ok i've just built myself a '65 109 and fitted a 200tdi whilst i was at it, a nine month full strip and build
slight engine mods of a 300tdi turbo with straight through exhaust and TD5 intercooler, turbo to clear chassis rails and intercooler because it's the nicest fit of all, straight through exhaust because i built it myself out of scrap and like the sound
it's only been on the road for about 8-10 weeks and is performing brilliantly, economical, loads of power and a pleasure to drive, it's even comfortable after my old 88" bitsa
now the snag is it seems to have developed a rattle (yes, i know 200tdi's rattle) that only appears once the revs have climbed (it can be heard in all gears) to motorway speeds, 55-60mph or higher (3.54 diffs so the engine isn't screaming), drop below 50 and it goes away
anyone have any suggestions as to the cause ??
