    Installing a new turbo, manifold and wastegate and noticed there is oil leaking from here. How can I fix it? 20210120_212945.jpg

    Your number one runner looks extremely wet. The bottom center stud runs through the head so can leak from there if you’re using a short bolt instead of the factory stud. Only other guess is head gasket or valve stems leaking pas the exhaust manifold gasket. How does the inside of the exhaust manifold look?

    Your valve seals are shot, judging by the oily exhaust port.

    Its a relatively easy job. I replaced mine last winter. There is a valve spring compressor tool made for the 4g63 that allows you to remove the springs without removing the head.
