Nearly forgot this one !

Just as an aside, in a previous thread, there was a discussion regarding seepage of coolant along the edge of the Head Gasket, which my Engine also suffered from, well, this time I have coated all of the β€œ Open” edges of the Gasket with a coating of Petrol Tank Sealant , that I had left over when working on my Yamaha.
It will be interesting to see if it prevents the coolant from permeating though the internal, layer of the Copper Gasket .

Hi Al,

I cross the fingers you'll have success for a non leaking engine.

The engine of my Fifteen is leaking further on. Now we - my son and me - have stopped the leakage between the gaps of the threads between the studs, the helicoils and the engine block while coating all these threads with Loctite Thread Seal. But the engine cooling is running into the camshaft chamber from the top, where the cylinderhead gasket should seal the waterways between the cylinderhead and the engine block, while the engine was not running after reassembling. This is just by hydrostatic pressure, because the top of the radiator is round about one foot over the top of the cylinderhead.

The surface of the engine block and the cylinderhead was machined in the engine shop bdfore reassembling the engine.

As I don't have another original Payen gasket we used a reproduction gasket made of a fibre kind material which don't have at all the openings these eyelet rings as the original Payen gasket.

Now, while much frustrated and without having an original cylinderhaed gasket all this work for putting off the cylinderhead again has to wait until coming back home from Scotland attending the National Rally and the anniversary celelebrations of the SP 250 at Ragley Hall.

Cheers
Rolf B.

Hi Rolf, looks like you will need to invest in an original Payen Head Gasket, the seepage on my engine was not particularly bad , but just annoying, hopefully my coating those " Open" areas of the Gasket with that sealant will prevent it happening again ,....we shall see ;) ;)

Cheers Al :D :D

Hi Chaps, just a quick update, engine being installed tomorrow morning ! !
Just realised that the Pistons that Cox & Turner have pre-fitted for me, were manufactured by JP Engineering Ltd South Australia, anybody ever had these fitted to their engines ?

Cheers Al 😊😊

Hi Rolf, just one point, I read somewhere, that it is important to ensure that when tightening down the Cylinder Head Nuts, that one starts with the centre nut nearest the Push Rod side of the Engine , this is probably due to the lack of clamping on this side of the Head .
I have just applied this method whilst Torquing down the Cyl Head retaining Nuts on my engine. ( 45Lbs Ft )

Cheers Al 😊😊😊😊

Looking good Al. One of the Lanchester 15/18s in the club has JP Pistons fitted. I believe they can be purchased through Thorntons in Shrewsbury as well as direct from Australia. all the best, Ranald

Good morning Al,

thank you for your food for thought. I've a copy of an article published June 5th, 1936 in the "The Autocar". The headline of this article is "Care and Maintenance - The Daimler Fifteen". In this article is a reproduction of "The order of tightening cylinder head nuts". And this order was our guideline for tightening the cylinder head nuts which we've tightend to 41 lbf ft. This torque figure I've found in a schedule which I've found in all the documents of the car.

Maybe the torque figure to 45 lbs ft you recommend will block the leakage but 41 lbs ft is very high, because its only a 3/8" BSF thread and 45 lbs ft. an additional 10% more of torque. Do you have an official statement of Lanchester or Daimler for the 45 lbs ft torque for cylinder head nuts?

Best regards
Rolf B.
