Odd question here..

Recently purchased a 2008 3.7 WK and loving it. Made an attempt to change the oil, but the plug was on there good. I had to take it to the shop, and after they inspected it for a bit, they told me I had a different/newer engine on there. Still a 3.7L, just a few model years newer. I found that odd as the carfax report mentioned nothing about about a complete engine swap or anything of that sort, also the milage on the report matched what I had on the dashboard. The shop owners mention it was common if a repair shop messed up an engine they would go out and replace it, which may of been the case with mine. The differences being, the oil pan was in the reverse order and the oil filter was a different size from what the 2008 3.7L engine should be. My question to you, how do I figure out what exact engine do I have? I'm told there should be a serial number somewhere on the engine. Any help would be great here.

There's not really room for a different oil pan...what kind of shop did you go to?

Perhaps they're used to seeing the 3.7 in Liberty's or trucks?

The filter issue could be as simple as the change from SAE to metric threads...I know the HEMI changed in or around 08, perhaps the 3.7 did as well.

I haven't checked the engine number yet, but what I can tell you from what I've seen myself. The plug for the oil pan was on the opposite side from other jeeps I've seen in the past, others being another 2008 WK 3.7L. So much so that there was no way a fumoto oil drain valve could fit on it, which was disappointing and frustrating as well.
