Hi, sorry if this has been covered a few times i read up but can't seem to determine if its an issue or not in my case. When my car is cold (sitting over night or after work), when i start it and drive its ticking from the engine, does not do it when idling, you can rev it slightly and hear it, but mainly when driving off lightly. After about 1 minute its not there. So its either the lifters or piston slap? The motor does not burn oil between changes. I am not fussed about the noise if its not an issue, just want to be sure its not something wrong with the oil pressure or something not going to the lifters. Running 10/40W shell or mobil oil, am going to try nolun next, is it worth putting a bottle of lifter free up in it?
