Code P0017 and P0016 popped up, and only seeing a couple kits out there for the timing, im not a mechanic i dont know where to start on diagnosing and things of that nature, plan on replacing the camshaft position sensors but if that doesnt fix the codes plan on shooting for the timing unless mechanic says otherwise, just trying to prepare for it lol. Would appreciate links to kits or if in your experience youve only replaced the chain, just dont wanna break the engine and have to replace the whole thing

It is almost more important to replace the chain adjusters than the chain. But replace all of them, chain and adjusters at the same time. The adjusters fail 1st.

Those codes typically result from VVT servo solenoid valve failure, which is a very easy replacement. Have you checked those?

I havent checked them no, ill try and google it i have no idea what that is. Thanks!
Would hate to see this engine go, so im just scared it is something timing related.

It is something timing related, but there is a 99.9% chance it's the VVT solenoids, which fail very commonly, are inexpensive, and take all of 5 minutes to replace.

The VVT solenoids are notorious for failing and are very easy to replace.

Is there an intake and an exhaust VVT and if so, should both be changed at the same time?

Oddly, when i checked Amazon for that Dorman part# 917215, it says it does not fit a 2008 Saturn Sky.. ?

 

[rjgramps]

Being that they are not expensive, and easy to replace, it seems wise to replace both solenoids.

Just be VERY careful when removing the electrical connectors. They have become brittle with age. The locking/latching feature can get broken. My 2007 Base, one latch was partially broken by a previous owner. When I tried to disconnect, I broke the rest off. I had to replace the connector.

There are MANY listed on Amazon. The fact that so many manufacturers are making them means that they fail regularly.

There are two different solenoids and while it is not essential to replace both at the same time most people do.

In your case you have codes for both Intake (P0016) and Exhaust (P0017) so you should do both in any case.

Do the VVT parts first, if you do need to do the timing chain, CLOYES brand seems to be reputable. I used that. It had all the parts needed. They have kits with and without some extra gears IIRC. FWIW I could not easy get the balance shaft gears off so I skipped them but replaced all the rest, everything was OK.

How many miles are on your Sky?

How many miles are on your Sky?

87k right now, it is driven daily

 

[Craig's Sky]

87k right now, it is driven daily

That's not a lot of miles for today's timing chains.

 

[mstrjon32]

I have another car with an Ecotec-variant engine and it has 191K (miles) on the original chain. It is driven hard and I change the oil once a year, sometimes less. 🤷‍♂️
