Just recently my engine has become noisier than usual(not just the normal injector noise) and is a bit low on power
And starting between 3500-4000 rpm in 3rd 4th and 5th it gets even noisier and I get a very bad misfire like I have lost a cylinder (not like a electronic misfire)
I have use engine flush, new filter and oil plus slick50 and its still there, I have looked up on the net and it recommends to check the oil pressure then clean/change the hydraulic lifters if the oil pressure is ok
i can move the followers left and right a little bit too when the engine is warm or cold.
each cylinder has 12-14bar, on the pressure test i did yesterday
Has anyone ever had the same problem and what did you do to fix it?
