I recenly put an f-max kit on my 99 gsr and was running fine for about a week till a few days ago.

I raced my friend i noticed smoke coming from the breather filter off of the valve cover afterwards. I thought it may have been the head gasket because i noticed some condenstion on the oil cap and the car would sputter when I would take off.

Today I changed the head gasket and i couldn't see any damage to the gasket but it was covered in oil/coolant. Got the new one in and it idles better than it was right before we changed it and doesnt sputter any more but there is still smoke or steam coming out of the breather filter on the valve cover. It doesn't smell or feel like oil which makes me think that it's coolant, but I dont know why or how it would come from there. It is also smoking a bit from the exhaust but not a whole lot. I'm lost and just want to get my car running right. Any help would be greatly appreciated!

 

usually that means that ur rings are gone

 

Ok, I am going to do a compression test on it as soon as I can If its not that what other things could it be?

 

How does that let coolant through?

 

Not to be on the negative side, but the last time i saw smoke coming out of a breather filter they blew their motor. So be on the lookout and get it checked out.

Please keep us posted!!!

 

definitely sounds like the rings.

 

i have never seen this in person

but nearly every time someone posts about smoke coming out of valve cover, its rings unfortunately.

 

Can you install pistons without machining?

 

I have seen this in person, and it is the rings, lands, or pistons. A comp test will usually tell the tale.

There is usually some smoke/steam that comes out the tailpipe as well. Especially if its bad.

The smoke is not coolant, it is exhaust steam (blowby). Don't drive it long like that, it essentially steam cleans the inside of the crankcase and removes oil while leaving behind corrosive junk. Not good.

Last time i saw smoke out of my breather was when I cracked a sleeve. It was steamy. And motor would not idle.

 

up

 

cracked sleeve maybe?

but it it's just oily smoke coming out the breather, it's probably blown rings. happened to me. it's stinky.

 

I'll put my money on a cracked or blown ringland...compression test will tell all

 

if a compression test gives you good numbers, do a cylinder leak down test... they are far more accurate.

 

... i did a compression test... numbers were 180,178,185,185... and i am still burning oil... so i would have to agree...
