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.

This evening I managed to remove the front subframe, bit fiddly but went ok. I'll be send that and the brace for powder coating.

Nice one fella, coming along nicely.

Finally decided to drop the block down instead of lifting it out.

By removing the roll bar (which needs powder coating anyway) I've now plenty of space to pull the block out the tranny and down. 🙂

Nice work fella. For the costs I came recommend these as an upgrade over the stock bushes.

Cheers mate. 👍

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. 

 

 

 

 

Will be following this closely!

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 🙂

[Cosmic73]

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;

 

Head now

 

[davey_83]

Bet that's a relief about the heads pal 😉

Too right, especially after seeing loads of recent posts of coolant leaking into the spark plug tubes. 🙂

[Cosmic73]

After borrowing my bosses engine lift, I finally managed to drop the block onto a dolly with mm of clearance to slide under the bumper!!

 

[davey_83]

Top stuff fella, keep it going 

[Cosmic73]

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!  🙂

[Cosmic73]

Bad news with the crank. The big end bearing has spun and it's also bent slightly. I'm getting the mains and pin journals reground to straighten back up and fit undersized bearings.

 

 

[ZMANALEX]

Plenty of cranks and rods in stock if required + every other engine part imaginable.
