Slight Ticking Noise....
I have a slight ticking noise coming from somewhere in the engine bay. I'm thinking either an exhaust leak or maybe a collapsed lifter from the cam swap, but the ticking was going on before the swap which makes me think its the exhaust.
If it is a collapsed lifter, what causes this and what are the possible reprocussions? Thanks for the info!

Did you measure for length, and if so what length/type of pushrod were you going with.
Exhaust leaks happen, but tend to be rare on LS1's due to exhaust port spacing. You dont run into the issues SBC and LT1's that have an issue with 3/5 and 2/6 cylinders.
Unfortunately you pull heads to inspect lifters so you really want to make sure its a lifter before doing the job.

I decided to chase a noise my cars had forever... even changed the lifters... no luck. Only thing I did discover was the lifter trays slapping around making some noise. Replaced them as well but it still has an odd tick to it. Been making the noise for over 100K now...I just gave up.
