RogerH Posted June 9, 2010 Report Share Posted June 9, 2010 Hi Paul, the W/S manual states 0.004" - 0.005" (I think). Is your protrusion (pardon the expression ) before or after fitting the head. Ali Fo8 seals will squish a fair bit. Don't forget to cover them in 'Welseal' or similar otherwise they will corrode in front of your eyes. Roger Quote Link to post Share on other sites

Ade-TR4 Posted June 10, 2010 Report Share Posted June 10, 2010 Hi Are they standard or "soft" Fo8s? Standards should be 4-5 thou. Cheers Ade Quote Link to post Share on other sites
paul958 Posted June 10, 2010 Author Report Share Posted June 10, 2010 I would say they are aluminium not steel ones. Quote Link to post Share on other sites
stuart Posted June 10, 2010 Report Share Posted June 10, 2010 FWIW TR Shop do keep copper FO8 seals which are nice and compressible and dont suffer from rot problems so bad. Always worth a good coating of Wellseal anyway when fitting them. Stuart. Quote Link to post Share on other sites
