Six pages of garbage and wasted band width. I guess you guys have nothing else to do. The Amsoil war has gone on on different web sites since the web has been around and its always the same old thing, those who swear by it and those the swear at it. All the dialog is a waste.

You seem to enjoy reading it and posting on the thread.

(Charge Air Ducting and Boost
Pressure Control
Both the boost and intake pressures are
used to control the wastegate of the
turbocharger. These pressure signals are
supplied to the ECM, which then sends
a pulse-width modulated signal to the
Wastegate Bypass Regulator Valve N75. As
a result N75 controls vacuum supply to the
Pressure Unit, which directly acts on the
wastegate via a connecting rod. This control
system regulates the turbine speed and
sets the maximum boost pressure.
If the control system fails, the
boost pressure acts directly on
the pressure unit. The increased
spring pressure reduces maximum
boost down to minimum boost.)

This particular article deals with the VW turbo. I have yet to find
any positives on the kj. But I am assuming systems are similar.
So that little solenoid with the filter hanging down, looks to me like
it is very important to our system for boost or underboost.

You guys wanta fight and bite, but this above is still un-answered
Right above the passenger wheel is the vacuum solenoid boost sensor.
What does it do>

With all that garbage why cannot I get a reply from someone on this topic?
The boost sensor resovair filter?

You have posted this excerpt several times but no one knows what you are asking.

I started this post and now I am sorry I did it.

I just went looking for gear oil locally and was having some trouble finding
what I wanted.
So I have ordered some and will try it. If I don't like it, I can divorce it. No Biggie.

I do apologize for ever starting all this.

I am requoting myself again

Come on. This is fun. No one really takes it seriously. It's a good way to practice your typing skills and once in a while we all learn something. Besides; no self respecting automotive forum is complete without an oil discussion. If someone doesn't like reading about oil then why not just skip this thread?

The engine parts never reach that temp but they are subjected to momentary spikes of those temps,as is the oil-----------cylinder walls,combustion chamber,valves,and pistons.

Very simple.
What is the connection to this solenoid to the engine?
What else can I say?
Is it part of the muffler system? NO. Does it control
the steering? NO.
IT is a part of the basic CRD system and I would like to
now what it's function is.
I don't know how much simpler to put it.

Just for the record, I have thoroughly enjoyed this thread. I'm not particularly technical but have followed the debate and learned something from the more technical ones on both sides. Thanks.

Just to clarify many parts of your engine that have a oil film on it does see temps into the 4000 degree range the whole time the engine is running.

Quote:

Pour point: When was the last time that you tried to start a vehicle at -54F, the rating of Amsoil's closest competitor? These temps will never be encountered in the lower 48 and even if they were no diesel will start at that temp no matter how many times you cycle the glow plugs. Test useless.

Not really in the lower 48 but Alaska does see those types of temps.And yes a Diesel will start just fine in those temps(no glow plugs either),I know I spend 3 months cold weather testing the Marine Corps new 7ton trucks in Alaska and saw those kinda temps very often.Used the cheapest 15w40 diesel oil(goverment bought).

Oh the longer the oil is used in the engine(with proper filtering) is actually better then changing the oil every 3000miles.The longer you run the oil the smoother the molicules get providing better lubrication,but proper filtering is needed.

And no I don't use Amsoil(I have when can be found locally),I normally use Mobil 1(helping Exxon make it's 39 billion a year profit).

Interesting observations in Alaska. However, for people in milder climates these temperatures mean nothing to us. I usually don't go on the annual polar expedition with the KJ, so I'll be ok.

Regarding the temperatures. I get your point, however, I need to put emphasis on the fact that the oil itself should never rise to 4000 degrees all together. Well maybe it does in very small quantities, and then it explodes, just like the diesel fuel. Problem solved

Problem then is if the oil explodes along with the diesel fuel, you might get a little problem when there is nothing left in your oil pan. It would probably be adviseable to change to a better oil which can stand higher temperatures

Ah - the filtration part. I thought the particles which the oil kept in suspense was so small the oil filter would not filtrate them.

Also why do we then have change intervals? If filtration is all you need? I mean - why not just change the filter (needs a re-design of oil filter location

).

What about the talk about the additives to the oil which allegedly is broken down and reduces the lubrication characteristics of the oil? Can filtration help?

Ah hah! now we have a question instead of a statement. See this article http://en.wikipedia.org/wiki/Boost_controller . Our KJ does not have a waste gate but the same principle is applied to the VGT. If to much boost is detected the solenoid opens the vacuum valve up so that the turbo housing vanes are parallel to the flow of exhaust flow there by reducing how much air the turbo can pump and protecting the system. see this article. http://en.wikipedia.org/wiki/Variable_g ... rbocharger I hope this helps.

By the way this is not the appropriate thread for this topic

Maybe your not getting a response because no one has had one go bad yet :shock:

On a VW the Garrett vnt is operated by vacuum and I "assume" the crd's is the same. But one end of the filter is open so that looks like a intake. But that that does not make sense to filter the air going out?? In short I've not looked at it well enough to determine it's function and have not found a vacuum pump yet. My question to you is where's the vacuum pump :?:

You stated first that engine parts are continualy heated to 4000F, but now they are subjected to only mometary spikes of that heat. Even if they were, So What? Any kind of oil would erupt into a ball of flame if heated to 4000 even for a split second. You would then have metal on metal, not a good recipee for engine life longer than five minutes.

I wish that some military grade fuel was availible gas station pumps but I don't know if I'd want to pay the price.
BTW I think that you have the coolest avatar on the forum.

You can't or don't know how to answer this question?
I have loved this forum but up to know, I think a lot of it is
bull s%%t. My simple question in for the forum about the vacuum
solenoid boost and it's filter.
Yes, I have asked it for at least 4 times or more and apperantly
no one has the answer to it.
It may have something to do with the OS of the KJ or may not but
either way, I don't need to hear you say you and asked this before and they don't
know what you are asking for?

Woa there fella. calm down. Your initial post was this...

"Charge Air Ducting and Boost

No where in there is there any kind of question. Personaly I wondered why You kept posting that statement in inappropriate threads. If you have questions about the KJ this forum is the best place to get them answerd but no one here is a mind reader.

Just curious, but is english your native language? I am wondering if there is a communications gap here, because the title of this thread has nothing to do with the question being asked...

Amsoil is supposed to be a very good oil. I am looking at dealers
in the area. It looks like The Avon Lady. They all work out of the house.
I can order On-line or thru a local Forum member and have it shipped
to me.
My question I guess is? Why is this?
I was ready to order, and am thinking. Why is this, this way? People
should be shouting for this product.
I need diff fluids soon and wanted you'all imput on this.
Thanks

Actually this was your first post, and so far the discussion is appropriate to this post....
