Or further to Ben's suggestion, a blockage on the inlet side somewhere.
Hose between the guard and air cleaner, air cleaner itself (and everyone has been very restrained over the K&N :angel:) delaminating 90*hose or delaminating top hose.
It sounds like it's just lacking air.
Was leaving that to BenQuote:

About to go back pull manifolds back off to see if warped & also check the gasket. I had 2 manifold gaskets, a thin & thick one. I put the thick one (silver - old school looking) on as the thin one was out of a complete kit that I did not want to break open. The original one was a thin one though. Could not see a difference in the two.
Is the intercooler & pipes suppose to get fairly hot under load?
Yes. When working hard in hot weather the pipe after the turbo compressor (before the intercooler) should be too hot to touch. You should be able to touch the pipe between the cooler and the intake.Quote:

Swapped for a thin black gasket. Re-fitted & torqued as per Haynes Manual. Put silicon hoses back on.
Restart & run under load. Have noticed bubbles & oil from between gasket & manifolds?????????
On the street, there is a massive air leak as car starts to boost.
What do I do now? :(
What does this rig weigh? With plenty of accesories and taller gearing they will be sluggish. I sould xefinately actually check the timing. Is it quiet for a tdi? You really need to start with some other basics too, have you done a compression check? Sometimes tgese engines will run reasonably ok with low overall compression, they'll just be inefficient and cycle lots of oil through the intKe system. We can usually pick them down here in winter, they won't start too well on colx mornings :-)
Maybe if you could post a sound byte of the thing idling, and a few decent quick throttle blips and I could tell you a lot about its state of advance/ retard.

Jup, that was our 300 TDI before the rebuild - hated turning over on cold mornings (we get plenty of night frost here in the country). But it's started right off after new cylinder liners and pistons, new valves and new glo-plugs - be intersting to see what happens in early July when things really get chilly.Quote:

The massive air leak was a missing bolt that supports the oil feed line up to the turbo. In my haste to get it running, it was never re-fitted. This bolt fits into a raised boss on the inlet manifold (drilled completely through). So now we don't have the massive air leak but still lack of power.
Then I re-evaluated every thing, even reconditioned the injectors (which were rooted) still no better so off the another LR mechanic. Yep, timing belt out by a notch. Amazed by that as I'd payed my local LR mechanic to check this back in 2014.
Unfortunately with all the sitting around, the injector pump now leaks and needs a rebuild along with few other seals that are now shot.
Thanks to all that have contributed to this extra long process and looking forward to getting out there. Geoff.
