That is the general location of the leak shown in the photos I posted.
It's hard to see with everything in the way. Try taking a photo with a camera (does
anyone have those anymore?), or your phone ie: hold it down more at eye level
to that area and take a few shots. The leak comes from a vertical slot about
an inch long which is where the timing chain cover mates to the block
in a 90' rounded corner ie: the timing cover edge comes down vertically
then changes direction to horizontal just behind the pump cover (see the
photos in the thread).
The slot is where the leak comes from, then it trickles down into another horizontal
slot, then dribbles forward over the oil pump cover area.
I cleaned the entire area off on one of my 80;s by hand, a real pain because like
your engine, everything was still attacked, scraped the heck out of my arm trying
to get down in there, but after an hour of cleaning and fiddling I was able to
get some FIPG into that area and the leak stopped.
The 80 I'm working on now is half apart (fan shround, pulleys, water pump,
belts, alternator, battery, etc all pulled out), so it was super easy to clean
that area, dig out the grime and push some FIPG into those slots.
Tell me how you attached the photo and I'll try to attach one, or could
add it to the thread.
One tip, I never use Carb or Brake cleaner near O-ring or rubber seals; the Acetone
can/will damage them. So I use mostly non-solvent based cleaners for removing grime,
ie: CRC Degreaser (Wallymarts) or WD40 Industrial strength degreaser from ?home depot or lowes (they say it doesn't harm rubber, plastic, or paint) then for the final cleaning so the sealant/FIPG will stick I may use some CRC Electronics cleaner, it's formulated to not damage rubber seals. Only drawback is it's more expensive that Carb/Brake cleaner. Then wait 10 minutes for it to completely dry up (what's sitting in the hole) and apply the FIPG/sealant.
Main point; better not to use Carb or Brake cleaner as it may further damage the seal
if it gets down into that slot, theoretically.
I am having a hard time visualizing where the slot is. Can I just put a dollop of RTV black on my finger and just rub it around everywhere in that area?
