Front cover cavitation

Start off by stating I did 2 restore plus flushes over 2 weeks, knocked off some serious scale and rust. Prior to my BPD OC relocation.

Mechanic wasn't familiar with the restore plus. He expressed concerns about possible cavitation of the front cover, because of the amount crap restore + left behind. He wants to explore to see if the front cover has cavitation at $150 hr it's a steep price.

What would you guys recommend or suggest?? Is this a problem that I should explore?

I explained the restore plus can leave a alarming amount of crap behind.

Figure water pump and examination is something that falls under my Patience level:). If needed.


Thanks

Had high EOT hence oil cooler all temps are inline now 7 degree delta 195ect 202eot. Never ECT high temps

flushed quite a bit after restore +, but as I have read through forum it's tough to get all the crap out of system after using that product(shop flushed again before BPD OC install)

Cavitation on the front cover would put coolant into the oil. Do you have that, otherwise, this seems like a fishing expedition?

The chemical is easy to flush out, the debris left behind is not.

Front cover cavitation is not a 6.0L thing but it is with the 6.4L. As mentioned front cover cavitation would put coolant in the oil therefore if your coolant level is not unexplainably dropping I would not waste your money on it at this time. A better reason to pull the water pump is to inspect the pump itself. On rare occasions the impeller may crack and spin freely on the shaft... if your engine temperatures are no longer a concern I would let it rest.

What are signs to watch for of cavitation of front cover, now that they have me paranoid:)?? Is it cataphoric if this happens? I'll be watching for signs like a hawk!!

Previous owner ran straight water from looks of the rust/scale that is/was in system, hence flushing with restore + 2x. New radiator and hoses, new OC and degas bottle.

Easy way, is pull the water pump and look at the front engine cover for major pitting -- else wise, it is the coolant in the oil that has been explained already -- but there are other sources for coolant intrusion -- cavitation is not common on the 6.0

Pretty simple, that would be coolant in the oil.

If you are paranoid about this, pull or have the water pump pulled and look at the back of the cover.

6.4L cover.

It ain't like the 6.0 has a low coolant pressure history.

It’s not good maintenance ……. Unless you have a coolant in oil issue seen on the dipstick, a leaking water pump, or an over temp issue where the impeller came loose. Otherwise it’s a waste of time and a good water pump o-ring.

If this was a 6.4L, OK.

this, what Jack said ^^^^
@jack or a leak out the seal weep hole

I have a wrench set that fits an air hammer -- but other wise put a wrench on the nut and give a tug, it may not be all that tight
Dont forget , turn in the direction of normal rotation, so in the case of the 6.0 to the left

You can use a large blunt punch and give a good rap on the left side of a flat on the clutch nut, to jar it loose

Oil on coolant (in the degas bottle) is a different problem. Typically oil cooler or oil cooler gaskets.

Some aftermarket delete kits are prone to leaking no matter what you do. Not an engineer bone in their body.

Cavitation behind the water pump impeller is a design fault of the impeller, which the 6.4L has. The two OE 6.0 water pump impellers do not, the early generation had too small of a hole in the impeller, which when pressed onto the shaft caused stress and in-service cracking. But both pumps designed by AutoJim (Jim Crider) never had the issue.
