Just whip off the cam covers Pete and poke out the carbon. I promise you that it will be worth the hard work.

You don't. They're metal!

And lo and behold. My Jaguar engines are clean as a whistle. You remove the oil filler cap, it is clean, and you look down into a clean engine with a cam-chain, as clean as the day it came out the factory.

You open into the Rover engine, and it is like a coal truck has come past and dumped its load.

There is something seriously amiss with the breathing system on the KV6.

Oh for a 75 with a 3 liter Jaguar V6 or even a SCV8!

Thanks Vitesse.

I'm OK with the T piece bit, it''s the other pinholes & breathers referred to in Posts 5 & 6 I'm not sure about.

Cheers

probably could fit another v6 lump into the 75.
Holden had a good 3.6 litre eco tec v6 in their cars.
Only issue may be bonnet closing as i read some where Rover had to redesign the intake manifold to fit the engine under the bonnet
As a matter of interest, Kaiser, are you still doing those fine metal thermos?

kaiser · 2nd June 2019, 07:40

Yes.

As a matter of interest just had an inquiry from your neck of the woods this morning. Perth.

Done a few of these now and generally you can re-use the old gaskets but one rear gasket had seriously delaminated and bits of the black material had either fallen off or blistered. Spent more time on cleaning it off and applying new sealant than was justified in the saving of £12.99 (x2) so last time I did them I got the owner to buy two new gaskets.

was just thinking about it, i did remove a cam cover on one of my 75s a while back and remember replacing the gasket as the old one had bits of black rubbery stuff failing off.

Hi John,

Here's one of Reebs' photographs:

The two breathers, inlet and outlet with red collars, for the LH bank are shown at the bottom of the picture. The RH bank has similar but masked by the plastic manifold chamber.

The single tube at the top left of the picture is I think the vacuum take-off for the brake servo if my memory serves me correctly.

The pinholes are in the cam covers behind the connection to the narrow diameter breather tubes. To clean them properly requires removal of the cam covers. Try the LH side first, remembering afterwards to tighten the many screws in the correct order and to the correct torque.
