S40 V40 Cars: Variable Valve Timing Pulley & Solenoid

[magnuz]

The VVT may be in the first stages of wearing to the point where it becomes noisy, but if the noise goes away when up to temperature, then that would suggest that the oil is getting though to the VVT better when it's warmed up & the oil is a bit thinner. I don't know what grade of oil you have in it, but it may be worth changing the oil to a slightly thinner grade ?

If it has done very few miles, for several years it has likely either say in endless amounts of traffic, never been revved and not had engine oil changed so is just a bit gummed up.

If the test of unplugging the solenoid when idling works, it is the pulley that is worn so will need replaced at some point.

However, a few good oil changes, treating it like you should and using a good oil, will do wonders in keeping it running sweet and will keep the oil system clean, it has likely gone years without an oil change, and anything that relays on the oil system to work doesn't respond well to lack of oil changes.

thanks to all for your replys. today got hold of a code reader and got a code p0010 a camshaft position actuator circuit open bank 1, (1 code only)there was no lights on dash , just did thru trial and error. reset this code , rattle gone again.on idle no rattle, my next step is to take of this bloody solenoid and give a clean. any recommendations for cleaning this solenoid, ie petrol injection cleaner will this do? when replacing back again (with new gasket or will the old one do depending on state) do i need gasket sealant, im in 2 minds, also the nuts when tightening do these have to done with a torque ratchet if so what setting? thanks
