New engine? What????

My daughter brought my 2005 Jeep Grand Cherokee back to my house after letting her haul a peice of furniture..
It was fine when she left. She pulls into the driveway and I'm gardening. The sound was a definite "Holy hell...WHAT HAVE YOU DONE to my beloved?"
I've had the same mechanic since I started to drive. I knew my baby would be in good hands.
I thought I'd stop by Auto Zone and see if it was an easy fix
(I don't work on cars, and it's very unfortunate).
A couple of misfire codes is what I got. One was about a valve spring.
After puttering and shaking my brains out across the bridge to Indiana...I got a call that this shop doesn't have the time to get to my girl because they are closing for good.
With a sinking heart, I told Wayne that I guess take her down the street to the other folks.
He did. After 8 days, dealing with a receptionist, I hear it's a valve spring. No biggie.
10 days later...it needs an entire engine. Parts and labor are more than the Blue Book.
Being a girl, I know better to listen to one opinion.
How could a misfire and a valve spring result in an entire engine?
Anyone?

Re: New engine? What????

So what really happened or what did they fix or replace on it? I believe u can claim it on insurance but it's an 05 so how much would it cost it all depends on what work they did

And what the Jeep is really worth to u

Re: New engine? What????

You will need to know what happened to the engine and what damage is caused. Sometimes a small failure can result in subsequent damage. Maybe you can go to an other place to get a second opinion first.

Re: New engine? What????

You definitely want them to spell out exactly what is wrong with the engine, and exactly what failed. That said, it is possible they are on the up an up.

When a valve spring/valve breaks the pressure of the descending stroke of the piston can pull the valve (or part of it) into the cylinder (known as sucking a valve). If the valve protrudes enough (or is broken and fully pulled in) this can cause a terrible racket (metal banging on metal) as well as damage to the cylinder wall and piston. The more the engine is ran after the failure, the worse the damage can be. If the damage to the cylinder wall was significant (ie more than could be bored out during a normal rebuild) a new engine block might be required.

That said, it is always healthy to be skeptical about what a mechanic says. Asking exactly what is wrong, and wanting to see the broken parts is a cheap/safe way to keep everyone honest.

Re: New engine? What????

Thanks for all the replies. I'm getting a 2nd and 3rd opinion after being on vacation and picking the Jeep up.
A rocker arm fell off...
Got another set of error codes from Autozone.
CO2 sensor and MAP showed up in the errors.
I drove it for a while and it was okay. Then it started to stall.
I tried to put in coolant and it all leaked out.
This is our only vehicle at the time. I'm the caregiver for both my elderly parents. I'm also disabled due to a bad back surgery. We are budgeted and have many Dr appointments. I'm taking it to the dealership to fix a recall and get a diagnosis from them too. I'm sure that will help me explain better since it is a Jeep dealer. I absolutely appreciate all of your help!!!!

Re: New engine? What????

Did the engine overheat recently? That a rocker arm falls of, can be caused by a bad hydraulic lash adjuster, a dropped valve seat or even a broken valve spring.
Can you see where the coolant is coming out?

New MAP sensor and new C02 sensor.
No different!
Going to the dealership tomorrow to have a recall fixed and will get a full diagnosis.
This should help.
It seems to not stall when I'm at a higher RPM so, I drove it ho.e on the Highway. Didn't stall until late a damn red light.
