Steve, sounds exactly like the old classic WBX lifter syndrome. The WBX is
notorious for this. It happened on my engine even after it was rebuilt and new
lifters installed during the rebuild. There are several steps to take to
eliminate this, some of which I have done, some not, but others on the list
recommend.

First, be sure you have the right oil for the engine. I run 20W50 year round
as I am here in the south. Other parts of the country may require changeovers
for winter operation.

Second, be sure you are using a Mahle oil filter. It has an internal relief
valve with a spring sufficiently strong to prevent leakdown and subsequent
loss of oil from the oil galleries in the engine.

These first two have worked for me. No more clackety clack from the lifters.
However I find I must be diligent about oil changes a filter changes.

Third, and this I have not done, is to add Marvels Mystery Oil to the your
engine oil. This is a Marvelous (good pun) lubricant with good cleaning action
for the lifters.

These actions should eliminate your problem. If not, then you may have to
replace the lifter to get rid of the problem.

Good Luck.
