I already read a majority of the thread on VCM just wanted to make sure I wasn't missing other potential reasons for oil seeping into the cylinder. And also confirm that if the compression is not bad the cylinder rings cannot be bad.

I appreciate the information on the bypass for the VCM as that was the next thing on my list to research.

It is a EX-L with 125k.

As said, your issue is quite common; reported and discussed here once or twice every week it seems. It is caused by the VCM. Muzzle the VCM and you should be fine. Never go to the dealer. They clearly gave you bad advice in this case.

I took it to the dealership being that I had never seen the VSA light come on with a misfire

You have had misfire codes before, but without VSA being turned off, on this vehicle?

Yes, cylinder 6 had a fouled plug, replace the plug and it ran fine. I have not had any further issues with cylinder 6 and the spark plug looks like new still, replace about 18 months ago. I will say that I replaced the cylinder one spark plug probably 2 to 3 months ago and it's already coated in oil tip and threading.

Both times I had misfires vehicle stability was on however this is the first time I had the VSA light lit on the dash indicating an issue.

 

[Ted]

Interesting. Generally, VSA is turned off when the MIL comes on.

These J series V6 engines are solid. Outside of VCM they usually don't have ring issues.

While I am new to the VCM issue I would take the advice of @thscott and get the VCM tuner.

However, I would also question the condition of the valve guide seals.
In the "olden days" this was a common issue with oil fouling plugs but compression being good.
No real test for it but changing the seals thus I would go with VCM tuner first.

VCM Tuner II

VCM Tuner II

I appreciate the additional opinion, that's the route I'm going. Once I install the VCM Tuner and swap out the spark plug and try to burn out all the crap back and let her know if this resolve the issue and troubleshoot farther from there if necessary.

I was hoping I would be able to troubleshoot this first because I have a bunch of other things on the list to do like brakes all around, new tires, new canister pressure valve so I'll cross my fingers.

I was not offering an additional opinion. I was simply correcting post #9 that referred to VCM Tuner vs VCM Tuner II. The latter is the one to get.
