Whats the loud ticking noise? (Update Fixed)
Alright guys I need help ASAP, as im about to go nuts. I recently sold my TSP 231/237 & steped down to the FMS f13. I was doing the swap last night, got the ported LS6 oil pump on & the O-ring seated properly. LS2 timing chain complete & reinstalled everything just like I did when I did my 231/237 swap. I didnt change the dual springs as they only have 3000 on them. The same with the TSP CM 7.4 PR's. Got everything torqued down to specs, toped off the oil & coolant. Started it up. The oil pressure jumped to about 50 psi & held there. So that was a relief. Then here comes the problem. I had a ticking noise coming form the front of the drivers side valve cover. The more rpm the car goes through the louder the ticking. We let it idle for about 10 mins, shut it off, pulled the valve cover checked the PR's on the front cylinder. Checked the bolts on all the lifters. & all seemed fine. Put it all back together & started the car again. the ticking seem like it quite down a little. but its still there. Any clue what this could be? or where to start? I really need to get this thing going ASAP. Its not missing, It idles fine, still on my 231/237 tune, Its not throwning any codes, The cam isnt installed off a tooth. I triple checked the dots on the cam sprocket & crank. Its only doing it on the drivers side, seems to be the front cylinder. I havent driven it yet, I want to get this issue worked out first. Ill list what I swaped to from. Any ideas what it could be? I know the LS1's are noisey but this isnt normal. I never had a ticking noise with my 231/237.
Was: TSP 231/237, patriot dual spring kit, TSP chrome molly 7.4 PR's.
Now: FMS F13, patriot dual spring kit, TSP chrome molly 7.4 PR's, LS6 ported oil pump, LS2 timing chain.
Thanks,
Vann

Did you replace your lifters? Check them if not. I had the same problem until I put in some Com 875-15 lifters with one cam swap. Haven't had it again...yet. Also maybe your rocker arms, they automatically set if I am thinking right. I use YT's but how long would it take the stockers to set? What tq specs did you use as well?

I havent changed the lifters, They were fine a week ago, & the car hasnt moved or ran since then till last night. They never ticked with my 231/237 & thats a more agressive cam than the f13. The roocker arms were torqued to 22lbs. I was hoping its something I missed or just overlooked. I was up pretty late working on this problem.

Whenever I had a tick it was one of the following...
Exhaust leak
Bent Pushrod
Lifters were stuck
and the worse of all...
When I over rev-ed the car and all of my valves tapped the pistons... the only good thing about this, warranty covered it and bought me a cam
Goodluck man... I hope its something small and stupid!

It would probably run like mine did when I put the coil packs on backwards. Sputtering, backfiring and running rough. I'm sure it's not a spark plug wire since you've already checked that. I could have sworn my tick was comming from under the valve cover, it sounded like metal on metel also. I got All worried for nothing. Good luck with your search.

I just had this happen on my car. We had a dead lifter in the car and it was making the same ticking noise that you describe. I would replace the lifters on any H/C type job IMHO
