Right I'v had to build a new motor for my 3dr Cosworth so I'v been getting ready
For this for some time now as we didn't no 100% wot the problem was any way my motor has a BD14 inlet cam in it and a stander ex cam so I was on the look out for a new ex cam well a Newman BD10 ex cam come on eBay at the right price so as I'v built it all up and was putting it togever I was looking at the cam the box says ex the stamping on the end says ex but it had groves which say inlet ? So I tuck it that they must just put the grove in to help with oil I turnd the motor over by hand so to make shower that all was good then it was time to turn the key and it would not start but wot fit hit me was we had compreshin coming out of the inlet manifold ?? So the time was re checked 100% right so I looked in to why things were not right so off with the rock cover and have a look at wot the cams were boing well it worked out when the motor was at TDC the ex cam was open ??? So out with the cam a we got the old cam out to see wot was going on well i will let you have a look and see wot you think













YES 2 KEY WAYS to which i only sore one when i put it togever



im so lucky as we have put the standerd cam back in and done a compreshion test and iv got away with it thank god so the phone calls will start tomorrow about this problem
