Steve, I'm betting some PO replaced the original Isolator with the solenoid. The solenoid was how things were done on earlier motorhomes. This is the one I purchased for my Argosy. Probably overkill but the one I found was about half of what this one is listed for. Shop around and I'm sure you'll find a similar deal.

I'd have to say your 345 is certainly keeping you busy lately!

Brad

Thanks Brad...
I have no idea what that does compared with my little tin pot thingy, I will add it to my list... Page 127...

My Birthday today, so I allowed myself a day off... well, after I did some measuring and prelim cutting of the MLV for the doghouse.

I did get my Holley FPR and gauge tho, so will need to figure out where it will go.
It says in the instructions that its not for use with a mechanical pump...
But since my system pressure is running 8psi with the mech and electric pump, I think it should work!

Progress.
Spent an hour at HD collecting fittings to get my Holley FPR ready for mounting.
This is what I came up with.



Which looks like this.



That done, I managed to pull off the drivers side banks headers.



They will get a makeover, fresh gaskets and an O2 bung in preparation for my Innovate Fuel/Air gauge.

The "EFE/Heat Riser" looks in grim shape, but surprisingly, it works, so I will give it some love too, and refit it. They are NLA or ridiculous prices!

That O2 sensor can only go just before the heater riser, right ??

I am planning to put it in the upper side of the header collector about where #3 cylinder comes in.

Photobucket was playing me up tonight...
here is the missing pic of the FPR assembly.

Ok, got it. Despite the fact that the temp will not be the same as it would be closer to head, you want to be able to sample all the cylinders on that side of the engine, which would really come into play when you use the O2 sensor for an EFI. I have read that the upper side of the exhaust pipe just passed the header collector is a good place.

The info says, in the collector, on the top facing down, so condensation will not pool in the sensor.
The word is that mounted as remotely as this is, it needs to be a heated 02 to work correctly, which might well be important for if I go with the TBI upgrade. Planning on putting a bung in the pass side header for that.

One thing I did do yesterday, was take off the noisey "flex Fan".
i have a Viscous coupling and 7 blade fan that was on my '87 Suburban, so will be mounting that tomorrow when I have the correct bolts.


This is what I will paint the headers with.


Also tried to mount the Smog Pump but didnt have the correct bolts.

This meant I had to remove the front closing panel, which will be getting some love... The scoop for the HVAC sytem is a cracked ABS mess, and will need a rework. I think a sheet aluminum folded scoop is coming.

Steve, your mention of adding bungs and their potential use in a TBI upgrade brings up an interesting point. I have Doug Thorley Headers (THY-303Y-C) and they do not appear to have bungs for sensors. These headers are ceramic coated inside and out. Is the abscense of bungs going to be a stumbling block for installing a TBI system? Or can the bungs go after the collectors?

Brad

Good question Brad.
My banks headers, are really long, and I was concerned about that.
It seems we dont need to be.
I am sure putting in in the section of normal pipe right behind the collector will be fine. The OEM TBI sensor is a 1 wire, and narrow band. It is normally mounted on the cast manifold, and as such gets plently hot. These newer wideband O2 sensors have a heater in them, which solves that problem.

Read the mounting instructions here...

Steve, thanks for the link.

It sure sounds like location isn't super critical as long as a few things are avoided. Looks like using the Thorley headers with TBI shouldn't be a problem either.

Whew!

Brad

Glad that put your mind at rest!
I was concerned about the Cat placement as the Banks system on mine joins both banks at the muffler. I looked up the later Banks kit, and it shows the cat being reinstalled behind the muffler!

So, on to my progress today...
My attempt to extract the 2 collector studs that didn't break upon removal, failed. They all broke regardless of penetrating fluid/heat and I resorted to what I do best, Brute force and ignorance!


They were drilled out completely and will be replaced with bolts and nuts.

Moved on to the O2 sensor install.
The bung supplied with the kit was quite deep, but the instructions state that having the sensor tip flush with the pipe is ok.


Marking and positioning..


Drilled the hole, and made it so the bung sank into the tube somewhat.


Decided I would TIG weld it... I am still learning and the "Stack o dimes" is NOT on my list of accomplishments. It is not gonna leak or fall off tho!



Done.


Inside.

Steve,

Will you be potting a window in the doghouse in order to read that gauge?

My Banks kit came with a bung already in the first short section of pipe that bolts to the left header collector. I ordered the fuel injected version of the kit so I would not have to plug the holes for the smog lines. Sorry I am away and can't get a photo.
