30 Year Old Donor Race Engine

We bought an engine for the block and crankshaft which are the main parts destroyed in the Anglesey engine blow up.  It was sold as a low mileage engine that has sat in a garage for 30 years.  It was never going to be good.

In the video the engine gets dismantled to see what leaving an engine for so long does to it and it’s not pretty!  The valves in the head have rusted in to place and the engine had filled with silt and rust.  Good job we only need the crank and block which will have liners fitted.

ELM327 clone teardown/review

ODB2 Scan
ODB2 Scanner

The Fiesta, I unaffectionately mentioned in the engine blow up video, had the check engine light on (this happened before we put the dirty fuel in by the way!).  For £6 I decided it’s well worth giving one of these ELM327 ODB-2 scanner clones you get on eBay a go.

In the video there is a little teardown to see how they can make and sell it for just £6.  We find a surprisingly expensive chipset from Microchip (PIC18F and Microchip’s CANBus controller).  They could be fake parts as I’m sure there is big demand for these in China which would keep the cost down.  However, I suspect the reason they used these chips is because the stolen or open source firmware was written for the PIC18 and they didn’t have the skills to re-write it for a lower cost chip.  It also explains the use of a crystal oscillator!
