Ok I have been in the process of having my engine rebuilt. I sent my head off to be cleaned, inspected, flowed and have the combustion chaimbers and valves coated. The inspection came up with bad exh. valve guides. I have bought Ferrara valve guides both intake and exh. On the package for the guides it says to use Ferrara seals..my question is MUST I use them..I bought an oem mitsu engine gasket rebuild kit that has the oem seals. can I use the oem or must I use the Ferrara seals?

 

you should be fine with the oem ones. im not gonna mention any names on here but a salesman from a vendor on here tried saving me a few bucks once and told me they are all the same.

 

thank you good sir.

 

Are you running dual springs?
