January 6, 200818 yr Hey, Should the head bolt studs need to be pulled to clean the head gasket surface area to replace the head gasket? Any re-torqueing required if I use new original Subaru gasket? or re-torque required if I use Fel-pro head gasket? Thanks...
January 6, 200818 yr Hey, Should the head bolt studs need to be pulled to clean the head gasket surface area to replace the head gasket? ... Usually I don't.... saves the aluminium block threads from wear..... You can if you wish. Just double-nut them and they will come right out. A razor blade and a 3M pad with brake cleaner will clean the surfaces up good. Any re-torqueing required if I use new original Subaru gasket? Yes, but most people don't. Add a few extra pounds. Instead of 47 (or is it 57??), go with 55 ft/lbs (or was it 65??) as your final torque. Just make sure the threads are chased in the nuts (and rocker bolts) and that the studs have been wire wheeled and properly oiled for torqueing. or re-torque required if I use Fel-pro head gasket? Niether required or reccomended. This is the route I personally go as these gaskets are VERY tough. I love every set I've used. GD
