L18 8.1L swap resource thread

One of the first things we did to mine in the Green Camper Truck. Seems to work well for me.
 
Pulled the driver side plugs. Lots of crud on the insulators and ground straps. Is this the poor PCV system?

Copper, Platinum, or iridium ?

Question, for one of you guys that have worked on the Workhorse series.
Did these trucks ever come with Hydraulic pump, in place of the power steering pump?
I ask, because, I have a small bracket that bolts to the AC/PS, or, Alternator/PS, bracket. It looks like it would hold a Hydraulic pump.
 
I have no idea. The kid I bought truck from was second owner.
He changed the oil. Not sure he had it long.
I found 1 repair order 2013 at 110k miles for a fuel pump.
Has 137k now
 
I just want to say thanks to all of you who have contributed to this thread. I have been reading it for a couple weeks now. Such an amazing resource!

Here is my Project that you all are helping me with....
First, NOT a GM......It's better!!:saweet:

1965 International Harvester Travelall Panel/Delivery
Will be doing a full GM swap!
8.1l , NV4500, 203/205 Doubler, 14 bolt full float rear, 10 bolt/D44 front, on 37's.

I have all the big parts, engine, axles, and I have an Allison 1000 (original plan) that will be selling to fund the NV4500.

I was looking at one here last week to do the same.
I always liked the travel all, even before I saw a chevy truck

Here's the medium-duty layout with an air compressor for air brakes.

Some medium-duty and Workhorse units used a larger ZF power steering pump in place of the standard Saginaw style of the lighter duty trucks still using the same bracket on the left in the pic. Some used an even larger ZF pump but the bracket differed to match the pump. Shown on the right.

I think I got the little bracket on the left. I'm going to use it for a Hydraulic pump, for my full Hydraulic steering...

I think Larry tried to use the smaller of the two ZF pumps on one of his two trucks and if I remember right it interfered with the squarebody frame. But if the pump you have doesn't hang as low as the ZF unit does it could work.

Is that air compressor iron or aluminum?

It seems that would be a better solution than the yorks that aerate the oil into the air, but if it's iron, or too expensive, it kind of kills it for me. It also looks to be a lot deeper.

I’m not sure if he compressor is iron or aluminum but given the application I’m betting iron.

I’ve only seen one of these in person and that sucker is huge. It rivals some larger home compressors for sure.
 
Most all airbrake compressors are cast iron . Pump whole time engine running no clutch drive . Max around 125psi but 11- 15 cfm . Engine coolant flows threw for cooling . Oil feed for lube from engine .
 
Wow, that seems like a waste of fuel to pump air the whole time. Also sounds big and heavy, nevermind. Thanks for the info!
