oil leak

Post by eastkytriker » Thu Jan 09, 2020 10:37 am



Engine oil leak on 1990 gl 1500 on the front of engine around the water pump. Drips hang on the bottom of water pump. Nothing coming from weep hole and oil filter not leaking. Any info appreciated

Not from weep hole?

How bad is it?

Any trails?

Oil can start up high, follow crevices, to a low spot, then jump off onto the floor.

Water pump is in a low spot.

I'd spray it clean and start engine (in a well vented area) & have a look as it's running. Block wheels (or chain trike to a post or truck) so no accidental run overs. Those aqua shields might limit your view so you might want rear wheels in air with the rear axle on jack stands. Strong LED flashlight in hand, clean & scratch free safety glasses on too. What I'd do.

… & Have a Safe Trip!

This time of year when it gets cool the aluminum shrinks as does any metal. The seal on the waterpump can weep a little oil before the antifreeze starts leaking out the weep hole.

That looks like it is leaking from your crank main seal. That's what's underneath that cover. In which case, your timing belts are likely contaminated with oil as well.

Remove those three bolts and pull that round cover off, it will reveal the crank pulley. See if you can view oil on the case inside there.

This is the pulley under that cover:

I removed the cover and it looks clean and dry. Can't see a lot in there but didn't see any oil

That's good news then!

I would use brake cleaner to clean any oil or grease off, then use some talcum powder to coat the area, and run the bike again. Wherever the oil is leaking from will make itself known right away.

I've seen so many GLs with oil on the engine that had it actually coming from blown fork seals. Check 'em.

WingAdmin,
Brake cleaner and powder on the area where the oil is leaking?

The brake cleaner washes away any residual oil and leaves the metal clean and shiny. The powder then shows immediately where the oil leak is, as soon as it starts leaking, making it easier to trace.
