Re: Hydraulic Lifter Treatment
Is it only on startup or all the time? If its only on start up it could be the variator, I'd be asking what they did that might have made it noisier. Did they refit your head (so to speak!) or a different one? You can use additives to quieten down engines and sometimes its the best solution for an old or high mileage unit, but I'd want to know exactly what it was before taking any action. On a more general note I've been using Wynns stuff for years and its always done what it says on the tin!! Good luck.
Any tea in the pot?
