I have had a small constant oil leak from front of engine on a 1992 accord for years. Today there is a major leak in the same place. Is it the front crank seal, front cam seal, or one of the balance shafts seals ? How does one know which seal to repair ? Any repair tips would be helpful . Thanks Ron

 

Do all the front seals next time you do your timing & balancer belts.

 

if it's a major leak it should be plainly evident once you remove the side engine covers and look.

do you know if you have a retainer on the front balance shaft seal? if not that seal could have come out and when it does the engine loses oil FAST.

replace all the seal, they are cheap. I use a scratch awl and poke it through the face of the seal and pry it out, then I use a large socket to tap the new seal into place.
