HELP!! i may have a little problem........

ok my mk2 golf 1.6td has developed a small problem that i cant work
out! on idle, it runs fine and 100% but when its upto temp and your
driving, it sounds as though its running down onto 3 cylinders, yet
there is no power loss whatso ever and still flies along quite happily!
there's no smoke or extra fuel consumption either. surely if it was
running on 3 i'd have 1 if not all 3 of these faults!?!? i cant work it
out! it was discribed tonight like sounding like a diesel
scooby..........

was just wondering if anybody else using this engine or something
similar could maybe shed some light on it coz im startin to get worried
about my lil van.........

Cheers

dunno mate hope its nufin serious!

im sure some one will no something.

Oh bugga...Im puzzled Well if you havnt got any power loss then what about Diesel injector starting to wearout, sounding a bit rattly on high rev. I know this sounds silly but could it just be something vibrating under the bonnet when the engine hits certain rpm. Maybe try sitting still and slowly taking it up to 3-4000 rpm and see if it makes something vibrate.

I only say that because I cant think on bugga all else.

it idle's fine, and revs fine, its only under load........its got me baffled

Lift pump diaphragm may be ruptured (if fitted). not sure on this engine, but this would normally cause at least one cylinder to 'drop' under load.
Failing this, you're then looking at compression problems, which isn't good....
