I know that the camshaft can be replaced with the engine in the car. But does it apply to all cars (MKI II and III) or are there limitations? If so, what are the problems? Peter  |

It's not possible on mk 1 and early mk 2 cars. Not sure where the cange over point is. I've done it on a 1970 mk 2 engine.

Hi Peter It is possible to change the camshaft without separating the engine /g.box on Mk11/111 engines and later Mk1 engines (so can be done in situ by cutting the inner wing behind the radiator.) This isn't possible on early Mk1 engines because -if I remember correctly - of the oil pump drive gear - sorry, I'm away from my usual location so don't have access to engine numbers or w/s manual. David I know that the camshaft can be replaced with the engine in the car. But does it apply to all cars (MKI II and III) or are there limitations? If so, what are the problems? Peter |

Hi David, It would be very interesting to know the engine numbers. I have a Morris from 1966 with the original engine and a Wolseley from 1967 with a MK2 engine. Peter |

Hi Peter
I've managed to access part of a w/s manual and it doesn't specify the engine change number - not sure if it correlates with the change to the revised camshaft profiles - there were 3 for the Mk1. I think Tony Wood is probably the most likely person to know if there isn't more info forthcoming here.

OK. Thanks. The Wolseley engine is, as far as I can tell from 1971, so it should be possible to replace this camshaft. |

Look in the parts listing - Tech Articles + Support - Documents. All sorts of change over points listed.

I have looked in the parts listing, and it seems that engines up to no. 97973 are the same. As mine is 89328, it is in the group of earlier MKI engines. So it seems I am not in luck. Thanks all for your help. Peter - |

Hi Peter
Just curious, do you have a problem with the camshaft or are you wanting to change it for a hotter one?
regards
David

The Wolseley camshaft is visibly in a bad condition. You can see that the rockers are not opening the valves equally. So it is just a question of replacing it. Though I intend to go for an MGB standard camshaft. Luckily someone has already removed the inner wing "bars" (the car has had at least three engines). The Morris shows beginning wear, but it is not critical yet. Peter |

You may need to tweak the ignition timing a bit with the MGB cam. Ideally it will probably need a little less advance at the top end and maybe a bit more at idle. Err on the side of getting the top end right if necessary. Worth double checking the valve timing as well with a timing wheel they played around with MGB cams over the years with the Woodruff key slot.
