| hello everybody!! posting up on here because im concerned about my car, i just got done rebuilding my n/a z32 motor i used, block: new rings, new piston rod bushings and rod bearing>> head: new valves, full set of new lifters (ordered from rockauto) and a set of new valve springs (from z1 motorsports) and brand new gaskets everywhere i have about 1500 miles on the fresh motor, the car drives amazing, it has nice power for an NA, it idles super smooth, i did the first oil change after 500 miles with mobile 10w 40 non synthetic, the issue that im having now is that everytime that i turn the engine on when the car is cold, the motor starts making weird noises like a loud metal ticking, almost like a lifter or valve noise till the car is fullly warmed up then it goes away but then if i let the car cool all the way down it does it again. im lost! i dont know what could the problem be!! all the internals are pretty much new, what do u guys think about this?? has anyone had this problem before?? would u guys point me to the right direction?
