crap in cylinder head
I recently bought a sr20de from the salvage yard and I'm starting to tear it down and clean it. I took the valve cover off and it's black with baked on oil and other crap and under the valve cover is dirty too. What's the best way to clean this my self to avoid taking it to the shop for cleaning? I've heard oven cleaner works but looking forward to responces from people who have had this problem.
