Morris Minor Owners Club

I'll let the council take care of the motorway, i need to spend a month cleaning out my engine bay. Not a job i wanted to do on a car i havent had for a week yet!

Terry, what caused the leak?

As for questions about last year's rally, sit back for a few hours and read THIS:

have a read of my first post, the oil filler cap came off

If you are saying the cap 'blew' off then there must be enormous pressure in the engine. Still suggest you take out the air filter and run without it - your performance may magically return.

I'll try it with a new filter on wednesday before i take it for a spin. the rocker cover is broken, one of the little pins that the cap twists onto is missing, weather it was there initially or not i dont know. I might not have twisted it back far enough or the cap might have been broken. The pressure gausgue was reading 85 at its peak which strikes me as ALOT of pressure. I'll change the filter before i drive the car tomorrow and see if its magically better. sounds promising though. I'll give the system a proper flush through and new clean oil and filter on friday, along with servicing it so i'll let you know what happenes.

Pressure in the engine is NOT the same as engine oil pressure ! 85 is fine with cold oil - should settle down to 60 psi when hot, 15 when idling.

After a drive today it seems to run about 90 cold at revs, 60 idle, droping to 65 when hot at revs and 45 idle. That seems much more reasnoble to me but thats with a new filter and new oil. Its still taking an absolute age for the oil to drain from the rocker when i fill it so i'll flush it through on friday and see if its any better then.
New air filter and yes, it now moves alot quicker than it did. It quite happily pulls to 40 up Brockley hill and will hold it in 4th. Still doesnt want to go over 65/70 though. Is there any way of fitting "overdrive" to the marina running gear? MGB style? or am i in cloud cuckoo land again

It quite happily pulls to 40 up Brockley hill and will hold it in 4th.

Well thats not a bad test for pulling power, maybe the engine is not set up right as regards the poor top end ? I assume you have checked the obvious things plugs, points, timing that sort of thing.

Is there any way of fitting "overdrive" to the marina running gear? MGB style? or am i in cloud cuckoo land again

Yes its possible however it involves a Marina box (1800 I think) and a Dolomite box with the Marina internals being fitted to the Dolomite box or something. We did have someone at our branch with one some time ago and it took him 3 or 4 attempts to get it right so I dont think its a simple thing to do.
