Following up on Dukie1877's recent experiences, and a few of the other threads involved on oil pressure problems, do any of you guys in the know (cheezit, m-chan, vloney etc) recommend maintenance on this item?

Mostly asking for those of us with high mileage engines.

What are your thoughts on removing it once every 100,000 miles say and cleaning / polishing / wiping / sanding / using brake cleen / or other ... to the spring, piston or bore?

When it goes back in do you use thread lock / antiseize / teflon tape / nothing?

Anything else someone should know about removing this thing and replacing it ... any tips or surprises, or straight forward?

Thanks.

 

180K and never had mine out even though the engine has been out 3 or 4 times and heads done 4 or 5. It does have an annoying drip but works like a turk. I say let sleeping dogs lay unless you have a problem.

 

You're probably right, but I was figuring that with 240,000 miles I'd rather be cleaning it on my schedule instead of having it bite me in the *** when I'm miles from home at a job site. Especially as it seems like a lack of cleaning maintenance has been what has caused them to stick in the recent posts.

 

They seem small enough. Maybe changing them every 100,000? I guess small doesn't always mean cheap.

 

I wouldn't just replace the part at 100k. Maybe 200k miles, but probably not even then. The injectors are more likely to fail after 200k than the LPO regulator (at least IMO).

 

Does anyone know if it's even a separately servicable part?

 

My thought is regular oil changes and OEM filters. Clean oil equals zero sludge in most cases. Esp. if syn. is used. Less coking in the high heat areas such as the turbo.

 

Well when it gets warmer I'll be removing mine. I haven't decided on replacing or just cleaning it yet.
I've been reading more about it and came across the following:

The bolt is part# 3C3Z-6C751-A and I've seen it priced from $20 to $35.
The o-ring is part# W302722, can be bought seperately and I've seen it priced from $0.26 to $0.70.

The descriptions I've read suggest it is removed with an 11mm allen wrench, and there will be a small amount of oil that comes with it, but not much. The engine doesn't have to be drained of oil to access this part. Once it's out it can be checked for burrs and oil build-up, then cleaned with very fine cloth. Crocus cloth was mentioned in one instance, super fine steel wool in another.

One thing that was surprising that you don't notice until you get into a google search of this 6.0 regulator, is:
* how often it ends up being the root cause of a no start.
* how often threads have proceeded with guys going nuts on STC, HPOS, dummy plugs, etc, only to come to this valve last.
* frequently it appears as a suggestion in the thread early on, but it doesn't get much notice and the poster proceeds with the STC etc until coming back around to this valve.

--- 'how often' and 'frequently' are my own propritary terms to describe my exhaustive google search results ---

I figure being that I'm at high miles and my work route can see me making 8- 10 starts / stops per day easy, it maybe should be part of some maintenance schedule. Especially if it can strand me miles from home.

 

they dont seem to have to many issue. the only one I have run accross were on 03/04 pumps that the high side pump ball gets blowen out of them. Some of them will get stuck
