If I take off my Valve Cover, which is no longer leaking, to replace my VANOS seals do I need to add more RTV or anything? Can I just take off the Valve Cover, do the seals diy, and put the cover back on without expecting any leaks to occur? I hope I don't need to replace the VCG every time the Valve cover comes off.
Already did VCG, want to do VANOS seals.

How old is the VCG? If it's newish, you can just clean it up and add RTV.
Literally just changed it like 1,000 miles agoHow old is the VCG? If it's newish, you can just clean it up and add RTV.
You'll be fine as long as you clean it up. But I would add RTV to the appropriate spots (half moon and VANOS seams).
Just to be clear, I already added the RTV when I just replaced the gasket. Should I add more?You'll be fine as long as you clean it up. But I would add RTV to the appropriate spots (half moon and VANOS seams).
Yeah, you should. It will be dried up and won't retain its sealing properties. You will have to peel/scrape off the old RTV from the gasket and the head. Make sure the head is spotless!

No need to be a d!ck with the thinking logically comment. Didn't know the RTV would simply peel off or have lost it's sealing properties in 1,000 miles. Thank you everybody for the quick repliesClean old rtv... Apply new.. Think logically

he's not being a dick, just telling you to use your head. The rtv set and when you pull it apart it will not have cohesion at both ends.
Exactly what I thought as soon as I read his reply.he's not being a dick, just telling you to use your head. The rtv set and when you pull it apart it will not have cohesion at both ends.
My apologies, inappropriate. Just thought RTV was meant to act like a gum, not be cohesive. So once it was there, it would stay "gummy" and make a seal during later projects. Glad I checked, and sorry again.Exactly what I thought as soon as I read his reply.
Nah, don't be sorry. There are more tactful ways to say it.
That's how I felt about it, but my reply wasn't any better.Nah, don't be sorry. There are more tactful ways to say it.
I would not risk the possibility of future leaks. Redo with brand new VCG and rtv sealant. Its not expensive

Let's not get too polite here on this board or I'll wake up wondering where I am!That's how I felt about it, but my reply wasn't any better.
A little bit of wise guy with solid tech advice is why I come here.
All in fun! Skin too thin not allowed.
RTV will harden. So it will tear when you disassemble. New will seal properly.
Probably can clean the VCG enough to work OK.

Not sure. Wanna check for me?Translation: you need to be circumcised.
1,000 miles is nothing, you can re use it!
just pull it out,
clean the cover and gasket. Wipe it clean.
then after the vanos are done,
return it as if you were putting on a new one.
no biggie
im being sincere here so please dont call me a d1ck lol

Reuse it, as long as it still feels like rubber.
I did my vanos seals after 1 year of doing vcg. Still feels soft.
Do buy some RTV sealant.
It's $5 in any auto part shop. It's really soft red substance, so it won't really deform the VCG after you tighten the screws. The extra orange sealant just get all pushed out of the edges. Might not be pleasant for the aesthetics of the engine bay but who cares, as long it keeps the oil in.

Make sure the sealant you are using is O2 states that it is O2 sensor safe. It will say so on the package. Some of them are not. Also, some will debate about how much of it would take to damage a sensor, but why take a chance? See paragraph 3 in the link below. There is also a post on the Forum about it, and you can check Bosch's website. I thought it was BS when I heard it, but it seems to be true.
