I have these sort of white scratches on my hood. I tried with basic polish, but they're still there. They're not noticeable to the touch, and the hood is completely smooth. Is there a product I could use with my polisher?
Btw its a bit dirty and there is some traces lf my polish product.
Everyone told me the lifter is the problem on the n52 (ticking noise) so i replaced all the lifters and even the rocker arms myself, put some new oil and i tried to rev it at 3000rpm for 4-5 minutes i tried everything its still here.
If anyone can help me .
One of them is broken and can be the cause if my 2A99 problem . If anyone knows !
I wanted to check my lifter cause the « famous » n52 ticking wouldnt go away (cold/warm/additives no matter what) i think i found the problem. But i cant remove the body (the head came out) .. if anybody has solution (btw im also changing camshaft / rockers arms (since the rockers arms came out because of this stuck lifter )
The little damage that can be seen on the photo are due to the rockers arms that disconnect from the lifter (see 2nd photo)
This stuck lifter causes a ticking noise on my n52 , so when i removed the camshaft i was that it wasnt in the best state at all, do i need to change it ? Is it completely dead ?
I was checking my timing chain if everything was good when i was changing the HVA (due to the famous ticking sound). Is it normal ? The car hasn’t started since 2 weeks.
