took some pics of the valve cover. it looks like a few of the lifters have been shooting some nasty stuff up through the push rods. don't mind the grass i washed it off.

my car makes the same exact sound but not even close to being that loud, but mine goes away when the car is warm.. so im wondering the same thing...

mine use to go away when warm but not anymore

Why two pics of the same cover?

i could take one off. my goal was to make two different angles to make sure you could see it well. better to diagnose it.

any body else have a look? the photbucket vid was when its hot and the streetfire vid was after a cold start.

Yup, thats a lifter. Im in the exact same boat as you are right now. Im in the process of replacing them with the LS7 lifters.

Heres my link with my videos
Loud ticking from head area

yeah i ask this question on your thread nobody responded. i did a search like i was suppose to, found a thread and nobody answered.

uLs1a · 02-18-2009, 05:13 PM

I didnt see your post in there. Its a pain in the butt getting everything off the motor, so hopefully thats the hardest part

last two replies. Loud ticking from head area did you ever find a part number for ls1 size 5 layer gaskets?
the only good thing here is i think i have a blown head gasket on that side any way. the block is wet and the reservoir is almost empty. now if i can just get my ls6 heads finished.

i was ready where some one was talking about weak valve springs can cause the lifters to go. would ls6 springs with 10psi be considered weak?

I ordered new head bolts, new head gaskets and LS7 lifters from Texas Speed, they had everything I needed. I think it was like $250 for those parts.

How many miles are on the engine?

4.8T · 02-19-2009, 05:03 PM

mine has around 80,000.

i would go with patriot dual springs for 10 psi.

kinda what i was thinking. where is a good place to get them? straight from patriot?

elias_799 · 02-20-2009, 07:07 PM

call up speed inc.

4.8T · 02-26-2009, 09:36 PM

ok so i ordered new lifters, patriot gold springs, arp studs, and gm 3 layer gaskets. got the even bank lifters out. how can you tell if they are bad? they all look the same. i took some apart. one that i think is bad and one i think is good. the "bad" one had about half the amount of oil as the "good" one inside it. i can't squish any of them by just using my finger while they are completely together.

4.8T · 02-27-2009, 03:55 PM

anybody know how to visually tell if a lifter is bad if it looks good?

Mine looked normal but I heard that it could have been inside the lifter

4.8T · 02-27-2009, 04:57 PM

yeah i took some of them apart. one was full of oil while the other was about empty.
