loud ticking on startup

**absolutetraction** · 10-18-2006, 05:46 PM

I searched and couldn't find anything exactly like my situation. My 98 Z28 has a loud tick and i mean loud, when i first start it up after it has been sitting for a couple of hours. After about 3 minutes it is fine and sounds normal. The ticking is definetely louder now that it is cold outside. My buddy says it could be the pushrods, thinking i bent one. I have an automatic though, can u bend pushrods in an automatic? Thanks guys

if it goes away i'd say its just valve noise and once they get lubed up *takes longer when its colder due to thicker viscosity of oil* the noise stops

Sounds like the lifters are losing oil, is it stock, how many miles, what oil and is it only when cold?

I have noticed the same thing with mine also. When I first bought the car new I took it in because of a slight ticking and they checked it and told me it was normal for an aluminum engine to transmit some valvetrain noises. The car is now over 8 years old and I believe the noise is louder. Not sure if I am hearing a noise from the accessories or lifter chatter. The car is a 98 SS with 30,000 miles and it sits quite a bit in the garage. The lifters may just be bleeding down but not really sure. The valvetrain is completely stock and it runs awesome.

What is dealeo with that. Stock lifter prone to what ever this is? Is there a fix or just a replace. I myself have valve noise and it is driving me up the wall.. my car sounds like a sewing machine. If i didn't have the loudmouth 2 exhaust i wouldn't even drive the car till i got it fixed. It's embarrassing.

I need to locate what this sound is emitting from and get rid of it. I don't care if it's "just valve noise". I want my engine to purrr not stitch a bedspread. If it gets any worse i will get custom plates that says "Singer"

Have a 2000 Trans Am and it doesnt do anything like that. Never heard of that before either. Hope mine doesnt start making that noise

my vote goes towards piston slap.

Ye I thought that too but. Rob at Overkill and others have said it sounded like vavle train noise.

Note: I di a oil change yesterday to 10w30 Redline engine oil and it has quieted down.
