The two bertone badges on the rear door pillars (two small phillips head screws and they pop off) and the engine cover if it isnt too rusty, but given the rest of it that's extremely unlikely..

Oh and the front and rear badges maybe.

Chur..

Ok. Im driving past on tues arvo

Did you get the rear suspension arms from the wreck ?  Always handy to have one to send away for balljoint when you've failed a WOF on that.

No spare means car immobile on hoist while you wait for the arm to return.  Been there. Would avoid if possible.

Yea I have all of that and pretty much every bit of trim/steering rack/glass/etc. just no driveline stuff.

Looks like the old fuel hose is due for replacement? I suppose 5 psi isn't going to cause much trouble.

You might be right ..

Got you a couple of bertone badges

You should modify them to read BARTONE

I was going to model them up for printing, which leaves room for shenanigans...

Glad the bottom end's fine. I read on Guy Croft's site a while ago that sometimes the turbo blocks can develop a warp that robs power, possibly due to a manufacturing defect as it seems to be random. Not sure if it affects other blocks, but if the crank spins freely it's probably not that.

What are the rings like on the pistons? Any of those caked up? I remember when I rebuilt my Triumph engine the first time I forgot to clean out the ring gaps and it was very stiff to turn in patches.

I haven't had a real good look at the pistons but everything looks basically brand new, irl it has probably only done 15k or so since I put the engine together and it is clean as inside. When I bought the engine back in the day he had assembled the bottom end already, I took the mans word that he had rebuilt it properly so didnt bother to check anything, just finished assembling it. He was an aircraft engineer at AirNZ and told me he had lightened, balanced and weight matched everything, and I can see now that he definitely had done this.

I just wish I could definitively find something causing the vibration....

[BiTurbo228]

Yeah maddening. Checked for shaft vibration on all your auxiliaries?

Reinstall the pistons and rods one at a time and turn it over to see if one of them kicks off the sticky spot?

Could it be something weird happening with one of the big ends not being true?

Yea but how does that happen? The problem is that I don't know what fuckery went on in the intervening years...

[anglia4]

Fucked if i know haha. But that test should isolate it to a cylinder or not.

[yoeddynz]

Could be a high spot on one of the bearing journals.  Put some valve grinding paste on the bearing (the fine stuff, not the course stuff) and spin the crank over with a large drill. 

Barry.

If it was a high spot on a crank journal it would show up as weird wear pattern on the bearing shells after 15k running. I was thinking about a bent rod, but the same is probably true. I’d still have a really close look at the bores and piston skirts for odd marks though.  Difficult to see what else it could be. 
 

Presume it’s not just when all pistons are mid-stroke so you’ve got maximum ring drag from all?

I am now thinking it is just ring drag, it was easier to turn at tdc. I have put the bottom end back together now and had a good look at everything while I was doing it and found nothing untoward.

[BiTurbo228]

Yeah I've got a straight plug with a copper washer in mine. The tapered one mashed the threads before it sealed and I had to helicoil it.
