Hemi won't start, dropped valve? Blown engine?
I've read these types of posts before, and hoped I'd never be the guy on this end of it.
My 2006 XK Hemi 4x4 has 116k miles. I religiously change the oil, and changed the plugs July last year.
I got in my Jeep on Thursday, and drove 10 mins up the road to pick up my son from school. No issues. I parked, went inside, and came out 5 mins later, and the Jeep wouldn't start. Turns over fine, tach shows rpms while cranking, but no idle. If I pumped the throttle, I got maybe 2-3k rpms before it died again. I checked every fuse, then called a tow.
Yesterday, the shop (independent) called and said they think "there's something loose inside the engine", and they I'll have to replace it. Quoted me $3700 for the engine, $2000 labor, $500 misc parts, and $590 tax for a grand total of $6890. OUCH!
The mechanic said he DID NOT pull the heads and scope the cylinders. He said it would just be a waste of time and money on my part. What do you guys think of this?
After reading up on it, I'm guessing the valve dropped into the cylinder. Seems like a common source of catastrophic engine failure for the Hemi. What do you guys think?
Either way, I will be getting a second opinion. The mechanic said he won't charge me to store the Jeep for a week or so while I figure out what to do. Luckily, I have a car I can borrow.
It's hard to justify spending $7k on a maybe $10k Jeep, no matter how much I love it.
