Hey guys, in the middle of a head swap on my 4g15 which is my first time pulling a motor to bits, only ever done a clutch swap and basic servicing/upgrades. im having immense trouble getting the crank nut (i think thats what id call it) off so i can get access to the crank gear. ive tried the starter method with a breaker bar but i dont think my starter is strong enough, it just clinked and did nothing. i have an air compressor and might have an old impact but not too sure on that. not sure how id stop the motor from rotating anyway. any advice?
