Speaking from expierance again! Get a used one from a wrecker for about $60 Cdn! Add some aftermarket gaskets too. READ: Attention EGRless Owners in this section..... http://www.bonnevilleclub.com/forum/...pic.php?t=6566
Continuing to drive it with a cracked manifold will cause internal damage over time. For one thing you're losing POWER & valuable gasoline. Secondly, you're slowly eating away the exhaust valve for that cylinder too due to the temperature differeance from Oxygen ENTERING the manifold & causing a hotter temperature to the back side of that cylinder'* valve!
I've been there & had to fix it already.....Hence the write up in this section about this & the exhaust valves too.
