Hello everyone, I had someone (acura tech side job) replace my front and rear valve gaskets last week and now I just noticed this leak. Can someone tell me what kind of leak it is? Thanks!

 

did you do the spark plug gaskets as well? looks like oil to me maybe he didn't clean it before re-installation. Is it fresh?

 

didn't notice it when I picked up the car last week. yesterday is when I looked under the hood and noticed it. it is fresh oil. maybe I will have to check the spark plug. thanks!

 

He shouldn't have touched the plugs for this job, but a plug could still be loose.

I'd wipe it clean and monitor it for a few days.

 

you would assume so since he is an Acura tech, but i'll check the plug later today if I can. thanks for the advice.

 

Could it also be the gasket for the spark plug tube? I know those gaskets can get torn up when removing and installing the valve cover. Or would that just cause oil to get into the spark plug tube and not leak outside of the valve cover?

 

So i checked the coil and it's dry. Upon closer inspection, the leak is coming from the black thingy (with the single bolt) underneath the dipstick. Is it as easy as it looks as to removing that bolt and replacing the seal? Thanks!

 

I was going to say it looks like the pcv valve is leaking. There is an o-ring that may be seeping. I'd get a new pcv and try that

 

it's definitely leaking from the pcv valve assembly. so, is it as easy as I looks to replace it, just the one bolt? Should I replace the whole assembly or just the O-rings? thanks!
