Have you been able to address sticky lifter without surgery?

[Jake Raby]

The flush is a bad idea... The lifters are 24 miniature oil filters, they have one way for oil to get in, but the only way it can escape is round the piston.. Debris won't pass through the lifter, it lodges and stays there. The flush breaks more crud loose that ends up going straight to the lifters, as they are the end of the primary oil system.

If this is persistent, it probably isn't a lifter.. Its probably a failing cylinder. They sound exactly alike, same tone, rhythm and characteristics. Approach with great care, this bites shops and dealers all over the country with misdiagnoses.
