Stock seals in 2mm are three piece which are junk but the stock 3mm seals are two piece and they are very good quality.

  Dave were they 2 or 3mm seals ???

Hi Ken,

 

I think we were talking about Chuck's most recent problem, not Dave's. 

 

As for the seals, IIRC, Mazda made 2 and 3 piece 2mm seals over the years.  I can't recall which years though.  Looking at the Mazdatrix site, they list 86-95, 2mm, steel 2-piece Mazda seals.  I don't see a listing for 3 piece (maybe because they're junk).  They also list aftermarket 2-piece 2mm seals as well, so if he bought them from Mazdatrix, they could have been non-Mazda seals.

  Yes its Chucks, to many blown engines out there and got confused.

  I was not aware that Mazda made any two piece 2mm seals until the RX8 came out, now the seals they offer for the early engines are the same two piece seal that is in the RX8 but I don't think they were out at the time that Chuck put that engine together but maybe.

Ken,

 The RX8 apex seals are much shorter in height than any previous seal. I think you would be having a bit of compression problems using the RX8 seals in anything but RX8 engines.
