guys i need urgent help..came limping home last night,it just refuse to accelarate pass 50kph and a strong rattling noise was heard, parked and it smells burning/unburn gas when i opened the bonnet..minutes later,some smoke (hot water mist to be precise)starts to rise from the back of the engine near the egr pipe..puzzled as the temp meter looked normal. took my rest and pray hard.this morning when i crank the car up, to my horror there was this metal bearing grinding/rat-tat-tat noise that seems to be coming out from the lower rear of the engine.(engine n tranny area).shut it down immediately n check the engine oil,trnny oil..no issue here n i crank it up again but still that fearful noise persist. no white/odd smoke from the exhaust though but it refuse to rev pass 2000rpm. and mis-fires.. i know that the water-pump is failling (pools of water/bubbling sound) but i think this is Dead Serious..do shed some lights cos most of the spares for my car is not available in my location.
