Oil Pan Gasket?

[Maximus Gladius]

Yes - sounds like good advice.

I'd wonder - which cylinders were we looking at, or was it a random assortment left and right bank?
The warm compression check may be tough since it takes a bit to get to the left bank of plugs to remove them - it would be cooled down a bit by then.
Other side, more easily done.

I'm concerned about that engine, especially the coking of the oil/carbon bits, and the amount and patterns of the varnish.
Man, I hate to even think that with the troubles Kevin has had!

LOL - he knows about over-filled engines!
6 quarts does nothing, these will easily handle that with no issues at all, but over that, like he found his once, all bets off.
I have a feeling he's one member rather sensitive to that word "overfill". I can see him out there now verifying the exact amount of oil that comes out of each container and contacting the Canadian bureau of standards for verification.

Sometimes it’s good to

Hadn’t thought of this but i did lay awake all night thinking how I could mess up the RTV seeing as how the last time I did that was in high school in the 80’s and I didn’t read directions then and couldn’t find them now

@Maximus Gladius
Straight from the service manual:

Clean off all the old sealant and wipe down the areas with isopropyl alcohol prior to applying the sealant. The manual calls for a 3 to 4mm wide strip of sealant applied to one surface only for the oil pan (don't put the sealant on both the part and the part it attaches to).

This worked out really well! Was really worried I’d mess this up and was pacing the floor at 2:30am. Was done the final torque at 10:30am and have been driving around all day. No leaks! (It takes a community) Thanks for posting that.

I think his posting of the instructions really nailed it. And those instructions are similar to what's been used with many other sealants and so on - it doesn't take a whole tube like some people tend to use. Just stupid to glob it on to the point is squishes out everywhere. More likely to leak, not less.

But - I had a feeling you weren't the sort to put a 1" bead all around it to make sure it had plenty - no worries there.
Besides - you've done this sort of thing before - transmission pan, among other things.
What's the worst that could happen? A leak
You drain the oil out, drop the pan, clean it all up and go from there. You won't break anything, you'd only lose time.

Well, here’s why I pulled my engine oil pan. I could say because the engine turned 3 years and 100k km (60k miles) October 1st so, why not see what was sitting in there but the real reason is the carbon capture in my many filters caused me concern so I did my oil change last week, put a bore scope in there and saw the pick up screen had a lot of blockage from the carbon.

Oil changes were done at 50% oil life meter (approximately 5000 kms). Oil pressure is 30lbs from idle to 2900 RPM then immediately shoots to 81-83lbs @3000+ RPM. No ticks, runs smooth.
This is what I found

I would suggest a couple of OCI's of Valvoline Restore and Protect to help clean that up.

I am betting 90% of that was from the overfill and messing up your intake and PCV system. Switching between oil brands would not cause that.

Varnish of that quantity would be amazing if it would form that fast from an over-filled condition.

The oil coking up, the "charcoal", the lumps - yeah, a lot of oil getting to really hot places where it shouldn't be at or would be small quantities, but the varnish from over-filling?
I don't recall how long it was too full - how much he drove it, how far, how many kilometers.

It's possible the massive amount of air churned into the oil caused some issues with oxidation. But it would take time for it to have an impact.

I agree with the Valvoline R&P to clean it up, but mixing oils can totally screw up the detergents and lead to varnish building up.
It's a "risk" - some mix ok, some do not. Analysis has shown that to be the case.

We all know that high quality full synthetic is the go to oils for these engines.
He drive 1000kms. With 12liters or 12.7quarts in it. That is way way about the windage tray and was definitely bathing the crank and throwing it everywhere in there. His temps got to 248F that sounds like that is what caused the varnish look. But honestly I think It will clean itself out with time He only has 60thousand on that engine.

No 1” bead this time,…back in high school, oh ya, that was fun and i remember getting it every where, like ketchup on everything.

Resisting the urge to repeat all that again was hard and, …I just had to keep saying “less is more, less is more” until I laid it around. I cut the tube to 2.5mm and didn’t look back and it’s worked…so far.
