Hay guys I just did a lt4 hotcam swap on my 1996 z28 and now I hear a ticking sound at Idal.Befor the swap I would hear ticking when I was going down the freeway and gave it gas; over my loudmouth so it had to be loud.But I couldent hear it at idal.Now after the new timing chain lt4 hot cam and springs I can hear a ticking sound at idal.I adjusted the rockers three times; thinking it was them but the ticking never got better.Now I think the new springs and cam are causing the old weak lifters to bleed down causing the ticking sound.What do you guys think.

 

What lifters should I buy?

 

will the ls1's from gmpartsdirect work part #12499225?

 

come on guys help me out hear.

 

You could just get a stock replacement set, they will be more then adequate for a Hotcam set. Also, the Comp 850-16s are another stock spec replacement set option.

 

You could just help yourself out and do a search instead of TTT your post several times within a few hours.

 

are the 850-16s from comp the ones every one is saying not to get because they fail?

 

No, that is the Comp Rs. There is a big sticky addressing it at the top of this forum page.

 

Once again search, search, search. You can buy better GM racing lifters for less money than the OEM replacements.

 

ya I know about the gm lifters I just cant find the part number for them.

 

Do you guys have the part number for the GM racing lifters.

 

are they the 12499225's?

 

Do a search on caddillac lifters and see what ya get.

 

Good call

 

I am going to get the 88958689's from gm.thanks
