another lifter noise thread. little different though Ok i did a search and im tired of hours of reading through threads and not seeing anything realated to my issues.
car is 99z. stock engine. minor bolt ons, converter, exhaust.
I raced the car on sunday and after the burnout it had a bad lifter tick. car still ran fine. ticked all the way home. Let the car sit for about 5 hours and started it up. tick was still there but then slowly went away.
The was fine all the way till last night. I stopped on a road to test out the car. launched and ran through the top of second....as i slowed down i could hear it start ticking again. Then all the way home it felt like it was running a "little" rough....not missing...just not idling perfectly smooth like it normally does. So i drove it home and parked the junk in the garage.
This morning start it up...tick tick tick...then goes away. now its fine.
I would like to hear if anyone else has ever experienced this and what you did to solve it. When it ticks it ticks pretty loud. Its nice that it goes away...but i like to race the car often and its getting embarrassing then when im done with a burnout, my car sounds like its broke. Thanks!

Sounds like a sticking lifter. I would change oils and run it for a while. I recently had issues with my DD where the oil pressure would fluxuate. It was thought to be the bypass was gummed up and would require disassembly. I switched over to German Castrol 0W-30 and after about 2K miles the problem went away and has not come back.
Inexpensive, not intrusive (no disassembly of motor) so it might be worth a shot to see if it helps.

We just had this happen on a friends car. We changed the cam and springs. The car ran fine fora while and then the ticking started. Not all the time but on and off. Went to speed to tune and it fell on its face. Turns out id was the start of a collapsed lifter. In the process of pulling the heads to change lifters. He will be putting on ported heads at the same time. No point in pulling the heads and putting the stock ones back on.
