High boost, too much fuel, and worn rings.

This is a piston from my VW Caddy. Same as a D24T piston except for the squirter notch location. This started as a slight misfire, and became a dead cylinder. What should have been a ring juob on a STD bore engine is now a max bore. Yeah it did some damage to the cylinder wall as well. http://i1000.photobucket.com/albums/af125/verdigo59/002.jpg http://i1000.photobucket.com/albums/af125/verdigo59/001.jpg

That sucks... EGTs must have been up there. At least you can save it at max bore.

AT max bore the Caddy lives. On to the Volvo.
