M52 - I think I'm having vanos issues

[ascendotuum]

How? Plate bolted down method?

OP: Rent the tools, get the rebuild kit, watch some great youtube videos, don't get high, stay organized and dive right in.. no biggie

That was exactly my thought process :up:

Where at in MD ? I've got the cam lock tools water pump wrench and fly wheel lock pin!! 12 pack to let you use it! I'm in Fairfax

That would be amazing will send a PM

Oh by the way take out the solenoid and clean the piston it could be getting stuck also.... my e36 M3 was doing the same and it helped but I got a rebuilt kit from Dr vanos just because I could hear that it was starting to rattle.

Will do

good for you!



It helps to have the cam timing tools but I've done it numerous times without them.

So before I left work today I unplugged the vanos solenoid. As I suspected, the hesitation and idle issues disappeared. Halfway home I plugged it back in and the hesitation started again.

I still want to verify that I don't have any vacuum leaks but I don't know exactly where to start, so I will have my mechanic friend help me with that.

But it sounds like I need the beisian kit.

Ahhh, VANOs sucks. Easiest way to check for vacuum leaks is to use carb cleaner, there are a few good videos on Youtube to guide you through it.

+2 on a vacuum leak.

Occam's razor my friend, start with the most likely issues and work up from there. Vacuum leak is the most common cause for drive ability issues.

I'm just going to ignore the condescending tone here.

good for you!

Unplug it and drive around like others have said. If you do need to rebuild the VANOS, beisian is the way to go. Excellent tutorials on his webpage and the prices can't be beat. I've used them.

I'm just going to ignore the condescending tone here. I just wanted to make sure.

Thanks for your help guys.

Thanks. And to test the vanos I just unplug the solenoid correct?

Thanks

using simple logic this would make perfect sense.........and was already suggested to you above.


If you don't really know how the vanos works or how its activated; its doubtful you can diagnose it correctly.

Rebuilding the vanos yourself using the Biesan kit is about 25% the cost of the Dr. Vanos unit.

I will try that. But how would I go about tracking down a vacuum leak?

Smoke test/machine is your best bet :up:

Sounds like a vacuum leak. You can see if the vanos is causing weird issues by unplugging it and driving to see
