Hey guys my recently purchased 99 5.7 Vortec Tahoe has developed a tick on cold starts. I’m hoping someone knows a way I can find out if this is a lifter issue or maybe a exhaust manifold leak. (Or ruling one or both out)
The ticking begins at cold start of engine and stops shortly after running. The duration of ticking seems to directly correlate to how long the truck has been sitting. When sitting for a hour or so the ticking only last 20-30 seconds from start and then goes away. When sitting overnight the ticking lasts 2-3ish minutes.
After fresh oil change the ticking was still the same.
Are there any tests that can be run at home to pinpoint or rule out a lifter vs exhaust manifold leak?
Any help greatly appreciate!
