I've been looking for new wheels for quite a while now, and I must admit I didn't really consider the MK4 astra initially. However a 2.0 SRI caught my eye the other day, and I couldn't resist asking the salesmen to pop the bonnet and start her up.
I was surprised to hear that the engine made a rather industrious 'diesel esque' like tapping sound for about 30 seconds and only after some harsh revving on my part, did the noise abate and die down.
The salesman was quick to point out that this was nothing to worry about, and that all vauxhall/ecotec engines were the same when cold. So my question is, could the tapping noise be a forewarning of major repairs (and expenses) to come? Was the salesmen telling porky pies and in fact the engine is probably knackered?
Its an SRI 2000, W plate with 46000 miles on the clock.
Thanks in advance.
