Front (or left) valve cover

2013 tl sh awd 6mt calls for part # 12310-RKG-000 which is very expensive compared to part # 12310-R70-A10 (or A00).
When you read the descriptions for the first part # it states that it will fit both the 3.5 and 3.7.

Then go to the second part # and it says only 3.5 for the application.

If the first one says 6AT, 6MT, 3.5 and 3.7 for the same part #, how is the second one different but it still fits a 3.5?

Shop said there is a hole in it. Probably why there is an oil leak.

Update: part # 12310-R70-A10 (which was the cheaper one) fits on the 3.7.

Just curious, how did you manage to get the confirmation?

Repair shop installed it with no issues. Problem with the old one was that when replacing the spark plug tube seals, one of the old seals lifted out with a chunk of aluminum where it seats. It wasn't in a good position to just put some JB weld on it.
