[Healeys] Glycol in oil

[warthodson at aol.com]

 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?Gary Hodson

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 .rg

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.rg

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.
