When I threw my original block away in the early 80s it was when I took the pan off the water was dipping from above the cam. I don't think I thought about removing the tappet cover. The replacement block was free!Ken Freese 65bj8Sent from my Verizon, Samsung Galaxy smartphone

It is block cast iron porosity. It oozes very slowly from an area of about 1.5 x 1 in.Access is limited too. Just hoping that there are no other porous areas.A proper fix to my mind would be engine out; block stripped and vacuum resin impregnation - probably not going to happen for nowWhat intrigues me is that this is in exactly the same location as Wayne's friend had. So it surely is a weakness of this block ?Wonder how many others there are out there - some maybe unknown too ?I only picked it up by noting the creamy damp gunge in the inside of the valve cover. Remember too that less than a teaspoon of glycol in the oil triggers the oil analysis alarm.rgrgVirus-free.www.avg.comOn Sat, Mar 16, 2024 at 7:54 AM Michael Salter <michaelsalter at gmail.com> wrote:I am definitely not an expert however I have successfully repaired some irreplaceable cast Iron water pump impellers using this product.https://www.silfos.com/EN/Products/EASY-FLO-45.htmI opted to use this because a very much lower temperature is required.MOn Sat, Mar 16, 2024 at 10:12 AM Bob Spidell <bspidell at comcast.net> wrote:

  
    
  
  
    MIG/TIG isn't usually effective on cast iron. Brazing might be your
    best bet, and plenty strong. I brazed a mis-sized plug on a
    so-called 'uprated' water pump for my BN2 that wouldn't otherwise
    seal up and the result was good, but I feared I'd damaged the seal.
    Clean best you can and use a good flux.

        Congratulations on finding
          the leak. I would not have much confidence in any epoxy. The
          area would need to be impeccably clean including inside the
          actual crack & the block gets very hot. I wonder if it
          might be a candidate for an expert MIG/TIG welder?

                        Wayne - you are a star !
                        I got lucky and think that I have found it.
                        Started by removing the center tappet side
                          cover.
                        Just like your experience - mine is below
                          the center cover mounting boss; there is a
                          ridge there just above the distributor drive.
                        Was this where the one you worked on was ?
                        
                        Actually looks someone tried to repair it
                          before. Have no idea what they used, but is a
                          soft white putty like substance and the oozing
                          got worse when I removed it. Had the coolant
                          under pressure.
                        So now have to clean up and think about a
                          repair technique.
                        Thank you for responding .

                              Wayne,
                              Thank you. That sounds very similar
                                to my situation. Not quite sure that I
                                understand what you mean by the boss
                                that goes down to the sump ? Is this the
                                oil return path - interesting. Yes, my
                                plan is to get the pan off and
                                pressurize the coolant with some dye in
                                it and hopefully locate it. 
                              So your repair was done with the
                                tappet side covers off ? Maybe that is a
                                block weakness and I get lucky with a
                                similar fault.

                                Hi Roger,
                                  My friend who had a  Healey 3000
                                    had  a similar issue. We would
                                    find coolant in the oil on the
                                    dipstick and filler cap. I found
                                    when we pressurized the cooling
                                    system with the engine warm, no leak
                                    noted, with the engine cold a slight
                                    coolant leak in pressure. I decided
                                    to drop the oil pan to look for
                                    leaks and found a very slight leak
                                    internally dripping into the oil pan
                                    area. We found that the leak was
                                    from the boss in between the 6 and 7
                                    tappets.  With that  tappet cover
                                    off we could see coolant drips
                                    forming in that boss running down
                                    into the pan area. It would only
                                    leak when cold. Porosity? I think
                                    so. I decided to Peen  the boss with
                                    a punch and seal with JB Weld. It
                                    has been good ever since. I suggest
                                    dropping your oil pan to look for
                                    leaks might be the least invasive
                                    first step in locating your
                                    problem.    Good luck.
