Not done yet.

I've spent about 10 days in hospital with a blood pressure problem, now recovering, but not fit enough to work on the elan.

Before I was ill I did succeed in lifting the cam cover off, despite no cork gasket. I had actually used blue hylomar not red hermetite so with a bit of prodding & gentle taps sideways with a mallet, the cover came free. However I did not progress it any further at that time.

I have all the oils & gaskets & a new oil pump waiting for me to get a bit fitter.

Hi Bill
Take care and get back to the Elan soon. I remember during my cancer treatment many years ago when I did not have the strength to torque up the crank main caps on an engine and that was in the days when I could normally pick up an engine block in one hand ! I was so totally pissed off I did not recognise how lucky I was to be alive.

Luckily I recovered and have had 25+ years of more engine building and Lotus driving and Elan racing and got to see my children grow up so I am lucky and hope to have many more years to go. I am sure you will be also :D

cheers
Rohan

In preparation for when I feel fitter, does anyone know if there is a particular position for the crankshaft that would enable squirting flushing oil in through the relevant hole in the top of the block (with head removed) that would be likely to back flush any crud back to the pump or sump. The attached oilways diagram shows that the crankshaft/layshaft is involved in pumping oil up to the camshafts, but it is not clear if there is a particular angle at which there would be a "straight through" pathway for oil. I've not myself done much in the way of bottom-end work so I don't know from personal experience.

I've repeated the diagram as it seems to lose detail when I edited the message text.

I don’t think the jackshaft could regulate the oil too the camshafts if there were a clear pathway.

Well i just had a French Friend phone me 2 days ago to tell him how to change an Oil Pump.
I said remove the 2 bolts between mount and Chassis on Carb side. Support Sump with Jack and a bit of wood and lower carefully. remove Oil Pump and fit new.
Yesterday he sent an Email to say thanks(merci mon amie) job done no problem.
It was on a +2 Elan.
