Plowboy Posted June 29, 2017 Share Posted June 29, 2017 I have multiple packing leaks on the exhaust manifolds and exhaust manifold piping on my '85 RW with a '94 E9. The manifold -to-head gaskets aren't leaking, but all the doughnuts are. None of the manifold bolts want to break loose. Anyone have any suggestions on getting them out? Looks like trouble.

wrenching4life Posted June 30, 2017 Share Posted June 30, 2017 I had the same issue, soak them good like Carlotpilot said, all the joints and bolts. If you have no luck apply heat on the manifold where the bolt your working on is and carefully work back and forth, none of mine were seized in the head only in the manifold, I also cut a socket in half to get into those really tight places. The heat is what worked for me. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/50334-e9-exhaust-manifold-gaskets/#findComment-373770 Share on other sites More sharing options...

Mack Doctor Jr. Posted July 3, 2017 Share Posted July 3, 2017 Heat the bolts up with a torch and use candles to break them free.
