[Vwdiesel] *93 EV DSL - cyl head work - pics - PLS ADVISE*

[Shalyn Shourds]

Well, when I blew the belt tensioner on my TDI head and exploded a 
couple of lifters, the shop that had not too long before installed that 
tensioner sort of honed out the shredded lifter bore and told me that 
the head was fine.  When I took it to a good rebuilder in town that had 
experience in aluminum heads, they told me that it was a few hundred 
dollars from good.  There were still divots missing.  If the surface 
isn't cylindrical, it may not hold oil pressure.  The rebuilder welded 
up the area and re-bored it so that it was back to cylindrical.  Also 
had to mill out the adjacent bores because they were deformed from the 
trauma too.  That head worked fine until the belt blew again thirty 
miles later.....

Doesn't seem like 0.003" is a lot.  I don't know what reference it is 
for you, but the max warp for a 1.6 head is 0.004".  Shop took one pass 
with the surfacer on my TDI head just to check to see if it was level or 
not.  I've heard mentioned on the list of people surfacing until they 
hit valves.  Looks like you're not supposed to switch cam blocks, but 
the camshaft just torques on.  No plastigauge or anything.  I hope cam 
block order doesn't matter on the TDI because I got a cardboard box of 
parts back from the rebuilder....  Fellow intrepid list members have 
rebuilt heads at home with good results. 

Whether you want your camshaft back may depend on if it came out of the 
trauma with all of the lobes intact.  Sounds like to me that this guy 
and you have about the same head rebuilding experience:  only difference 
is that he's done more Chevy 350's.  I had to look all over town to find 
a shop willing to touch the head on my TDI.  Most of them said "No" over 
the phone.  One or two said "Yes" but shouldn't have.  As to what he 
deserves, well, I think we all know the answer to that.  What it will 
take to make the situation work out in your favour I don't know.  I wish 
you were around here so I could at least point you to a decent 
rebuilder.  Part of the beauty and the tragedy of this being an 
international list. 

I am so sorry that this is messing up your day.  It is a tragedy, though 
one well told and illustrated.   Also, one that can still end up 
satisfactorily. 

Keep the faith!
