I recently traded for a civic been wanting one forever for gas mileage. The only one I ever came across I got, and it has been weight reduction- missing all kinds of stuff. (Fan/Power steering pump etc). Now! I know I have a leak on a bearing under the valve cover. Excuse my lack of lingo here. How hard is that to fix? I know I have to remove the timing belt and whatnot, I have the manuals for the car. I say manuals because its actually different parts. B18B heads B20 series block from a 97 CRV and its a 95 civic ex body.
