Weird ugly mivec Sound

[Kashikhan55]

my mivec used to kick in just find and smooth but over the lat 3 weeks or so everytime i hit 5500rpm mivec kicks in but has a horrible sound and like its lagging it isnt smooth kick and just sounds plain horrible.
oil was changed just recently so don't think it couldnt be anything to do with oil

any other reasons or anyone else had that problem before?

Oils too thick, need 5W30.
Castrol Edge Sport/Titanium 5W30 is the best.

a quick search shows it just might be the mivec tappets needing a good clean apparently. after which i will flush the engine oil and put the oil recommended above by you

thanks
lets see if that solves the problem

Did it only start after you done your oil change?

no, i got service done about a 2 months ago and couple of weeks later the problem started.

at first it was fine after the service (oil n filter change etc) and 2 weeks later mivec started to die basically

Change your oil to 5W30.
It has nothing to do with your tappets.
Mivec engages with an electric solonoid which lets oil through to engage the mivec cam lobes.
Your oil is too thick and it can't get through the intraget oil channel system.
If oil change won't fix it then I would be looking at possable valve issues (caused by the oil being too thick)
So, change your oil buddy

Yep, nothing to do with tappets. Tappets give the distinct and annoying tick tick sound. Easy to identify when idling.

Don't change your oil to 5w lol. I've put 15w before and its fine. If u want to change oil go 10W.

[silverGPX]

Check the battery terminals and also check the alternator one as well.

[Kashikhan55]

okay so i need some definite answer to as to what oil i should go for as everyone seems to have their opinion whats the best oil i can use thats not thick10w? or 5w

[Daniel2019]

Go with a Shell Helix 10w40 or equivalent, it's a semi synthetic. If you want to front up for the extra cash and more frequent oil changes then go with a fully synthetic oil like Castrol Edge.

Just so you know though if you go from a non-synthetic oil to a fully synthetic, sometimes you will get leaks.

Use a decent oil, not magnatech etc.

[Kashikhan55]

^ thanks 10w it is

Yea I'm running Castrol Titanium Edge 5W-40 in mine, no trouble. Changed every 5,000km but the oil is usually $50-$80 for 5L so not cheap :/

[Kashikhan55]

cost wise its fine for me as long as the oil is good i want best oil
