oil on sparkplug nearest bulkhead.
Hi
Okay our minor hasn't been on the road much (as in at all) in 4 months (since it passed the MOT).
Now the main family car broke down, so we've turned to the trusty minor. After it sitting for 4 months we had of course got a flat battery, and slightly stuck brakes, once the battery was charged the car worked fine.
It's made 3 trips (probably a total of 20-30 miles) and all went well.
However today (I was at work so only just found out) it wouldn't start. So on looking at the spark plugs i'm told there is oil on the sparkplug nearest the bulkhead (all the other plugs are fine and dry) and I just wondered if anyone had any suggestions to how and why this oil is getting in onto the plugs.
Thanks

Could be a number of things, but most likely a head gasket if it's just gone. Could also be piston rings or very worn valve guides (probably not though).
I have started Minors though with only three cylinders firing. Are you sure it was oil?
I would clean all the plugs and try running it again, then after a trip, whip the plugs out and have another look.

I'd have also thought it unlikely about piston rings etc as it had a total rebuild 7 years ago. I'm assured it was oil and also that they've tried drying the plugs but the engine just wont start. Does that make the diagnosis of a head gasket look more likely?:)

sparkplugs are in good condition (not that old if I recall they were fitted a month or so before the MOT) and the engine doesnt start, all that happens on pulling out the starter is the starter motor trying it's best but the engine fails to start.

Compression test will tell all. But this sounds like an ignition problem to me - take the #1 lead off and connect it to a plug lying on top of the engine - then turn it over with the handle and watch for a good spark. No spark - then start tracing back down the ignition system - start with the dizzy cap and the rotor arm, then the leads to the coil and the dizzy, then the points gap. And treat it to a new set of plugs - they are only £1 each !

Aye, I'd say it sounds more like some sort of problem elsewhere in the engine; even a very very sick A series will normally start and run. Not necessarily well, but it'll normally go.
I'd start off, as BMC suggested, looking for a spark, if you've got a decent spark then check you're getting petrol...

okay i'll look into that. Like I said the plugs are quite new. But i'm sure i've got some in an engine kit if need be.
It's still strange how it was fine the other night and then the gremlins get in and next morning nothing.

well yesterday afternoon it started, and has been going fine since im told (though only a little ride round town in it). So maybe it's okay but certainly will have to check the plugs etc.
