I am unsure of how bad the heads were warped. I'll check my pictures if I have any piston close ups.

What a beautiful sight...

My engine is back in one piece.

RANDOM STUFF AGAIN...

Remember to change your oil







look at that gunk

Good news!!

this has been a great thread, keep up your reports once you're using the car. This might end up being a good advertisement for 9XX.

That last picture of the sump . . . OMG! Luckily when I pulled mine, which was original, it looked like it was on it's first oil change! Running the oil to long in these cars is a death sentence!

And the manual recommends 15,000 miles, lol.....

Based on the sump pic, I'm wondering if any of the PO's used dyno oil for awhile.

Glad your engine is coming along nicely(and quickly).

I was thinking the same thing, or maybe they were using cooking oil ... that pic is unbelievable.

I removed my oil pan yesterday to install a deep sump kit and baffle. Was relieved to find no sludge and no metallic fragments. Had been having nightmares about finding a quarter pound of timing chain pieces :-)

Was that your sump or another engine at the shop?? Those pics are pretty unbelievable. I can't believe someone could let it get that far and not notice...

Rubik

Enjoy the newly rebuilt engine!

I've seen engines with more sludge that that. It has little to do what oil was used but everything to do with NEVER changing the oil at all.....the owner just kept topping it off for years. I bet you that's the case here too.

KrazyK

Absolutely correct. You cant convince some people, though.

Oh and BTW, that intake should always be covered, not open while the engine sits around.

If you think about it, it kinda does as synthetic oil lets one neglect your OCI intervals longer since it doesn't break down as fast as dyno and can provide better protection even in extended situations over dyno.

The above pic looks like the PO took Porsche's 15k OCI but was too cheap and thought he could do those intervals with dyno oil.

Wow, as a new 04 C2 owner I read the whole thread with great interest; thanks! Ralph

As probably most know, another way to sludge & ruin an engine is not allowing the block & oil temps to get hot enough ---long enough, for the oil to do its cleansing & release of moisture----inherent in synthetic lubricants when cooled. (short trips)
