In reply to Liz Watkins. Sounds like there's something else going on with the car. What is the code on that check engine light?

2007 Honda CRV, we have had the VVT solenoid replaced 3 times in 20 months. We have new oil in the engine.

The ck engine light came on within 10 hrs of last service. The engine sputters at 2500rpm only.

What else can we do?

Hello Sam, Mazda3 2.0 SkyActiv BM owner here. In my engine KNOCKR negative values such as -3.0° means it’s asking for timing retard and positive values like 3.0° actually means timing advance. Since forever I consistently get KNOCKR as “high” as -7.00/-8.00° (and you can feel it while driving) but only in certain areas, coincidentally those where VVT kicks in. Do you mean that KNOCKR retard must be spread in the whole RPM range or it’s enough it shows in particular spots to suspect malfunctions? Car has always performed like this also on stock calibration and my tuner has told me these values can be considered “normal” under some circumstances…

My Toyota runx 2004 year model and 1.4 engine has the tip of its oil control valve badly cracked by Machanic upon working on the engine and it displays engine check light,oil and battery light on dashboard and the oil light remains ón even when the key has been removed from the ignition and it further causes irritation from the manifold upon revving and at times the engine would stall during cold start, could the aforementioned challenges the reason for the broken or badly cracked oil control valve?

In reply to Edward Bruce. That interval is just fine for full synthetic unless your vehicle sees severe driving conditions. If in doubt, you can always take an oil sample and send it to a company for analysis like Blackstone Labs.

I have a GMC Canyon and i know clean oil is a must, how often should I change it/ My dealer told me use 5-30 Dexos 1 gen2 and change it between 4 and 5,000 miles. Does that sound good?

I’m not sure. I would guess a chain tensioner, not an oil control valve.

Check out this page, I think there may be a TSB out for the issue you’re experiencing. https://www.toyotanation.com/threads/2009-toyota-matrix-corolla-tsb.304437/

Could a blocked oil control valve be the reason for the sharp rattling noise I hear from my Toyota corolla 2009 engine at cold start? This noise lasts for just 2 secs.

In reply to Kailash.

I won’t know for sure without looking at a factory service manual for that vehicle, but off the top of my head, here’s what I think:

A VVT actuator, oil control valve, and VVT solenoid all sound like the same component to me. This should be the part that manages oil flow in the VVT system, via an electrical signal from the ECU.

The VVT tensioner sounds like a timing chain tensioner.
