Roush 427R Oil Around Spark Plugs

[REY 427]

My Roush 427R has a little over 3,600 miles and recently I found a small oil drip under the car. The small drip has gotten a little bigger after the last two times I've driven it. Looks like the oil is coming from the passenger side spark plug holes. I removed one the of the spark plugs and the porcelain was pretty soaked in oil. No oil was on the electrode. Any advice on what I need to do? Is this a simple gasket replacement or am I looking into a potentially bigger problem? Any help is appreciated.

If there is no evidence of oil on the electrode or in the side pipe, and only on the porcelain, then my first guess would be a valve cover gasket leak. Check the bolts that hold the valve cover on to make sure that they are tight. If they are tight, remove the valve cover and take a look at the gasket. If the gasket is overly compacted or torn, replace it. The valve covers need to be snug, not overly tightened. Sometimes people tighten them too much and it destroys the gasket.

Hopefully that's the case. Any idea on the part number of the valve cover gaskets? Just want to have that just in case it's the problem.

Just snug up the valve cover bolts.
Do not tighten them, just snug them up.
It most likely has reusable gaskets so no need to replace them.

Mine came with cork gaskets which when saturated will continue to leak. change them out.

Where did you get your new gaskets from?
