Max, what you said is very true. That's why a $150 pair of good used
heads were suggested. If the used heads do their jobs well then it
will proven worth a set of $200 liners too. My 83.5 suffered the early
Vanagon head gasket leak syndrome. I had VW worked on it under some
warranty coverage. But they put on a set of new heads and did nothing
to the liners. The 1.9 engine had never had all the horse power it should
have. So eventually I did the work to put on a $200 set of Cofap. After
3000 miles of break-in now the 83.5 Westy has all the horses it should have.
It's a huge difference before and after. The condition of the liners
plays a critical role if the engine is going to perform or not.
I guess the bottom block needs to be in good shape for all these to be
invested. The mileage of the engine is a good check point. If it is high
there is a good chance the block needs to be worked on first. I think
it has been said before that 1.9 WBX block is likely to be OK if the mileage
isn't too high.
