Place your bets on my engine failure!!
Discussion
Slowing down in second gear today, no bad noise, just engine cut out. Tried to restart and thought the batt was dead. But recovery came and put a battery on, engine wouldn't turn at first then eventually turned over but didn't fire, turned it about three times and there was a def metallic clunk. It's a v8 developments 4.6
Will drop the sump tomorrow, and take a look at the top end.

Yeah I realise that sounded daft! Sump first, then rockers/intake manifold I guess. Annoying thing is I finally took off the pulley weight from the original 500 engine as there was a vibration, which was the right thing to do as the engine was internally balanced, makes me think that now balanced the crank has now finally given in, a bit like bending a piece of metal can be ok, but bend it back again and it may snap
They are externally balanced from the factory. But each component should be individually balanced if the engine internals have been balanced.
Well the bottom end is in one piece and turns, but locks up when cylinder 1 and 6 are at the top of their stroke. Liners feel like they are still in place, there is no swarf in the sump (nothing magnetic anyway).
When turning over, cylinder 4 and maybe 6/8 are hissing... Lost compression!?

Starter is fine, it does try to turn. I'm turning it on the pulley with a breaker bar just fine, just won't go past a full revolution. I will take the heads off I think. Can I drop the caps and re-use?
Also can I take the heads off and leave the rods and cam in place, can't quite remember the set up. Need an rv8 book!

Thanks for the help, I do feel it's valve related, I have over revved a couple of times possibly, could have bent a valve. Found the overhaul manual here

Should help!

I'm tempted to bolt it back up. I'm taking the heads to be cleaned\light refurbed. Thing is the block is in the car and I don't really know what I'm doing with checking the bearings etc, I plan a rebuild in a year or two anyway.
Someone said to me to check the small end bearing and pin etc. Thing is it only must have turned 5 times max, and it looks like a reinforced v8d bottom end (h section rods etc) and cross bolted.
