As far as I can work out there are two important hoses (pipes/sleeves) on the 1.9 JTD 8v
1. turbo to the intercooler (bottom)
2. intercooler to the inlet manifold (top - on a 156 1.9JTD 8V it's PN 60676178)
The top hose split/cracked on my car a few weeks ago on the inside of the last small bend as it goes into the inlet manifold. It was pretty obvious to find as there was a fine "wet" oil mist/spray on parts which hadn't been there before. First i superglued the crack and taped it - tape melted off (wrong tape, it doesn't get that hot), so I used a bike inner tube patch on it instead... All good so far.
Prior to the crack/split my car used to smoke badly on WOT. I replaced the MAF and the EGR to no avail, didn't think to look for leaks. No smoke after the patch, although i think the power is down and am interested in how to test the turbo. Any body know if any diags can do this (revs versus boost pressure = normal?) And how much oil should get through the turbo to the inlet manifold anyway?
I'm in Aust. and the part isn't immediately avail (no JTD 156's here) so will be ordering it in from UK. I am considering adding the lower hose as I think it's probably age related. I only say this as I can see the top hose ballooning on boost (revving in driveway). Given there are two hoses in the critical path it makes sense to replace them both.
I can’t get into ePer to see the lower hose part number but I am sure a dealer could confirm if you give them your VIN.
03 1.9JTD8v Sportwagon +GTA teledials for the win!!
