    Question regarding what Ferrari used on the 348 series as a sealant. My understanding is the factory sealant is white. Performing a major and transaxle refurb on my 348 spider. Removing the transaxle from the engine I noted red/brown silicon sealant on the large “O” ring that seals the engine to transaxle connection. I cannot picture the factory sealing an “O” ring with silicon. Also the same red/brown sealant inside the axle stubs where the CV joints connect. Cannot fathom purpose. Factory? Opinions welcome, thanks.

    spider348,

    The white silicon sealer was used only by the Ferrari factory on initial assembley and was called "Rhodoseal" It is still available today, made by Rhodoseal, but only in a reddish / brown colour. Basically if you strip a gearbox / engine unit and it is sealed with the white sealer you know it hasn't been apart before, however if you find the reddish / brown sealer it has been apart since leaving the factory.
