RE: O.S .46LA Head Gasket Help
Replaceing the gaskets are fine if you like but yes I did look at the brake down and it is quite obvious that there is only one gasket (alum shim type) and the backplate gasket is sold along with it in a single package. Paper gaskets an not used for head gaskets on modern engines.
Also if you order the two gasket set do not use two gaskets on the head that would be a mistake that will present even more running problems.
There is only one head gasket used on that engine and is an aluminum shim type and if the order talker said there are two then she or he is wrong. They are just order takers.
If the six people at your club said that engine has two head gaskets well then thats a bunch of "crap"
