[Healeys] Glycol in oil

[Wayne Schultz]

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.

               Wayne
