it seems when engine is cold it leaks from the spring bracket connection! the one between the cat and down pipe



could this be due to a worn washer/gasket in the braket?? as it did seem pretty knackred last time i saw it??
were could i get a new one or somthing to seal it up with??
and is that part number that i need, BLG65??

is that the connection with the compressed wire wool type seal? would imagine they could corrode a bit.

its in good condition, its not rusted bad or corroded...
its actually leaking from the "connection" of were the down pipe bracket joins the Cat bracket which are held in place by two spring loaded bolts?

it could be that i just need to tighten up the bolts? or i think more likely the Gasket needs replacing?

AND if it is the gasket that i need, is that part number labeled- BLG65 be the part i need??

Id do both to be honest.

You need the Cat to front pipe gasket (vaux part for 1.6 is 90448071) and new bolts (vaux part 90280056) and new springs (90234204).

Im not sure whether the springs and bolts come in a pack of 2 under that part number, better check first.
