Oil Pan identify help please?

[canuck]

I have 2 oil pans here but no car close to me to check. 



Both are 3 main engines with 19 holes for the screws.  

Can any of you tell me which is which?
I am quite sure the flat bottom 'B' one is MGA or B and my memory tells me the angled drain plug location with the crease is Riley one-point-five.  

Thanks

In my opinion Oil pan B is an early MGB three bearing crank sump. I have never seen the other sump on any B series i have worked on in the past.

Hope this helps?

On both my Riley 1960 Mk2 and MGA 1622 engines the pans/sumps are like yours marked B. The Riley parts list shows a change from 1G2508 to 12H395 at engine no 15RB-U-H15337. Picture in parts list looks like B.
In my Haynes MGB manual there is a photo of the drain plug which appears to be in similar position to your angled one, that is at the rear offside of the pan.

Nigel & Jonathan, I thank you both for helping me out with this. 

The story behind this, (there always is right?  )  my Riley oil pan is quite bashed up and I will need/want to replace it.  In my search I have a chap with the two pans that I show. 

Why am I confused?
I have owned and worked on plethora B series engines over a great many years.
I currently own a 5 main bearing MGB, a 3 main bearing MGB, and a 3 main bearing Riley and my memory is playing tricks on me. I have seen these oil pans often but never actually noted the differences and which applies to which motor. 

I know a 5 main bearing oil pan uses 18 attach screws while the 3 main bearing oil pan uses 19 attach screws but I never paid particular attention to the shapes.  

So I will ask more about these to the chap. I  agree with you both. The angled drain plug location appears to be a 5 main bearing fit while the other, the 'B' one a  3 main bearing fit. 

Both these two oil pans  look familiar to me.   
Getting old sucks some times. 

Thanks again
Bruce

Ruby (Series II) has a side drain, and so does the motor I pulled out of a 1622 Farina.

Is the corner drain something weird (?) like Nash Metropolitan, BMC tractor, B-series diesel??

A friend has also suggested early Nissan.

I am out of the woods, thanks to all.

FWIW the corner drain plug pan is to fit 5 main engine, (think MGB) and why I have seen it often,   
The side drain pan as shown, with 19 hold up screw holes is a 3 main engine pan. 

FWIW here is why I need to swap out my one,



the whole bottom of the pan is bashed upwards as well as dents in the front. 

I got my hands on a replacement.

Salut

everytime i read this page im reminded i must change oil on my 1.5 i last did it April 21 only done 1000miles since though but still not good practise & some folk i speak to says oil deteriorates over time, i presumed oil nowadays with its chemicals added is better than it was even 20years ago even comma 20/50 is part man made

I tend to change the oil annually where I can on both the One-point-Five and Mini 850, irrespective of mileage, for peace of mind.

i would normally but its £50 for a gallon v £20/gallon of comma i think i will start doing the cheap & cheerful route each year, ive always gone with millers since using there vsp plus additive B4 shell v power & BP ulimate became so freely available so ive gone millers out of loyalty really but at £50 / gallon its getting ludicrous imo for say 700 miles / year
