DIY 1998 Volvo V70 Exhaust Manifold Replacement

Alright, my exhaust leak has been chronic for a few years, as it turns out, it is a leak at the Flex Pipe, just in front of the Catalytic. It gets worse and noisy, so I decided to tackle it.

Search forum for “OBX Exhaust Manifold” brand, about $200 on ebay etc., many people seem OK with it. I could not find any long-term report (such as 5 years or more) of happiness with OBX, also from my research the Honda people have some issues with OBX. Since this is a job I don’t want to do again for another 10 years, I decided to go with Volvo OEM because the OEM held up for more than 10 years!

Sunroof Seal Repair

After peeling off the gasket I discovered that the metal sunroof frame was severely rusted and had begun to separate from the glass. The glass is bonded to the frame with a very hard rubber like sealant, water seeps under the sunroof gasket and sits in the depressed area of the frame causing it to rust.

To repair this I first scraped/filed off as much loose rust as I could and pried the frame as far away from the glass as I could without breaking anything using wooden wedges and continued to clean as much rust out as possible. I then applied a rust converter to the remaining material.
