VRSF charge pipe N55 bolt size

I noticed a small oil residuals coming from one of the bolts that hold the Tmap sensor into the charge pipe. I'm thinking of changing the bolts maybe that would solve the oil leak.

What is the bolt size?

Uhh there should be no oil coming out of there that is the tmap sensor only air should be flowing through there.

I agree and this is something i find really strange. What i really meant was oil residuals. The same way that you might get a bit of oil on the tmap sensor. I was told this is normal

To make things even more complicated, when i unscrewed the other bolt, it was clean , no oil nothing. Even the sensor it self is clean. So why am I getting a bit of oil on that specific bolt only?

It can vary from CP to CP. If your screws hold but are just leaking air/oil, i would just use a small amount of thread sealant on them. Also check for excessive blowby if you have oil there in the first place

I think I might have excessive blowby, what I did was get another M4 screw with a longer length. but for the blowby I am getting a catch can, and I am referring to a n20 chargepipe from vrsf so the bolts are the same size as the n55 one
