Exhaust Nuts

If memory serves, you are not supposed to reuse these nuts after the exhaust system has been removed. 

This is on fiche 18_0898 EXHAUST SYSTEM item #3 Hex nut M8 SW12.

Copper Exhaust Gaskets

Every time you remove the exhaust you have to replace these copper crush gaskets. Make sure that the old gaskets are removed. They can sometimes get stuck up in the head.

It's part #2 on fiche 18_0898 'EXHAUST SYSTEM'. It's called "Gasket ring C32X40".
