Im stuck! i have three sets of rockers here...

One is from my old 998 engine,

One is from my old 1275 MG engine,

One is from a 998 engine that i took it off tonite (to compare)


They all look exactly the same!!!

I need to find out which one to put on my engine (1040cc 1litre block with turbo 1.3 head)



is there any difference i can look for??

Sold the turbo and seeing what the C20XE can do!

Near Lincoln

they look slightly different spacing to me. there is a difference to 998 and 1275 spacing. as long as you get the set that match the valves then it will be fine. they;re all the same lift etc.

Is it A-Series only? I think it should be...
So when some joey comes on here about how his 16v turbo vauxhall is great compared to ours, he can be given the 'bird'...

Pretty sure they are all the same,It's only the roller tip ones you have to play with the spacing,as the roller is only on 2/3rd's the width of the tip.so you change them round for 1275 or 998 inlet to exhaust valve gap.

Near Daventry, midlands

they are indeed all identicle, however check for wear, slack in the rocker on the shaft and rebuild if necessary. New shafts and selected rockers from a few old sets will see a vitrually brand new set for only £10 (new shaft cost).

The bit you mention is a grub screw, it locates into the rocker shaft to stop it from rotating or moving axially.

If I were you spend 10 mins and take a set completely to pieces, you'll learn far more about how the work and how they fit together doing that than we can teach you on here. After all, you have got 3 sets to go at.

theres no difference between them, i remember posting jsu that on miniclassic years ago whwen i noticed there was no difference and i remember a few regulars dissagreeing. the only difference(if you can call it that) is that the wear on teh rocker tip's will be different from 1275 to 998 due to valve positioning.

turbo 16v k-series 11.9@118.9 :)
