[QUOTE="jeallen01, post: 1108915, member: 176704"] PS to the above Engines are now "engineered down to weight & price limits", meaning they can be more fragile if not "treated carefully" - e.g. that Astra engine was the then current "B" spec with larger main bearings than the lower spec "A" units - a few years the crankshaft main bearing sizes on almost all of the European GM 1600/1800/2000cc engines were reduced to the same dimensions as the older "A" spec ones, whilst the power ratings were raised considerably and turbo-charging became far more common. Draw your "own conclusions" from that about the need for DMF's on modern engines:rolleyes:. [/QUOTE]
