Hey there!!
Quick question, i have a 12A and the exhaust manifold is removed. Is it safe to pressure wash the engine with just rags stuck in the exhaust ports? Im wanting to paint the engine and need to clean first. Thanks!!! Shawn

 

You would probably be ok with rags in the ports, as long as you don't direct spray right at them. But I would feel better about making a blockoff plate and mounting that instead.

Just my $0.02.
