Rolls-Royce 20/25 Tourer engine work continues

By Chris McPheat, Jul 5 2019 05:24AM

Now that the Rolls-Royce 20hp landaulette engine has gone for cleaning and machining I have been getting back on with the 20/25. What was left of the engine was pulled out of the car and is now torn down. The photo above shows the inside of number 1 crankshaft big-end journal, from the amount of sludge I'd say it's been 30+ years since this was last looked at. The oil way for the bearing runs horizontally across the journal in this position and you can see the sludge is actually partially blocking this. I also found emulsion everywhere and the main bearings have sustained damage through running in watery oil.
