I have 06 volvo d12 engine, the head was rebuild and now there is some strange noise - it's difficult to say if it's metal pease hitting something or compressed air comming out of somewhere. I asked the mechanic to redo the tune up he checked everything under the valve cover but everything looks normal. it sounds like a watch..... click-click-click and goes up and down with RPM. Have u guys seen something like this ? the compression test is normal, i also shut off all the injectors - one by one with computer, the noise is still there, same with egr valves... i don't know what to do ?
