Hi folks, my 92 3.1 intercooled has done 50,000km since engine rebuild has been running great. a fews weeks ago while cruising down m'way at 100kph there was a noise like a fan belt breaking. I pulled up and had a look under bonnet - no probs, all looks ok, no heat, water, smoke and all belts ok. All dash lights ok and oil pressure good so limped to work with engine making louder than usual noise. Later I had a good look and could not find any problems with oil/water etc so drove it to diesel mechanics who claimed there was no oil in motor so put some in and test drove and couldnt find any problems. It was still not running well (sluggish) and noisy. I took it to a mechanic friend who took tappet cover off and apart from a couple of tappets out of spec could not find any probs with valves or springs etc. Im not sure what to do now, I dont want to throw huge money at the old girl but would like to either fix her or sell her to a good home as all other bits are in good order. Would appreciate any ideas on any checks I could do to troubleshoot this. Cheers
