all, my IT manager has asked me for help to fix his 80 YO dad's mondeo TD 1998.. its a lucas fueled TD with a small intercooler, but quite similar to an XUD it seems..
it's blue smoking and a little lumpy.. doesn't smoke at all when cold, but once warm a gentle plume from exhaust.. it doesn't seem nearly as acrid as I remember engine oil burning.. oil level fine and no evidence of HG failure.. turbo and power seem ok, just an occasional miss and the quite constant blue smoke - when warm only....
Did a comp test on a hot engine tonight..
4 - 420 psi
3 - same
2 - same
1 - 390 (but it took twice as long to get that reading as the other 3)
BOL wants 408-480 but doesn't specify hot or cold test..
what do you think?
will upload a vid in a sec, and more questions about the next step, to follow..

it's a fair job to replace rings etc if it is not the problem.. I cant really believe valve issues.. turbo a possible I guess..
help with diagnosis needed..
