was leaking. I parked it on the lift and I'm just getting back to it <br>
now. It seems to be leaking both oil and coolant. I'm hoping that the <br>
leaks are coming from different places, but I'm not quite sure where to <br>
look. When the car was parked, I noticed some coolant seeping out (and <br>
dripping onto the car parked under the lift) but I couldn't find the <br>
source. Today, while the car was running, I saw oil dripping from the <br>
engine back plate. It looks like some oil was escaping at the fitting <br>
where the metal oil pipe that leads to the filter connects to the block <br>
- I tried to tighten it as much as possible, but it was hard to access. <br>
Oil is also dripping from the rim of the oil pan near the rear plate. <br>
Most of the oil pan rim has oil on it, with green coolant around the rim <br>
in spots as well. I don't think that the oil and coolant are mixed <br>
together - the oil dripping on the ground just looks like oil, and I <br>
didn't see any foaming or anything other than oil under the cap in the <br>
valve cover. Still, it has me worried.<br>
<br>
I watched some John Twist videos on finding leaks and he said that the <br>
sump gaskets don't leak, so maybe the oil is coming from one (or more) <br>
place and the coolant is coming from another and that's just a <br>
convenient place for them to collect<br>
<br>
I noticed some coolant around the lower radiator hose, so I tightened <br>
the clamp to see if that would help. Judging from the stain on the car <br>
under the MG, the coolant seems to be dripping from the front <br>
cross-member, but I couldn't see where it was coming from. The coolant <br>
leaked while the car was just sitting, not a huge amount but it was <br>
noticeable when it dripped onto the other car's hood. There were some <br>
oil drips hanging onto many of the engine bay components, like the bolts <br>
on the oil filter head, the starter, etc. - there was a drop on most of <br>
the lowest points of the components.<br>
<br>
Last year I pulled the engine to replace the cam and clutch, along with <br>
the other standard things to replace when doing those jobs. Because it <br>
was my first time doing engine work, it wouldn't surprise me if I <br>
screwed some of it up.<br>
<br>
I picked up some UV dye to put into the oil, but is there anything else <br>
I can do to figure out what's leaking? Thanks.<br>
