The problem with the V-6 headgasket issue is that damage to the block and cylinder can and does occure without the owner even knowing about it as the leak is usually internal and slow. That's why Toyota had to replace so many motors. So, as if replacing the headgaskets wasn't enough of a pain, now you have to worry if the block was scorched as well.


This same scorching is common with 22Rs. It's way too common for these little engines to also get serious erosion of the water passages.

Don't get me wrong, the 22R is a great engine. But, it has the same basic flaws and strengths as the 3VZE.
