front crank shaft seal

[agmgranturismo2006]

i recently replaced the front crank seal,oil pump seal,oil pump o-ring and also oil pan seal is renewed but still there is a minor oil leak from the bottom of the timing belt plastic cover that oil leak is present when the car is running cold and stop once it gets hot its just few oil droplets and the oil is not getting low on the stick i think the front seal is leaking again but its a horrible job to open that place again can i leave it to the next timing belt change ?

Generally a leak near your timing belt will mean that you will be changing your timing belt sooner than expected. Oil and belts don't mix to well.

After changing a cam and oil pump seal on my 89 celica it took a couple days for the leak to fully stop. Then of coarse it started gushing oil out of somewhere else because old 3s-fe engines are so forgiving that way.

Let it be for a bit and see if it will stop as the seals swell and wear in (use dino oil not synthetic to help swell the seals). I know it's a PITA to get in there and I would probably see what happens after a week of driving. If it's not stopped by then it probably won't stop. And you could end up stranded from a snapped belt a lot sooner than the recommended 60k change.

In the end it's your choice.

Seems strange to me that it stops leaking when warm though. I would think it would leak more warm because the oil is thinner......

I've never seen am oil seal "fix itself." If it leaks its an installation or size error.

Two things come to mind. Did you oil up the seal AND the crank on installation? Putting a seal on dry typically folds or tears the seal lips. Also if the crank sealing surface isnt clean and smooth it will leak. Often there are deposits, or if the old hardened seal has been in use for a number of miles, it will wear a groove in the crank.

You should be able to carefully pry out the leaker, clean everything up and reinstall a fresh one.

Oil and timing belts do NOT mix so you should replace the belt too. Put on a fresh one AFTER you get the leak fixed.

i already made all the precautions when installing the new seal also used original parts i am already checking the oil every trip and i also check the timing belt by opening the top plastic cover frequently its always clean with no oil traces
