Boost leak noise after egr delete
This is on my 1996 delica l300 4d56. I did an egr delete with a egt sensor and boost sensor in the blocking plates. After the delete it’s has been making the Sound in the video at around 12 psi of boost.
I noticed one of the top block off plates bolt holes was somewhat stripped and I thought it was leaking. It still makes the sound after i tapped a new threads and was able to get it tighter.
It runs and drives just fine it’s just makes the noise.
All I think to do is go back in and make sure everything is tight. Any ideas would be great. Thanks
