Does a 931 S2 (ROW) have a check valve in the vacuum lines? (except for the one in the brake booster)
If yes, where should it be ?

As far as I know only the S1 has this. _________________ red 924 and not red 924 |

Correct. Only the S1 has vacuum/retard via the distributor and the red/white check valve is required to manage the pressures. _________________ 1980 931 - forged pistons, Piper cam, CGT turbo, 951 ducted FMIC, custom intake, Mittelmotor dizzy & cam pulley, H&S exhaust, GAZ Gold, Fuch'ed, Quaife LSD
