MG Jan Bul v1.0 - The Triple-M Register

From David Ewart-James

I read the article on fitting a fan to a J2 with interest, as I only use JW
2519 for short journeys around town, and overheating is always to be
feared. However, to do a proper job, I would have thought a water
pump is desirable. Has anyone published a suggestion how to fit one
or, if not, could you please print this request for suggestions?
Thanks

Dear Phil
My 1929 M-type, UV 7968, is now on the road again after a long engine
and gearbox overhaul. It still has the original crank and white-metalled
rods, although the crank is now on the limit. The rebore just scraped in
with +40tho oversize pistons. It also has had a remetalled rear main
bearing and a new front ball race. The cylinder head has had hardened
seats fitted along with new valves and guides, cam followers and
bushes, together with a new vertical drive bearing.
Ken Robinson of Slough Grinding Services took care of the head
assembly, lapping in the valves, then having set the rocker bushes in
the correct position, grinding the valves to the correct length to obtain
the correct timing and valve clearance.
When the car was running before the overhaul, the oil pressure would
reach 100psi, when starting up and dropping to about 65psi when hot.
When reassembling the engine after the rebore and head overhaul, I
found that the oil restrictor pin to the head had been built up with soft
solder along the flat section. Before reassembly I filed off the solder to
restore the pin to its correct shape. I now have 70-75psi when cold,
dropping down to about 60psi when hot, which I believe is the norm.
has anyone else experienced this bodge before? (I have seen this
bodge on a number of occasions, and always check any new engine
restrictor pin for this – Ed ).
