Yeah undo drivers side engine mount and lower engine on jack just enough to gain access.

You'll need a new crank bolt as they're stretch bolts and an angle gauge to tighten, I had a puma racing DVD manual off eBay sadly I've now lost it or I'd send you it. Iirc it was a fiver and I'd highly recommend you get one for torque settings ect.

Remember this engine doesn't use keyways so can be confusing and marking stuff won't work. If your stuck pm me and I'll try help.
