I am considering buying my sister's boyfriend's 2001 Civic LX but he told me it has some oil leaking. I youtube'd this problem and stumbled upon this video :
I realized when I looked under the hood of my friends car, that the entire EGR Valve piece was missing. It is as if someone had pulled it out and never put it back in.

Is this something serious/expensive to replace? Is there anything else that may have been affected? New to these forums by the way, any help would be appreciated!

EDIT: I also remember hearing my friend say that he is missing the cap for the coolant reservoir. This may explain the oil leak and nasty smell? After doing some research, I found that the radiator could be damaged as well as a result of the missing coolant reservoir cap.

I doubt it is "missing". It would make some serious noise if it wasn't there along with a check engine light. The D17a1 doesn't have it. That is an a2 in the video. What model is it, ie lx, dx, etc?

Call the cops!








So where's the oil leak?

Ah ok. It is an LX and the oil leak appears to be coming from the cap mentioned in the video.

Check this thread https://www.civicforums.com/forums/1...ml#post4651958, there's a catalog link in it.

Or search, this has been covered in the forum several times in the past.

HTH


EDIT: That video covers the replacement rather well.

Was the EGR missing or was it just the plastic cap they replace in the video?

The EGR is not "missing". The D17A1 in the 01 LX did not come with an EGR, only the D17A2 has it.

The cap mentioned is the one that plugs the cam hole where a distributor used to go. Since the D17 went to a distributorless system, the simple fix by Honda was to plug the cam hole with a plastic cap that has an o-ring on it. It is a very common source for a very slight oil leak, and is very simple to replace as pointed out in that video.
