Just Fishing's 09 Tahoe Build thread

[Just Fishing]

I was always told to use cheap conventional oil when first firing them off? Maybe it doesn't matter anymore but thats what I did on my avalanche. Cheapest conventional they had at walmart and an ac delco filter.

Yeah, knowing that you will only run it for 10-20 min before changing the oil.

I had this on hand, and i don't plan to run it in the future.
So I'm more than happy to use it up..

Stuff cost me like $15 a gallon, so i used it while testing the thrust bearing knowing i was pulling the engine once i was sure i wouldn't destroy a new crank.

Yea, I ran mine about 20 min total then changed the oil.

I just bought some High Zinc VR1 for my lawn mower and pressure washer lol

Well I fired up the hoe last night.

I had tried to spin the engine with the starter and no plugs to get an oil pressure reading before.
Ran the battery down trying.

I finally decided that i probably just couldn't get enough rpm.
And last time i used straight 30 weight...

So i went with install the plugs and fire it up.

Running i Didn't get any oil pressure, so i started wondering if i forgot to reconnect the pressure sensor or something.

I listened for a sec, then decided that yup no oil flow.

I played around with the oil cooler lines, confirmed no oil in there.
So i used my prime tool to force oil in there.

Anti drainback in the filter fkd me but atleast i got a little more oil to the top end.

Few more tries and i decided i had two choices.

Level the engine, pull the filter and prime the pump through the filter inlet.

Messy, but the last time i did that it worked.
Hard part is i need to have the tahoe sitting so oil won't flow out while i struggle with the filter.

Other option,
Pull the power steering mount and do it right.

So i went with that.
I pulled the plug and found it totally dry.

Weird since i already primed it once...

Oil pressure achieved.

I did run this longer than i had hoped w/o oil flow...

Hopefully I'm not doing this crap again lol

Today the task is to finish installing a few things under the hoe, dump the antifreeze back in, and do a heat cycle and change the oil.

Then the fun begins, crossing fingers.

I also created a new tune for the 6.0

I recall that i had never ran a "write entire" until the last flash where i started running super rich.
I did an o2 sensor replacement about that time frame as well.

The more i learn i decided I'm better off starting with the stock 5.3 tune, but with the displacement updated to reflect the 6.0.

Right off the bat, it doesn't smell as rich.
So I'll keep that as my base tune for now.

Only real concern would be the timing table.
Comparing the other sample, the 5.3 tune goes higher under load and rpm vs what i have been using.

I didn't look through the other tables that would change it, so i assume the real difference will be there.

Working on motivation to get back to work.

Biggest pita will be with the coolant.
Right now it's in a 5 gallon bucket.
No spout, so I'm expecting to make a mess.

I'm tempted to see if i can't find a lid with the spout, but i doubt I'll bother... lol

Cut an oil qt bottle, and use the top as a funnel.

If you can't find one with a spout, just get a plain lid (with a seal) and drill/cut a hole in it. If you're already at the hardware store and you wanna get fancy, you can get watertight fittings and a length of hose and make a lid with a spout. I'd prefer those few bucks and minutes of labor over spilling and wasting coolant everywhere.

 

[Just Fishing]

I recall the local grocery store had the spout lids a few weeks back, I might head on over there, assuming the S10's battery didn't die.

and I also let the registration lapse on it... lol

I'm thinking about just cutting a slit in the lid, maybe i'll get creative with it.

Important thing first, get all of the things done that require me to get under the vehicle done first.
Like I forgot to reinstall a heat shield on the side of the transmission.
the plan was to fill the transmission, and then see if the dipstick tube seal is leaking or not.
But I did remember to reconnect the line pressure gauge.
I have nice solid steady pressure there.
I also got a reading during the no spark plug cranking, that made me feel quite happy.

Took the hoe for a little drive today...























It went pretty well, after a few shifts the transmission started firming everything up.
I'm not calling it gtg yet, but the shifts are "pleasant"
So I need to reduce some slippage allowed in the converter, and up the pressures in the converter a bit after reducing the allowed slippage...

And for the life of me, I can't get back to the menu where it allows me to do the transmission fast adapts, where it runs the clutches and you have to hold the brake while it does it's thing.

I got it to do it once with the knock off tech2, but it's no longer a thing apparently

Oh yeah, so far with just the single transmission cooler, my cooler line pressure is much lower.
Before i was getting about 75-90 psi with the coolers bypassed.

Now I'm getting 35-50psi
I expect it to lower slightly once I add in the radiator cooler, but probably not by much.
