Ok guys I got my block back from rebuild, Cp pistons 10:1 .020 over, stock rods, standard rod bearing, stock head, arp studs. 1.5mm cometic hg. 2jzge head got new valve seals put in. I got everyting put together and it fired up. When it idles and rev up, no knocking or tapping noise, but when you put it in gear and go, there a tapping, knocking sound coming from the engine bay. I put the car on jack stands, put it in gear, there is no tapping, knocking noise by doing that. I dont think its a rod knock. You can hear it tapping from low rpm all the way to redline. As the rpm rise up it taps faster with the rpm. I drove the car about 2,000 miles now, the knocking, tapping noise stayed the same, hasnt got any louder, no hesitations. I check the valve clearance and they are all within toyota’s spec. Compression is 200-210psi across the board. Its got the older style driftmotion flywheel, old school rps 6 puck clutch kit. Any ideas what this could be.
