Rockers hitting the rocker cover?

[Paul V]

I put my mini away about 2 years ago with a knocking engine, it started knocking after going to the goodwood mini track day with lsmoc, not having a runabout at the moment I decide to go have a look at it, well I started it and it ran ok, bit misfire and the exhaust seems to be blowing slightly from the centre branch, it didn't seem to be knocking till I had driven it, now it started knocking when hot, seemed to be louder when I took the rocker cap off, so with it running I went to take the rocker cover off, as soon as I loosened the rocker cover bolt the knocking stopped. so do I just fit a new thicker cover gasket and realign? it has high lift rockers from a sport 5 cooper and a very big valve head, still have a stand rocker cover but might go have a look in my garage to see if I can find a old alloy one knocking about. never had that before, thought I'd had most mini problems before lol.

It's hard to tell really as there aren't any marks in the rocker cover, I did have to shorten the push rods when fitting the head due to it being skimmed so much I couldn't get enough adjustment on the rockers rightly. the compression was quite high but I had the chambers opened out by Bill Richards who originally did the head for a 1380 to give me enough volume.

there is quite a bit of screw coming out the rocker actually, I think it might be hitting the back of the cover looking at it, funny it only seems to be once the car has warmed up though.

Well I've put the car back in the garage, it'll probably stay there for another 2 years lol. Forgot to tighten the rocker cover before driving it though so a little smokey under the bonnet opps

Need to sort out the drive shaft seals too. of all the pain in the arse jobs on a mini this needed most of them, drive shaft seals, speedo cable, manifold gasket, trying to get the electrics working and a few other minors bits. Reminds me why I stopped using it lol

Cheers I'll give it a go next time I have it out the garage.
