She has a smote up '93 Accord wagon that won't pass inspection (high Nox in emissions). Being the shadetree mechanic I am, I took a looksee. I found the following things: Oil in all spark plug shafts and fouled plugs. My guess is her valve cover gasket is shot. Sound right? I went ahead and replaced the plugs anyways. There's also seepage on the engine block around the valve cover. Does burning oil sound like a likely reason for the high Nox?

Can anyone recommend a reasonably-priced mechanic in Dallas? Or is this something I could do in a couple of hours with a good set of tools?

thanks!

sounds like the valve cover (including the 4 little O rings) and plugs to me too. but id go ahead and do a good full tune-up on it (plugs, wires, dist. cap, rotor) this would be like an extra 50 bucks, but your girl and her car will appreciate it. by the way, get a decent set of plug wires, the cheapest ones at the parts store will make it run worse.

 

EGR passages are probably plugged up, too. Time consuming, but not too difficult to clean them yourself. Sorry, you'll have to do a search for the how to info.
