valve adjustment

yvel26 · 01-15-2011, 02:28 PM

Hello,

I have heared about valve adjustment on a M just recently.
Never heared about it before.

When has it to be done?
And what are the costs?

Thanks for the info.

every 10k-15k miles ish should be sufficient. Around $500

whoa, this is new to me! (that its so often)

Caddyshk · 01-15-2011, 03:18 PM

It's more like 22-30K miles

Arxangel · 01-15-2011, 03:39 PM

Should this be done on the 3.0si as well?

Not according to BMW...

Interesting, only the Ms get to do it.

Different engine....

Caddyshk · 01-15-2011, 04:02 PM

Way different...

pokeybritches · 01-15-2011, 06:35 PM

3.0si has hydraulic lifters, just like 99% of the other cars on the road. There's no need for a valve adjustment. Valve adjustments are more of a "have to" than a "get to" with the M.

OP: There's a DIY out there to show you what's involved, but I wouldn't attempt it myself if I didn't know what I was doing. Do a search. Valve adjustments are supposed to be done every inspection (22-30k miles).

BS - I drive it like I stole it on the street, and do 4-6 HPDE's per year. Mine is winding 24,000 miles for Inspection 1 - Sorry Ocha... No early work for you...

O-Cha, are you seeing things enough out of spec at 10K-15K miles when tracked often or driven hard on S54s?

It's just the schedule I follow, and yes I see valves out of spec with that "few" miles" but I also only wait 5k max for oil changes when BMW tells you to go 15k.

YMMV

Cool. I'll see what things look like at Inspection II and adjust (no pun intended) from there.

Valves adjusted on my 2006 M Coupe with 20K at dealership. All valves required shims to bring into factory spec however, tech stated that the wear was within expected for mileage.

yvel26 · 01-16-2011, 02:45 AM

How do you notice when it has to be done?
Do you feel it when driving te car?

ycolton · 01-16-2011, 03:26 AM

I did notice a slight decrease in motor noise but no performance difference before and after adjustment. The necessary adjustment was within the range of normal engine wear.
