1987 Plymouth Voyager 3.0L - Tappets

The tappets that you refer to are hydraulic lash adjusters. They are not adjustable. Just replaceable. And to note one thing. If you change one you have to change them all. Or else the one that you changed will wear incorrectly for some reason. Don't ash me why. I Had to do this two times. The first was done the improper way and the second, replaced all. Aslo, make sure that your cam shaft is not worn out of limits as well. A well worn cam shaft will cause the same effect because the lash adjusters only adjust up to .1 inch.

Just some things to look for and hints from experience.

That statement makes no sense to me (but then, I am an idiot). 8^)

Can someone explain it to me?

I felt sure the noise coming from underneath the "rocker box" was tappet noise. However, I have had both boxes off, taken away the lifter system and examined it ..... everything appears to be OK! I was wondering if the noise that I hear could be anything else or whether I might be missing something here.

It is a "tap-tap-tap" noise that increases with engine speed ..... it is quite loud on idle and gets worse on speed up. Any ideas would be gratefully received Thanks in advance Tony

one you have

OK - so we can disregard the earlier statement as a myth.
