I replaced the exhaust manifold gaskets today on my '90 300SE. Unfortunately, I now have an exhaust leak. I think it's the forward down pipe. I thought I had it matched up well before tightening it up.
I loosened it and tried again, still leaking. I tried using soapy water to see if I could find where it's leaking, no luck.
I did notice some wear on the manifold at #4 cylinder, I cleaned it up and it was very minor.
Any suggestions as to what to do?
