74 power wagon dream truck...

Frying pan into the fire... First four of the 8 spark plugs I bought had been previously installed so I had to go get new ones and on the way up there I noticed the check engine light came on on my 98 ram and to top it all off after I get it all back together it still was making that exhaust leak kind of noise. I took the oil cap of the passenger side valve cover and could hear it predominantly and put my hand over it and could feel exhaust or air popping out of there... Call the machine shop and likely have blown the intake gasket at the exhaust crossover into the engine...
