Silly Rocker Question
Turbo Mini Forums

Is there a difference between 998 and 1275 rockers. On my 998 with a 1275 head I had some 1.5 rockers. A bush has gone on one of them where I dropped a valve. So I dug around the garage and put on a set I found.

The question is are 1275 and 998 rockers any different. I don't think they are as the cams are the same, but it did get me wondering. Certainly the wear marks on the rockers i have put on don't align exactly with the valves so maybe the rockers are different? Anybody know?

yeah, the spacing is different, but nothing a bit of shim-tinkering cant fix

im on the look out fpt 1.3:1 roller rockers for a small bore, nick swift thinks he may have a set in a parts bin, but other than that they are like rocking horse shit

Perhaps the ones I have are 1275 ones then as they seem to fit more or less ok.

im positive i tried 998 rockers on a 12g940 and they were fine, jsut the valves wernt bang in the centre of the rocker, but im positive standard 1275 rockers are like that anyways. though was quite a few years ago now :S

they are just to the side slightly, but as said before, nothing you cant fix

The sintered ones aren't, but the pressed steel ones are. The 998 ones have a round pad whereas the 1275's is oval.

Well I have the sintered ones and they look ok. It was only that the wear marks looked slightly off that I questioned it.
