[Vwdiesel] pulling pistons for bearings and rings

[mikitka]

You can pull the pistons out from the top no problem.  I did to re-ring my
1.6l TD 91 jetta. I did it in the car as well.  There are several that have
done it and even rehoned it while in the car. You just have to clean up the
cylinders really well when you are done. Some have used Total Seal rings, I
just went back with standard rings from Hastings.

I would replace the bearings as well. Not hard and since you are that far
may as well.

The old pickup 1.6NA is torn apart on the stand.  It was burning a ton
of oil, smoking and starting to run away.  I was expecting to do a full
rebuild.

(Engine was running when pulled)

The valves in the head are very loose, and the exhaust ones are quite
worn.

As for the block, there's just a little carbon at the ridge - I can
catch my fingernail on it - but not much else.  I can still see hatching
in the cylinder.

The block has an official VW reman sticker on it, makes me wonder what
size bearings and pistons I've got.

I pulled #3 main, and the green plastigauge says it's within specs for
NEW bearings.  I pulled the #1 rod bearing and the green plastigauge
says it too is within specs for NEW bearings!

I suppose I should pull all the caps and plastigauge them, but...

At least I'd like to throw on new rings while I've got it apart.

According to the book I've got to pull the crank to get the pistons out.
(and according to my mechanic buddy, I should pull it before honing the
cylinder wall anyway)

Or is there a way to pull the pistons out the top and run a quick hone
in the cylinder?

This is my first try getting into the engine guts.

Thanks,

Will.
