Default Re: Valve Cover

How old is the gasoline that you are running it on....the gas of today is made to burn, not be stored. Some fresh gas may help though the T engine is pretty forgiving on fuel, however this is troubleshooting. Also, run the engine in the dark, after sundown, you can see all kinds of arcing and even a spark plug porcelain light up like a lightbulb if it is bad...you may have something arcing to ground. This is going to be a process of elimination and you may have more than one problem.
Hang in there and step thru it...

We usually go to Wawa on Friday evenings and fill the tank with their R gas. The gas in it now would be from two Fridays ago because we didn't run it this past weekend. I'm still inclined to pull the head, pull the valves and do a valve job on it just for the pleasure of knowing that it couldn't be the valves, and also that I have two sons that are in the shop with me all of the time and are soaking up everything I teach them because they are 20 and 17. I'm sure the valve job time would not go to waste because my dad taught me how to do them around that age. I could also flush out the block and just do a general inspection. I think the issue might be that this engine was restored in the late 1960's, driven about 3-5k and then sat because the owner restored other cars and drove them because they could keep up with traffic. Wouldn't a compressed valve spring be weak after nearly 50 years of sitting?

Listen. If you simply must pull the head for no reason at least do the following; take a dry/wet compression test. Nothing will indicate the engines condition better than that. Since you seem bent on doing valves which might not need it be done might as well confirn the condition of said valves and the rings too. Sitting won't wear valve springs out. Useage will. Don't forget The car doesn't know how long it's been since it last ran.
