Compressor Bypass Valve Missing Bolt

Post by nickelghandi »

While chasing some low/sporadic boost on my 1999 V70 AWD, I decided to inspect the CBV. When I got the heat shields off, I found that one of the 10mm bolts is missing from the CBV. That seems to indicate the source of my erratic boost.

The trouble is, I now cannot find the 10mm bolt online anywhere. IPD, FCP, Ebay, none of them. I only need one, but I'd imagine I have to buy a kit. Anyone on here with a spare? I'll pay lol.

I recall those being 6mm 1.0 x 20 mm long bolts. you can get those at home depot, lowe's, tractor supply, etc. it is not a special bolt. Get a flat washer for it so it doesn't dig into the aluminum of the bypass valve body.
