sounds like you already had an oil cooler spray kit

Glad it's all working and hopefully oil tight now anyway. Home straight now then?
hahahahahahah! Home straight I wish
Realistically though, the next big obstacle is making an exhaust.
With an open exhaust you can't really hear the engine and find out if you have any bad noises. I also need to let the engine get up to some kind of decent temperature to do a proper leak check of water systems.
A quick look-around last night says that the coolant system isn't circulating like it should be so that needs a rethink also.
Had what can only be desribed as a
hilarious near miss too! I'd just put some petrol in the tank and me and a few others had gathered around the engine bay to watch the system prime. We were watching the fuel filter fill up when all of a sudden fuel started squirting out of the pressure regulator, inbetween the rubber membranes, at full pressure! There was like a bloody 3 BAR petrol fountain in the garden! hahaha!
I hadn't touched the pressure reguator....can only blame the previous owners for the accident! hahaha

just kidding
So yeah, top tip, after you've checked everything - check the things you missed!
Anyway....Exhaust next, then get it run up to temperature. Finances may not allow this for a few weeks though as I'm off to France
Just gotta take it step by step!
