A few weeks ago, I replaced the troublesome plastic thermo housing and that seemed to fix an ongoing leak....fast forward to this past weekend...

We drove a little over 100 miles to go camping pulling a pop-up camper. Made it there fine. On the way back about 5 miles from the lake, she began to overheat and the Check Gauges light came on. She got hotter than heck but I couldn't stop in the corn fields. I cranked up the heaters and limped to a bait shop about a mile down the road and shut her down. At first I began to panic. All I could tell was steam pouring from the top of the intake somewhere. Long story a little longer..Let her cool off, filled her up and drove (cool) about 3 miles to an Autozone. I tinkered some more and found that the small bypass hose under the thermo box blew up. Guess I should have replaced initially. A relief to me that it wasn't anything more serious and Autozone just happened to have the bypass hose. 30 mins later and fill up and seemed fine. Made it home with no issues.

Well, yesterday morning the wife said the battery was dead. I went out to crank it and it wasn't dead. It was locked up!!!! Starter would engage and clunk but not turn over. Not a low battery at all. Tried a few more times and she cranked up fine. That may be just a completely other issue...weak starter and a really cold front came in... Gonna keep an eye on that...but I was worried about vapor lock...

Today, the wife just got home and the wife said the Service Engine Soon light is on now... UGH!!!!

I'm going to have a code scan... Is there anything that could have gotten damaged form the overheat? I know head gaskets etc. but it doesn't seem like that. Seems to run smoothly (well just a slight hick-up here and there but she does have 140K), no loss of power and oil is fine...no milkshake...

Intake gaskets?

Sorry... just brainstorming...

Any info would be great. Have to get another 50k outta this.

Thanks in advance.

well crud! went ahead and changed the oil and definitely water in there! Not much but it's there. Guess I'll try some pour in head gasket sealer and hope for the best. Any recommendations? Bars or K & W Permanent Metallic? I just saw those online...

I know ultimately I'll need to tear it apart but maybe my luck will change and it'll seal it up...
 






found steel seal? is it worth $100? ugh...this bites!
