to get that code then this points to an issue with the cam timing
and there's a few possibilities:
The camshaft timing is out of position due to the timing chain jumped teeth.
The camshaft phaser is out of position due to problems with phaser.
The oil has flow to the phaser is impeded from having an incorrect oil viscosity or partly clogged passages.
The Oil Control Valve (OCV) has a restriction in the OCV filter.
so if the performance is low and there's a rough idle it could well be this.
I'd suggest 1st removing the oil valve and cleaning out its filter and also consider changing the oil if its not been done for a while
thanks for the extra information
so if its using coolant then yes this can be due to a leaking gasket or cracked cylinder head
if you apply compressed air to the radiator cap and remove the spark plugs you may be able to hear the escaping air
as for a fix then I'd say its well worth trying some of this
as I've known it make an effective repair that lasts many thousands of miles
I'd agree to try the pressure checker next and it looks like the inlet manifold has no water in teh upper plastic part but it runs through the lower aluminium part
see the attached image
Can't say that I have
if you would prefer me to opt out and open this up to others then please say so
Hello and welcome to JustAnswer!
Do you still need help?
The chemical testers do not work. On numerous occasions I've inserted the vial with brand new fluid from a sealed bottle into the tailpipe of a running car to prove that it didn't change colors.
It's possible that you could have a leaking intake gasket or cracked intake but it's much more likely to be a head issue. What I would recommend is filling the cooling system completely and allowing the engine to cool. With the radiator cap off apply shop air to each cylinder with a compression tester adapter and watch for bubbles in the coolant.
Jumped timing means that the chain has allowed the cam and crank sprockets to move independently of each other causing the engine to be out of time.
Cam phasers receive oil pressure. Solenoids are used to control the amount of bleed oil from a phaser to alter the cam sprocket's position in relation to the cam itself, to control cam position related to crank position variably.
The cam timing issue is not related to the coolant loss.
Oil pressure can be measured with a gauge. If oil pressure is ok and the engine is clean then the most likely cause would be the phaser. You could try replacing the solenoid but if that didn't work then disassembly would be necessary to check cam timing and if ok then replace the phaser.
If the site had not verified my credentials it would not have been physically possible for me to respond to your question.
Do you have further questions about repairing your vehicle?
Hello, different expert here. My name is***** would like to try to get this resolved with you, if you like.
Alright thank you for that. Since the oil change has the noise and/or code returned?
Could you see any evidence of coolant boiling over out of the recovery tank when it overheated? Sometimes after the fluid has dried up you can see white stains from the glycol under the bottle, around the tank seam, or below on the inside of the body below the reservoir.
Base idle is computer controlled and not adjustable. The direction we go here will depend on if coolant is entering the crankcase. I think that if you lost a gallon and a half of water in 2 weeks you would definitely notice it in the oil. It's pretty obvious on this engine when that happens. The water pump is driven off the timing chain. Sometimes they do fail. They are supposed to leak out a weep hole in the left front side of the block, right above the ac compressor if you're looking from underneath the vehicle. Sometimes coolant can leak there and the water evaporates off the hot engine leaving just a white residue, so you may not notice a drip.
When the water pump fails, it can also leak coolant inside the crankcase. I've seen this several times. I have never seen a head gasket or intake gasket leak on this engine.
Most often though, overheating is caused by intermittent engine cooling fan operation, especially when the a/c is on. There is a test for this requiring a higher end laptop, but you can start the engine with the a/c on and make sure the fan is running on high speed. The module on the fan itself is what fails. This causes coolant to boil out of the reservoir. That's why I mentioned it earlier. It's more likely that is what happened to the coolant.
If after checking these things, you determine that there is no coolant in the oil, we can address the p0016 code, as contaminated oil will cause this code to come up.
The water pump has an o ring and a gasket on the back of it. It bolts to the block and the impeller shaft is driven on a sprocket by the timing chain. Usually if it fails the bearing in the shaft gets loose allowing coolant to leak out into the oil, or if it leaks at the rear, the coolant will exit out the weep hole. It's hard to see the hole with the ac compressor installed, but you should see a trail coming down the side of the engine, if it is leaking there.
Has the code come back? Has the engine overheated?
Alright. Hey, do you have the VIN? If not we can work around it.
