And I second @MexicoBlueTurboS. ****ty situation and we are here for you.

 

You're hearing the knocking sound in the second half of the video too, right? That's the noise everyone is worried about.

 

Thanks @TheBruce - that is a good point, though one that I'm not qualified to comment on - anyone else have insight as to whether the top portion of the cylinder would need to be affected to produce the noise? If that's the case, it would seem odd that the report came back as having had a clean scope of the upper cylinders all around. I do not believe that they checked the water pump or fuel pump...he did stipulate that it seems to be coming from the driver's side, bottom...

 

Btw - do you know if this mechanic is reputable/knowledgable? If my indy gave me an email like that I would rip their face off. I dont feel its a) thorough or b) professional. I would not be comfortable paying anyone for 12hrs labor after the report they sent.

- My first recommendation is take it to another shop.

- Second recommendation is have them watch this video from Jake which walks you through how you can get a pretty good indication which cylinder is effected before you even scope it, just by using a mechanics stethoscope.
- Bore scoring knock is heard prominently when the car is on a lift and you are near the cylinders. In your video the noise is loudest at the driver side rear, confirmed by the mechanic. Thats the location of the water pump and fuel pump. I have no idea why they wouldn't have inspected those closely, or at least told you they ruled those out.

- I would ask them for a video where they have the car on a lift and take a mechanic stetascope to each cylinder, the fuel pump and the water pump and register where they hear the most noise.

 

Also - I’ll get pics of the cylinders and share

 

Thanks for the insight. Again, given the amount of work and the deadline here, I’m not sure I have the option of going somewhere else. By reputation this shop is very good...

 

Understand. Ok so have them confirm they watched Jakes video and then give you a video what they hear from each cylinder, the fuel pump and water pump.

I sent a note to my indy to see if he has any ideas.

 

Thanks again. I'll take any insight I can get here.

 

OP - This is a simple enough fix that you might ask them to replace it. I'd think it's at least worth trying prior to spending a lot more just on diagnostics.

 

Sounds like you are dead set on the 12 hour inspection. No it does not take 12 hours but it does take a few. Call around and get estimates and bring back to the shop to show them they are ripping you off stating 12 hours. Use that as a negotiation tool.

 

I appreciate the input. I’m not ‘dead set’, I’m backed into a corner given time constraints

 

Only takes a couple hours to get estimates elsewhere to show the shop it is currently at that it should take them less than half that time. They are taking advantage of you knowing you are under the gun.

 

I'm sure that you're right. I'll call around first thing in the AM to see if anyone can take it. Already called another shop this afternoon that said they couldn't get to it by Friday; didn't ask for an estimate however..

 

Yea I hear it loud and clear. As my post stated I've heard it before on my car. Thing is that when you try to listen everything's so tight in the engine compartment noises resonate, trying to feel around there is like putting your hands in Medusa's hair.

 

Pay the money and forget about it. The price of mind - one way or the other - for a few grand on a $50k car is worth it. If it is scored - great - got a warranty
If it's not - great - drive the car worry free
