FG's engine leaks from the same place. I have replaced the tappet cover gasket (with a proper cork string one) and I have replaced the replacement "U" type fuel pump with with the original "T" type, now that it has been overhauled with new valves and diaphragm and the leak is still there! To be fair, I have long suspected that it is the block to crankcase gasket, as there is a similar, but lesser leak on the off side front of the engine adjacent to the dynamo.
However, as the engine makes no funny noises (well no funny noises considering it is an Austin Seven!), goes well and blows no blue smoke, I am inclined to leave well alone. The oil consumption is about 1500 mpg which is in line with what the factory said it should use (should leak?).
Given the problems experienced by Reckless Rat, I have refrained from trying to tighten the block to crankcase nuts!
My engine is of the type that is bolted firmly to the chassis and i suspect that a lot of the problem is that the crankcase flexes slightly as it tries to stiffen the front of the chassis, but I have known four Sevens well during my time on this earth, my first RP saloon, my special, a friend's 1935 ARQ Ruby( which he had bought new from Thomas Startins in Aston) and FG, all of which leaked oil at the nearside rear of the crankcase, I am inclined to think that it is a characteristic of the cars
Mind you, I am of the school of thought that says:- "If it ain't broke, don't fix it!" so I shall live with the oil leaks until the engine has to come apart for overhaul. Thus I shall continue to wipe the oil away at the end of each day the car goes out. Rag is cheap and I get my oil (a good quality semi-synthetic 10W/40) from work for nowt so perhaps I am biased.
