    Misfire in 2&5 comp in 1&6 90psi WTF

    I am about to pull my VC and re torque my head bolts. Before I do has anyone running a Cometic MLS and ARP's had to re-torque after winter/summer? It seems like I'm not getting good seal on the ends. Head was rebuilt and milled and RA was spec'd o block and head, polished block for RA and coated MLS with Permatex copper gasket sealer spray and installed head per ARP instructions. 84ftlbs in 3 steps of 28. I do have a vanos mechanically stuck code I have never attacked but the timing is still dead on IDKWTF hope I don;t have bent valves I haven't had any shifting incident or drive the ever loving shit out of my car. I use my power but I don't bounce it off the top or anything.

        Do a retorque just to be safe. Doesn't hurt to make sure and takes all of 30 minutes tops.
        Have to pull coils and plugs to do a leak down anyways.

          Well it was fun for a few months, think I'm gonna park it and be happy the S52 is in the car and one less motor in my garage. With the M roadster project, the Durango needing a rebuild and still have a few skis to get running before May. Maybe I'll get into the motor when I swap the dash this spring idk.

          I fucking love to hate this car so much.
