Hi, i've got a 20XE in a corsa and all was running fine. It was unused for around 2 months recently ( although the engine transplant process, it was out the car for 3 months and run fine after). During this time, i've taken the fuel rail, cam cover, cam belt cover, dizzy etc all of as i had them chromed/polished.
Put it all back together at its tappetting like nothing i've heard before. Although it sounds like its coming from behined the cam cover and towards the fuel rail/inlet manifold area.
I've run some oil flush through the car hoping to clear all the components inside the engine, drained and re-filled with new oil, but its still doing it?
Can anyone offer any suggestions as i've got like 15 hours of working time left to get it ready for PVS.
