I used a larger square seal I had and it seems to have sealed but I cant build up much pressure and I cant find any leaks. I need to be able to flow more air in the system as it is going somewhere. I had it to 10 ish LBS.

Have you pressure test the system? Is the turbo spinning freely?

Yes I have been pressure testing it. I cant get it past 10 lbs with the compressor. it seems to be leaking out but I cant find anyplace. everything that was leaking I fixed. I don't hear any noise either. I kind of think its leaking out in the cylinder or valves? I also don't think the shraider valve allows for a lot of air to flow so that does not help. I plan on turning the engine over and pulling the center out of the valve and pump it up to 30 or so lbs.

The system will leak down. The only way to get it to hold would be remove all the push rods and hope that your valves seal 100% which is highly unlikely

I cranked the engine over as I could hear air in the exhaust, it pressured right up to 25 psi with no leaks I could find.
