My dad would put used motor oil in a 55 gallon drum. When it got full we would put it in the back of the truck with a big long spray nozzle he made to spray the oil over 8ft wide. I would sit in the back and he would tell me when to turn on the valve while we drove. We lived on a long dirt road. He did this to keep the dust down. Haha

This was in California no less. He still lives there and the road is still dirt. But looks more like the dirt track at a sprint car race at the end of the night. Hard and shiny.

Be VERY careful Mike........this sounds like a confession of wrongdoing or an accessory to a crime at the very least.

You never know when those "tree huggers" are lurking..........and ready to pounce !

LOL I am not worried. Pretty sure statute of limitations is on our side. That was 40 years ago. But I bet Sheepdog is typing a long response now about how i will go to jail.

Got some sensor blocks made to get all our sensors in a good place. Now that we don’t have hard lines we had to relocate our sensors.

These turned out pretty cool.

Smaller on is for Oil with two Electonic sensors and 1 mechanical sensor.

Large one is for coolant with 1 electronic, 1 mechanical, and a air bleed valve since it will be at the highest point over the engine.

Mike, I assume you know this but just in case anyone else reading this is not aware, you need to keep the steam vents on the ls motors functional. Air gets trapped in the cylinder heads and needs a way to escape. I'm not sure if the LT is the same way?

Here is a good article spelling it out- Why Your LS Engine Needs a Steam Vent Kit: 5 Facts About 4 Corner LS Coolant Crossover Steam Kits:

Our radiator is mounted up high behind our cab and I still always need to bleed the steam vents when filling the system or I can never get all the air out. I used -3 fittings on just the front two cylinders and tapped the other end into the water pump housing. Earls LS9809ERL EARL'S LS STEAM VENT ADAPTERS

We had another racer in our class last year who kept having overheating issues- turns out they had theirs blocked off. Maybe I shouldn't have said anything :D

Thanks for clarifying. And that was nice of you to help them. It’s amazing how many small mistakes can be made that ruin your race.

The LT does not have steam vents like the LS3. It’s internal.

This vent is for us to help bleed the system when filling. With our radiator all the way in the back and the cooling lines going down then back up it creates pockets for air to get trapped. With this bleeder will can run a small hose from this back to our expansion tank res, giving the air a easy exit. This would remain closed when being ran after initial filling.

We had a sensor in this same location that we would open to bleed air but it would make a mess. So with this we can keep it clean and circulate the fluid that comes out back to res.

Got the cooling lines In and ready to go.

Oh and we added the oil sensor block and mounted it.

Here are some pics of the engine side

what brand of zip ties do the pros use ?
1655222025647.png
1655222025647.pngThese are the good ones........finely ribbed body with a metal toothed head which allows for "fine" adjustments and no slipping.

Don't forget about the rounded corners on the head that won't leave you with bloody knuckles !

We use good ones but not the really good ones. We go thru way too many to buy the top dollar ones. Very few zip ties stay on that long. And there is never something that is held by 1 zip tie. Lots would have to fail to have any issues. We have yet to have a zip tie fail after it was installed.

You guys ever use velcro straps? Curious how they would hold up to the desert. Work fine for road racing. We started using them a few months ago. Only use them in the cab, still use cable ties outside the cab.
