Re: Gas In Oil

I haven't taken the cap off the ebcv but I did put 12v on it and it seemed to flow pretty well, its resistance is right around where it should be.

Re: Gas In Oil

The junkyard car today had the green plugged switch connected to the "L" port, I don't know what year it was. It operated just like mine, they both leak slightly but mostly hold vacuum, I'm not sure I'd be able to tell if I wasn't using a gauged vacuum pump. Maybe they're all like that? I ...

Re: Gas In Oil

I'm checking all the emissions stuff 'while I'm in there' and have an oddball question about vac switches A&B. Being an 83 my car has the fuel cut solenoids reversed. I found this post https://tercel4wd.com/forums/viewtopic.php?t=3844#p28548 that mentioned the A&B switches might need to be r...

Re: Gas In Oil

Huh, sweet, thanks for the info! Now I remember that capacitor on the distributor is the tach noise filter, just didn't realize it went to the ECU. That FSM page says 7 volts not .7 volts, does it measure .7 volts? It looks like the signal actually comes from the ECU unless I'm reading the diagram w...

Re: Gas In Oil

I've been looking into that, I asked a question about it on a really old thread here https://tercel4wd.com/forums/viewtopic.php?f=4&t=3703&start=15#p102742. I've never measured an o2 sensor but was reading that the voltage directly off it should cycle back and forth between lean and rich som...

Re: Gas In Oil

I've read that on some carbs a leaky power valve can leak fuel when it shouldn't making it run really rich at idle but ours seems like its set up different. I tried to blow through it like the fsm says to and it checked out and didn't pass air until I pushed it in but if I suck through it it leaks a...

Re: Overheating after radiator change

To test the relay activate it with 12v, it should be open. with no voltage it should be closed. I think the wiring diagram in the fsm actually shows it backwards.

Re: Overheating after radiator change

Concerning the fan running, test the switch at a cooler temp with a multimeter to see if it failed open, no continuity, they are normally closed and activate the fan when open or when you pull the plug off. Other options would be a bad relay which operates the reverse of most relay because of the cl...

Re: Gas In Oil

It does have the o2 sensor, its possible that the EBCV isn't working right, there actually is one of those in the yard here. But what you say about it running rich not building up gas in the oil is what I've been thinking about, the plugs are sooty after idling with some smoke from the exhaust, quit...

Re: Gas In Oil

I pressure tested the needle with the float resting on it up to 16 psi and it doesn't leak at all, float appears to be new and is plastic with no fuel inside. I'll check the jets in the morning but I'm leaning back towards weak spark, I need to test it again but found a used dizzy for cheap I'm goin...

Re: Gas In Oil

I just took the top off of the carb and it looks very clean inside, like its been rebuilt. I forgot to check the site bowl while it was running but did after pumping the gas once to set the choke but it was hard to tell, like it was either pretty low or high. probably not the best time to test it. I...

Re: Gas In Oil

Could gas from the fuel pump leaking into the head seep past the valve guides and simulate a rich condition? Or up past the rings? I was running synthetic 5w 40 from winter, it didn't seem too horribly diluted but it's a bit on the thin side to begin with.

Gas In Oil

I started a thread in the general area https://goo.gl/H2BPzS to introduce myself and the car and ask a couple questions but now I have a more specific repair question... the car has been running rich which I'm trying to sort out but I just realized that I can smell gas in the oil. I already dumped t...

Re: Died on HWY, No Spark

With the cap off does the shaft spin by hand?
