Oil underneath the oil pan and front cross
member of my 1978 Jaguar XJ-S was the first clue that something was amiss. high

under the V-12 at four thousand RPM will make grown men weep. The trail of oil
from underneath the crankshaft damper was unmistakable. The seal would have to
be replaced.oil sealing.
I recommend removing the radiator support, fans and fan shroud. It’s critical that you have fairly good access to the front crankshaft area.
In order to remove the crankshaft bolt, the engine must be prevented from turning. There are a number of ways to accomplish this. Don’t use a screwdriver to jam the ring gear teeth, you might damage them. My recommendation is to remove the torque converter inspection plate and use a vice-grip to clamp down on the flywheel ring gear. Turning the engine will cause exhaust pipe to stop the rotation of the vise grip.high pressure auto oil seals Easy to use.
Remove crankshaft pulley. The pulley has a hex nut that bolts to the damper. (See blue arrow 2nd photograph). The hex nut installs with two bolts with spacers (red arrow, 2nd photograph). This hex nut assembly must be removed to gain access to the crankshaft bolt.ring seal.
The crankshaft bolt requires a 34mm socket. I was unable to find this socket in a 3/4″ drive. I used a 1 5/16 inch six point 3/4″ drive socket instead.
Even with a breaker bar attached, I had to augment leverage with an extension to get the crankshaft bolt loose.nok seal.
Use the appropriate puller to withdraw the crankshaft damper.high pressure auto oil seals Easy to use.
The special damper “cone” is now visible on the front of the crankshaft. Remove the crankshaft cone by pulling straight out.
The damper assembly uses two identical keys. One locates the damper to the cone. The other locates the cone to the crankshaft. Remove the crankshaft cone key. Note the keys are identical and are positioned on opposite sides on the crank / cone assembly. Save these keys. Tap out gently with a small screwdriver if necessary.viton seal.
At this point I found it easier to work from underneath the car. Use jack stands or ramps. You will be under there for a while. I also removed the oil cooler return hose for better accessibility.high pressure auto oil seals Easy to use.
