Can you confirm that your 1-1/2 litre car is fitted with alloy connecting
rods and white metal main bearings? It is possible to fit a later crank and
steel rods, however the original main bearing arrangement must be maintained
The 1936/37 1-1/2 litre cars were supplied with a Standard 12 side-valve
engine which had white-metal main bearings where the bearing metal was run
into removable bearing holders and the assembly line-bored once the bearing
holders were fitted in place. In a similar way the (alloy) connecting rods
were re-metalled and machined to suit the crankshaft
With the 1938 OHV engine came replaceable slippers for the main and crank
bearings, while the respective diameters were increased by approximately
0.25" (main) and 0.2" crank. Not surprisingly, these changes were also made
to Standard 12, Standard 14, Triumph and Jaguar engines which were all
produced by the Standard Motor Company
I can certainly help you with some of the parts you need

Subject: [pre-xk] More 1.5L sidevalve questions
Background: This '36 SS Saloon was rebuilt by a shop in ~1980. It
only logged a few miles before being parked in a museum for 17
years - with absolutely no prep for the storage. Thus, the engine
clearly had serious rust problems. The engine has been removed
and torn down. The head is unsalvagable, but Steve Byles has
rescued me with a really decent head and gasket. Read futher…
The machine shop called today. They have taken the engine apart
and they have a few questions:
- Are the con rod big ends to be shimmed? If not, they are .006
out of round. If they are to be shimmed, then there is hope.
- What are the basic dimensions? Bore, line bore, all the bearing
sizes. With that info they will know what they are dealing with.
- One intake and one exhaust valve must be replaced. So too the
valve springs - all of them.
- Need valve guides.
- The camshaft is worn (I didn’t get specific data.)
- Need a thrust washer.
Might be other problems, but initially we need those basic
Thanks in advance!
