2015 e63s engine sound

Can someone give me a pointer to as if this engine sounds healthy or not? Looking to purchase this week it’s a 2015 E63s with 84k miles.
I had a PPI done last week. Valve cover was seeping oil out of it. But they never did a borescope for the cylinder walls.

high power turbos on stock oil...

> 1st step:
I've listened to your short sound clip. It sounds okay as in "no VVT actively rattling"

The busy ticking is normal work of Bosch piezo direct injectors under 2500.Psi.

> 2nd step:
inspect maintenance records and repairs.
in particular tranny ATF, Sparkplugs, Diff/4M

> Next Step:
It's what you can't see that's important: cylinder walls in this case.

Get a PPI with cylinder borescope BEFORE making any commitment.

Any sort of decent warranty coverage a plus.

I had a PPI completed last week but they never used the borescope. The valve covers were also seeping oil and the rear subframe has a hole from rot in it. I call my local Mercedes’ dealer and was told it’s replaced for free, from the extended warranty.

Valve cover seeping oil is associated with high-heat means...
CHECK CPS for "$10k-OIL-IN-HARNESS" !!!

PPI needs to be realistic... not just "tire pressure and dents".

Remember that parts are cheap but labor not so much.

The seller wants 26k, do you feel like it would be a risky buy?

It sounds under maintained for such an expensive engine. You must horoscope. It doesn't matter if the first place did not do it, you need to find someone to pay that will. Warranties exist but why start with a dud.

your call... it's only money!

Even with a "free car wash" you still need to know about engine condition before comiting. Its 100% legitimate before you get handed a surprise repair quote.

Just to illustrate why everyone emphasizes the boroscope inspection; otherwise, you may get a paperweight

I saw that as well, what do you think the stored codes for the engine are? I thought low battery voltage but I’m no expert. Could that be a reason for the monitors not being ready. Also I’m having him take pictures of the cam position sensors and the ecu plug. So I can see if there is oil making its way to the ecu.

I want to hand out credit where due :
So far nothing's screaming run ie. good!

M​​​​​​eaning this appears like a good purchase if every checks out ok. The little PPI is seriously to restrictive.


Granted any used MB is going to require maintenance for sure - These cars luv TLC.

There are no active big money faults that I could see. Only average wheel TPMS, no big deal.


> WIN-WIN Advice:
-- To show your honest interest... agree to pay for a sparkplug job and DETAILED BORE-SCOPE REPORT of each cylinder. It's duplicate labor!

-- If fail you pay only labor + no parts.
-- If pass you pay whole job + car purchase.

sensors are good

Cyl. 1+2 are usually first to ring out

There are CPS units to see.

yes, exactly!
We want to inspect cylinder walls not just a random single piston top.

Inspection is not about twisting anyones arm ... it's a $25k+ purchase.

8 cylinder walls numbered so you know which your looking at.

At the point you commit, you'll own everything as-is.
Last step will be hearing no cylinder misfire after reassembly.

+++ What's your thinking, JC?

he said he’s working on getting a borescope on cylinder 1. That’s what I told him too I asked him to do another. Should I have him send another video too afterwards?

The engine must be rotated (by hand) and the camera shows the cylinder completely from top to bottom, The scoring is mid-> bottom of the cylinder, With the piston at the top, the scoring if present is hidden.

here major scoring

what do you think would be the better purchase then? I have two cars lined up. The E63s I’ve been talking about which is located in Maryland and then a 2010 c63 P31 that is located locally in Massachusetts and I was able to test drive. The head bolts have not been replaced with the new style. The c63 has 54k mikes

I think I’m going to go with the E63s over the C63 and just buy an extended warranty. Do you recommend that? I talked to one this morning and it’s basically a bumper to bumper. They cover anything related to the engine, transmission and electronics.
