So as the title states guys, now I will try to upload a video but figured I would ask if someone has had this problem.
I have a recent rebuilt oem head. I paid a local mechanic (I knew I should have done this myself, but job didnt let me.) to put the head back together after the rebuild. After running the car on idle for awhile I noticed the cam gears were not aligned, so I redid the timing belt and the belt was good. Later that night took it out for a drive and the car acted weird, then I arrived at my friends house and the car has a noise coming from the head, but only at low rpm, or when you shut it off. I checked the timing belt and it has some slack, but when I press the belt, the intake cam moves a little in, which is weird, because the exhaust cam does not move at all.
Also ever since this happend, my car's turbo is also acting weird, now this is a rebuilt 16g, and no smoke is out the exhaust, not shaft play aswell. I run maft so I should here the turbo spool or whistle you know, but it sounds as if the car had the mani connected straight to the exhaust.
Any suggestions on this guys? I will try and get a video of what I am talking about when I wake up. Any input on this would really help. I am bending towards maybe a bent valve? Or maybe the HLAs arent doing enough pressure to the cam, hence the movement. I also saw a thrrad stating it might be the timing belt tensioner pulley that is not torqued at factory spec. Thanks for any help though.
