Hi all I have a 1988 Fourtrak el 2.8 turbo diesel which for most of the time is wholly reliable,I do however find that first thing in the morning she smokes like a factory chimney,but seems to disappear when warm,also she dont like hills at all sumtimes have to go into second gear could this be fuel filter? Or is she just knackered anyone help please can still get 70 mph on the flat tho.Also seems 2 leak oil round turbo.
