hello, does anyone know if the alum piece that covers the exhaust manifold has spacers btwn it and the manifold or does it bold directly onto the manifold (with washers)? and i assume that this piece is there to dissipate heat and protect the plug wires? thank you chuck

there are no spacers, however usualy the bolts break here due to heat bonding them to the holes. The best solution is to run the E30 1983/84 318i exaust manafold gasket. this has a built in heat shield and is easier to work around.

Use anti-seize compound on the bolts. I use it wherever I put steel bolts into aluminum or where the parts see high temparatures, like the exhaust system.

You're going to have to be careful because the manifold is much hotter than any other part of the car (besides the combustion chamber). Use something that's made for exhaust manifold studs, possibly graphite based or possibly something for an O2 sensor bung. Also maybe it wouldn't be a bad idea to use a spacer of sorts out of soft metal or something so that the bolts don't break on their own. Once they brake off and rust up you'll almost never get them out unless you drill & tap new holes.

Get some stainless steel bolts at the hardware store and goo 'em up with antiseize compound; they'll come right out five years from now.

cheers
