valve seals = opportunity for a cam
I was tinkering around with the truck yesterday, cutting the plug wires to fit and looming them up with a pretty cool part I came across while I was looking around Jegs. I can tell you that those cool wire looms are a real PITA. anyway I get it together and the thing wouldnt start. after a carb swap (and adding a 1 inch spacer I picked up) from the 600 that puked gas all over my intake to a 750 I have had some work done on. settling the "its getting fuel" aspect we went to "fire" aspect I put new wires on it and still nothing. so I pull the number 5 and its wet and black.
I think maybe I need new valve guide seals. YAY! I wasnt planning on pulling the heads til way later  I may have to grab another set of heads and get them done so I can just swap them out. once i get the heads off ill look at the walls and see how bad they are. I cant see pulling the top off it and not putting a cam in. if things check out I may have to. so any ideas about the plugs or seals? thoughts on a cam?

I assume the engine ran prior to the installation of the plug wires? If so then you probably have it wired wrong. Did you replace the wires 1 at a time? The wet plugs are most likely a result of your problem with gas all over the intake. The plugs are likely fouled from excess fuel and need to be at least cleaned and dried if not replaced. As far as valve seals, you can replace them with the heads on the engine, do not pull the heads for valve seals unless of course there are other issues such as valve sealing, valve guide wear, etc. If I have followed your repair process accurately I think this will help start the engine. Also, the typical symptoms of the need for valve stem seals is, a puff of oil smoke on start up after engine has been off for a while, oil fouled plugs and oil consumption.

I dunno. I went over the order a few times. the wires were clicked on firmly. I suppose ill get back over there and clean he plugs and try again but this plug fouling is getting annoying. I even swapped carbs a while ago because i thought the 750 may have been to blame.

I had fouling plugs, turned out it was the power valve.

it was brought to my attention that I may not be driving it enough to let the plugs reach the right temp so they are fouling. like they need to get hot and burn the stuff off. any opinions about that?

Put it in second gear and drive 90 mph.
Any side street will do.  Afterthought. I see you have an HEI on your motor, what plug gaps are you using ? Last edited by malc; 06-10-2008 at 12:21 AM.

I think .040 but I cant be sure. I'll check them when I pull them and clean them.
