2013 Cadillac CTS luxury
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.
