed one that was pretty rotten and swapped it out for a generic piece from the auto parts store. I maybe should have replaced all of the vacuum lines with fresh ones, maybe next time. I did zip tie everything in the system to ensure they don't come apart.
