Intake Manifold Removed....Now What? (2014 EL)

[Kafer79]

2014 EL
5.4 3v
Mileage: 150,000

Coolant weeping into #5 plug cavity from crossover pipe causing engine miss. I removed the intake manifold and crossover pipe and saw plastic gasket deterioration at thermostat side of crossover pipe.

Question: What else should I consider replacing while the manifold is out? Water pump? Detonation sensors? I ordered new Ford coils.

Thanks

If it ain't broke don't fix it. Why did you buy all those oem coils?

Don't fix it if it ain't broken.

Agreed. But there is a concept known as preventive maintenance and mean time between failure. At 150,000 miles I need to consider components nearing the end of its service life who's replacement would be aided with the manifold removed.

OK but I fix things when they break. Service life is often 300k miles.

X2. Simply because I don't like setting on the side of the road waiting on a tow truck.

I had over 50 vehicles and never had one towed.........and never fixed things that ain't broke. Part normally give you a warning before they quit. I don't consider miles on a part preventative maintenance. Also, my other truck had over 2ook miles on it when I sold it with the original coils.

Are you able replace the gasket, or do you need to replace the manifold?

Why would he do that?

If it were me I would be changing the water pump with the motorcraft unit as well as The tensioner and 2 idler Pulleys. Preventive maintenance is peace of mind.
