Blown Engine?
I have a 2006 Charger 5.7L R/T. After rebuilding the engine and reinstalling it, I drove it around for a bit but soon noticed a loud ticking noise coming from the engine. After pulling the heads, I found that two of the lifter plungers were stuck, so I ordered new OEM lifters, installed them, and started the engine. Everything sounded perfect—better than it ever had—but while letting it run to allow the lifters to fill, I checked the oil and saw that it had turned white and was slightly over the safe level. That’s when I realized I had forgotten to change the oil after removing the heads, allowing coolant to mix in.
After draining the contaminated oil and refilling it, I restarted the engine, which initially ran fine. However, after about a minute, the idle began fluctuating, and within another minute, it started misfiring before dying. I restarted it, but the misfires worsened, the idle became increasingly unstable, and I had to keep my foot on the gas just to prevent it from stalling. Over the next ten minutes, it kept getting worse—dying, restarting, and progressively running rougher—until it finally shut off for the last time.
When I tried to start it again, the engine turned over for about three seconds before locking up. Hoping to free it, I put a wrench on the flywheel with a two-foot extension, but it wouldn’t budge. The next morning, I tried again, but it was still seized. I decided to pull the spark plugs and, after cranking it for a couple of seconds, the engine finally started turning again. Pouring some oil down the spark plug holes, I cranked it a few more times before starting it, though it felt like only four cylinders were firing.
I shut it off, removed the oil filter, and turned the engine over again, confirming that oil was being pumped. After reinstalling the filter, I attempted another start, but this time, it didn’t fire up at all and seemed to be firing on two of cylinders. Checking underneath the car, I noticed gas dripping from the exhaust.
I’m really not sure what’s going on—any help would be greatly appreciated.
