I have the stock valve covers and they are leaking around the oil cap and pcv valve oil all over the cover. Also oil is going from the breather tube that runs from the throttle body to the valve cover. I have oil coating the whole inside of the intake. Do I need to get valve covers with baffles?
Thanks, Gary

The stock covers DO have baffles...sounds like you have excessive blowby to me. How many miles on the engine? Check the PCV valve as well, but with oil in the intake it probably works.

It has 150,000 miles. So what does the blow by mean?
Thanks

 

Either your rings or valve guides are excessively worn allowing combustion gases to create excess crankcase pressures. Does the car use much oil? I would do a compression check on it and then repost the #s for us so we can help decide what it is. The 350 might be due a rebuild, although from your sig. it runs well. Hope this helps.
