Re: Wierd noise and everything else.
the engine noise could be variator or hydrolic lifters, simply using the wrong kind of oil can cause the lifters to be noisy, no service history? get the cambelt changed asap.. seriously
i bought my 1st alfa, a 156 ts with no service history (also of ebay), the previous owner assured me that the cambelt had been done, as well as a full bottom end rebuild, a few thousand miles later i had a well and truly dead engine due to cambelt faliure
do not risk leaving the cambelt to chance, it will cost you arund £400 to get the cambelt, variator, tensioners etc changed all at once or over £1000 for a recon engine when the cambelt goes
they need to be done every 36k otherwise you risk a very expensive bill, dont make the mistake i did, if there is no recipit for a cambelt assume it hasent been done
