    Update: took a look at all brakes. They look fine and still have plenty of life. Replaced vaccum lines for EGR, PCV, and MAP sensor. Replaced MAP sensor as the voltage for it was a bit low. Everything works much better now. Still has a but of a rough idle, but not nearly as bad as before. Goes on the highway just fine now.

    nice good to see you got it working better. A rough idle is not out or the norm for a escort with a cfi motor. Have you checked timming by chance ?

    also if your looking a bit of more power out of the motor a roller camshaft from a HO with the HO roller lifters and springs with the HO header will give you a little more power.

    Correct. It's likely that this particular vacuum line is intentionally missing because the heat riser (vacuum motor itself) is also leaking vacuum, and needs to be replaced.

    Checked timing today. It looks okay. The car is working mostly as it should. There is another problem that has risen. The PCV thing (it looks like a PCV but it isnt) is throwing a bunch of oil into my airbox and some of it leaks out of it onto the exhaust headers. Any solution to this? Yes, I will be doing a compression test but it will have to be after Labor Day.

    Edit: the car no longer runs hot and handles highways and hills just fine now. Really nice drive actually. I have a 2014 Golf R that has been my daily but now that the Esort is mostly good, I'm hoping to use it for general use and my Golf for autocross which I've been getting into more.

    There should be a filter on the PVC thing your talking about.

    I see. Looks like it blew off. I guess thats what keeps the oil out?

    It keeps most of it out. Some will make it though however.

    The part is called a crankcase breather element or filter and they are rather cheep. I seen them on eBay for as low as 2$ for off band ones.

    There seems to be quite a bit of it making its way out still. Compression is slightly less than ideal on the number 3 cylinder, but not enough to make much of a concern about it. Going to take a look at the crankcase ventilation valve that the vaccum for the breather connects to.

    Hopefully you can find the problem. if it ends up not being a simple fix a catch can could be a temp fix.

    I know this might sound dumb but have you ever seafoamed it? (Youtube if need be) Just keep the rpm up and slowly pour 1/3 of the can into the brake booster vac line. Turn off engine Let it sit for a few min then start it up and rev 2500-3000rpm. For me, this helps clear up the idle it’s worked on my 89 F150 my 84 mustang, 04 SvtF. Just a thought for that rough idle
