Dead battery, seized engine, lack of air or gas,
Right side of engine all the way in the back.
The oil pan is located right under the engine compartment.
According to the 2004 Ford Expedition owners manual : The drawing of the engine compartment shows the automatic transmission fluid dipstick just to the right of the battery ( when looking into the engine compartment from the front of the vehicle )
First off you are running a bs engine. So there is your problem right there.
CHange the spark plugs from the bottom of the engine. Hope we've pointed you in the right direction.
Its located on the right hand side to the rear in the engine compartment.................
Sounds like a loose or worn out belt on the engine.
sounds like the timing chain guides and tensioners are worn need to be replaced right away. I have an 02 expedition 4.6 liter and it caused the oil pump to fail which siezed the motor.
The firing order for a 1999 Ford Expedition will depend on the size of the motor it has. To find the right firing order for that vehicle, open the hood and note the information on the cross bar at the front of the engine.
Water in fuel? Have vehicle scanned to determine the problem
A gasket leaking will cause this noise. Did you torque to the right specs and in the right sequence then retorque after 3 heat cycles.
the balancer is coming apart.I had this happen to my 2000 montana. if you dont replace it, it will come off and who knows what damage it will cause.
