As I said in chat, stop driving it in this condition before you really tear up your engine. I'd guess lifters / seals would be a really good starting point since you've changed out ignition components already. I know there's some qualified mechanics on the forum who will likely chime in as well.

 

Sry for your troubles but i don't have good news for you, i see you posted your mileage in KLMS so i take it your up Canada, I just went threw this on my 2010, Dead cylinder or cylinder's, no power engines toast

 

Definitely recommend not driving it until your able to fix these issues as well. It's only a matter of time before it causes much bigger issues.

can I not rebuild it ??

Also update I pulled the plugs out and cylinder # 1,3,5,7 have normal use coloring on them. cylinder #4 looks like it has not burned anything cause its clean as when i put it in. cylinder # 2,6,8 plugs were black as could be. driving home today i burned about 1 liter of oil. was going to do compression but couldn't find my gauge. gotta get a new one.

 

If your burning that much oil iwould say piston rings are cooked or the head gasket has let go. Do not drive it. It'll only make things worse. No good news to be had with symptoms like that. You could use a flash light and look down the spark plug holes for the buggered cylinders

 

Also sounds like if you had a big backfire and then the crappy running and then burning that much oil you may have piston damage as well as valve/etc damage noted above. That sounds like a teardown to discover what has gone bad inside you engine unfortunately.
Good luck...

Update managed to find compression tester

cylinder # 2,4,6,8,5,7 all at 180 psi
cylinder #3 170 psi
cylinder #1 175 psi

no clacking sounds so I do not think its the lifters
A mechanic friend told me that the valves just need to re seat themselves and that it might be the intake gasket.
first I am going to check the coils with a tester and make sure they are not malfunctioning.

 

Compression looks good.

 

This all happened after you used Royal Purple.....i would raise hell with them. Kiddin, sounds like a combination of a few things. Possible burnt valve and electrical issue maybe?

 

I seriously doubt royal purple oil is the problem.

 

Im possibly thinking the miss is coming from a faulty coil. Planning on checking it today with a ignition spark tester.
It seems like everyone I ask tell me its an intake gasket leak. It is AFM and could it possibly being that system is stuck shutting down cylinders?
When I start the engine now it runs decent for about 30 seconds then the check engine light comes on along with service traction control and stabili track and starts running rough again. when i take it out of park and put it in gear forwards or reverse it starts shaking even worse and really starts puffing. But when it get put into drive and you reach higher speeds 40km/h and up the shaking goes away. im not sure if its still missing or not.

 

I dont think it would be individual coils. It isn't likely that 3-4 of them would go bad all at once. It is probably further back in the ignition sequence.

How far back would I have to check?

 

Personally i think some of your AFM lifter's have collapsed

 

OK checked ignition sparks with a tester and i get a big blue spark at 1/2 gap so no problem with coil 2, 4, 6 ,8
when engine is cold it wont throw a code its when it gets up to operating temp it starts burning oil throws the code and starts shaking. In the shop chat most of the people tell me lifters or flat lobe on the crankshaft but those have noises that my truck does not make. There is a faint ticking sound but its done that since i bought it. it is also the same sound my dads truck makes since it was new.

 

Going to take it into the dealership on Thursday and get them to run a scope on it. I've tried everything I possibly can without tearing it down. Don't want to tear it down and find out its some sensor that's not functioning properly. Thanks for the ideas though.

 

I seriously doubt royal purple oil is the problem.

Do you just think It is a coincidence that it happened 4 days after the oil change?

 

I think it is a coincidence unless the oil change was botched. I am assuming you did it yourself and assuming you will vouch for it being done correctly, but I can think of no reason to blame the problem on your choice of Royal purple unless it was the wrong viscosity or something. Even an oil change with some generic 5w30 oil shouldn't be the demise of a motor after a few thousand miles.

 

I have an 09 that is a flex fuel that is doing the same thing but on 1 35and7 I put new o2 sensors in bu didn’t make any difference I’d be interested to see what your outcome is

 

I agree esox07, out of curiosity what viscosity was used?

 

It's not because of the oil, As i mentioned AFM lifter collaspe, but the only way to really find out is bring it to the dealer and see what they say, keep us posted on the finding's

I used the Sae 5W30 for the oil change. With the usual Wix filter.

Got appointment for tomorrow, lets see what they say.

 

I don't think cylinder 8 is a AFM cylinder is it?

No

 

Dealer called me back turns out its a mechanical misfire and to diagnose the problem they need a few hours to take the valve cover off and check out the problem.
So am I looking at an AFM lifter failure?
Anyone have one of these fixed ? How much will it cost me ?
Side note there replacing my throttle body for free.
