So I put thay new gasket on. Used some rtv, didn't know how tight I should torque those twork bolts. Still leaked. Actually worst. Any ideas? I have another gasket so I might try to redo the job tomorrow
Before you start make sure none of the bolt holes in the head are stripped out. If they are get longer bolts and tap the holes deeper. This isn't a bad idea even if they are not striped out. It can prevent such damage in the future. I used "the right stuff" on the aluminum half moon plug at the end of the exhaust cam before I started.
I have had best results doing the following:
1. Thoroughly clean everything aluminum with alcohol or brake cleaner. 2. Wipe down the gasket with same. 3. Using black rtv Apply a thin continuing bead around the entire inside lip of the valve cover gasket groove. 4. Insert the gasket in the groove and aligning all the holes. Evenly apply light pressure with a piece of plywood or other similar object. 5. Inspect spreading pattern. Add a little where nothing came out. Wipe smooth any large gobs came out. Pay particular attention to corners. Return to step 4. until your satisfied with the application. 6. Apply a thin continuing coating to the head and spread thin and even with your gloved finger. Areas you can't reach with your finger apply silicone to gaskt instead (around cams in corners ect.) 7.install cover and lightly thread in all bolts. 8.using a nut driver snug bolts in a pattern as if you were installing cams or a head. (Alterating side to side using inside bolts as well as perimeter bolts) make at least 2 passes to make sure it lays down evenly and you don't strip out the head. 9.let it dry for at least 12 hours before running the engine to make sure it cure properly 10. Boost on.
This process workes well for me. I have had way too many new dry gaskets leak on me to ever not use rtv everywhere again.

Ha. LOL ok. That's what I get for not reading all the posts.
I tried a bunch of times to seal mine with no luck. There are special crush washers for the bolts that people say you need. Other people say double up the gasket. I've heard people say cut the little tab off the outside of the gasket. Every turbo 4G I ever owned had a leak here. I welded a 3/4" NPT fitting on mine after the 3rd try to stop the leak. Its working well like this:

I'll also keep that in mind. But.... I'm referring to the other side of that line. The connection to my turbo. I applied the gasket. A decent amount of rtv. But it was tricky getting the gasket on while under the car. Or above it. I just tightened it till I felt the bolts where pretty snug
