Problem fixed: Rusted exhaust msnifolds.
I have a 1988 OMC Cobra 4.3 V6. These engines originally used a one piece manifold/riser unit. I liked these because there was no riser gasket to leak and they were simple to install. I am in a salt water area and we have to change exhaust manifolds every 5/7 years or else you can get water in a cyl and when in salt water this is really bad. The problem was the original OMC one piece units are NLA. I did find out that GLM was selling a conversion kit using a Volvo style center riser set up with a 4" to 3.5" 90* adsptor. I could have used the GLM kit but I have heard of fitment issues with their exhaust manifolds. So what I wound up doing was replicating that kit but using Barr manifolds and risers and OE Volvo parts for the 90* exhaust adapter and hoses. It all fit perfect. A little pricey but in salt water it does not pay to scrimp on the exhaust system.
