I paid to mucha nd before you go and get it done by the lowest bidder I'd check them out with the BBB. I just got my accord back and the sorry F@ckers who worked on my car are going to pay for it to be fixed right. I posted what happened to my car below this post check it out. Don't let just anybody with a set of wrenches near your car unless you know for a fact they can do it and do it right. Average cost I found was anywhere from about $350 for part and labor to about $650. You may have them replace the crank seal, that is what I needed done (since I didn't qualify for the so called product upgrade) and went ahead and had them replace the timing belt, water pump..... Good Luck
