My 2006 CTS with a 3.6 has jumped the cam timing chains and locked up the engine with only 84,000 miles on it. I am in need of a complete engine to replace mine. Are there any differences in the 2004-2007 engines and are they different than the later non-DI 3.6 engines built after 2008?

Any 3.6 cts engine from 04-07 should be a direct replacement.

Thank you,

I tore my engine out last night to find that there was a couple quarts of coolant in the oil and #6 rod disintegrated. The internals are all junk!!!

I'm having issues with trying to find a replacement 04-06 engine but have found that the 07 is the same engine as used in the 08-09 Saturn Aura, Vue, Pontiac G6, STS, CTS.

If I am swapping over all external engine components can I get one of the later 08-09 engines and bolt it in? These can be found for less than a grand easily with low miles.
