Thanks for the video, I wonder if you can help me. @0:54 what are those two slotted holes called what would be between the dip stick and oil filler cap? I changed my rocker cover and notice a lot of buildup in those holes. I want to hopefully clean them but can't until I know what to google. Thanks again for the video bud 👍

The slotted holes are basically the vent holes from lower crankcase taking fumes up to the rocker cover passing via these holes in the cylinder head, if there is a lot of oily gunge in these slots it's probably thick old oil from lack of previous servicing. You may want to flush the engine i.e. run the car until it's hot then drain the oil and put in fresh oil. It's a tad expensive but worth a go. If it's done a lot of miles 80k plus then consider taking the sump off and clean it out, no gasket is needed just silicone sealant. removing the sump isn't a difficult job.

I did a video on this engine recently, it's probably one of the worst designed engines ever. That pcv failing is the secondary failure the cause is often the value in the inlet manifold having failed first. Search meriva b oil leak 1.4.
