Oh! Not Marina engines again

Post by foggers »

Hello all,
Don't think I've posted here before, so a brief introduction. I have become the proud? owner of a '59 soft-top, currently fitted with a 1098. It looks like a complete heap, and it's weight decreases by the day as nature recovers more ferrous material. However, it did manage to get through its MOT with a little stitching around the rear spring hangers, and so it survives another year without being scrapped or ripped apart for a proper rebuild, for which I don't think I currently have the pre-requisites (time, money, space, skill, enthusiasm).

Now down to business before everyone turns off. The ends in the 1098 have gone. I've picked up a 1275 engine to rebuild. The oft asked questions start here:
1) I think it's an A plus. Screw on oil filter at the rear, ribbing on the block, clamp down distributor mount (rather than squeeze the body), twin exhaust downpipe. Have I got it right?

Now, what do I have to do to fit it? I is iggerant on this front.
2) Give up NOW and find a standard A Series
3) I know that I need to use a minor front plate for the engine mounts, but will that fit the A plus? Do I need to machine anything?
4) What do I have to do to the rear plate?
5) What needs to be done flywheel-wise?
6) Do I need to do anything different with the spigot bearing in the end of the crank?
7) Can I get an exhaust which will mate with the twin downpipes or manifold?
8) Or is there a different manifold/downpipe arrangement to use?
9) What should I do about the crankcase breather system?
10) And now the most difficult, (from what I've found so far), how do I identify what the engine was originally so that I can find the correct parts to refurbish it?
11) Since I'm going to all this bother, what could/should I sensibly do to improve what I've got?

Well, for a newbie, that lot is a hell of an ask. I know that bits of it have been covered before, but things I've read do not specifically answer the questions. Everything I've read about A Plus is conflicting (maybe this, maybe that). I can't even find the engine code in A series lists. 12V923EHZ. The 12 V I've found, but the rest of the coding I can't identify.

Anyway, this is just a start. I look forward with anticipation and gratitude to the flood of concise and learned information!!

Many thanks to you all in advance.

Post up a couple of pictures of the block then we can at least confirm its an A+ block although from your description it sounds like it is.
Also this recent posting has links to all the info you need.

Thank you Kevin,

Just what I needed. How come I couldn't find that page searching?? The work doesn't look too bad at all (with access to machine shop). From the photos I can identify it's an A plus. Since I don't know what year this engine is, can anyone here point me in that direction? I'm doing a complete rebuild, so nwill need shells, pistons etc, and don't know what may be year specific in that way.

Do the marina club hunt us down for nicking their engines, or am I safe to ask them??

Cheers for the link.

More questions to follow I'm sure.

Don't mean to be a killjoy but I wouldn't advocate fitting a 1275 to a 'surviving' convertible. I had a soft-top once that I was planning to uprate and the standard of rebuild compromised the handling so I waited for the next car to come along. My present convertible is a top notch build (and modified) and the difference is very noticable.
Older and more confused than I could ever imagine possible.
