1997 12v wastegate line diagram

My trucks missing the line on the intake horn side by the valve covers. My truck leaks oil like crazy. I'm chasing oil leaks starting with the most obvious. Trying to get the waste gate back to stock from previous owner.

All you need to do is run a boost line from the intake manifold. The factory is from the compressor housing to the controller.

Is there any pics available. I know just enough to get myself in trouble. The truck has leaked oil since I've had it. And I've been reading about the crankcase pressures. I know this isn't a complete fix, but I'm hoping itll slow it down.

Old truck equals dried out gaskets, valve cover, tappet cover 2 most common to leak.

It's hard to pin point. I bought the truck for work. Took it to my mechanic to go over and make sure it didn't need rebuilt. He said the motor has very little blow by but some of the seals were bad. I haven't had a chance to clean the undercarriage yet. In the process of putting the starter back on. But I know the extra pressure isnt helping the oil loss. I'm thinking about getting patched up as best I can. Then putting it up for sell if I can get the right price

Tappet cover was replaced before I bought it. But yes I believe it set for some time. It runs great just have to keep a jug of oil handy. Got quoted 3 grand to replace all seals and throw a new clutch on just while it was apart. But if I go that route I'll just keep it for a toy
