Is engine still in the car, or was it removed? It pains me to see a new car like that. Oh, and is it normal for pistons to be that dirty with just 1,300 miles

???

I didn't want to move any of his stuff around so I didn't see the broken spring (Saturday and the tech wasn't there). I'll ask for it Monday.

I thought the same about the buildup on the piston heads...anyone know if this is a normal appearance for 1300 miles? The engine probably ran for about 1 minute total after the spring broke (if memory serves me right but I'd have to think about that one).

100% of them do...for me.

So, it looks like they are replacing one of the lifters also (there's only one missing in the pic). The cam lobe moves the lifter which moves the valve, right? So why would the lifter need to be replaced? Or does it come attached to the valve?

Yes. I'm sure lifter was damaged. Since spring wasn't pushing valve stem against lifter, I'm sure part of the hydraulic valve lash adjusting mechanism (probably a shim) was dislodged and caused damage. Haven't seen one of those lifters underneath. Maybe you can tell me

.

Was the engine removed or in the car?

Hey, it should take more than 10 days after you dropped the letters to have your car ready. What's the status of that? Are you in talks with BMWNA or left all the talk to the lawyers? Good luck.

Engine was not removed.
BMWNA should have received the certified letter Friday. A copy of the defect notification form also goes to the office of the atty general lemon law research unit.
"After the manufacturer’s receipt of the notification, the manufacturer or its authorized service agent must have at least one opportunity to inspect or repair the vehicle. The consumer may be eligible for a purchase price refund or a replacement vehicle if the vehicle is out of service for repair for a cumulative total of 30 or more days."
Today is day 20.

Good writeup, PG. I don't think I'll be able to get anymore pics...I'll try.

satinghostrider · 08-08-2010, 10:37 PM

A guy with valve springs that broke.

Damn this valve spring issue could possibly be a weak link in the engines.
So i presume these 16 lifters are for the bank that was affected? Because I remember that we had 32 lifters in total for our M3.

Thanks for the info, but how the heck can valve lash be adjusted hydraulically without any internal parts? Oil itself can't act as a shim. I'd appreciate any info on how hydraulic valve lash adjustment works. Or is it just a gimmick??? Can't imagine all valve clearances being identical right off the bat; Do followers come in different sizes then?

Finally, can you comment on the amount of carbon deposits on that engine? Seem excessive for just 1,300 miles, and 100% synthetic oil, but maybe they're normal. Thx.

SuitedPair · 08-09-2010, 11:30 AM

First pic is my piston head at 1,300 miles.
Second is PencilGeek's at 20,000 miles...
How do you think mine will look at 20,000 miles?!

Gearhead999s · 08-09-2010, 11:56 AM

Here are some pics from one with 6500kms that had a spring break.

Carbon Build up

They replaced all 32 valve springs and it did not bend the valve.To best of my knowlege that car has about 40 kms on it with no issues.

ImStig · 08-09-2010, 09:34 PM

SuitedPair - Sorry to hear of your issues - it's such a heartbreak. Hope you will get a new car through the lemon law.

On the sidenote - is the amount of carbon buildup normal in the engine? Are there ways to prevent/eliminate/clean these buildups? Is quality of gas a factor?

SuitedPair · 08-10-2010, 10:46 AM

confirmed with SA it was the valve spring in cylinder #4.
SA said the buildup and burnt look of the piston heads is normal. (Now I know what BMW customer relations is going to say when I call them back in a minute...)

SuitedPair · 08-11-2010, 01:40 PM

Once the valve is replaced I have to follow the initial break-in period rules again, right?

SSH_12 · 08-12-2010, 09:30 PM

No, I would just take a easy on the engine for the first few hundred miles to allow the valve to get seated. Other than that, you should be good to go. I'm glad they didn't replace the engine. That would be a waste of a good M engine. That is also why you have a warranty for these things. At least you didn't have to pay the thousands of dollars for the repair.

That was nice that you didn't move his stuff around and the carbon on the pistons is normal. That is what happens when you burn fuel in a enclosed combustion chamber at high temperatures.

I'm sorry but we haven't been properly introduced... these are your first 2 posts...location is Florida... Which tech at Coggin BMW are you? Dan, Chris, James, or the engineer assigned to my case?

"That is why you have a warranty for these things" Really? Really! WTF!
THAT IS WHY THERE ARE LEMON LAWS FOR THESE THINGS!!!!!!!!!
That is exactly word for word the SH!T Dan fed me at Coggin. You also left out the other line, "we treat this issue the same as if a piece of trim fell off."
Unbelieveable!

Shame on you for saying this.

You really think provoking me is the right thing to do?

I guess my question then is this: What's stopping him from creating another account and posting from there?
