3. One report about a front crank seal leak.

I'm sure there are some other examples people can find out there. I'd love to know how many 7.3L have been sold since 2020?

I'm convinced the 7.3L is a very very reliable, solid motor. Ford designed it old school, solid, beefy and simple. Port injection, push rod, 6 bolt mains, iron block, over sized skirt, over-sized head bolts, forged crank, chain driven oil pump.

The only thing I don't "like" about the design is the seemingly lack of iron between cylinders...small head gasket sealing surface (due to the coolant slits). BUT, there have been zero reports of head gasket failures. Those coolant channel slits are there to carry away heat between cylinders. Heat is a head gaskets worst enemy...so real world performance is proving the design is working in the 7.3L's naturally aspirated application.

I'm loving my 7.3L...only 6,200 miles so far (daily driver), but absolutely 100% glad I chose the Godzilla for my Super Duty. No weird noises, nothing.

My 2018 5.0L F-150 had an annoying 'throttle off' chain rattle when cold. Very common. Had since day 1.
My 5.0L also had a VCT solenoid failure at 60,000 miles. Fairly common as well. Not hating on the Coyote...very very good motor overall. I've owned two (2nd Gen Coyote in Mustang GT) and the 3rd generation in the F-150. I'd buy another 5.0L no question.... So fun to beat 6.2L Camaros and 6.4L Challengers with a 5.0L Mustang (Go Ford) 😀

I'm hearing nothing about 'common' Godzilla issues. Nothing.

Can't say that about the 6.7L Powerstroke (as good as that motor is).
Things I've read about concerning 6.7L issues:
* Upper oil pan leaks ($)
* Radiator Coolant Leaks
* Turbocharger failures ($)
* DEF tank issues / sensor issues
* HPFP failures ($)
* EGT Sensor Failures
* EGR Cooler Clogging ($)

Dig4it - also reported 8 more were at repair shop

And some of these people reported there's failures occurring in the motorhome application.

Been more than one reported about front main seal leaks on FTE:
Rain Desert
scraprat- who's participating in this thread but didn't report his problem.
Jay Carver

Hartford 8018

Hopefully I get the visit with my old cousin this Christmas who's been a Ford master tech for many years to get an update on what's he's seeing at the Ford shop.
