Hello, I have a problem with the oil pressure. After replacing all the hydraulic lifters for a tic-tic noise with some of them, the noise stills.
The problem is oil pressure is low when rev the engine over 2500 rpm (driving highway for ex.), so the hydraulic lifter is discharged. Do you know where is the possible causes of a low oil pressure?
I have red that the chain tensioners charge with oil pressure and if they aren't hermetic can loose oil for it and pressure decrease.
