Pretty sure I got a coolant leak. Here's symptoms:
-Throwing codes p0171 & p0174
-I can hear my intake manifold ticking front passenger side
-rough idle on cold starts and eventually stalls if not warmed up
-coolant spills when turning left harshly
-recently had a coil go bad
I've searched the crap out of this problem and still unsure if it's the gasket, a crack or line.. Any helps appreciated!

 

It might be a bad head gasket on the passenger side from what I'm hearing

 

The problem might not be related the exhaust manifolds are known to leak with these causing a tick that could be that problem rough idle might possibly be plugs or coils which could throw codes and the coolant spilling could be a crack somewhere does the truck overheat or does the coolant bubble when its running without the cap

 

I just had pass side exhaust manifold replaced, so it's probably not that. The truck never overhets

 

What year and motor

 

2000 5.4

 

I hear 99 and 00 5.4s were bad with head gaskets do to the switching to pi heads so that could be it sorry I couldn't help more

 

Thanks man I'll look into them

 

Check both intake manifold gaskets first.

 

Pretty sure that's was it is, have you replaced yours?
