Big leak...
In prep for starting up my engine soon as I finally got most of the wiring sorted I filled the engine up with oil today. As I was pouring the oil into the rocker cover, a small amount would leak from where I think was the sump near the engine mount / oil pressure switch. It would then stop leaking as soon as I stopped pouring in oil? I checked the oil pressure switch and it doesn't appear to be leaking from there but from the sump somehow. So I thought ok, I'll come back to that as it doesn't leak while standing and only when I pour oil in. I then started filling up the coolant system after making a gasket for the inlet elbow and sealing it up nice with some holymer blue. Once I got about 5 liters of water in, oil starts pouring out of the front of sump?? As I added more water, more oil came out till the point where there was oil and water coming out Any ideas how on earth water is getting from the coolant system down into the sump?? When I had the engine out of the donor, I put a new head gasket on and there's no signs of leaks on there I'm trying to now get the sump off so I can pour more water in to see where its leaking down from but the sump is now stuck and wont come off. It seems stuck towards the back but I don't remember there being any bolts right at the back of the sump by the flywheel that aren't accessable without the gearbox being off??
Please help |

Why did you put on a new HG? That would be the most likly culprit for the mixing, certainly if it's POURING.

It was seeping to one side when I bought it. Not tons but enough that I had to topup with water before I drove it home and by then it'd lost a bit. So how do I fix it?

Well drain the sump first, I think there are bolts on the back so get it dropped off and try and determine the location of the ingress.
I take it you have not drilled any holes for the carb conversion? TT

So I guess I'll need to get the engine & gearbox back out to get at the bolts between the sump and gearbox
I've only drilled one hole into the inlet manifold I made which I tapped for the temp gauge sender. This doesn't appear to be leaking. I also took the core plug out at the back of the head at the right side as you look at the engine from the front which is where I mounted the FWD thermostat. Again this doesn't appear to be leaking either. |

I know this sounds obvious and could come across as being somewhat cheeky but did you recheck the cylinder head bolts after you did the gasket
Am not taking the preverbial just a thought and I did it once so just checking |

Going back a step did you drill/tap the hole in the manifold while it was on the head? When engine was stood it would not have had antifreeze in as you were topping it up to get home, so is there any chance of frost damage from residual water in the block/head.
