You need to get all new intake gasgets and start over. Use a hone and smooth the surface on the back of the timing cover where the rubber washer rests. You may have a deep scratch which will seal if you use a gasget sealer. Give the sealer some time to cure before you fire up the engine. Make sure you use the correct torque pattern and torque readings on the intake. Sometimes you have to use a thick washer on the long bolt that pulls the intake to the timing cover. Sometimes the hole is just not deep enough and the bolt bottoms out. You could also trim a 1/16 inch off the end of the bolt but make sure you have at least 5/16" of threads actually used to pull with. The TINK TINK is most likely a lifter hitting the inside of the cover. While you have the covers off look for witness marks of where the lifter was hitting.
