is it worth the time to polish rods and crank?
Posted 10 June 2004 - 07:05 PM
because there is so much oil around and about the crank and rods in a flat 4, I was thinking this would have some good benefits.
Also, what about the insides of the block, I've seen small discussions on polishing and/or painting (high temp engine paint) to reduce tendancy of the oil to stick to the insides of the block. I think this might not necessarily be worth the time.
Thanks for any opinions.

Polishing the case could cause some trouble (I know it can be disastrous for a air/oil cooled VW), as it will reduce heat transfer. Polished surfaces have much less surface area than the raw casting, the oil will hold more heat instead of passing it out through the case and to the water jacket. In fact, one of the important things that oil does is transferring heat from the friction producing areas to cooler places in the engine so if it spends a little clinging to the case its really not a bad thing, as long as its not so slow that you’re pumping the sump dry.
