Mivec not coming on when car has warmed up

[Pbkyle]

hey guys..the mivec isnt enagaging. It works for a few mins after the car has warmed up but stops after a while. The solenoid is working fine too. The problem only started a short while after the oil was changed. Currently using a 20/50 .. any recommendations?

That's pretty thick tho

[Pbkyle]

ok thanks bro, you have any suggestions? would synthetic make a difference?

[dredman1]

Which engine is it?

Too heavy an oil will not allow the mivec solenoid to operate properly so it wont open.

[Pbkyle]

Its the 4g92 1.6 dohc ..so the thinner oil should work better?

[Aaron 2NR]

Try a 5w40 or 10w40....

[Pbkyle]

ok will try it..ps. the 20/50 oil worked for a few days

[Pbkyle]

hey guys.. just letting you all know I got through.. there was actually a dent in the sump pan , right under the oil pickup, decreasing the oil pressure to the cams..... mivec is working fine now thanks for the help

[dredman1]

Good to hear. Hopefully that slight oil starvation didn't cause any damage.

Good to know. Should still consider using a 10w40 with the Mivec. I use this body in Amsoil in mines and works great.
