I was adding oil to my gf's accord when I noticed that the block had a square hole in it, I could see directly into the engine..

The hole is directly to the left of the exhaust manifold.

should I be worried? should I look for the plug? do you guys know which plug I'm talking about?

 

does it look like something bolts up in that hole?
not really sure what your saying... does that hole leak oil?
try and get a pic if possible

 

not my picture, but if you look to the left of the exhaust mani, and to the right of the upper radiator hose you can see it.


better picture, again not mine. in between the nice tuby exhaust header and the upper radiator hose their is a blk plug.. it seems as though my gf's accord is missing this.

 

It's your flywheel inspection window, I'd get a stock plug but no biggie if you don't.

 

yup, nothing to worry about..thats for the flywheel timing mark...like he ^ said
i ran my stock motor for years w/o that cover w/o any problems

 

I am missing it too. It fell off a couple of months ago. No big

 

should get a cover and install it so that crap does not get up in there.

 

^ if you want to... Not really needed.. its just a saftey cover so dust and crap doesnt get in there.. or your fingers when its running..

Should be cheap from honda or free from a junkyard...

 

cool. thanks for info guys. i'm going to see if I can find one at my local junker
