Denis, i understand but what is the point? you have a problem anyway! it
need to be open, there is no way out, wile there, it's nothing to take a
look at the pistons or/and head. The only thing good about a leak down
it to tell the customer (or friend) the approximated price of parts,
even then, if it show a leak on the pistons side it doesn't tell you
that the heads are worned out or close to it! the thing that people
don't understand is a leak down will tell you that your +- 400$ on a 3
to 5 k job. The time to go there and open everything is practically the
same. I don't even do compression check anymore, i look at the engine,
drive the van, touch the engine for vibration and i know. What i'm
trying to say is that with a leak down, you can only tell that the price
may be bit higher.... or lower!
Cheers, Ben
