Strange V8 Engine No.

Hi all,

I've recently had a "new" V8 fitted to my SIII 109 after the oil pump failed on the last one and I'm trying to identify it from the engine number. I have spent hours looking at all the lists on numerous web pages but the number I see on the engine has a "C" suffix which doesn't seem to be one of the options.

My engine number is in the format 25DxxxxxC which fits perfectly with the information I have that it is from a 1988ish EFi Rangey with an auto box. My problem is the "C" suffix. Looking at all the lists, where there is an optional suffix it is listed as xxxxxA,B,C or xxxxxA/B so if mine fits in the correct place surely the list would show this? It's very difficult to see the actual engine number and the best I can do with the last character is either a "C" or a "6", either way it is definitely not an "A".

I'm wondering if the "C" represents something like it being a factory reconditioned unit but if so I'm surprised that this isn't mentioned on the lists purporting to be "all engine numbers". Any clues?

The first thing I want to do is fit an oil pressure gauge and I need to know if it already has a suitable sender or if I need to fit an aftermarket one. Does anyone know this off the top of their head? I see that on many of the exploded diagrams there is a different setup for engine numbers with a "B" suffix which I'm assuming mine doesn't have a sender suitable for a pressure gauge, only a light. If so, is it possible to swap the existing one for the necessary item?

Sorry, lots of questions and this is only the start, but I'll try to make sure I search thoroughly before wasting your time.

Thanks in advance for any help

Re sender, the light type sender is a lot smaller than the pressure type one
IIRC you need a t piece to fit a guage on the earlier type engine as they only had a switch and you need both
the guage type is about 40mm in dia and is like a small can . HTSH

Thanks tacr2man, much appreciated

Engine no 25D00001- Suffix B,C 9.35cr Auto Efi(Lucas) Approx Date Oct85-Oct89Is this any use?

whats down in the hole on the side of the pump at the moment , if its got only one hole it was the light type and you will need to get a t piece. as you need to keep the light to get the efi to work IIRC

Thanks groenendael, does the suffix only specify the different EFi system then? Any ideas why this isn't listed on all the websites I found?

Cheers

I'll check out the actual setup at the weekend tacr2man. I've junked the EFi in favour of the carbs of my last v8 that lunched itself so this could be the simplest answer.

Thanks again
