Thanks Valeriu Moscalu, Finally someone confirming my suspicions after 100s of videos on cam phasers causing low compression, especially running compression. As leakdown test was good and cranking compression was good, but misfires all on one bank on ford 4.6 3v. Guess next step is new mellings oil pump while im in there and timing components with good quality phasers.

Just got a MK7 GTI and from nowhere the dealership saids the engine is toast because it didn’t have compression. The car was driving just fine and at the 7th day of ownership it just dies on the road and haven’t start again. It crank with very low power and you can hear her backfiring while trying to start. What would be the cause I replace spark plugs and one of my coils is damage it fall apart if you try to take it out. Also I can not hear my fuel pump but there is definitely a fuel smell on the engine while cranking. Any other options I can anything else? I do have 4 new coils I haven’t put on because the car is still at the dealership

The lyfters here are hydraulic, they don't need adjustment! They are use oil pressure and a preload spring to achieve corect valve lash!
