MrToby ... That post was so long I had to hire somebody to read it for me!
That engine probably blew because the guy before you ran it out of oil, not because you didn't do 3k oil changes. Right?
Heck! How do you think I feel? I had to go back and edit it three to four times. It's a mini novel.
No, I don't blame him. I think it was a combination of both. I'm sure he started a lot of the coking up the oil and the varnish and what I call peanut brittle in there by running at low all the time and plus it was a super stretch 36 foot long Excursion limo so those things idle all the time.
So I'd say It's a combination of both but I certainly didn't keep up on the oil changes like I should have.
But like I said, all in all I'm ahead of the game financially and was paid well for my extra 9 or 10 hours of Labor and doing the engine swap.
I will admit but I changed the oil properly after that.
I just pulled that engine and sold it a couple of months ago because I was parting out and junking that vehicle.
