Ls3 tick

I also didnt hear it when i pulled the valve covers

Considering you can easily push the lifter down with a finger, your engine is missing, and you can clearly hear its internal mechanical noise, it's a lifter man, not exhaust.

Trust me, was just in your shoes. Had 14 lifters that would support my weight and 2 that compressed with a screwdriver. I couldn't move the pushrod cup with my finger at all.

Stop by any parts store you want, ask to examine a lifter for your car and feel how tight the spring is in the push rod cup..

I agree with you 100%

Does the ls3 have all equal length head bolts? Im looking at arp head bolts and there are a few different sets

[Hotwire]

Anything after 2004 has equal length.

Thank you i found them

Im guessing the lifters faiked because they couldnt handle the 400+lb open pressure springs?

What are the cam specs? Guys are putting grossly oversized cams into literally stock 4.8/5.3/6.0 trucks with just springs and pushrods and spinning them to the moon with zero issues.

I think you just had a bunk lifter to start with.

Dont know the rest off hand but i put pac dual springs that have 400lb open pressure

What I found looking. I'm right on the edge with my single PAC1218 springs.

That cam is going to beat the hell out of your valveguides, that's a LOT of lift. I would say contact TSP and see what they would do to make your valvetrain last, but unless you own a racetrack or youtube channel you won't get a reply from them.

I may just downgrade to a gm hotcam lol

That's normal. You should soak them in motor oil over night before you install them.

Little bit of handy garage knowledge, 16 lifters will fit in a quart bottle of oil.

Finally pulled one head cam looked good as i spun it around. But my valves ever so lightly hit the pistons. Good thing is the valves arent bent and seat fine

[dhutton]

Always a good idea to check PTV clearance when swapping cams. That’s why I asked way back in the beginning of this thread. There is a ton of information out there on how to do it. The springs etc are cheap.

Just pulled passenger head and only piston #2 has the same mark on the intake
