OK, my mum has a skyline and the lifters are extremely noisy. The only time the noise goes down is when the engine gets really hot but they are still pretty noisy. We took the car to a mechanic and he said that the oil pickup in the sump could be damaged because the sump has a MASSIVE dent in it. We got this engine put in it after the original died on us so im guessing they must have damaged it somehow. ( long story with these wankers ) Im now not sure if it could be the oil pickup or the lifters or both because when the car is cold, the noise is constant but as it warms up, the noise is tick tick tick silent tick tick tick silent etc. I took the oil cap off and stuck my finger inside, felt around and noticed little bits of hard stuff could it be metal shavings ? If it was my car, i would gladly rip the rocker cover off and the sump and check it my self but my mum doesnt want me to touch her car lol :hit: So what i wanna know is, if its both the lifters and the oil pickup, how much is it going to cost to fix ? Should i be concerned about the metal shavings ? Besides the noise, the car runs fine and has tons of power but i have noticed that as it does the ticking noise, I can actually hear the exuast putting ( you have to pay close attention to notice) at the exact same time. So could the valves be damaged to ?
