Default C6 oilpan

I've seen a few posts where people are using a C6 oilpan, and I'm wondering if it's a direct bolt-in or if there are any required modifications to make one fit in a C5.

"C6 oil pan"? What's that?

LS2?, LS3?, LS7?

Obviously, not an LS7 since it's dry sump.

I assume that the LS2/3 pans are the same, but I won't swear to it. Hence, the reason for my question.

No "obviously" about it. You didn't specify what it is you are doing or would like to do. Maybe you're considering LS7 and wanted to determine if the oil pan is compatible with the C5 front cradle/cross-member.

Try calling either of our two corvetteforum GM vendors and determine if the LS2/LS3 pans are the same first and go from there. Fichtner Chev or GMpartshouse.

Good luck

I have read the LS2 pan works but there is some loss in oil capacity. I have also read the internal baffling is better. You may turn up information by searching on the LS2 pan both here and in the racing section.

You do lose capacity but a small amount, but the oil control is better for road racing. I have also heard that you can actually get to the starter with the headers on much easier as well.

The LS2/3 are the same pan. You will use your same windage tray, but you will have to get the dipstick and tube from a C6.

Thank you all for your responses!

I wasn't sure if it was a direct bolt-in or if something had to be modified in the process. I'm thinking of making the switch just because the batwing oil pan seems to get in the way of everything when working under the car for some reason.

Most likely the batwing to the C6 LS2/3 pan.

My dad had an LS2 and an LS3, both were Z51's and the pans were the same. BTW the Z51 holds more oil than the non Z51. Z51 holds 6.5 quarts compared to the 6 quarts ours hold.

His stock oil pan to the one he wants to swap to. LS1 batwing to a wet sump C6 pan.

The service manual makes no distinction between Z51 and non Z51 for the C5, both call for 6.0 quarts without filter and 6.5 quarts with the filter. The 2005 also has no distinction and calls for 5.0 quarts without filter and 5.5 with filter. I don't have a manual for 2006 and up so I can't speak to them.

Yeah the C5 is the same no matter what. The C6 is different according to the owners manual, I think the Z51 has an oil cooler similar to the one on the Z06. The '05 Z51 is different from the '07 and '08 but it still only holds 6.0 quarts. So either C6 oil pan will hold the same amount, the oil difference is the cooler so I stand corrected from my previous post.

Completely agree. For those not wanting to do a big involved oil system it makes for a nice upgrade to hold the oil better in the turns. Remember to get the pickup, dipstick, and pan. Everything else is a direct bolt on.
