I bought this book, and really like it. I haven’t got that far through it yet, but so far so good.

Thanks for the reply!!

Yes, I checked compression when I had the manifold off. The lowest one was 150, Highest was 215, and the rest 180-195.

Do you think it has a bad fuel pressure regulator? The old spark plugs are black, and the idle was rough. Also low on power. Today I tried unplugging the fuel pump and the compression sounded better. I took the vacuum off the top of the regulator and smelled it, it smells like gas.

If you wanted to save time sweeping, you could use a leaf blower, lol.

[quote=”kbeefy” post=140204]You let the smoke out. And the sparks.

Whats your battery voltage?

There are definitely wiring issues due to not disconnecting the battery. Start near where you saw the smoke and find the burnt wires. Hopefully just a fuseable link.[/quote]

When I took the engine out, I inspected the wiring, everything looked fine. I don’t have a multi meter, isn’t that what you use to check voltage?

[Josiah]

Yeah, that’s a little too pricey. I didn’t want to spend more than $150. Is there that much difference between the one you suggested and the autel al619?

[Josiah]

That is probably piston rings. The compression from the cylinder is leaking past the rings and causing pressure to come up through the dipstick/oil fill.

[Josiah]

Is there any other way to check the abs and srs lights other than an expensive scan tool?

[Josiah]

OK, thanks for all the suggestions. What do you think of this one?

[Josiah]

Thanks again to everyone who responded! I think I just confirmed rod knock. I took number 5 spark plug wire off and started it, and the knock was almost gone. I put it back on and started it again, and the knock was back. That confirms rod knock right?

Would it tick if it was a push rod/rocker arm problem if the spark plug wire is off?

I took a video of the car running and tried to post it here, but it would not work. I ended up uploaded it to Youtube.

Here it the link to the video: https://www.youtube.com/watch?v=2VTyIls4HtI

The car is now here, so I can check everything now. The oil looks and smells normal, same as the coolant. Yes, the oil cap is on top the valves, it looks fine and smells the same as the dipstick. I opened the radiator and the coolant around the side of the rim looked normal, but I could not see down in there because it is low. The overflow tank has always been kind of dirty and black at the bottom ever since she got it, but the coolant looks ok. Should I pull the valve covers off and make sure one of the rocker arm bolts are not torn out of the threads? I have seen a lot of complaints about the threads letting go and make a loud knock noise. Although it does sound like it is coming from the bottom of the engine. I could take short video of it running so you can hear it.

Will it shock me if I take off the spark plug wire? I guess I am a big chicken, LOL. Just don’t want to get shocked

[Josiah]

Thank you both for answering! No, the check engine light did not come on. Yes, I know some people with scan tools. I will check the oil and coolant when I get it home. The guy with the tow truck is going to tow it sometime this afternoon. I will let you know when I can. Thanks again!
