intake manifold gasket is leaking. They are famous for it around 80000 miles
Intake manifold gaskets are leaking, intake manifold is warped.
I would suspect the manifold itself is leaking around the cooling passages. It will need to be removed and the gasket replaced.
Because the truck is leaking silly if u smell gas why u driving its leaking
It's probably leaking from a bad intake manifold gasket. You could be leaking from the heater hose that comes out of the firewall very close to the manifold. They sometimes leak there and drip down on the manifold. If it drips on a coil, it can eventually ruin the coil. It happened to me.
you need to find where the leak is coming from, but be very careful, if the gas is leaking onto or near any hot engine components such as the exhaust manifold, it could easily start a fire
Most likely the intake manifold gasket is leaking.
Intake manifold is leaking, or worse, cracked cylinder most likely tho, the intake manifold.
Without seeing or pressure testing the system my most educated guess would be that the intake manifold is leaking.
leaking gasket try tightening the bolts a little might help
manifold or downpipe gaskets may be leaking gases or worse, cracked manifold
Engine hard to start, rough idle, fouled plugs, fuel in oil, poor gas mileage
