987 ticking noise (possible bore score?)
Hello!
I've recently purchased a 2007 Boxster S and as a new Porsche owner, I am getting accustomed to the noises that come from the vehicle. However, I want to make sure this ticking sound that I hear from the car when it is at idle isn't a bore score symptom. I do not have smoke coming out of my exhaust from cold starts nor do I have excess soot from my tailpipes. The previous owner changed the oil every 5000 miles with Motul 8100. There are no signs of excessive oil consumption. The sound is heard loudest from the driver's side rear wheel.
The sound produced is rhythmic and seems to go away when the engine is revved (possibly because I cannot hear over the exhaust).
Below I have 2 videos to the noise. The first one is just me capturing the noise and the 2nd is when I rev the engine (around 2000 RPM).

If anyone can please provide some insight into the origin of this sound, it would be greatly appreciated!
Thanks so much for helping!

Major symptom of bore score is oil consumption. If no increase in oil consumption, no worries. If not convinced then do bore scope from plug hole AND from sump. Jake Raby has a YouTube video on the latter.

Hi,
Such sounds are fairly typical with these cars and are usually associated with the hydraulic lifters. Try adding an additive to your oil to see if the noise subsides, as this is a fairly simple and inexpensive approach with no downside. The works fairly well.

I hear 3 sounds very definitively.
-One sounds like as loose spark plug.
-One sounds like a belt roller/ alternator
-One sounds like early onset bore scoring
These engines do not make lifter noises. They will throw misfire codes for sticking lifters, but they do not make noises due to excess lash. The noises that are associated with a lifter issue is followed by an interrupted exhaust note that occurs due to a lack of cylinder pressure when the lifter sticks open, and keeps the valve from closing. I don't hear any of that.
I would perform a bore scope inspection through the sump the next time you do an oil service. I would also check the spark plugs and while you are at it do the BDC bore scope check.
All of what you need tom know about this can be found at www.rennvision.tv
Specifically the "Focus on Bore Scoring Part 4" is a must watch.
You must rule this out before you start throwing other things at the issue, or worrying about it. You can do this work yourself with a few tools and a 40.00 bore scope from Amazon. Assume nothing, and quantify everything. DSo this sooner than later, and you'll save money, stress, and anguish.

Hi Jake, thank you for your detailed reply. I plan on taking a look at the cylinders when I perform my next oil change but I am curious if there are any preventative measures that could be done to slow down the process of bore scoring? Aside from the obvious oil change and letting the engine properly warm up. Also, do you recommend an oil sample analysis for my next oil change? thanks!

No clue if this would be the case with our cars, but we had an F150 that had a bad ticking sound and it turned out to be a cracked manifold/header. Maybe check to make sure its not a crack in the header or exhaust system that is making the noise? At least it would an easy fix...
