GS400 Cam seal, bearing cap oil leak
1998 GS400
I'm trying to get someones insight and plan the repair.
I have a oil leak that looks to be coming from the front bearing cap, under the valve covers.
So I need to pull the valve covers and the bearing cap.
By pulling the cap I assume I compromise the cam seals.
Can the cam seals be replaced with out removing the cams?
Thanks in advance

I love responding to my own post...
After cleaning the residual oil from the motor, it may not be as bad as I thought.
The leak seems to be just a minor seep, something I can take care of with a good wipe down once a week or so.
It has been a year since I detailed the motor and this past weekend I noticed oil on the engine undercover and traced it to the front valve cover area.
Now, I believe I can wait and do valve cover gaskets, cam seals and reseal the end plugs and bearing caps when I do the timing belt job, towards the end of this year.
I still have a question, Can the cam seals be replaced with out removing the cams?
I think I know the answer but I don't like it...

My neighbor Lars with his fancy 430 might need them before me. He is over due on his timing belt and wants to do the cam seals (I can't wait).
Thanks, Brian I'll let you know...
