So I think I have bad rings in my 2.0.
History- 86 ranger, 2.0 carbureted 5 speed. Was my father-in-laws daily before he parked it because he got something new, or he got something new because this was giving him trouble. Im not sure. The truck sat in his driveway since 2006. I asked about it, he gave it to me, Ive been wrestling this thing ever since.

I made it run, drove it for 2 weeks but it got milkshake in the oil. Thought it was a head gasket. So I pulled the engine, re-gasketed it, prettied it up and put it back together. Drove it another week, and noticed oil all over the driveway, out of nowhere. Im okay with a few drops, but this is excessive. I noticed (and forgot) a spot in the side of the block for what appeared to be a PCV. I thought maybe this was the issue, so I plugged it. Oil everywhere. So I figured I would vent it a little until I could get a PCV. Oil everywhere. It also almost caught fire for a brief moment. My problem is I assumed it was running okay when he parked it, but that seems to never be the case, no matter what they tell you.

I drove it today, and left it running when I got it home. Here are the symptoms: Oil all over the drivers side of the engine and engine bay (I just got it all cleaned up too), fast idle, poor gas mileage (Im not sure what it should be getting, because the gas gauge doesnt work, but it is under 18 mpg for sure. Maybe power loss- its hard to tell .Im not familiar with the truck, and everyone says they are dogs. Well, this one definitely is a dog. Im sure it would go over 70 mph on a flat surface. I also pulled the hose from the valve cover and the idle dropped, and smoke came out. Not a ton, but it was noticeable.

Im guessing its the rings. That would explain the sudden appearance of all the symptoms. It probably let one or two go when I asked it to drive me to work after laying in a grave for 20 years.

ughhh..

Oil all over the place. Its even puddled in the intake. Im guessing its blowing by the valves and into the carb as well. It might even be coming back out of the intake through the carb.

It was so clean. I had it out for the gaskets. It ended up not being the head gasket, but the intake gasket that had failed. I changed them all, even the front and rear mains.

The truck when I started trying to bring it back. Its supposed to be a little run around truck. Back and forth to work and small truck jobs. I have my car I need to be working on and spending money on. Its a 2007 Charger RT, with the road and track package. I recently replaced the engine with a new crate motor, installed a cam, headers and exhaust, 6.1 intake and a torq storm superchanger. Im just a few weeks away from finishing and having it tuned. But I keep having to fix this truck.

The PCV valve on my 2.3 (and I assume on your 2.0 as well) is under the intake/behind the distributor and if it's gone then yeah you will probably have oil vapor blowing all over. I remember it being a huge pain in the ass to get it seated into the rubber boot deal that it should sit in. I would get that working and stuff before you assume the worst about rings.......sure it could have some blowby... but the rings may just be stuck from sitting and need some run time and heat cycles to come out of it.
