I just recently did a heads and cam swap using ported ls1 heads and ms3 and I put the regular comp. replacement lifters and the 7.4 moly push- rods .I put the dual valve springs and tit. retainers.The swap has about 500 miles on it now and just started ticking today out of no-where.I turn on the car and u can here it tick pretty good and then u rev it up and it gets real loud.It sounds like a bad lifter but yall tell me what yall think.Is anybody having problems with these lifters.Let me know thanks!

 

how big is the lift on your cam .. just courious and its sounds like a head gasket to me

 

I had this problem about 5 weeks ago, I had to downshift one day going down the road because this guy on a bike lost his balance and fell right into the middle of the road and I downshifted into 2nd gear and redlined it...not good, so after I end up making it to the dairy queen and when I go to leave i start up my car and it does the same thing...a very loud fast paced ticking noise and if i tried revving at all the noise would get louder and after a couple minutes the noise would go away..until next time i started up the car...well i put up with this for a week because it was only doing it sometimes and then the car started feeling slower and slower so i stopped driving it and i am doing a heads and cam swap right now... I will figure out what was broke around the middle of next week...it could be a number of things but in my case i think it was a broken valve spring or 2. I will post what was fucked up when i know.

 

anybody else have any suggestions!!!!
