Ls3 tick

Also is there a difference what direction the ouling hole in the lifter faces?

Your rod bearings might have a little extra clearance for that to be happening. Get some rubbing alcohol and fill the combustion chamber, that helps in seeing if the valves are sealing.

The oil galley is drilled under the lifter bores, so I usually face them down into the galley. Don't think it really makes a difference though. It's more about hydraulic pressure than anything.

Is that notmal?

You need fly cut pistons with that cam imho.

Besides the obvious tsp never really states or doesnt state at all what needs fly cutting.
But im gonna go with a smaller cam

That absolves them of any liability. I don’t do a lot of cam swaps but I generally check PTV clearance if lift is higher than stock.

I'm super happy with my Summit Cam. I went with the 8715 "Ghost Cam" and it runs great in my car. Great sound at idle, and lower lift so much less of a chance of this happening. Thanks for keeping us updated on your situation. Bummer that happened...

No problem and yea it sucks. I heard good things about the ghost cam
Im looking to get something tailored to my car.
Gonna go with a cam from cam motion

What pistons hit? Are they on the same journal?

If your valves didn't take the hit then definitely get a piece of glass or a mirror (something FLAT) and check your pushrods by rolling them across the surface. I have a cheap glass square from home depot that I use, comes in a cardboard package that you can store it in when not using it. You have to be critical looking at them to be sure they aren't bent. There's a lot of energy needed to ding the piston, it had to be absorbed by something.

Hate to hear you had a contact, but glad it wasn't anything more critical.

Pistons 1,3,5,7 and2 hit
4,6,8 are fine

Anyone know where i can get stock ls3 beehive retainers? I tried summit and jegs but cant seem to find any

Texas speed? Brian Tooley Racing? Tick Performance?

Im lookin for the correct specs for the springs that come in a cam kit

[Sinnister69]

After researchin summit offers their 8707 cam in 3 kits. One kit uses trick flow beehive springs with 318lb open spring pressure and the other two ise dual spring with 425lb open spring pressure
My pac springs have 415lb open spring pressure. Closed spring pressures are the same
So would you huys agree that i can use my pac springs?

[Sinnister69]

Turns out that my valves did not hit the pistons.
When i was changing the valve springs i would forget to open the air line to keep cylinder pressure on the valve so the 1” or so they fell left a mark. I confirmed this by taking one of my valves and dropping them from a 1” height and it left the same mark. Pistons are pretty soft imho

[Sinnister69]

Further investigating since everything looked immaculate i have a feeling an injector is stuck open thinning out the oil and causing the pressure to drop causing the ticking

Oil filter was almost like water

I have the tsp cam for sale in the forum classifieds

[Sinnister69]

Fired up the car started the first time. Tune def needs to be tweeked. I checked all the injectors for any leaks and they were fine
Engine oil was 45psi at cold idle settled down to around 39-40psi after it warmed up to operating temp. And no ticking besides the normal sewing machine noise. But even that got more quiet after it warmed
