Eagle's wifey's new ride

[willizm]

[MENTION=340]Eagle[/MENTION], I did my walnut blasting using the compressor and shop vac I already had. I picked up some tools from this place. Buy Blasting Tools

I also grabbed a media blaster and walnut shells from Harbor Freight. All together it was a rather cheap job. Also pick up some o rings for the throttle body and intake ports. Cheap insurance although some guys have been fine reusing their old o rings.

walnut blasting? blasting walnut shells from a media blaster? GTFO

 

[RICH17]

What are we walnut blasting?

Why does walnut blasting sound dirty? It sounds like an urban dictionary for

YALL ARE DIRTY!

Maybe I'm using the wrong terminology, but using this little plastic turd bucket with my compressor. Worked like a champ for dirt cheap

Portable Abrasive Blaster Kit

Came out pretty good

 

[Eagle]

Will - that doesn't even look that bad. How much improvement did it make in the performance of the car once completed?

 

[SleeperLS]

After you buy most cars... Change the oil. Buy a BMW...remove cylinder heads and blast it with walnuts. Don't forget to lubricate all o-rings with baby seal tears.

 

[Eagle]

Oh no, you have to change the oil too. With some fancy synthetic German oil. The stuff about baby seal tears is also accurate.

Walnut blasting the intake ports of the cyl head:

That looks terrible. Wonder if a couple of gallons of e85 will clean it up a decent amount.

 

[Eagle]

Car doesn't run on E85 without a tune and a perfect high pressure pump.

I guess the valve cover has some sorts of rubber baffles built into it which allow oil to enter the intake and the engines... I guess by design? ... consume some amount of oil on the regular. This is basically a maintenance item.

it's direct injection. fuel never hits the back of the valves. all the pcv wonderfulness cooks onto the back of the valves and fuel treatment won't take care of it. It's an issue in direct injection motors in general.

 

[OffshoreDrilling]

I need to pull mine apart and see how bad it is. got a quote for $275 locally

 

[Euro]

Because BMW

LOL! Let me know where that is... my quote was much higher than that...

 

[OffshoreDrilling]

$280

BMW Service, Performance and Beyond!


Found them randomly when I was still living in Carol stream

 

[RICH17]

Hmm I didn't know these older motors were direct injection. Makes sense tho. I bet they have a crazy PCV system as well.

This is the main reason I didn't get a ecoboost truck. The valves and heads ended up getting coated in carbon and crap, thus would end up needing the same service as what Eagle has to do. Sucks you have to do this [MENTION=340]Eagle[/MENTION], but I know it won't be an issue with your mechanical skills.

The car idles smoother and part throttle diravability is much better. It happens with all direct injection cars so every 50k miles is do it.

 

[OffshoreDrilling]

buddy works for Lexus and says they deal with it too. They pull the heads off the motor when they do it though.

it's a BMW bruh. They're always going to have newer better technology than economy brand cars.

im prettty sure [MENTION=56]Diavolo[/MENTION] just had that done...

maybe he can chime in

 

[Diavolo]

Here are my valves before and after getting them blasted. N54 had 38,000 miles on it.

 

[Diavolo]

That was stock too. I now have the MHD tune that you have, plus intake and dp
