I have what I think is a noise lifter in my cadillac, sometimes the noise is somewhat loud sometimes the noise isn't even there, it is a clicking sound. I recently had an oil change about 100 miles ago and I still have the noise lifter, so I bought some Lucas oil additive which is a synthetic oil and I have been told by many it is real good stuff, and can help get rid of many noises. I added the lucas oil and the noise is still there off and on. Does anyone know what I can do or try, to fix this problem without haveing to replace the lifter or having to rebuild the engine. Thank You.

Make sure your oil is filled to halfway up the hashmark on the dipstick - no more: It's easy to overfill a Northstar which leads to excessive oil consumption.

Then, read the article in the Cadillac Technical Archive, up in the black bar ^^^^, titled "Occasional full throttle operation is good for your engine".

The oil additives won't help you: Your engine has static hydraulic lash adjusters and roller cam followers.
