I think my blazer just threw a rod.... I accelerated hard onto the freeway and heard it start making a loud clanking noise that increases with rpm. It sounds like its coming from the front drivers side.... Its an '89 but only has 85k and its in PERFECT condition! I'm really pissed now, how much does a job like this usually cost?

Thanks guys

 

yeah man that sucks, it happened to me and im having to replace my engine..

that sucks im sorry

 

Never heard of throwing a rod and not needing a replacement engine..

 

One question... can you always hear a rod at idle? When my olds threw a rod i could hear it when it was idleing, but my blazer gets REALLY loud when its reved a little, but is quiet at idle. My old man seems to think it may have sucked a valve instead. Are the two sounds similar?

 

Gotta figure it out, whatever it is before you start that motor again! Running it even for short periods of time can cause many other things to go bad.

Anyway, that does suck. An '89 with only 85k miles... Man, I'd be more worried about a lot of things on a vehicle that old with that low of miles. When it comes to older vehicles, I'd rather buy one that had 150k miles on it than one with 85k. Often, more things can go wrong from lack of use than what can wear out from use. Atleast you know the common wear items...

I do wish you luck!

I would run a compression test and possibly pull the oil pan to assess the rods.

 

Okay, so my nieghbor who is a cert. mechanic at a chevy dealer just confirmed its a rod. What are my options now?

 

My first course of action would be to drop the pan (can be problematic if 4wd...) and see which rod it is. Once you have determined which rod it is, you can pull the cap and check the crank journal. If you didn't do too much damage to the crank, you may be able to polish it up and put a set of rod bearings into it and drive it 'til it breaks. If you scored the crank, you'll need to pull the engine and either rebuild it or replace it.

 

I'm so pissed... i love this truck but dont have the money to fix it... Im crying as i type this

 

How much do you think a MINT (a true creampuff) 89' 4x4 with a blown motor would sell for?

 

It would depend alot on how it looks like rust and such since someone is going to have to drop some $$$ into it.
