Hi. Thanks for using JA! I will try and help you out.


Could you get me the engine serial number please?


If you do not have it, that is OK. I just want to make sure if your engine is a single turbo or twin turbo.

Customer: replied 5 years ago.

I had a type error on one of the specs. The nuts torque to 28 foot pounds, not 18. Sorry for that.


The heat shield that is on the manifold torques to 18 foot pounds.
