This may be of help on the plug readings.

If its a Wet fouled issue a compression check will help you see if its a Motor issue Top end vs Bottom end.

If you have a Dyno shop nearby? a quick tailpipe AFR check my reveal any possible mixture issues.

Lastly Roush has somewhat of an reputation for oil consumption. Not saying they suck, but they advise higher oil consumption is normal in their motors. Info--> Roush Engine Warranty Exclusions.

I haven't notice excessive oil use. I may have added 1/2 quart once between oil changes. The plugs smell like gas when I pulled them. Definitely not wet. I checked each cylinder with borescope and there was a little carbon build up on the pistons. Very thin coat on less than a square inch. I was unable to start the engine this weekend. it turns over and sounds like its about start but I was concerned about flooding the engine. I plan to do compression check just for peace of mind. I think the 02 sensor needs to be relocated. Its only measuring on cylinder. I think it should be located downstream of the collector. This isn't causing my issues but its seems like a bad setup.


Thanks, Mike
