Hi,
An interesting situation here, I wonder if anyone came across this with any solutions at the end.
I have a timing sprocket related problem, which manifests in two ways:
1. Misfire under load with warm engine
2. Diesel-y sound of the engine
I have no idea what it could be, nor the mechanics who looked at it so far. They all seem to stop at the timing chain replacement, which is not the solution for my problem.
I have some workarounds for both which make the engine run fine, but with some caveats, as below:
1. If I disconnect the solenoids from the camshafts, the misfire disappears, essentially making the engine to have fixed valve timing
2. There is a pin on the side of the sprocket that becomes loose and disappears into the engine bay, this makes the car sound like a tractor because at every turn the inside and the outside part of the sprocket readjust. This can be replaced fairly easily, I just have to keep buying cheap sprocket sets for the pins.
The following repairs have been done so far:
1. Full timing chain kit replacement (chain, tensioner, sprockets, the whole lot)
2. Spark plugs
3. Coils
4. Mass air filter
5. Exhaust camshaft position sensor
6. Wiring loom
7. Solenoids
8. Solenoid magnets
My guess is that is oil related, wonder if anyone had the same issue and what the proper fix might be.
Cheers
