Default 997.2 cylinder check

So it was time to change the oil so I thought hey I will drop the pan and take a look at the bottom half of the cylinders. I have a camera snake, but wonder if I need to take off other things to get to the cylinders?

Any help would be appreciated.

Okay that is a pain. Next to impossible to check the bore with all that stuff in the way. I would have to remove too many items that probably have gaskets or o-rings that I do not have. Maybe the next oil change I can dig into it deeper.

Use a cheap borescope off amazon and put it through the plug holes.

Yea, looks a bit more involved on the .2 vs the .1.

BTW - is that a permanent rubber gasket around the pan? Thats pretty cool if so. Makes it a much simpler job not having to scrape off and re-apply Loctite 5900.

Yep it just has a rubber gasket so no RTV. Glad as I hate RTV, so messy. Lots more stuff in the bottom of the engine than your picture. I was barely able to see the connecting rod ends and part of the cylinder. It also had internal oil baffles in the bottom of the pan like I have seen added in some 997.1 cars.

Interesting to see the difference between the .1 and .2 undersides.

Question, how does one check for bore scoring? From my understanding, it typically occurs at the base of the cylinder. Viewing from the plug hole will not provide a view of that even if the piston is at the bottom of it's stroke? Or does it?

Did you find any debris of any kind in the oil pan or the pick up screen - metal, plastic, etc.

That permanent seal is great as every 997.1 I've seen has had sealant from the original factory install stick in the oil pickup screen which wouldn't occur anymore.

The pan was spotless with the exception of one piece of metal on the pick up screen. The piece is spring steel from somewhere. The one edge is formed so it is not just a piece that was ripped off something. Any idea where this could have come from? Debating on sending flat 6 some money to tell me what this is. Someone that knows the inside of our engines like him would know the answer in his sleep.

Weird. Yes, I'm sure Jake would know what that is from. Does it look like a piece of valve spring; though I can't think of a non-harmful way for a valve spring to get into the sump. I don't know what the chain tensioner springs look like, but that could be another possibility.

Oh yea and the metal is completely flat. Maybe .020ö thick max.

And it's definitely magnetic right (ferrous), and not aluminum?

What kind of oil consumption are you seeing? Also that piece looks a little different than the one i found in my oil pan. Mine was shiny on both sides and ferrous.

Absolutely magnetic. Tempered or spring steel.
