$30 insurance for your VANOS unit.

"TONESTER" VANOS Maintenance :thumbsup2:


I was thinking since I've replaced all my big ticket items on the high failure rate list... I decided to do a little preventative maintenance to my VANOS unit w/ my recent Inspection 1.

Since VANOS unit are very sensitive to shavings/debris since inside there are a couple solenoids and seals that move at a very high rate of speed to induce oil pressure to advance/retard the cams... any sort debris would cause damage to those seals and/or score a solenoid causing premature failure.


I took off the "#2 - Solenoid Valve unit" since I noticed the "#7 - Sealing Plate" was seeping a little bit of oil.

I also ordered all the O-rings on the "#3 Pressure Limiting Valve".. I also went ahead and ordered the "#4 - Filter Cartridge" for the Valve. I figure.. its a filter it should also be replaced or at least cleaned out every so often.

When I removed the Pressure Valve... just as I thought, I found quite a bit of metal shavings and debris in the filter, probably from the break-in and debris just built up over time.

Cleaned everything up, put it all back in... it didn't make the car run any better (nothing I can feel).... but I do sleep better at night. :laughhard:

I would recommend anyone/everyone to get theirs replaced and or do it your self, if you think you can tackle the job.. its pretty simple and extra insurance for about $30.

I didn't have my camera with me to take pics of the nasty filter on the limiting valve.. hopefully someone who does theirs in the near future can snap a photo of their filter.

+1 - hard to follow just by reading - kudos though for doing that and for the heads up.

NO special tools needed.

If you feel that your "Sealing Plate" is ok and is not seeping, and you want to JUST change the O-rings/filter cartride on the Pressure valve... All you need is a 22mm wrench.

Remove the Pressure valve (22mm), remove and replace O-rings, remove and replace filter cartridge.
