I am replacing a blown head gasket on the passenger side and want to know how to set the timing chain in the correct position at TDC before i install the guides and tensioners. I did not pay attention to where it was before taking it apart, thinking it would be easy to set in the correct position with the crank at TDC. Not the case. Books i have read say stuff about bright links on the chain and lining them up with the notch on the cam gear. After 150 miles all the links look the same and none of them look bright. Can anyone help me out with this? HELP
