I've just picked up an '99 850 TDM with 48K.
There's not a lot wrong with it, except for:
It has one of those weirdly shaped 2-1-2 exhausts with the looped connector pipes (no collector box), it has been welded where the 1 goes into 2 join, but it's still got holes and it blows.
At idle with a hot engine, the engine 'pops' approx. every three or four seconds, could this be caused by the blowing exhaust?
I'm thinking of a Delkevic 2-1 system from ebay and wondering if this could cure the popping.
The 'popping' isn't the exhaust blowing, it's quite a distinct pop every few seconds as I sad above, could it be something more serious?
Thanks
