the car gives no codes but the problem is there yet. exhaust cam could reach the set value that was 0 but the admission remains at 10. After a ride the exhaust cam went full retard making the car to stall. No codes yet.

 

Checked oil pressure at iddle 20psi
3krpm 70 psi

 

Did you ever pull the solenoids like I mentioned before?

 

Yes i pulled them out and cleaned.

 

when i pulled the cam sensors were filled with debris. I changed the engine oil every 1,000 miles for 3 times and when I pull the magnetic oil drain bolt was full of debris too. when I changed the oil for the fourth time there were no signs of debris.my main concern is why sometimes the car works fine and sometimes not,when the car reaches operating temperature is when begins to f@$#.what i have noticed is that when i filled with 10w30(cheap oil to do the 1000 miles x3) the problem was more often. Before the 10w30 the car was running with 10w40 and the problem was less often.

 

I think you have a problem with exhaust gear of MIVEC. Could be inside her there's debris...and oil channels are clogged. Just your problem , there is only 4 reasons :
1. Solenoid of ex MIVEC
2. MIVEC gear (clogged oil channels in there)
3. Oil channels in engine block and Head ( But why, then, the intake has no faults .... )
4. ECU ( but it is very little if )

I would have changed MIVEC ex gear...............

P.S. And you did not try to reposition the intake and exhaust solenoids ?

 

Try to change exhaust mivec map to "0" all the time... and see how its drive.

 

Ex mivec already set to 0 according to my tuner. I will change cam gear today

 

What i dont understand is why the car is not throwing codes but the problem still there
