Is It Meant To Be Blocked?
Discussion
Been trying to find the source of an oil leak but to no avail. I've replaced the rocker cover gasket but it's just too hard to see where exactly it's coming from, most annoying!
Anyway, it's my daughters 2003 plate Fiesta 1.4 petrol. There are 2 spark plug compartments each housing 2 spark plugs, the left side is clean'ish but the right side is dirty with oil. On the right side I noticed there is a hole next to one of the spark plugs, it's threaded and you can see the engine oil looking down into it.
What is this hole or required bolt called? Has it purposely been left out or has a mechanic previously not put the bolt back?
Thanks

If it's not a core plug issue, it's highly probable it's the rubber rocker cover gasket. They go hard a shrink slightly with age and barring where the front cam sprockets are they don't have any sealant on them.
Yeah I've already replaced the rocker cover seal (all be it with the cheaper branded one). A friend had recommended some Wynn's Engine Stop Leak, so I suppose thats the next easiest option to try out.The easiest solution is to get yourself a bottle of uv dye and a uv torch. The whole kit is cheap, probably under twenty quid.
Pour a small bottle of dye into the engine oil, start the engine and go around it with the uv torch. Wherever the oil leak is, you will see it glowing bright green under the uv light. The whole process takes 5 minutes and saves you hours of worrying. The small amount of dye is perfectly safe to leave in the engine until you’re changing the oil.

Here you go, £13 on amazon and you’ll be able to pinpoint the exact location of the leak

You’re welcome 😊
It is fantastic stuff, I’ve been using it in the shop for years. It makes it so easy to find the source of a leak and give the customer a quote to repair rather than messing about steam washing an engine and spending an hour looking for it. I have a bigger torch than the one in that kit, simply because I use it so often for AC repairs but I do have the same small one too and it works perfectly fine.
