do need you help on this one. Got cold the other day. Car started up and everything is fine. Bu twithin 5 minute, all of a sudden i lost oil presure. Nromally, it pegs at 3 bar. Then it slowly came down to 1 bar. Nurse the car home. then at night, try starting up, 0 bar register on the guage. Also the timing chain is noisy. Just got in the shop the other day. Up till now, guage is fine so what can be wrong? Thanks.
