I recently had the head replaced by wifes uncle. When he started it up after putting it all back together it ran fine, however it was shooting antifreeze out of a pinhole in the radiator. The hole has been thier several years and never caused a problem so I figured that the old head must have been warped and that the new head increased compression. It wasnt leaking enough to cause worry so I went ahead and tried driving it home from his house. I made it about 3 miles through town at 30 mph. Then when I got onto the highway about another 2 miles I started hearing a intermittent screeching when I accelerated and the truck started losing speed. When I pulled over it had gray smoke rolling out of the tailpipe. I turned it off and checked underneath and thier was no leaks except from under the radiator, and thier was plenty of antifreeze left in the radiator and resevoir. I was able to crank it and get it started one more time. I shut it off and that was the last time it started. The temp gauge wasnt even up to norm, however the engine was to hot to even touch. And thier was steam coming from the back of the engine for a short time. It will crank, but will not start. Any ideas would be appreciated as Im already $500 into this thing I cant start throwing parts at it. The man who put the head on it looked at it and said he thought it jumped time. And is saying that it is probably the computer that caused it, but thats one heck of a coincedence if you ask me. I dont believe that the check engine light came on at any time during the trouble. Please help.

Have the guy who put the head on it do a compression check. Without seeing the truck I can only guess and here are my thoughts. When the head was replaced and the pushrods installed each cylinder that the pushrods are adjusted has to be DTC What also could have happened that the clip holding the lifter straight may have come off. You can check any noise with a mechanics stethscope or even use a piece of hose like a short piece of garden hose. Put the hose over each cylinder then listen in the other end. First thing I would do is have a compression check done.

Ok, so checked the compression and it seems fine. I think the common agreement from everyone thats looked at it is that it overheated b/c my thermostat is stuck closed. And that would explain why antifreeze was shooting out of the radiator. They also seem to think that the truck jumped time. And thats why it wont start. It will crank but wont start, its getting spark and fuel but im not sure its at the right time. And thier is suction from the intake, which makes them think that the engine hasnt seized. Do you have any thoughts on that and if thats the case how do I set the timing right?

With the antifreeze going all over check the wiring and dry them. Once anti freeze gets into something it is hard to get clean and makes bad contacts. You did reoplace the thermastat? I have seen where a engine had gotten antifreeze all over the engine and ever wiring connection had to be cleaned. They do have a product out that will get moisture out of the wiring. Wd 40 will take out moisture but there is better products on the market for the job. As far as it jumping timing first see if it will even try to fire up after cleaning the wires.
