I've fitted a Turbo Oil Drain For Land Rover Discovery 2 Td5 1998-2004 PNH101840 - PIONEER 4X4 (https://www.pioneer4x4.com/product/turbo-oil-drain-for-land-rover-discovery-2-td5-1998-2004-pnh101840/)

I removed the old hose with the turbo in situ.

The turbo end is 2x8mm bolts - the rear one a bit fiddly. The block end required a 24mm crows foot and a wobly joint. Once cracked loose, could be all undone with fingers which was nice.

I'd forgotten the new hose flange requires a bolt on the underside of the turbo be replaced with a button head machine screw for clearance - requiring the turnbo to be removed anyway. So if you are following along ... just remove the turbo before trying to remove the pipe from the block end. You probably won't need a wobly with the turbo out of the way.

Before fitting the new hose, you first install a fitting to the block that takes a 27mm socket. The flange was fitted to the turbo on the bench. The hose was loosly fitted to the block, then install the turbo, and finally connect hose to new flange on turbo. The trickiest part is finding the right angles to tighten the hose nuts whick take a 27mm spanner. Having a stubby 27mm open ended spanner would make this much easier - but I managed to get it done with a regular length spanner.

I had read that this aftermarket hose reduces clearance for removing/installing oil filters. It actually makes no difference at all.

The reason I bought the replacement hose was I had an oil leak at the turbo end of the oil drain hose. I assumed this was due to warping of the flange as it leaked even with a new gasket. I'd read about this being a common problem due to the small flange thickness of the original hose. Turns out someone before me had managed to get it to seal with 2 gaskets installed. When I last removed the turbo, one of those gaskets got replaced, but it leaked. When doing this install I found the second stuck to the turbo - so I suspect I could have got it to seal with all surfaces inspected and cleaned properly first time round. An expensive lesson for this weekend hack. Hopefully the thicker flange of this aftermarget hose will see out the life of the engine, and make future turbo removal that little bit easier.

I had read that this aftermarket hose reduces clearance for removing/installing oil filters. It actually makes no difference at all.

I did a service last weekend, and was surprised to find clearance underneath the oil filter was in fact reduced. So much so I couldn't get my very thin profile oil filter wrench in ... I was quite surprised, as when I eyeballed the new and original hoses side by side, I couldn't see any significant variations in their profile that I thought would affect clearance - other than the slighly thicker hose.

In the end, I undid the 27mm not on the turbo end, which providided the clearance needed.

So correction ... if you fit one of these things, expect to have to do that extra step when changing the oil filter.
