I looked in the knowledge base and didn't find the answer. My 1998 5.7 Vortec has what sounds like a lifter tick when its cold at idle. After it warms up the tick goes away. The engine has low miles (under 20,000) and is totally stock. It has hydraulic-roller lifters (of course) and I run Redline oil.

1. Should I worry about the noise?
2. If this is caused by a sticky lifter, is there a way to cl;ean it...like with Miracle Oil or something?

Thanks for the tips,

Dave

Thanks Restore and Dblvision. I'll give it a try next time I change the oil. I just changed it and went to Redline 10-30 and a K&N flter vice Redline 5-20 and a Fram filter. It seems to be better but it still ticks noticeably when it is cold.
