the head gasket was a elring(sp?)
ive used them before..no problem..
i used the old non stretch bolts..
re-torque as per Bentley manual ..
cleaned bolt holes..
gasket on right side up..right new head gasket..
coolant is still great..
today i checked block for warpage
ran a smooth file over block surface...
there was disturbingly 'low spots' round all the holes.
i choose to ran the smooth file over the block surface
to get a better 'flat' surface :o/
i know ive done this before on other diesel vw blocks
before rebuild with no problems...don't think i did it to this one though.
(will check projection after..but don't think it should significantly alter it)
i am also going to get some stretch bolts..
but i have the 'smaller' bolts..can i get stretch bolts in the smaller size?
im told there the same as the gas ones...wondering if i should use gas ones or stick
with the non stretch small hole ones for diesels?
Also, what torque procedure did you use? You gave it a "warm-up" and "1000 mile"
torque? The bolt holes were very clean before installation? The head gasket is
right-side up? You began with a new gasket? The coolant is still good?
