Re: [Peugeot-L] Re: 405 S questions

all PRV is full aluminum from the developement and all the way to the 24 valve version. Head and block.

N9T, heads is aluminum not iron. The block is iron for sure. tj

  Interesting... I thought all PRV's were made of iron...

  Maybe only the heads are iron (ala N9T)? hmmmm....
