Previously everything worked fine. With a silent engine and steam usually coming out of the exhaust when the car is started in the morning.
Few weeks back, I started the car but heard some rattling noise from the engine compartment and then the engine oil light began blinking.
I checked the engine oil gauge, it was okay, I changed my oil about 4 weeks earlier with mobil xp 1000 synthetic.
I called my mechanic who now came and unscrewed the oil filter and then screwed it back, the rattling noise stopped and the engine oil light in the dashboard stopped blinking.
I then tried driving the car but as I was driving a little distance, the noise came back stronger and the engine oil light started blinking again, I managed to drive back home slowly with the noise.
My mechanic then changed my oil and fixed a new oil filter but the noise still persisted. He then told me that the noise could be coming from the timing belt, he requested I buy a new roller chain for the noise to stop.
He opened my engine and removed the timing belt ( roller chain with yellow marking) which came with the vehicle from US, thats the first time the engine has ever been opened.
He took some money from me to buy a new roller chain ( this one had no yellow markings on it).
After fixing it; the rattling noise still persisted.
He then unscrewed the oil filter with the vehicle still on, and screwed it back; he said my oil pump is weak because he expected so much oil with pressure splashing on him in the process but that it wasnt the case as the oil that splashed on him wasnt with so much pressure.
He then took some money from me to buy oil pump, saying it will solve the problem.
After fixing a brand new pump ( according to him), the noise came back stronger with the engine oil light constantly showing on the dashboard.
As it stands now; I'm tired and confused that my once sweet and smooth running car is now heading for the quagmire.
The mechanic seems to have run out of ideas.
I have advised him to put back the original timing belt (roller chain) and the oil pump which the vehicle had as I dont think his prognosis so far is successful.
I have also cleaned the oil control valve and filter but yet the rattling noise from the engine persists.
