Hello all!

2004 S with 104K on the odometer.

Started it up this morning and it instantly made a tapping sound.

Shut it down at once. Re-fired.

Tapping continued for about 20-30 seconds then vanished completely. Did not return for remainder of the drive today.

Here's the part I don't know... THIS tapping sound is very similar to a "dry" lifter on an American push-rod V8.

Are there "lifters" on an overhead cam engine? If so, do I need to be worried? Could the be the start of the dreaded piston slap issue?

No CEL or codes present.

Thanks!

Yes they have hydraulic lifters and they can sometimes bleed down over night or just a course of several hours. If it goes away then it's nothing to worry about. Be sure the oil level is correct and you're using the correct oil.
