I think I've resolved my noise and crank signal issues by separating the ground for my CAS to it's own location on the block. It should've been that way the whole time but, don't forget, I have no idea what I'm doing. I drove it to work the other day just because I felt like it. I was anxious about it but it did fine on the way there. After leaving work and turning onto the highway on-ramp I saw a massive cloud of smoke from the exhaust. Like Days of Thunder amounts of smoke. I pulled off and let it clear out and drove home without any issues.

It must be PCV related because when I pulled the intake off of the turbo, an obscene amount of oil came out. This caused some concern about my PCV setup. I'm running the Yoshifab catch can and crank case vent but I believe it wasn't draining well enough. I had replaced the long tube that goes down into the oil pan but I thought it might have kinked. I know a lot of engines don't even have a complete tube after they break off and float around in the oil pan for the rest of eternity. I pulled mine out and found that it had broken about halfway down the tube. I'm not sure if it was sitting in a way that caused it to back up or if my B20 oil pan has anything to do with it. I just cut the tube right below the upper flange so that any oil will just fall back down into the pan.

My one vent hose was also not completely open since it had to make kind of a hard 180 to get back to the block. I tried several configurations of angled fittings and couldn't find anything that worked well. I'm not sure that's the real cause of it but it couldn't have been helping. I was able to find a preformed Dodge hose (PN - 04694646) that worked almost too well.





I also added a second vent to the fuel pump block off plate. Unfortunately none of the local parts stores had an oil-safe 5/8" hose so I'll have to order some

I'll remember that for when I do the wiring for my CAS unit. Glad you got if figured out!

Thanks,

I ended up grounding my CAS at the thermostat housing. All other sensors use the sensor return ground at the ECU but still I have noise in my TPS and CTS signals. Approaching six months with this issue and I apparently still have not learned enough to work it out.

With so much noise in the TPS, accel enrich won't work as it should. I have at least learned that. I'm going to have another look at my main chassis grounds this weekend and see if that shows me anything.

Trying to make cars and coffee this Saturday but it ain't lookin' good.

Can you ohm the harness on the clt and tps signal lines, a tiny strand of wire will show continuity but extra resistance and a broken wire can give you funky noise.

I did have to extend my TPS wires when I switched to the Yoshifab intake. So it's definitely possible that something is weird in there.

Check the splice, or redo it anyway.

That probably wouldn't explain the noise in my coolant temp sensor though. I'll have a few days this weekend to mess with it and see what I can find.

Fixed my issues in MS (missing ground). No mountain meet for this thing though. Im on the hunt for a shortblock because this thing is done.

This engine was basically free so I took a chance on it. I'm mostly mad at myself for not rebuilding it a couple years ago when I had more money. Now we're closing on a house in a month and I have $0 for car stuff.

No matter though. I'll grab another junkyard engine and swap it in so it doesn't stay down for too long. Then I'll have a spare to build after my bank account surfaces

Not changing anything up. I can't imagine trying to start all over with a different engine I'm just going to get a shortblock and swap everything over. Then I can rebuild this one later. I'm interested to see what's going on with it. This much blowby would lead me to believe it's more than just "worn out".

Piston to bore clearance and rings, probably. That's not a thin feeler gauge below. Was about .030" at the bottom of the piston and bore

That's what I suspect. Jared beat on this thing for a few years so I knew what I was getting into. It didn't have much blowby until that day I was driving it home and it started smoking as I got onto the highway. I assumed it was PCV-related but maybe somethin' just broke . I'm going to load the wagon up for mountain meet and just not worry about it til things settle down with the new house.

Bummer to hear about the blow by. At least you can just toss another red block in there now that all the hard stuff is taken care of.

I was actually thinking about copying your catch can set up. Mine is mounted on the passenger side of the engine bay and is currently not set up to drain. It's filling up and then sucking in pure oil on hard corners with high boost. Did you ever figure out if yours was draining properly? Also, what fitting did you use to mount the catch can to the plate on the block?

I don't really have a good way to tell if it's draining but I have to assume it is. I cut the long hose off that returns to the oil pan inside the block. There's really nothing to stop any oil from draining back out. I just used an 8an coupler to get it mounted straight onto the block.

Cool, thanks. Does that coupler swivel?

Edit: never mind, I see that it does not. Thanks!

Haven't had any time or money to work on any cars lately. We bought a house in October and moved over Thanksgiving weekend. Kyle was cool enough to come drag my broken garbage to the new place where I have this neat little garage out back. Had to put up some new lights since it effectively had none. I got half of them done but there's a partition in the middle of the shop that needs to come down so I have some room to work. I hope to have some money this year for sheetrock, wiring upgrades, and tool storage.

Gonna try to get the engine back in the 142 soon so I can free up my engine stand for this other B230 shortblock.

Congrats on the new home/ purchase. Look forward to seeing the updates on the garage.

Thanks,

This is not the way to measure!!!



The top of the piston is the smallest part and never touches the cylinder wall.
This is not where the piston wears.

Pistons are not actually round
The largest part of the piston is at pin height and perpendicular to the pin.
It doesn't touch the cylinder wall either, it glides on a film of oil.
If it touches the cylinder wall bad things happen.

That garage is awesome. I wish I had a detached garage.

It's getting there. I got the partition down and three more lights up and it's as bright as I could need. Now I need some workbenches (I'll build cheap ones), cabinets (hopefully getting some secondhand), and a new toolbox.

That engine was trash. Skirt wear was the same as crown wear, chill out.

Wow, looks good and has plenty of space.
