I do smell gas when i check the spark plugs but i replaced the o ring in the injectors like a week ago

I checked all spark plugs i did smell gas but i replaced i injector o rings about a weeks ago. And when i had it running i pulled spark plug wire on spark plug wire 1 there was no change on 2 3 and 4 when i unpluged the wires the car was wanting to die. And The motor still shakes at low idle.

I want to help, but it's really hard to figure out what you are saying. At least put some periods in there every once in a while. Just saying.
Sounds like your car might be running on 3 cylinders. You should make sure there is no flooding of the cylinder.

How do i cheack if theres flooding in the cylinders? And its only runing on 2 cylinders ima try to do a compression test today

Manie 01-15-2018 10:36 AM

Compression was 85,70,75,80

That's very low. To be clear, you should check compression as follows:

Make sure your battery is charged, and use any other starting assist device you can.
Remove all plugs (unplug coil, if you love it)
Install tester firmly/tightly onto cylinder to be tested
Crank and count ten compression strokes
make sure gage isn't dropping pressure (loose valve core in compression tester check valve), and record reading, repeat on remaining 3 cylinders.

If that looks like what you did, try it again, with a cap full of motor oil down each cylinder. If it jumps up dramatically, it's probably rings/rebuild time. But either way, it's probably that time.

That said, this is what these motors do. If you want to drive it, it's probably not about to disintegrate by any degree, you could drive it plenty while getting together another motor or overhaul plans/research for this one. Your rings are burnt up and will let lots of blowby, you'll have a smoky pos and will have to add lots of oil, but if you want to drive it go put a full change of 20w-50 with a quart of lucas, check it often, and keep pourin' it in... thickest cheapest stuff you can find, 20w-50 is in spec for a new KA (over like 55f or something), so considerably thickened from that won't do much harm in your motor, with it's excessive clearances. Obviously you will have to further isolate the miss to spark or fuel on cyl 1, and fix that.

Also, it'll leak really badly, because the blowby will overpower your old clogged pcv and push oil past all the seals when the crankcase pressurizes.

When you injector 0-rings went bad my 240 shook like crazy. I replaced the injectors and a few days later is started again. The o-ring got ripped some how. So this time I only replaced just the O-rings. I took the fuel rail off but installed everything else and primed the system to see if any injector was leaking. Its nice to see the bottom of the rail to see if they are leaking

I replaced fuel injectors with new ones and fuel filter it fixed the problem but now when the engine gets to running temp so much white smoke comes from the exhaust and engine where the headers are at. Any idea what this could be?

lunchmeat 03-08-2018 02:20 PM

Spill something on the headers? Does it smell sweet?

It smells like a burning

apex128 03-08-2018 02:42 PM

You probably have a header leak and leaky o rings. Did you lubricate the seals when you put the injectors in?

Ya i luped the o rings before installing.

apex128 03-08-2018 06:51 PM

They probably still broke somehow. I would check them to be sure. The smoke from the engine bay is just an exhaust leak that you need to fix.

Manie 03-09-2018 09:52 AM

Would the piston rings make it smoke like it does? Somone told me to take out the plugs and pour marvel mistery oil into each cylinder and let it sit for a couple days

apex128 03-26-2018 07:59 PM

What does the smoke smell like? "smells like a burning" is not exactly a good description.. Your compression numbers were super low, so it could be bad rings. I would do what mechanicalmoron said and report back.

Manie 03-30-2018 09:21 AM

The 240 runs it still smokes a lil bit but not as bad. Theres oil coming out the exhaust. And also where would be a good place to order the power window amp?

Just drive it until it blows up.
