My 2nd Daughters car started to make a rather noisy "tapping" noise, a Hyundai excel 1999, 2 weeks after purchase. Despite my protestations...I was un-happy with the pushy guy selling it (private sale).
She had just purchased this and she wouldn't listen to us about getting inspections (you know the scene), she had limited income as she's in year 12 (works part time at Coles). To make matters worse her cousin is a car mechanic and he said he would inspect it..but never showed up despite many promises (and offers or $100+)
Anyway this noise sounded, to me the pessimist, like a valve lifter or big end bearing. I didn't know, the working of a car engine are but a waste of physics/energy conversions to me!
We took it to a garage that flushed the engine & put in new oil...the car started smoking on start-up.
To cut to the chase it (the new oil fill) must have flooded the valve lifters seals, which are obviously on their way out but fixed the noise...must have been a valve lifter.
But it all settled down & it runs fine now ..no smoke and more importantly no more tears!
A lucky escape at that! But at least she now listens to our advice..or "am I dreaming"?
