My second attempt to respond... Sigh
I agree 100%, make sure that you purchase a engine brush kit to clean out the oil passages. Worth every penny spent! Run the brush through the crankshaft oil holes also.
I use a bucket with Dawn, hot water, and a couple of Tide pods tossed in it. After I scrub everything, I use a power washer to blast through every orifice, nook, and cranny... Make sure that the water streams out the opposite ends of the oil galleys. If it doesn't stream out, investigate as to why...
