ticky ticky noise?

[luvmymaro]

so just dropped in a new small block for my camaro....nothing wrong with it but after it warms up it makes a ticking noisy(louder than normal) and I cant figure out what it is

i have replaced rocker ams...push rods.twice....and lifters....and stil making noise

any suggestions on what it is or what i should do?

Since you have replaced and adjusted the most likely suspect - lifters, I'd start looking around the exhaust manifold/header for a leak. I got an old stethoscope from my wife, stuck a copper tube in the end and it works fine for hunting down those elusive ticks and squeaks.

BTW - are all the sparkplugs in tight?

Usually it will be an exhaust leak from what you desribed. A piston slap would go away as the engine warmed up and the clearances reduced. A rocker arm noise would be there all the time in most cases. As the header flanges and head surface heat up, the metals can seperate slightly at the sealing surface causing a leak. Try retorquing. Welcome to the world of headers. If you have exhaust manifolds, check for cracks.

exhaust leak sounds suspect to me also.

but did you break in the new and old lifters per the manufacturers recommendations? unless this is a roller motor.

another thing to check might be electrical. I once had a spark arcing from the coil to another wire that had gotten too close to the terminal, and it made a distinct ticking sound until I found and fixed it. thing

I have almost always found that ticks are usually exhaust. I have ripped apart my drive terrain before thinking it was a lifter. I have even gove as far as replacing all of the hyd lifters.

For me it has always been exhaust.

The best way I have found is to go and buy a stethoscope. It sounds stupid to listen to your car for a heart beat, but it has narrowed down the faintest noises every time. I think it is one of the most used tools that I own...

This is a long shot but I had a fuel pump that ticked, sounded like a rod was ready to go. You could actually feel it when the engine was running and you put your hand on the pump.

I had a loud tick that ended up coming from my lightweight fuel pump pushrod. Now, I have a roller tip fuel pushrod. You would be amazed at how much quiter the engine got.
