Morris Minor Owners Club

Hello everyone,

I am going to check/adjust the valve clearances, but as my engine has been modified, I am uncertain as to the best settings to use.

My engine is a 1098, with a 12G202 head (picture below). I have a Kent fast road cam fitted, polished ports, LCB exhaust and an HIF44 carb with a K&N air-filter.

With modern fuels (I use E5) and the above mods on an otherwise standard 1098 head, should I follow the figures for a standard car in my Haynes manual or go with something else?

Given the forecast, I'm most likely going to be doing this on a cold engine - but does that make much of a difference if engine is warm or hot?

As always, many thanks in advance for your thoughts.

Pete

Kent cams list the valve clearance as 16thou but no mention as to hot/cold? look at page 21 of the attached pdf file.

Are those roller rockers? They look very posh.

Standard later BL sintered steel rockers which have been well cleaned.
'A' Plus head studs and flanged nuts as well. Set to 50lbf ft?
Set the valve clearance to 0.016" cold.

Thank you all for your replies, very much appreciated. Will set the valve clearance to 0.016" when cold!
