This evening I started removing the front subframe to realise the block can't be lowered because the steering rack is in the way, which means I'll have to lift the block up and out instead.

Not the end of the world, but just pain to set up the lift 😞

Ultimately this is the right choice. You cannot do this kind of work without taking the block out. If if you managed it you’d be making compromises you’d likely later regret.

Are these fine for road use mate, or just track?  refurbing the arbs myself but was stuck between these and Hardrace bushings.

Spot on for road use, great little upgrade over worn rubber bushes

Haha no way, I owned this car for a tiny amount of time last year, I had my supercharged 350z at the time so ended up selling it to my friend for the same price I paid for it. He unfortunately didn't own it for too long and had the new clutch installed.

Hey Alex, it's a small world, if you're around japfest next year or other club meets you'll see it again. Just gotta pull my finger out and fix it 🙂

Bit of an update, my new valve seals arrived yesterday and today I've spent rebuilding the heads. The heads passed their pressure tests and had a very light skim at Knights engineering.

The valves were minging and I had them vapor blasted.

 

Valves before;

Valves after;

I've had a very good time in the office this evening and definitely got to the root cause of the engine knock.

 

The main bearings don't look too bad considering they've done 140k miles.

I'm keeping my fingers crossed the big end bearing that caused the knock hasn't damaged the crank. I'll find that out on Thursday!  🙂
