You can see the fatigue crack on the web is much bigger - extends over half way, past the oil hole (24:23). Think it is caused by torsional vibrations due to constant high RPM. Anyone know of a torsional vibration damper for these engines? Only solution is regularly taking the crank out for crack testing. Bad luck it went so soon, but you can never be sure with an engine someone else has run.
An interesting video and I am sorry for your loss as clearly you've lost your shirt on this engine and we desperately need people to keep club racing alive. I grew up watching FF1600 at Mallory Park in the 1970's and the racing is just as close and exciting as a historic series today
What does it cost to have a engine built for you or do you do your own? Was there any damage to the transmission? Just curious, What does a car such as your cost if purchased ready to run. Thanks for the video.
+amtpdb1 Hi. Engines are between £3000-£5000. You hear of people spending £7000 on something they know is a top engine. You can get a cheap pre-90 car or early 90s car with an engine from about £6000. It won't be a winner though!
Hi I have watched you strip the engine down looking at the bearings have been incorrectly fitted And correct fitment and clearance is critical you said you couldn't do a burnout you was lucky to have a enough pressure to get you to the first bend you can't liquid test for cracks on cast iron because it is porous it was simple just hang the crank up and tappet With a hammer and if it doesn't Chaim like a bell it's cracked and if you've had a few problems look at The ports they have been Taken out fare to large And has ruined the velocity in the ports and I bet The guids are knackered In the head The valves missing the seats basically A Frankenstein Cylinder head With tolerances and building to match I bet the petrol was unleaded I bet the head hasn't got Hardened exhaust valve seats Fitted And piston ring gaps look like Never gauged checked for gap clearance And the cylinders are Smoove with no hetching finish sorry but somebody is pulling your pants down you would expect to have a strong engine but would last at least the season with a moderate freshen up without blinding you with liquid sciences and I could go on and on And of three grand it should be and five grand bullet-proof
Nothing changes eh? 25 hours maximum life on these c..p cast iron crank shafts. This was known in the seventies, handy money for engine makers, I wonder why no one has changed the rules to permit a steel crank?

Nice job! I learned quite a lot just from listing to you! Better luck with the next engine.
boom and gauges read expensive! part and parcel of racing im afraid get used to it it happens.
Hi , can i ask which Piston Wall clearance and which Conrodbearing clearance this Engine had?
Would rolling the fillets on a new crank assist your problem of crack initiation or would it be against rules?
Just curious what do you do too run gear ratios in? Do you run them in for Hewland LD200 I've never herd off anyone doing that?
Have a larger radius ground onto the edge of the journal to the journal web.......any sharp edges are stress raisers and obviously weak spots......

+Firmtec Racing Thanks
Really interesting, but can we have English subtitles please?
Whhat engine are you using?
Micossaurus Ford Kent engine or also known as Crossflow....from early Ford Escort etc
Interesting Video. Yours is the first ever FF I've seen which is also running a Staffs Box. I can never get reverse with mine, is yours the same? ;)

Sorry forgot to add oil pressure and if your missing your gears try getting the gear box dinotested

Wow that's a Endura engine
To many crank re-grounds and vibration..
