Do any of you know Volvos? Plz HELP Exhaust Manifold Replacement
Hey all -- I have a normally-aspirated 5-cyl 20v 850 Wagon, which recently developed an exhaust leak at the flex pipe, which I gather is exceedingly common. Coming from a Porsche-tuning background, I figured, "well, as long as I'm replacing, I might as well upgrade," and bought the exhaust manifold-with-flexpipe replacement from OBX Racing. The part fit beautifully except for one detail: the Secondary Air System port on the side of the new manifold seems to be a totally different size diameter than the OEM part. What's the solution here? Is there a slight model-year/trim difference that I missed? Is there an adapter that I need to buy? Or can I get the Secondary Air System pipes from a different-year/model/trim Volvo in order to make it fit?
Any guidance you could offer would be most appreciated. Thanks in advance!

If it's any consolation I just did a similar repair on a V70, and mine didn't fit either. I had to open up a couple of holes.
Try the dealer, there are lots of variants of that engine.

So, what did you end up using? A pipe from a different year?

Get a picture of the connections on the exhaust and the line. Are you trying to hook up the SAS line or the EGR line?

Not your problem but you can put it in your hip pocket. Transmission mount and passenger side engine mount were played to the point where the drive-train sagged and stressed the down-pipe joint on the turbo forcing a leak.

Here are some pictures to illustrate what I'm talking about.
In the first picture, the port to which I refer is on the lefthand side of the manifold. The port on the NEW manifold is too big in diameter to fit the stock pipe (picture #2). As a temporary solution, we plugged the port with an 18mm drain plug (picture #3), which I've since learned a lot of Volvo owners do exactly the same with zero running problems or dash lights.
