In a previous entry I mentioned a nasty tapping noise which I thought I fixed by installing a new valve spring retainer. I pulled the intake off my flathead and installed the retainer. I thought that I had the problem licked, but with very little driving the nasty tap tap tap came back. I knew to fix it for good I'd have to get in there deep. So it was off with her heads! 

People choose to replace the door lock plunger knobs, or "Lock Knobs" in their vehicles for a number of reasons. Whether the originals are broken or unsightly, or they just want to stand out in a crowd. Replacing your door lock knobs can be a very rewarding process, but if one isn't careful it could be wrought with peril and danger.
