Oh, dude, replacing the distributor seal on a 1991 Previa is like a walk in the park... if that park is filled with angry squirrels. First, you gotta disconnect the battery, remove the distributor cap, mark the position of the rotor, take out the distributor, replace the seal, put everything back together, and hope it starts up without making weird noises. Easy peasy, right?
If there is leaking around the base of the distributor, and you will need to replace the seal. The distributor oil seal is a paper gasket or rubber O-ring, and the distributor is removed to replace either one if the seal is leaking. It is easy to change, just remove distributor and change the seal.
replace the cap, it most likely has a hairline crack or bad seal.
Yes, That would be the easiest thing 2 do.
There is probably a leaky connector seal somewhere or possibly a little water gets in the distributor, provided that your cavalier is old enough to have a distributor. Check the connectors, especially around the ignition distribution. You can seal connectors with a little silicon grease, but if there is any damage, just replace the part.
Remove the transmission and starter. Unbolt the flexplate from the crank. While you're at it, replace the rear main seal. Replace the flexplate and torque bolts to manufacturer's specs.
There is a rubber O-ring seal on the distributor shaft. You will need to pull that shaft and replace the O-ring. Fairly easy job. The O-ring will cost you about $1 if you can do the work yourself.
The axle on a 1991 Suzuki Tracker is a semi-floating design, meaning it has a shaft that is supported at both ends but relies on the wheel hub for additional support. To remove the axle to replace the outer seal, first, remove the wheel and brake components, then disconnect the axle from the wheel hub and the differential. Finally, pull the axle out of the housing, taking care to replace the outer seal before reassembling everything.
Front seal: remove engine or transmission and replace the seal. Rear seal, remove the drive shaft to replace the seal. Unfortunately, you typically only have problems with the front seal.
Remove the serpentine belt. Remove the harmonic balancer. Pry it off the crankshaft. Install new seal, replace balancer and belt.
