660XYB Engine fix

Post by Old and Slow » Sun Dec 02, 2018 10:27 pm

Sabre Six with the 2.6 straight six Zodiac engine, rebuilt approx 20 years ago by Iain Daniels for Richard Prosser.
The problem is the crankshaft rear oil seal leaking; I've tried changing just the bottom half from under the car, but without success, so it is time to lift the engine out and change both halves of the seal.
I'll replace the timing chain too, but I don't want to disturb the RM head if I don't need to.
Progress with photographs to follow; currently getting all the bits together ready to start.

Re the core plugs Philip - I don't recall seeing a set for the S6 engine, but I've collected individual plugs from auto jumbles over the years. I suggest not worrying about measuring yours - just give Kevin Dipchon at Zodiac Motors in Erith a call and he'll pop the correct sizes in the post to you and you'll know they'll fit. Unless Nigel at QRG has any in stock?

Hi Philip/Chris,
Whilst at a car show earlier this year, I was parked up next to a really fantastic Zodiac which had a RM head fitted. After talking with the owner throughout the day he gave me a business card of the place he gets all his spares from etc.
It’s a small world!

There aren't that many options for S6 engine spares, so when I rebuilt my engine I bought all the parts from Kev at ZMS. Fair prices and nice guy to deal with.

The other Zephyr/Zodiac specialist is Newford Parts Centre at Chorley, but I don't have any direct experience of using them. But they are well thought of too I think.

Hi Kev,
That's who I'm using for all my bits, but thanks for the tip.

Degrease and re-paint the block whilst the engine's out??

Hi Chris;
Great minds think alike! :)

And here's a picture of the old bottom oil seal alongside the new ones waiting to be fitted; ZMS recommend soaking in oil for 24 hours, although my Autopress Workshop Manual says not to. :shock:

If it’s a fabric (rope) or leather seal I’d soak it myself.

I'm pretty sure I soaked mine when fitted a few years ago - and it's been oil-tight (well, ish :) ) since.

Btw do you know what the original colour of the engine block was? I did mine green as I was under the impression that's how they left the factory, but I think now I was wrong and they were in fact blue. Anybody know for sure?

Mine's currently black, but that might be all the grease and grime... :)
Chris, will your engine stand bolt on when the flywheel and clutch are still in place? You seem to have bolted the plate up against the block directly, I think I'd need spacers?

The stand comes with spacer arms, but I didn't use them. I used the bellhousing fixing holes to mount the engine to the stand, but can't really recall why I didn't use the arms - possibly I didn't have long enough UNC bolts to go through them into the block?? They're 20mm square section I think. I used some thick steel plates I had kicking around, using the bellhousing bolts themselves:

I think there's room for the flywheel to stay on the engine, particularly if you use the proper spacer arms. Not sure about the clutch assembly, but you'll be removing this presumably to change the clutch?

But in any case, you'll have the flywheel off if you're taking the crank out to replace that oil seal?

Anyway, I have all the fixings which came with the stand, plus my own adapter brackets I think - you're welcome to borrow it all.

I mounted mine on the side, using the engine and dynamo mountings.
