Another Vanos Oil Line Leak Or Something Else?

[SMGM3]

You will have your solenoid block out regardless to change the plate or the orings in current plate so I would take the time to clean it via the magnet method, might as well.
You do need some pretty strong magnets though, if you have an old HDD from a desktop PC at home you don't mind losing open it up and use the neodymium magnets found inside.

I like your thinking. Gotta be an old HDD around here for the task.

Wow, thanks. Its perfectly flattened without any bulges like might be present on a deformed part. I'll be sure to use the new one.

I'm installing a new vanos plate with the viton orings. Is there any reason to take off the solenoid for additional deep cleaning? Beisan DIY suggests doing so but not sure if that's overkill or worth the extra effort.

That black band used to be an o-ring when new. It's only flattened because it's old and heat cycled. Definite preference for the new part.

The Vanos Pressure Regulator came in from Dr.Vanos, on the right. Looks more like a traditional oring on the end, whereas the one from my vanos looks more like a black band. Should I have a preference for one or the other?

[SMGM3]

Dr.Vanos hooked me up with a used but very functional pressure limiting valve including new orings. Also picked up a new vanos sealing plate. Highly recommend him.

I would buy a new regulator and o-ring if it doesn't already come with one. The pressure gauge/fitting I bought of ebay from the UK took months to come. Contact Raj at Beisan, he sent me a gauge to help troubleshoot a vanos issue I had and told me he had planned on selling them soon, so maybe you could get one comming in days not months.
Good luck.

It comes with both orings and filter.

I'll check with him. Thanks for mentioning it. Appreciate your advice and pointing me in the right direction.

Not supposed to adjust that. The leak is probably coming from the VANOS sealing gasket as it looks like it is dripping down and to the back toward the chain tensioner. Also, your serpentine belt is cracking and probably needs to be replaced.

Thank you for mentioning that. Yes, belt has been replaced.

Definitely don't start your car now. That inner bolt is how the pressure is set for the VANOS. You'll have to unwind it back to roughly where it was before and then —with an appropriate VANOS pressure gauge— set the pressure to 115 bar. You could also just buy a new part, they come preset to the correct pressure.

You guys are awesome, thank you! Learned another lesson today.

I was a moron and just sheered the Vanos Pressure Valve/Regulator by tightening the inner bolt using an allen. 1. What the heck are the consequences? 2. Do I need to untighten the exact number of revolutions that I tightened? I was trying to ensure it wasn't leaking.

That's a coolant pipe. I suggest you remove the driver's side fan shroud and the VANOS solenoid. That will give you a lot more access to clean. Then with everything clean, diagnosis should be much easier.

The Beisan solenoid procedure has instructions on how to remove and reinstall: http://www.beisansystems.com/procedu..._procedure.htm

There's only five bolts that hold it on, but be ready for some oil to spill when you remove it.

That's exactly what that is. Total brain fart not to follow it to the expansion tank hose. Thanks for pointing me in the right direction.

Ok that is not the source of any oil leak. Still looking for the culprit.
