Engine ticking sound - driver’s side
The more time I spent with my lovely C5 the more surprises I discover 😊 Back in the garage after a quick drive, I noticed a ticking sound on the driver’s side (thanks to the garage’s acoustic). Engine is warm, and video is below for a sample:
I don’t believe I notice it when cold, which makes me question the idea of an exhaust leak. I would assume the opposite would make sense (as material expands with heat, noise would be louder when cold), although I’m completely new with this engine so I’ve got to learn everything.
Engine is also still to warm for me to go and check the spark plugs yet, but I’ll do a quick check and see if they are properly fixed just in case.
Let’s hear your ideas!
The car has 68,000 miles, a recent oil change (filter shows 2021) but not details on the oil used.

Step 1) Warm the engine up again with the hood open in your garage, if it is a lifter sticking the ticking sound will be very loud; Post up if it is in fact much louder? Post up the results.
Step 2) With the engine warm and ticking, post up the following pressure/temp numbers;
A) Oil pressure at idle>?
B) Oil Temp>?
C) Coolant Temp?
Recommend you do not put a wrench on your motor just yet until you post up results.

After checking out your video, sounds like a lifter is sticking...

Oil is 187, coolant 210. I can’t read oil pressure as the gauge is to stuck at 130, I need to replace the sensor (received it yesterday actually).
The thing is, the car is going a bit haywire with electronics and the fans don’t always engage so the temperature can get really high (when recording yesterday, probably 220 for the oil and 230 coolant). I haven’t been driving the car much since I got it because of that.
I’m going to change my ignition switch today as it seems to be the culprit - see this post: https://www.corvetteforum.com/forums...-show-yes.html

Will do. I actually got home from a quick drive, and no noise this time - see video below.

Perform a full engine oil/filter replacement using the following Mobil 1 Specific branded/type oil...Mobil 1 Extended Performance High Mileage advanced full synthetic
For the oil filter, I recommend the AC Delco.
Full details on this specific oil here at this link Mobil 1™ Extended Performance High Mileage 5W-30
If your engine has excessive sludge deposits due to less-than-adequate maintenance practices, Mobil 1 Extended Performance High Mileage can help by reducing the sludge left behind in your engine. For severe cases of sludge, short oil change intervals (3,000-5,000 miles) are recommended by ExxonMobil for the first 2-3 oil changes as a reduction of the sludge takes place. In cases of engine damage that may have resulted from poor maintenance, even Mobil 1™, synthetic engine oil technology, cannot remedy years of neglect.

LS engines run hotter than most people are used to. Normal operating temps are as follows: from the Factory Service Manual: Factory fan temp settings are low speed on at 226 degrees and off at 219 degrees. High speed on at
235 degrees and revert to low speed at 226 degrees. As stated both fans run at low speed and high
speed and fans are commanded off by the PCM when the vehicle speed exceeds 35mph.
You can force low speed operation at 185 degrees by turning on the AC. High speed operation with
AC on is still 235 degrees.

Received both the ignition switch and the new battery, getting to work this afternoon.

There seems to be a post every week lately by vette owners thinking their cars are overheating. Maybe it's the weather. Just for reference, my car has a 160° thermostat, a 25% underdriven HB and it runs 180° to 200° in the heat of summer.

Also just got the car so really it’s a learning curve. I did get a new 160 thermostat too, following some advice on the forum.
