93 camry V6 chasing oil leaks

[brian long]

Hello, I think I'm down to the last leak on my 3.0 litre. I'm sure it's motor oil, as the dye they put in when the cam cover gasket leak was diagnosed is still in it, and the puddle on the floor glows under blacklight.

replaced:
PCV valve
cam cover gaskets (paid the local Toyota garage) ouch!
distributor housing o-ring

*the oil filter adapter is not leaking.

The oil drips off the passenger side driveshaft inner CV joint. Can't see where it's coming from. any ideas? Thank you

Rear valve cover gasket. If camshaft seals were replaced and not leaking - I don't know what else it can be there. Ah, your engine has a distributor, is it somewhere there too?
If your oil has dye in it then just clean the oil, wait while it starts to leak and using the light find the source of the leak.

I would look at your timing belt cover and see if it is wet with oil as though some were coming from underneath it. I would venture a guess it is (if you have replaced those other things correctly and you have more than residual buildup running off as it heats up). Underneath the TB cover there are oil seals around the camshaft(s if it's a 3L V6 with two valve banks), crankshaft, and an oil pump O-ring and oil seal around the shaft for it. Hope this helps.

I assumed by that you meant the valve cover gasket, which is the first suspect if you didn't already do it.

3VZ doesn't have separate oil pump seal or shaft, it is on crankshaft (like 1MZ). And the crankshaft is way far from the axle.
Are you sure it is not the P/S fluid? Just asking... The P/S pump is right there and either the pump or one of the hose may leak.

My bad. I was thinking of the 5SFE's that we have, but they're 4 cylinders.

This. Common problem with that engine. My wifes '93 does it but it's going to have to wait until I do the rear plugs.
