Fantastic work, great to see another 21 being given a new lease of life
Is that an old skool alarm siren lurking in the engine bay?

yes, but redundant. Thought about removing it, but you know when you start that adventure and it wont start....4 days later...

There isnt any lockwired fasteners? Confused.

It's the tail I've highlighted in the pic. Don't leave them as straight wires, you will cut yourself up at a later date. Fold them over in a V against the exhaust

Ah I see, the lockwire on the exhaust.

Haha, that’s so true, I’ve learnt that the hard way before…best intentions and all that!…
A job for another day!…

Put the new fuses in the fan loom

Nice OEM+ mod and potentially saving this 21’s life!

Soooooooooooooooooooooo obviously as the car was nearing completion a kick in the teeth was due. It started running like crap and even dropping cylinders. I did some diagnosis and the compression test on 1&2 was waaay low






Something not right here at all and the only way to diagnose a problem like that is...



Checked a few bits and bobs and then found this, which is pretty damning. So much for the prebuilt tall engine eh.

Picture 1-4….compression results
Picture 5…..the head is off!

I would have farted around for weeks before making that sort of commitment!

No point in f'king about, I had under 2 hours until I was due to head out with the Mrs, it was challenge accepted! JUST got it done in time with 12 minutes left to shower and change lol

You wouldnt have thought would you, but the compression test and the compressed air on the bench showing the bubbles are pretty damning evidence.

I took the head to my machine shop and the sorted the valves out. Car is rebuilt now, run up, head bolts retorqued - seems much happier now!















Spotted a few things inside I didnt like very much, there was some damage on the cam journals and the wrong dowel (left) used in the block>head (right is correct). I dont know who built this engine but I think maybe they need to take a bit more care when doing it.

Took it for a short test drive - however the rear brakes had been put together wrongly and they were binding quite badly. The handbrake cable was overtensioned, the locknut was loose and the slider retaining pins were missing on the drivers side. Not good!





Pulled the dust covers off, pushed out and cleaned up the pistons and greased, wound the pistons in and reset the handbrake. Made some new pins for the sliders, dont want them falling out!









Next test drive around the block was better, small water leak which is now fixed. Brake pedal is soft as shite though so that needs looking at next.
