Update time....
Wow it has been a while (almost 3 months) A lot has happened, I will recap.
Just before Christmas I put a new (used) motor in my wifes 2005 Tahoe. Here are a few pics of the motor as I recieved it
This motor is used and has 75,000 on it. It comes with a 36,000 or 3 year warranty on it.
They go through the motor and test it. But I was quite impressed!
I pulled the valve covers for inspection and it was clean!
Out with the old...
Not a lot of room! I sure am glad I built my garage 28 feet deep.
Still not a lot of room! (never big enough)
I sure am glad I had a couple of helpers, (2 of my sons) They helped a lot! Love you guys!
here it is, a nice and snug.
I never did get a completed picture but you guys know what they look like.
The old motor made it to 199428, not bad considering it had (I believe) the infamous castech head crack problem. (the head develops a crack allowing coolant to get in the oil).
It never turned milky but would turn the oil into sludge. I was changing oil every 2000 miles. As long as I did that, the oil did not sludge. If I let it go to 3000 miles, SLUDGE!
WEIRD! I lived with it this way for about 4 years, until one warm autumn day we were one our way camping (towing a 28 footer) when I heard the engine beginning to knock. I check the oil pressure and it is below 20! NOT good. To make a long story short we get it home, I switched vehicles and we finished the weekend camping. I get back and look the truck over, and all is good, a bit low on the oil pressure but it ran fine! You would never know it had a problem. So now I don't trust it and I start looking for a motor .....
