Whip the rocker cover off and have a decent look. Something may have caused that rather than just a worn cam lobe. Thats down to Lack of Oil....Perhaps with this Oil issue you have been having?

Need to take it off, even with fear that it will leak after that.

Took the oil sandwitch plate off today, put the oil gauge to original dummy light port and meter behaves same, after cams come on, it drops pressure to 0. I have to get mechanical gauge to verify that thing.

Also, could the oil regulator at front cover/oil pump cause problems? as i have really hight cold oil pressure, close to 7bar. maybe it is stuck half open/close and causes this all...but then again oil pressure behaves like it should untill solenoids switch on.

It looks more and more like rebuild :moresarcasm:

Also, ordered quaife ATB qdf17l ....

Something just does not seem right, if removing the sandwich plate, and the oil pressure guage still dropping like that. Looking at those cam lobes, suggest now that the engine is being starved with oil at certain RPM. It might be down to a bad oil pump.

Under valve cover look pretty good, chain is really tight, doesnt move when pressed down between cam gears.

Only intake high cam lobe in c1,c3 shows mark of wear, Others are more and less "normal"

Oil is flowing to the cams oil tube pretty good.

I think its time to get new oil pressure meter, and look what it shows.
