That's if I can get my hands on any more...I am plumb out, having used the very last of em on the Targa, alas....but it went to good use.
That pingin noise is NOT good...if that stupid little plate in there is cracked or broke (prolly cracked) it might well make such a sound...take no chances, take the damn thing apart, and while yer at it, replace those stupid hex-heads with flathead screws like the A3 has.
