Yaesu FT840 Frequency drift problem ?

Hello all, I have a friend who recently bought a 2nd, of third hand FT840, exelent condition and all that, it really is in good nik! Anyway It drifts like mad, after 10-15 mins of intermittant transmit, like today on 10 meters. 28.470 was the frequency , and at one point he was transmitting on 28.473.6 a massive drift, then just as quick it went back to ruffly where we were over the space of about 20 mins or so ! I have looked up on mods.dk and it mentions the use of a piece of styrofoam cut snuggly around the area ? vco block or something ? Anyway is there any help out there in radio land, what is the problem here,and will it be easy to sort out ?

73 de Andy M1KMC.
