[Vwdiesel] 1.9 hybrid motor mistory

[82 Diesel Westy]

Hi all, you have all heard me chime in from time to
time with my motor issues.  You have all been a great
help over the years.

Now I have a big mystery.
My Westy died out in Penn State last October.
The motor had about 15K on it and seemed to be running
fine.

1.9NA block, 1.6NA hydraulic head, Overland long block
motor build using all 1.6NA swapped external parts and
pump.
>From what I gather over the months I felt the motor
timing was advanced to much and I blew #1 piston.
Here is what I found when I finally removed the head
yesterday.
#1 intake valve was driven up and shattered lifter and
blew off spring keeper.
The piston is fine, the valve does not appear to be
bent, just free moving in valve guide.
#3 intake valve was driven up and cracked lifter.

There are marks on top of #1, #3 and #4 pistons where
intake valve is kissing, but no dents or nasties.
#2 has a ccarbonring build-up when intake valve comes
close to piston top.
IS THIS NORMAL ON A DIESEL?




The motor had 2 head ggaskets a stock 1.9 and a
thinner metal one to match holes.
WAS THIS DONE BY OVERLAND TO POSSIBLE CREATE THE
CLEARANCE NEEDED BECAUSE OF THE 1.9 - 1.6 MISMATCH?


This motor ran on 3 cylinders after initial damage. 
At first it felt like I blew a fuel line to a
ccylinderuntil I heard the noise.  I was able to start
and run on 3 cylinders, the VW dealer that I towed it
to started it up and drove it into the shop!  It
sounded bad but ran on 3 cylinders with a cracked #3
intake lifter.

SO, DOES THIS RULE OUT A TIMING CHANGE OR BELT SLIP?
Belt seemed fine, tension good.

WHAT COULD HAVE CAUSED THE CONTACT?

This motor has had a noise for the past 8K or so that
seemed like a bad wwater pumpbearing, but swapping
wwater pumpdid not get rid of noise.
WOULD YOU THEN CHECK FOR MAIN BEARING ISSUE WITH #1
AND #3?


ANY HELP IS GOOD HELP?
I will take some pics as well and post.
I am thinking it might be better to start over with a
real AAZ 1.9TD long block and get the intake manifold
converter for my 1.6 stuff.
Thanks again as always.
