Re: A Californian drying out in South Africa

That needle shows clear signs of wear at the base to my eyes, where it has rubbed on the jet. That's the part in use at idle, when the mixture is set. So a correct mixture at idle, compensating for the needle wear, will lead to a wrong mixture – too lean – further up the rev range. This could be the...

Re: A Californian drying out in South Africa

The earliest Imps to have the Pentastar were F-reg in the UK, so yours, Roy, is too early. F-reg ran from 1 Aug 1967 to 31 July 1968.

So don't go digging for Pentastar holes!

Re: A Californian drying out in South Africa

It makes sense to position a Mocal/Serck-type oil cooler, like yours, where air is drawn through it, as it is by the radiator fan through yours. Without air movement they don't do very much, unlike the Sport hedgehog item with its exposed radiating elements. But you knew that already.

Re: A Californian drying out in South Africa

Roy, I think you have the doughnuts fitted the wrong way round. The longer end of the bolt-tube bosses should abut the driveshaft, not be under the bolt head. The way you have it will cause the driveshaft 'spider' to dig into the doughnut under load and eventually cause it to split and fail.

Where it gets hazy is in areas such as the lower rear wing where it covers the sill. Is that structural or not?

Re: A Californian drying out in South Africa

Those Laycock pressure plates look well worth keeping. The drums are worth hanging on to as well, provided they're not scored or very rusty inside. Some of us still use drums on the front... which work very well on a small, nose-light car like an Imp, by the way.

There might be just enough room to unscrew the long stud from the engine block, and the two shorter ones of course, which might then enable you to remove the filter housing with the long stud still in its bore in the housing.

Yes, spin-on Mini (and others) filter, no non-return valve as it's not needed. With a NRV the oil pressure is slightly lower and the oil pressure warning light takes longer to go out after a cold start, as I have discovered.

Sachs, maker of excellent shock absorbers for both OE and the aftermarket, is also part of ZF whose expertise extends far beyond its famous five-speed gearboxes, some of them with first gear to the left and back. There was never a ZF five-speeder for the Imp, unfortunately.
