I have a 2005 Acura MDX with 183000 miles. It's blowing white smoke out the exhaust. I have pulled the head to get them cleaned and pressure checked. There was a lot of sludge in the valve area. The gaskets all looked good, no crack on the block. Thinking 2 cracked heads. I was contemplating swapping motors. I have a 2005 Honda Pilot with 150000 miles. Can you do this between the two makes. Any help is appreciated.
