Not bad but there are better videos

rotate engine clockwise also, you went backwards.

@bmw628csi Thanks for the feedback. I am pretty sure I was the first to make a video for the E46 M3 valve adjustment. Next time, you can make your own video.

Thanks for the video. It looked like you were having a tough time turning the engine over. Not sure if your spark plugs were removed or not, but that would make it easier.

[cncmastr]

@nsrimmer84 Yes, spark plugs were removed. I did the VA because I was doing a complete Inspection II, which does call for replacing spark plugs.

Great Vid. I'll add to favorites incase I get an e46m3 someday.

Question: What mileage interval do you do this adjustment?

[cncmastr]

@ashperkins Google search this term: "Service_Checklist_2004_US.pdf­"

Also search these items for a more comprehensive list: "mike miller old school maintenance schedule"

[cncmastr]

@ashperkins Different schools of thought, Mike Miller says every 60K for the S54 engine. Inspection II from BMW says every 30k.

@lackodeniro Im also confused by this, I assume he said this backwards.

[lackodeniro]

you said "find a smaller shim " doesnt that increasing the gap?  you wanna make the gap smaller why you go with smaller shim? You wanna go upwords!?

I have an E46 330i and the only performance item I have is the Signature Motoring performance CAI for about $160. The performance kit adds around 13.5HP on the dyno, sounds freaking great, and installs in under 30 minutes. Highly recommended.

-13.5 HP increase

-Lifetime filter

-SOUND AWESOME

-30 min. install time

Aside from the power gain, the SOUND is amazing at higher RPM but sounds normal in regular driving. I’m thinking about added high-flow exhaust next.

That is not right moving the crankshaft counter clock wise. The correct way is clock wise otherwise you put to much pressure on the valves.

I watched the first minute of this vid and couldn't take any more. You never "Never" turn a chain driven engine backwards! Sorry but major fail in my opinion.".

Could I ask where did you get the clearance numbers? Thanks.
