Coolant Loss, Missfire on Cylinder One, Big Problems Ahead?
#21
Hey Guys,
An update, the oil looked perfect so I decided to bite the bullet and take it to my local mechanic. He was concerned about the milky stuff under the cap but he did a compression test on all the cylinders, all within 1 or 2 psi, pressurized the cooling system which lost half a PSI over a couple of hours, checked the plugs again and found nothing....so this has now turned into a mystery! He had no idea what the cause could be and suggested, that if it was his truck, he would just use some sealant and keep an eye on it. I have never been 100% sure on the sealant stuff, but he says if I follow the directions on the can exactly I won't have an issue. Anyone else use it?
Thanks again

I believe that was the evap drain for the ac. Since its been 100F here the AC is running all the time when I run the truck, I was able to get my hand in the back there and it did not smell like coolant.
The cylinder one misfire is appeared again, but tonight when it cools down Ill get my meter out and check the resistance of the coil.

For the misfire you could try checking the plug cables and see if somehow it is rotted or has melted and is arching somewhere else. The coolant, Im still putting money on a slow leak somewhere, you just have to find it which is the problem. Fill it up and drive it around for a bit to get it all warmed up then take every light you can find and go over every inch of the truck and see if anything is leaking or dripping. It may be pooling up somewhere you cant see.

Yeah, ok...

Now DexCool is the worst, but ALL radiator fluid becomes quite acidic as it ages. Fresh coolant is not corrosive, but over time it becomes so...
