Can anyone tell me what this area is for. Also why i have such a thick buildup of what would appear to be sand/light rust/dirt/granule material.. the one side shows flywheel, the other is that the water pump?? Should there be coolant flowing through this valley??? Stumbled upon while fixing stock connections from hose to EGR to Thermostat housing that had burst, again.









Last picture is what i proof when i say i know this engine like clockwork because of tearing it down and rebuilding it around 15 times now. Removed supercharger without having to unplug and or drain any coolant. Thermostat housing stays and all hoses connected. It’s a lot quicker of course than removing alllllll of that because the one thing that slows me down every time is the valley hose that connects to the thermostat housing, the smaller one.

Anyways back on topic. The very first time about a year ago i had replaced my crankshaft sensor because of a no start reason and rpms weren't fluctuating with cranking. If you guys know the area the bell housing where the sensor sits in also has a rubber guard or plug. When i had removed it originally water came running out, (car was filled with water replacing coolant at one point) when i removed the crankshaft sensor more followed until all was drained. Don’t remember if water came out while actual coolant was in the system or water, anyways. Hasn’t happened since. I have no idea what so ever how water was able to build up inside the engine like that. Unless you guys are able to give me info on what that valley is for and if it’s normal.. Thanks

 

As for the super charger Snout and pulley fitting through the thermostat manifold.
this will only fit through if the pulley is an upgrade pulley.
I.e 1.5 2.5 or 3pound upgrade pulley .
as the replacement pulleys are smaller than stock .
my previous 1.5 powerhouse Stainless stainless pulley
only just scraped through .
and in my opinion is worth doing the upgrade for that reason alone.
as it does make the job a whole lot easier..

as for the sand in the block.
remember the block is cast in sand.
May be some Excess uncleaned casting sand from
Friday afternoon knockoff build thing .
or worst-case river sand.
It seems way more excessive than what mine had in it,
I would be looking in other places like chassis rails
and for other tell-tales to rule out that.
especially after noting water in the Bell housing?
Sure hope not.

BTW this compartment is a brace For the block.
and sound deadening all in one.

 

hi
that void is just a casting area, looks like the dirt is coming from the flywheel area, do you have a cover off the bottom of the flywheel
also the valley pipe that fails its always the larger part, I fitted a new hose, but replaced the larger part with a silicone piece, 5 layer of reinforcement where oe only has 1
cheers

Chasis and other parts of car remain very clean. i’ve never seen this substance before anywhere in the car. Yes it is very excessive. I have driven the car quite a while in the dry season with the under body for that area off but could that really be from that ? How would it get in there ?? Datsports my friend, it’s the normal pulley lol. You have to pull the supercharger all the way back. Then at the point where the rear bolt triangle bracket thinks just touch’s the bottom metal of the windshield lift straight up and pull towards windshield.

Stock pulley. You’re not kidding though makes the job a whole lot easier out of many many times taking it apart this is the one time i said “we’ll lets try this” barely makes it through and i testes putting it back in as well😅

But as for valley okay that makes sense. Yes water coming from there the ONLY way i may be able to see that for a little bit i had my windshield Wiper cowl off the car and the engine covered in blue tarp. Maybe that gap with rain caused water to run down the tarp directly onto the housing somewhere where it built it up.

 

I have tried to remove the supercharger with the stock pulley way you describe.
there was no way mine was going through there. Trust me.
With the 1.5 pulley I had , it was very tight and scraped the casting lines of the manifold.
What OS diameter is your pulley ?

As for the rain thing I would doubt that very much.
if it hasn’t been in a river or flood then it was in there from factory.
shame they didn’t signature these engines like the Mercs.
you could’ve gone door-knocking.

 

"Yes water coming from there the ONLY way i may be able to see that for a little bit i had my windshield Wiper cowl off the car and the engine covered in blue tarp. Maybe that gap with rain caused water to run down the tarp directly onto the housing somewhere where it built it up."

This could be a likely reason. I had my windscreen cowl off for ages while I was changing over the valley hose and re-insulating the cowl.
We had a dust/rain storm and I was surprised at the amount of red dust that had formed after the rain that got in had dried off. Most of it though only towards the back of the valley where the rain got in. Fortunately no damage and I did have all the holes well plugged but learnt my lesson to well cover the engine with plastic, especially with the cowl removed.
If you had the tarp in a certain way it could channel water to this point. Plastic/tarp needs to be secured in a position where it drains anything away from harms way.
I noticed in your photos that your supercharger cooling fluid bleeder is flapping around/broken away from the intake manifold.

 

i have my two coolant systems
separated with an intercooler header tank and capacity tank .
the header has a port for the pipe which basically
puts it back to standard but with the extra capacity. Extra pressure/recovery cap and overflow reservoir.

the pipe was redirected to pressurise the intercooler Circuit .
but the circuit pressures itself fine cycles coolant to and from the reservoir .
and The pipe ended up Redundant blanked
not required.
keen eye 👍
yes it’s still like it . May remove it one day .

 

actually I think Joe is right.
You can see the flywheel through the casting holes In one of the photos.
it would make more sense and seems plausible to have come from down there .

 

Thats exactly what i thought it channeled the water off the engine down towards that area. it’s been gone since then so. Can i vacuum all of that out???

 

Yes for sure vacuum it out .

 

Just vacuumed it out. Datsports is that my water pump ? sure lines up with it. how does coolant not get in there.

 

How do i do that?^ Which one isn’t necessary

 

stock pulley no snout grind nothing

 

Should there be oil in there ? is that normal ? what sensor is that also MAP? I’m worried about the oil always coming into contact with it

 

There is going to be oil in the inlet mainfold due to the closed crankcase breather system.

The sensor in question is the MAP and should only be cleaned with products designed for that purpose. Do not use brake cleaner or other solvents.

 

Before reinstalling the supercharger, it may be a good idea to also replace the knock sensors since they're now accessible.

 

yes there will be oil throughout your intakes . As NBcat says it’s inherent of the design due to Stringent environmental laws.
you Can severely reduce that or even eliminate it with a oil catch can on the PCV system.

they are all necessary.
Unless you modify the ic system.
If I was you I’d leave it right alone until you understand the systems and can figure out your own way to modify systems if you think necessary.
though with a stock pulley you have no reason to upgrade your intercooler system.

 

Even if they’re okay? i have the engine like this at least 3/4 time a month i’m always doing/cleaning something so there’s always an opportunity. What would failed knock sensors show signs of?

 

It would be good to know the signs of a bad knock sensor.
I was a tight **** and only changed one item when I replaced the valley hose. The lower gasket of the EGR assembly where it meets the exhaust manifold as it looked suspect. I'm keeping a keen eye on things but everything else in there looked in excellent condition. The large convulated plastic air tube's click on plug to the back of the superchargers inlet elbow has a limited lifespan. It sealed back well but I was tempted to replace it with rubber but was unsure how rubber would perform.
Knock sensors aren't exactly cheap getting them here in my rip off country.
After the experience though you become very familiar, more confident and miles quicker the next time around. All be it a bit more lazy.
I did however take the supercharger in to the experts for a oil change and check-up/service.

 

A bad knock sensor throws a code
and gives you a restricted performance issue .
i have been under there several times . And never replaced mine .
though I can see why you would replace them if you never want to lift the blower again .
its not cheap but , it’s not bad advice.
