Hydraulic lifter failure! WHAT to do? Try?

[lassek]

Hi all.

I had my car diagnosed today. I something is wrong with the hydraulic lifters. But instead of paying a lot of money to change them all, big job and very expensive. Is there anything I can try to make it work? Any kind of cleaning? Something I can add to the oil to clean everything out? Will a oil change and filter change help ? Also someone suggested to run M oil .. a thicker oil for M cars... that could help ? Is this true?


Anyone with a positive experience? Anyone tried it? Had lifter/tappet noise/failure..
