MG Midget and Sprite Technical - Oil Leak + Won't Start ??

Alright, a bit of a strange one.

Situation: 1970 midget in winter storage, starts after a bit of cranking to move it to a better shop space for some other work. Running OK for perhaps five minutes for the move. Parked overnight.

Next day, there is a puddle of engine oil under the oil pan and the car won't start despite much cranking and boosting. Usual suspects checked, gas at filter and entering carb, plugs pulled and cleaned - a bit wwet but not badly so, obvious spark at plug held near block. When cranking no oil pressure, so oil is really gone!

So could the oil loss and the failure to start be related? Could some sort of odd PVC valve problem cause some back pressure to force the oil out and then do something to the carb or induction system to throw the mixture way off?

Stumped for the moment..

So what your saying is....

1. Its a 1970 Mg midget

2. leaks oil at the oil pan

3. runs good when your just messing around

4. wont run when you NEED it to run


I dont understand what the problem is....seems pretty normal to me....LOL

Seriously, did you have spark at the plug? did you do a compression check...what where the readings....I think you said the plugs where wet....was it fuel that the plugs where wet with?

oil pressure pipe perished and allowing leaking out of the rubber section = no "visible" oil pressure and a humungeous puddle under the sump

wont start due to condensation inside dizzy cap

If this is on a A series engine with capillary oil pressure gauge
