Ok i will check it out and check the egr as well... I will say i am missing 1 bolt to the rear manifold could that be the ticking? Do all bolts need to be used for the rear manifold its ticking is come from the rear and it gets louder when i get on it
Um. yes. You need all the bolts/studs on the headers. Don't leave any behind.
If you completely missed one bolt/stud, just get one and put it in. No sense in changing the gasket when you didn't seal it right to begin with.
This will also jack with your tune. After I fixed my header leak my a/f went from a solid 11.4-11.5 to an awesome 12.5:1 a/f. Not sure if you have a wideband (you should) but it's something to look for.
