Default Bell housing inspection hole cover?

I have an 09 WRX 5mt that just had some major surgery done. When I went to clean the engine bay (long story) I noticed I could actually see my flywheel exposed behind the intake.

I am assuming there is a cover that is supposed to be there, but was not reinstalled by the shop that did the work.

I would like to get a new one as Iím a clumsy **** and I am absolutely certain if I leave it exposed I am going to drop something in the bell housing at some point.

I looked around a few places and couldnít find a PN that seemed to match the slot, any help tracking it down would be great. Also while Iím at it, are there any other covers on the bell-housing I should check? Thanks!

I'm not sure why it's called timing cover, but tow-may-tow toe-mah-toe, I guess??

If the cover you're looking for resides on the top side bell housing part of the engine on the passenger side of the block, that's the part you're after.

There are a few companies that make a metal bolt on version as factory ones tend to come loose and either fall off or fall in. The shop may not be to blame.

Interesting, didn't know there was a market for aftermarket replacement timing covers.

These are called "timing covers" because back in the 70's and 80's you would time your Subaru's engine based on the timing marks machined into the backside of the flywheel. Pull off the "timing cover," start the engine and twist the distributor to time the engine while you point your timing light into that hole.


Fast forward to about 1:15 to see the timing hole being used.
