The front valve cover on my 3800SC is leaking oil at the right bottom front corner. We have a few gaskets on the shelf ready to go. I've never changed a 3800SC valve cover gasket without dropping the cradle down and barring anyone's suggestions to get around this, that is what we intend to do.
I was just wondering of anyone has had success replacing a leaking front valve cover gasket with the engine in place. Might consider a cradle tip but not sure if that has worked or not. Just trying to avoid 8-10 hours of labor just to replace that gasket.

We did the cradle tip thing (dropped the back, left front hooked up)when we developed a leak at the track. Worked very well. Didn't take much of a drop to gain proper access.

Thanks. I thought that this method would work. Here is how I envision the process:
1. Disconnect dog bone(s) I have two
2. Lift up car just until rear wheels leave the ground ( we have a lift)
3. Remove CAI coupling
4. Remove rear wheels
5. heater hose at LIM.
5. Engine to pipe hoses/coolant?
5. check all wires for enough slack.
6. loosen front cradle bolts
7. Remove deck lid??/
put jack on rear of cradle support cradle and remove both rear cradle bolts. Lower rear of cradle down
It sounds very doable but this is my first attempt at this. Is that the process that you used???

Weird. I've never had any issue. I've even replaced head gaskets with everything still bolted in place.
Should take 5 minutes, tops.

The job may not be a big deal but most of the work that I have ever done on a 3800SC in a Fiero has been with the cradle removed and/or the engine on a stand. You can do an effective job of injector changing, pulley changing, supercharger removal and even intercooler installation etc with everything in place but I believe that replacing the front valve cover gasket will take more than 5 minutes. First off the idler bracket at the right side of the front valve cover must be removed to gain access. Deck lid most likely must be removed and harness swung away too. Maybe that would do it. Just thought that I'd pose the question before I dig in.

For the firewall side if you remove the deck lid it is easy to do as long as the GTP ign mod/dog bone bracket has been trimmed enough to clear, on the trunk side it is a pain as you need to remove the stock 3800 alt bracket if you are using one. Either way loosening the nut and bolt on the bracket for pulling the engine helps the valve cover clear when removing. Dan
