Subject: Re: coolant in oil
He he, you all know those are my favorite post/subject (and the cooling
one's), a year ago, i offered you a video (way before BB and Bostig did
theirs :-)))) and some pictures of the procedure, of how easy it was to
change this one wile there.

No, same for 90% of the van i do, BUTTTTT, i fully agree with you on
replacing those wile there. This is why when you push back the sleeve in,
MAKE SURE they are not comming out again wile doing another cylinder!!!
As you turn the engine toget others to TDC, HOLD the one trying to go up
firmly down!!!
The coolant system as pressure, the case/oil as none (if you have some you
have a big problem), so by gravity and by pressure, coolant as a tedency to
go in oil. BUT, let see where coolant can go in oil:
-from a badly seal head stud (the 4 in under the valve cover
-from a crack in the block
-MAYBE from a crack oil cooler
-from a cracked sleeve

and of course a lower o-ring
If the cooling system as NO pressure (an 50% or your vans dosn'T have
pressure mostly from a bad exp cap), now maybe oil can makeit into the coolant.
I the next month, i the same mood as BB & Bostig, i will do a video of the
full top end procedure. I little more condense then the BB & Bostig one...
probably more funny also... hey hey.
So Frank, you should come here so we would look a bit as funny as BB &
Jim... Nahhhh, we wouldargue too much OLD school guys!!!! baaaaaaahhhhhh....
Ok, shop is now up at a nice working temperature at 42F :-))))))))))) NOT

87 vanagon. I finished the head job and only ran the van for about 1 hour. I
then let the van sit for 3 weeks while i was on vacation. temps were well
below zero on some occasions while I was gone. Upon returning I looked for
noticeable head leaks and was to happy not to find any. I warmed up the van
a few times but did not drive it. Yesterday I checked the oil and there was
a lot of coolant in there. So I drained the oil. So all I can gather is 2
things. Oil cooler went south while I was away and upon returning and
warmung up the van it allowed coolant to get into the oil. There is no oil
in coolant BTW. The second thing is when I did the head job, the number 4
cylinder started to come out with the head< I was able to free it before it
got past the rings. The cylinder did get past the last ring But I was able
to slide it back into place. Could this be where the leak is? I am guessing
that I disturbed that oring that is located at bottom of cylinder jug
towards the block. I am hoping though that it is the oil cooler as that
would be the easier fix. Do oil cooler fail like that, and if so wouldn't
oil get in to the coolant and vice versa. To recap I only have coolant in
oil, not the other way around. Also would it be possible that coolant could
have got into the oil during the head gasket repair? pretty frustrated here.
what do do next?
This is probably a classic case of why it is necessary to change that 0-ring
on the bottom of the cylinders that everyone is always trying to avoid
doing. EVERYONE I've ever changed was as hard as rock and comes out in dust
format having to dig it out of its groove with a pick. Now with that bit of
knowledge what makes you think that once you remove the tension on the head
studs that the 0-ring will re-seal when your torque down the head ? I have
posed this message numerous time as have others, the archives is full of
this story and I have a section on my website about it >_VW Vanagon
