Guys I need you enlightment....
I recently bought a Punto gt. I have noticed a ticking noice coming from the engine's valve cover. My mechanic opened the valve cover and we found out that a cam lobe was worn. The damage was obvious with bare eyes. Also the valve adjusting disk was weared out a lot. The damage was found on the third cylinder's exhaust valve.
So, we changed the damaged adjusting disc and we checked the valve clearances and everything was ok. The noice is reduced.
My mechanic also changed the engine's oil and oil filter. We used Agip i-sync 10-40w fully synthetic oil.
Now the question comes from what i have noticed before and after the oil change.
Before the oil change, the car's oil pressure gauge during at cold start up was pointing 3,1 bar. When the oil was hot, the oil pressure dropped at 2.7 to 2,8 barv at idle.
After the oil change, at cold startup the oil pressure is 3 bar but when the oil is hot the pressure drops to 1,1 to 1.2 bar at idle.
What does this tells you?
I do not have any clear indication of what grade of oil the previous owner was using since there is no maintenace record. :bang:
Ecxept the ticking noice coming from the worn camshaft, there is no other noise coming from the engine.
Also I would like to know which is the turbo's pressure at this car. The car bone stock except a Remus Back box exhaust. My readings are 1,2 bar overboost and 0,9 constant boost.
