Default Evo cam cover seepage

Yup, my second attempt at installing the cam cover is seeping some oil. First try was my fault (the two long screws LOOK the same length, but they aren't). Second time, it appears I didn't get the screws tight enough. Now that the gasket was "wet thru", it continues to seep even after retorquing the screws, so I guess I get to do the job one more time.

Since I've always gone into the gearcase to replace a cam or cam bearing, I've always removed the pushrods first. Is it possible to remove the cam cover with the pushrods in place? In this case it would save me a lot of time and trouble if this could be done. Is there some position the cam needs to be turned so that the force from the valve springs is balanced and at a minimum, so the cover can be removed/installed? Or am I better off just biting the bullet and doing all the extra work?

Put the notch in the end of the cam at the 5 o'clock position and you can pull the cover....make sure you push in on the cam as you pull the cover so you don't pull the cam out.

Thanks, Spanners, I knew you would have the answer. I thought I had read that here before but wasn't sure if I remembered it correctly.

You see, stuff like this can't be found in the factory manual, but it can be found here.

And make damn sure your using the right gasket!....

There are two types for Evos and if you put the wrong one onto an early Evo it will **** oil out of the cam chest everywhere (do not ask me how I know...lol)

OK, stupid question of the day...how do you know when you have the notch at the 5 o'clock position if the cover is on?

I assume you saying have the notch in the cam in the 5'oclock position before removal of the cover. Is it visable after the cam plate, rotor and inner cover for the electronic ignition are removed? Thanks, YD

What he said you pull the points cover, then the inner cover, then the sensor plate and then the timing cup...if you didn't know that then you probably shouldn't mess with it...

The man knows of what he speaks. He turned me on to this little trick when I started chasing my oil pressure problem. Worked like a charm!

+2 to that idea...works a charm. Just make sure you hold the cam in place as you remove the cover as sometimes it tends to pull out with the cover.
