Hi Bob. Thanks for that. Very quick replay. Yes both bolts missing and one broken off. I thought about looking at the other engine i had in the garaqe and discovered those bolts. Amazing, they are not a standards size squares, but managed to get them out with a 7/16" open ender. Got the sump off in the end but I should have removed the oil pump first, which was a little awkward hanging onto the sump as well.
The block was full of black sludge. Yuck what a mess. All looks well otherwise but I am going to Plastiguage the bearings anyway. Most modern engines have about 1 thou" clearance. What should I expect with this engine?
Lots of work to be done. repair front guards. Make up new hood stays and make new hood.
I have been advised the 24" tyres are hugely expensive and have sometimes been replaced with 21". Mine has been a 4 seater, cut down into a flat deck truck, and 21" wheels fitted to the rear.
What are the prices and availability of tyres over there. 525x21 and 5.00 x 24.
PS My other automotive interest is Norton Commando's.
