Scott, It sounds so easy to check out the block. Honestly I did not
do it to my 83.5 because I thought it belongs to engine specialists.
On the other hand, replacing liners and heads are more common by
home mechanics like myself. My 83.5 was at 113k miles when I did that.
So I gambled it and assumed everything of the block was good. So far,
it runs better than ever. Its idle is so cool that sometimes I have
to step on the pedal to check if the engine is still running. I know
it's silly. The instrument lights tell me it is running. But sometimes
waiting for green light during traffic sitting behind the steering
wheel I can not hear nor feel my engine.
Why do you say Cofap a bargain brand? Is there any other brand available?
I was told that even VW brand liners are manufactured by Cofap these days.
I have not seen any other brands available other than OEM and Cofap.
