[Healeys] 6-cylinder Rear Crankshaft Oil Seal Conversion Kit

Fri Mar 26 16:40:25 MDT 2021

Is it possible that is the flex line going to the oil pressure gauge that
has failed and it is simply running down?  I have had / seen this fail at
least 3 times.

Additionally, is it the crush washer up on the rocker arm oil feed causing a
leak behind the valve cover gasket and running down behind?  Seen this at
least 3 times as well.

These seals on the 6 cylinder cars are acutally a secondary rear main seal.
The original scroll seal is still there. Usually if there is a leak after
installing the aftermarket rubber seal it is not the main seal. It is
usually something else.  

To leak 2.5 quarts of oil  in 100 miles is major. I would be looking at
other places first. Get some UV oil dye from the local parts store and put
in the oil. Then look to see where it is actually coming from.

Oil flex hose to gauge, rear of valve cover, etc.  Also have seen them leak
along the side of the rear main cap to the block, if they are not sealed up
correctly.

If it is the rear main leaking that much oil the seal will never stop it.
You probably had to little clearance on the rear scroll and the seal surface
is damaged.

When we rebuilt my BJ8 Engine I bought the Oil Seal from Moss and my
machinist friend installed it. I am confident he did a good job drilling and
tapping holes etc.  I had hoped that I would not have rear crankshaft oil
leaks.  In the past year I have driven the car a little over 1,000 miles 25
miles at I time and recently noticed those infamous oil spots on the
driveway.  Today I visited my British Car friends at Tech Central in Bonita
Springs a 100-mile round trip on I-75 nonstop at 65-75 mph.  Fortunately, I
carried 2.5 quarts of oil because I had to use it to fill the crankcase when
I got there and had to add 2.5 quarts when I got home.  In addition, I
notice the clutch slipping in 4th gear in overdrive if I accelerated.  No
doubt caused by oil on surface of the friction plate.

When I got home the weep hole in the transmission bell housing was producing
one oil drop every three seconds and when running the engine at fast idle
one drop of oil every second.

Has anyone had a failure using this seal conversion kit?
