I installed my new headers today from Rugged Ridge but I broke my rear PCV valve (its like a plastic 90/elbow in top of valve cover) & a piece of plastic feel down inside. So now I'm takin valve cover off tommorrow 1. Does anyone know factory torque specs for rockers?2. Would it be okay to spray out with Seafoam? Future of my Jeep is alternative fuels so cost of gas doesn't stop me from wheelin. So I've got 2 choices alcohol or bio diesel/soy fuels. A. 4BT would be phenomial but I know very little about diesel engines other than glow plugs. B. 4.6L stroker maybe ATK block runnin on alcohol. Familiar with gas engine so not big change. Price of both fuels about the same. Both fuels can be produced at home. 4BT could easily produce more power & I hear is bullet proof but some engine mods may have to be done out of house. 4.6l Stroker can produce good power engines mods all be done in house & well we all know the 4.0l is reliable that's why 300,000 miles on 1 is not uncommon. Just askin for opinions on my choices you guys have led me to some real good decisions before & this will be my biggest choice yet for the Jeeps future.

 

Yea you could seaform it like you say. Just chang the oil after. Why not look in to changing it over to LP/gasoline combo? LP is pretty cheap.
