2011 GT I think I have rod knock
I think I posted this in the wrong forum earlier...
I believe I have developed rod knock after a series of questionable decisions.
My primary question: is it worth it to replace or rebuild the motor?
I know this question is highly subjective, but I'm hoping someone can share their own experiences to help me decide what to do.
So I have a 2011 GT/CS 6sp that I daily drive. It has 149k on the ODO and it has been stock for all of it's life up until spring of this year when I replaced the clutch with a SPEC stage 3+ and SPEC steel flywheel. At that time, I also purchased a REV X by BAMA so I could perform the crank relearn.
I put their Stage 1 tune on around May. Around The turn of July, I got a P0349 - Camshaft Position Sensor A Circuit Intermittent Bank 2 and my research told me that it was actually a problem with the alternator. I was having headlight issues and battery issues earlier in the year so this seemed to make sense.
I got around to replacing the alternator two weeks ago (I used all Ford OEM parts - New, not re-manufactured), and cleared the codes using the REV-X. Two days later the code came back. I have ordered a sensor and it should be here soon, but I have continued to daily drive the car as it hasn't shown any signs of misfire or losing power. Today I accelerated more aggressively than I had been since getting the code and I start hearing the dreaded clak clak that I am convinced is rod knock. The sound appears around 2K RPM and gets progressively worse with the revs. I will have the car towed to a mechanic to confirm my diagnosis tomorrow.
I'm fairly well experienced with replacing engines. I've swapped 3 motors on 90's Escorts and I've had the motor in and out of my 02 WRX more times than I can count. I'm not shy of doing the labor of installing a motor in this car either.
My biggest concern is that this motor seems to be incredibly expensive relative to the car, at least from a quick google search for replacement motors. Long blocks seem to be in the $5-8k range, and I haven't seen anyone selling a shortblock with rotating assembly (any suggestions?). Short of that, I would also be open to having the motor rebuilt, so if anyone could recommend a shop (preferably close to central NC though I'm not opposed to freight), I would greatly appreciate it.
Thanks for your time and I hope I'm able to get back on the road soon!
