Gasoline smell on dip stick??runs rough....
So I did 1 minor mud run and I drove home no prob at all.. Then turned it on and off no prob... got a car wash and drove home fine went got gas no prob then as I was leavi.g the gas station it was easy to start but was running realllly rough... Stuttering bad stalling ect.... Got home pulled all plugs (brand new cap rotor wires and plugs 1 week ago and fuel pump sending unit and filter) dried her out ect put back plugs and wires (in correct order) and still super rough... Barely starts if it starts... Turns over no prob at all... Then I checked my dipstick and noticed a gas smell almost and its slightly bubbly.... Why is this how do I fix and any other suggestions on whats wrong..... Ughhhhh

Fuel in the crankcase can be caused by a number of things. Restricted crankcase ventilation system, blown head gasket or worn rings. Start by making sure the crankcase system isn't plugged then run a compression check to test rings/gasket condition.

Which plugs are fuel fouled ...I would be looking at a injector leaking if ur dumping to much fuel ur not getting a complete burn thus running rough and fuel (washing out) leaking past the rings and going into the oil....

Take the hard lines off and blow some compressed air through them same for the port where they connect to the valve cover at. As for a compression check you need a compression tester. A tester will cost around 50 bucks and a Haynes manual will give you the specs and step by step.

I suggested a compression check also cause if you've never had one done it can tell you a little about the mechanical condition of the motor.

injectors are cake, piston rings is another story. doing rings is basically ggoing to require rebuilding the engine.
if its injectors you can get them through pai. precision auto injecctors.
