Engine making horrible noise, please help!!!

Recommended Posts

Well my truck is dead. It had a good run, over 100,000 KM's since I bought it. Has 259,000 KM's or so on the clock. I am not exactly sure what is wrong, but it makes a horrible sound under idle and at RPM's after about 1.5 minutes of running from cold. A mechanic friend of my dad says it sounds like it is probably a push rod or similar. There isn't anywhere I can go work on it. If I had a place it would have to be towed cause I don't want to cause more damage. My brother drove it with this sound for about 1KM (max speed of about 50 KM/H). If I could work on it outside I would, but can't because I live in an apartment.

 

The last time I checked the injector rates was in the spring time and there is at least 4 that are starting to get bad and 1 that is close to going. And from doing some listening to it, it sounds like it is on the passenger side. And to get to the passenger side is a lot of work because of the twins piping (exhaust, etc.).

 

OK, so I took a video of the engine after it sitting outside for over a week. All is fine until 1:30 and then it goes bad. And yes I know the clamp on the air filter piece is loose, I had it off and just haven't tightened it yet. Please let me know what you think...

You need new injectors my friend. Thats the only thing that I can think of that would be instant like that. You could also hear that it was not quite fireing right when you started it.

Well my brother who has been driving it, got himself a new vehicle and I already have my Cobalt so am going to try and get rid of it. Have a meeting with the bank on Thursday to try and get the lien taken off of it, then just sell it. It has served us good, but just not worth fixing. He has a second kid on the way and I only need a truck 1-2 times a year. How much do you think I could get for it as it sits? I was hoping to ask for $5,500.

CEL is on because I had the MAF disconnected and didn't clear the code. The day after it started making the noise, I checked the codes and it had an overboost code, a transmission code and a "u"code.
