More cleaning, some replacing.
The coolant pipe on the back was very crusty. Normally I'd soak it in evaporust and then paint it, but its way too cold for that. So, replace it with a good one and I'll deal with the rusty one later.
I remembered I had a couple of genuine knock sensors tucked away for a future project, so repurposed them to this one so I can get on with it. Interestingly, these are made by Siemens whereas the aftermarket ones I've been buying are Bosch. Bank 1 sensor back in place along with the water pipe
Water pipes done on the back too.
I put the valley plate back in as well but forgot to take a photo. Cam tensioners tomorrow hopefully, or at least one of them.
