Hello there. Sorry for some of the inexperience, or obvious questions I present. Air filter? Is stock now, I had removed it thinking more air was better, now it is back on and the engine is happy. Thermostat? I reinstalled a failsafe on a no stat system.

I found out why the stat was out. My head gasket was garbage.

The truck (it is an S10 and someone else has it registered so its anything from a 1991 to a 1994) is in the shop getting its head gasket changed, as we speak. The mechanic said he will flush radiator, and indicated frustration with the design of how the engine is in there. The radiator from a van went unnoticed, but lo and behold, it is still doing its thing.

I feel the proper gasket will not make the milkshake oil, thanks to my oil-to-coolant gasket failure, every time I replace the 15psi radiator cap. Was inclined to ask about 4psi and 7psi units for a GM. But hey, free truck, so, I have never been enjoying vehicles more in my life.

I'm driving an F-150 at this time.

Not sure some of the insults or suggestions being hurled around here, but I want no parts of it. This F150 is my loaner until I get the S10 out of hoc. Will set me back $450.

I have reviewed some of the comments and I can't relate to what is being said. The F150 has put on about 600 miles in the ast few days, and is on track to break 1000 today. Too busy to check in, I work. Nice ride. Just continue the spirit of the forum, grab a beer,

Getting ready to hit the road. Peace out yall! Will check in when I can, I am on the path of least resistance.

Again, sorry to leave you all, I have the update of springing for the appropriate repair, but I must get going, and thank you all for your assistance. I almost bought a 1988 Trans Am with a crank no start condition.. someone beat me to it. Will post up on which is next.
 
uh what was the question again? or was this just a general informative rant that's supposed to make no sense?

you also reference some posts Maybe put links in so it makes more sense?
 
Heh, a misfire of a post?

Alright, I can summarize. The truck I referenced in the thread I asked questions about sealers in, is presently getting its head gasket replaced, radiator flushed, and this is the appropriate repair instead of putting in every sealer on the shelf.

And I am driving an F150.

Head gaskets aren't too bad on the 2.2 4 cyl in these, but if you have the 4.3 V6 it might take all a gear head's tools to set this right. IDK about the 2.5 iron duke. The emissions sticker under the hood will tell you the year for sure.

The shop is doing it. Any shortcuts they may take?

This one is costing $450.

Yeah but they won't tell you.

Good news is I think you found a good shop and the car is so old they've worked on a million of them already.

I've never heard of a GM 2.5 having a head gasket failure either. Iron block and an iron head pretty much made that impossible!

In the early years John deer built some of the 2.5 and they all had head cracking issues. They're all gone by now though. Just a little food for thought . Useless info

I just got a text back from the mechanic doing the head gasket job, working out of an Aamco, I sense a side job, nothing wrong with that. The head is off of the engine. He texts the following: I couldnt get the truck to start, pushed it in (to the shop bay.) Rear two cylinders were toast. Might be locked up. I sprayed it with oil and I will check it out around lunch. So, apparently it was doing either the "start and die," or just wouldnt fire for him. It started for me though but hey it is what it is.

The last it ran, it had a muted muffled sound to it, with lack of power but also in intermittent spurts. I drove it there with the oil low (3 quarts) to see if it would milkshake it or not. The mechanic had asked me if it was strawberry milkshake or chocolate, I suppose to ascertain if it was mixing with transmission fluid or oil. It did not mix on the way. Ran hot, yes, but this is the first I have heard of cylinders locking up. However, this explains the lack of power.

What oil do you think he sprayed those two cylinders with? Is he referring to letting them soak?

I also am glad it got mechanical attention. I think it can be brought back from the brink, however, has anyone ever worked on an engine that had some of these issues?

He did not say anything about broken cranks or other things, just that "rear two cylinders were toast" so what could that mean, in more technical terms?
 
Locked up would indicate the rings or maybe pistons are seized to the cylinder wall... Aluminum pistons can and do melt at extremely high temps(friend has a 'Yota in his shop replacing engine due to overheating and a partially melted piston because of head gasket failure)... If it spins over but doesn't start, the engine isn't seized but still the rings could have gone limp from the heat and now doesn't have enough compression to start...

With the info provided, it's impossible to know the exact engine condition...
 
I just got a text back, he says the two cylinders are still stuck. Mechanic suggests letting it sit overnight and hopefully will free up. Says he poured seafoam and oil in the cylinders.

Any suggestions about what else to try? Apparently two cylinders are locked up? Maybe thats why it wouldnt start for him this morning?

How about paint thinner, laquer thinner, and acetone? Or, I may be able to post pics of how bad the cylinders are this afternoon, looking down into the block?

That means the engine is seized, simple as that. Even if your mechanic manages to free the cylinders, chances are that they will not have compression.
