Hi,
First post!! Hope you can help
I have attached a link of a engine noise that occurs only after a hot start when the car has been driven for 1.0 hr or so and then left to sit for ½ hr or so before restart. Really noticeable in summer particularly, but also occurs in winter.This noise is not present on a cold start.
It seems to be coming from the VVT cams where the timing belt is, however it is hard to pin point exactly.
I have changed the VVT solenoid on the exhaust camshaft and also replaced the cam position sensor recently. I have not changed the solenoid on the intake camshaft.
My thinking is this: Car has 203,000kms but runs really well. No oil usage between changes (5000kms) very good condition overall and whilst the car has high kms, i'm looking to keep for many years as I had just had the transmission and angle gear replaced.
1: Possible solenoid failure on the intake camshaft? If so is there any way to check before purchasing a new one? Is it ok to disconnect solenoid and run the car to see if sound disappears? If the sound disappears does that mean that the solenoid is at fault or the CVVT hubs?
2: CVVT pulley and actuators are not getting the required oil pressure on hot start hence the rattle occurs until normal oil pressure is obtained?? Is there any way to check oil pressure on these vehicle? Does VIDA perform this function?
3: Possible starter motor engaging for too long only on hot start? How do I check?
4: Any other advice??
Thanks
