Hi Ian
Excellent question! Thanks very much. I’m learning a lot, now things are going less smoothly; the human condition...

Let me check.
Btw replacement bolt went in and torqued up fine, which is not proof that all is well, but is a data point.
Thanks again, Richard

Where were we? I think the borrowed throttle bodies were on, driveshafts fitted, ready to give the engine a run and try some gentle movement under the car's own steam.
So we (meaning Barry and I) gave it a run. Resulting in good news and bad news.

Good:
Starts easily, no funny noises, revs cleanly and responsively, good oil pressure, feels fine. When we dumped the oil after a few minutes running everything was nice and clean with no nasties to be found.
So the basics seem good - phew! - but doubtless lots of tweaking will be required in due course.

Bad:
Well, the day ended with more of this sort of nonsense:


....and the engine back out of the car:

You’re being tested for sure!

Clutch issues?

[Dougieboy1]

You dont have to drop the engine to apply the sticker to the fan strap - i managed to do mine on saturday with the engine still in place....

I hope it isnt anything too serious.....

Very good

In your case that also means you don't need to drop the engine on your head, which is a plus .
Hope there were no paper cuts from the sticker. Let's be careful out there.

I do have a genuine replica Swedish fan strap sticker. But one or two other things to deal with first...

Clutch issues?

Today's winner of “what’s wrong with this s*dding car now?” is... Graham. Well played sir, congratulations.

1970/71 cars seem to love clutch issues ! .. ask JohnM

The end result will be all the sweeter for the journey Richard - I hope so, anyway!

Very philosophical, Feroz.
My son’s piano teacher is a Buddhist monk. Maybe he’d like to have a go at finishing the car.

Ommmmmmmmmmmm

[inaglasshouse]

As James says, 70/71 clutches are a bit odd, and do not have the best reputation for reliability. It's a really weird mechanism whereby the inner cable stays still. When you push the pedal, the cable tries to straighten out and the outer cable sheath actuates the lever that moves the release bearing:

We'd figured out a while back that all was not well, with no drive seemingly getting from engine to driveshafts, but having got this far had hoped to investigate and fix something simple without another engine drop. No such luck.
We looked at the usual suspects for a cock-up:
- cable adjustment - not too bad
- release bearing "ears" were engaged with actuator (you have to turn the bearing through 90 degrees after mating the box with the engine)
- release bearing not sticking
etc.
No joy.
Barry and I agreed that, from the driver's seat, it felt very much like a fully-functional clutch.
Using a cheapo iPhone borescope inside the bell housing showed the release bearing working as intended. Pivot for the release arm not broken / not pulled out of case. Friction plate (looked new, as promised by the engine / gearbox builder) was present.
There even seemed to be some gears inside the box.

Hmmmm.

(There was also a sizeable oil leak from the engine, looking like probably the oil cooler, so it became a bit of a no-brainer to drop the engine again and try to sort both problems).

Some bad luck there Richard. Hopefully it's something simple. I had a problem with my clutch where the bearing wasn't seated correctly and the tension tab had snapped. Mine was an engine out again job too. Sounds like yours is engaging properly though. I assume you have 1st / 2nd gears. ?

Hi Dave,
Thanks. In my case the tension tab was good, we seemed to have gears, clutch seemed to be actuating as intended. So there was no choice other than to take it out, split engine from box, and try to figure out the problem...
Cheers, Richard.
