Default Valve Cover Gasket Question

Just replaced passenger side valve cover gasket and plug gaskets with fel-pro kit and new OEM bolts. Tightened following the suggested order and started leaking oil like a mf after all hooked up from the bottom left area(closest to turbo). Iím wondering if I mixed up the bolt sizes. When I installed new I put the longer bolt in the bottom left and Iím trying to figure out if it is supposed to be the shorter bolt. If anyone has any insight Iíd appreciate it. Thanks

from what i remember they are all the same...normally a leak would only occur if the gasket fell out of the groove...

Mine leaks as well. I bought oem gaskets,half moons,new bolts and Fujibond. Normally I'd use ultra black but I decided to do all oem. I followed the service manual to the t and the engine was out of the car at the time. Used a torque wrench too. Idk. I believe the two bolts at the rear are longer the rest are the same.

Always add some FUJIBond in the corners, gasket never seals corners right.

In my experience the oil keeps slowly draining out of the head along bottom so the fujibond can't seal. What I did was pull the valve cover and let it drip for a day. Then I still had to shove rags in there to dry up some oil that was still dripping. Get the surface CLEAN and DRY. Apply fujibond where the manual states plus along the entire bottom gasket surface. Reassemble and let sit at least overnight so the fujibond can dry. (I do 24hrs myself).
If you're going through the trouble to do this use an oem gasket. Also hondabond is as good as fujibond. Use whichever you can find.

Agree with Router Rob. You need both the surface and the gasket PERFECTLY CLEAN before you apply gasket maker and torque er down. Use some brake clean on a rag.

Just don't dirty up the cams!

EDIT: The frontmost 3 bolts are shorter, at least on my D25 EJ255
