The previous owner said he seafoamed the car and ever since the engine have been blowing out white smoke near the header this only happens when the car warms up. My buddy told me I had a valve stem leak.

 

valve stems are easy to replace, are you loosing oil ?(burning it)

 

I'm a quart low. And I think I am

 

Where exactly near the header?
Is the head missing a header bolt/nut

 

Well I just took off the shield for he headers and I see alot of oil on it on the left side of the headers

 

So you see smoke burning off the headers? Not around them?

 

No. It's just the left side of it that's smoking

 

The header. I couldn't see what the problem wa earlier because I didn't take off the header shield. When I ha the shield on the smoke was coming from the left side of it

 

im betting the valve seals are leaking after the sea foam application

 

Only this much sea foam will cause engine damage.

 

oil on the header? sounds like you need a new exhaust gasket or valve cover gasket.

Ill save up for new gaskets. See where that gets me

 

I have a 1990 240sx KAE and i seafoamed it by putting it in to the gastank and used recommended amount. I now have white smoke, but it lasts for a while after startup. How long is the smoke supposed to be there. I just wana make sure its not something other than just the seafoam.
