Been having problems starting for a year or more. Truck has 236,000 miles, and I know the plugs and relay hasn't been replaced since I got it, back when it had 146k on it...for that matter, nothing major has been done on it since that time. I was planning on just replacing all of the glow plugs, and the relay. I've got a couple of questions. What else should I be doing while I'm in there? Maybe replace the injector o-rings? Inspect the injectors for build-up?
Can I use high-temp RTV for a gasket, or is it better to buy a gasket kit for the valve covers?
