New car problems

Just because it was rebuilt recently doesn't mean it was done correctly unfortunately

 

Agree completely, and as I'm going through everything in this thats becoming evident. I guess if he couldn't tighten bolts down properly, I cant expect a motor to have been built properly. Is there any way to tell if it's ringlands for sure other than pulling the motor?

Whoever built it did a pretty decent Job, just by looking at . I also recommend getting occ to relieve pressure of crankcase and for your boost problems check the wastegate it's supposed to have 3 springs for 18 psi since your running on spring pressure itself I bet that's what it is , he might have put one or two instead of 3. The colors if I'm correct should be white, Blue , gunmetal , also try contacting the last owner he or she may be able to help you more

 

Yes you can check your rings by doing a leak down test. It will probably tell you if a ring is bad
