Mostly mine own fault it's taking too long. I was aware that the first LQ9 I had bought wouldn't turn 360° by hand. Tore it down and found #6 connecting rod bent. Replaced it with a new one and put a new injector on that cylinder figuring the injector must leak and caused hydro lock. Started it up when the swap was completed and the engine literally exploded. Both 7 and 8 rods were gravel and a piece went thru next to the new starter ruining it and the block.
I then bought an 05 Gen4 LQ4 since LQ9's were hard to find. Put it in and it started ticking. Pulled it out to find #8 rod was bent, just a hair and the piston was just scratched by the crank. Gonna put the new rod from the LQ9's #6 in the #8 piston and will clean up the skirt with a file. Then sell it on Facebook Marketplace. My idea of pay back.
Bought a 3rd engine, another LQ9 from LKQ and started installing that when my mind ran out of gas and I took last summer off from it. Just last week got it together using all the injectors from the 05 LK4. Going to do an individual injector test with my Tech2 and a fuel pressure gauge before firing this one up. But the bottom just fell out of he thermometer and I'm not going to work on it until it warms up. No fun, even with a space heater in the shop when it's single digit highs. I can only just get it up to the 30's inside when it's that cold. A 20° gain when it's in the 30's I can handle. At my age 50's is about the lowest I can tolerate for long. I also don't want to start an engine that has sat over a year when it that cold. I think temps in the 70's would be less apt to cause unnecessary wear.
LKQ gave me a 6 month warranty on their LQ9 and a copy of the accident report verifying the miles on the motor and a pic of the rear end damage to the Escalade. So there's no doubt it's a good engine.
May probably.
That's life here in the Frozen Tundra. Stay inside from December thru April by the fireplace.
