All the sudden.....TICK TICK TICK?? Ideas? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys, hope somebody can give me some ideas of things to check.
I drove home from work today for lunch and let the truck sit for an hour before I got ready to leave. I just put a new performer intake and carb on this weekend and the truck's been running great. Before I started the truck after lunch I checked and re-torqued the intake bolts and thermostat housing bolts. They all needed snugged down a bit. Started it up and I get this fair volume tick from the #1 cylinder area. The weird thing is it isn't constant....it ticks about 8 times and then is quiet for 2-3 seconds and just keeps repeating in that loop. It kept doing that all the way back to work (only time I can hear it is at idle....super 40's ain't quiet!) but it ran like a champ. It doesn't sound like a header leak to me (got one of those on the other side

), all the plug wires are on tight, oil pressure is normal and the tick doesn't get louder when rpms increase. The whole ticking, quiet, ticking, quiet loop is what's really throwing me. What should I be checking?? Thanks guys, sorry for the long post!!

btw....motor is rebuilt 355 with about 8k miles

You might as well retorque your headers so that you can definately eliminate that as a possibility.

When I left work last night the motor was back to normal. Well I pulled the valve cover last night to make sure I didn't have a loose rocker and everything was tight. Also torqued the header bolts. Not sure what the mysterious tick was. My only guess was maybe a lifter bled down and was having trouble pumping back up? Who knows.

Could maybe be a spark plug wire arc?

Probably a lifter. You never quite get all the dirt and antifreeze out of the system when you do an intake swap. That gunk might have made its way up to a lifter and eventually passed on.

That's kinda what I was thinking. Everything seems fine now and she's running like a beast!!!

I would check the header pipes for tightness and then I would listen closely, there is a possibility (somewhat remote that the lifter had a POS in it and it was collapsing some, because it didn't pump up properly. If the noise had been on the other side or it sounded as if it was down lower, then there is a possibility that the fuel pupm was getting weak. They can sound like a "tick" or a rod knock.

I think some foriegn particle got down between the piston & head. It finally spit it out.
