Need some major advice if at all possible! And please bear with me as I’m not the most knowledgeable about cars, although I can sometimes hold my own J



We own a 2002 Chevy Trailblazer with 130,000 miles on it. The car was previously owned by my mom who never missed a service appointment or an oil change and drove the car like a granny. No wrecks or problems ever and both she and my husband would completely clean the car every weekend. The car has been treated like a baby!

This past week out of nowhere my husband went to start the car for work and it was completely “dead”. Battery was fine, starter was working, fuel filter and fuel pump were fine, no visible problems or any other clues as to what was going on. It seemed like when the car would turn over there wasn’t any pressure (compression?) happening to force the engine to start.

We ended up having the car towed (!) and the mechanic who looked at it has come back with an estimate of…

$2,000 to fix the car!

I’m still waiting to receive the hard copy estimate but I’m being told that two of the valves were stuck together and are now completely bent and busted. They will have to remove the head and do quite a bit of machining for two new valves, etc…

Labor is estimated at $800, which leaves me with a $1200 tab for other parts and problems.

The mechanic is also saying that this is a pretty common occurrence in the Trailblazer.

We only owe $1800 and trade-in value (before it quit running) was only about $4600.



So my questions:

Is this estimate too high? Is it worth fixing? Would it make more sense to just put a new (rebuilt or otherwise) engine into it instead of fixing it? Has anyone else had to deal with this? Any ideas or advice at all would be awesome!

Thank you!

Not at all sure how your mechanic could have seen the bad valves, unless he claims they stuck so much that it jammed a camshaft and that broke the timing chain. I had a jammed camshaft break a timing BELT in a Volvo once, but I can't imagine a trailvoy chain breaking without it causing a lot more damage.

If that's happening a lot it's not being reported on trailvoy.

If the engine turns over OK with the starter, I just don't see it being what the mechanic claims, unless it made a LOT of noises the first time it was started after the problem began. See if you can get the mechanic to lead you through what he did to come to that precise conclusion. Don't accept hand-waving, fuzzy explanations, or "it's too technical". You wouldn't buy a $2000 television without checking with friends, so tell him his explanation is being confirmed by a few hundred trailvoy specialists.

Either get it to another mech. or get it home and do a compression check and get back to us. Also, please fill out the UserCP at the upper left part of this page. And the ignition switch is a major problem that is an easy fix.

you said it was completely dead.... but battery was fine...

does that mean that you turned the key-- and the engine DID NOT turn over- but you had lights radio etc...

or you turned the key and the engine DID NOT turn over- BUT you could hear sounds coming from the starter that was TRYING to turn a stuck engine.

or you turned the key- and the engine turned over--- but never started- just kept cranking.


Im with the guys--- howd the mechanic see that stuff inside without taking it apart.
Vent valves is not something IVe seen often on here... I dont think Ive seen it at all actually.

if you can answer the questions about the starting---- then the poster below may be right--- may be as simple as the ignition switch...
now that is something we see alot on here.

The only engine issues I have heard of is some 2002's had bad liners installed in the block and would crack causing massive engine failure. But from what I have been able to gather is that it happened fairly early on and once you get passed about 40,000 miles the probability of it happening is very low. I agree with the above that you need a second opinion and that it is a good chance that it is something electrical like the ignition switch or failed relay somewhere.

It should be illegal for mechanics to treat people like this. I have no advise for you other than I too have been a member on here for a little while and i also have a couple friends with T blazers and have NEVER heard of one bending a valve. Not to mention sticking them together? I have never heard of that happening with ANY motor ever?

I’m being told that two of the valves were stuck together and are now completely bent and busted.
sound very funny to me

It is, and with the power of the Internet consumers finally have some power of adverse publicity, and complaints to the licensing boards.

If it ends up being what we suspect, and the mechanic is a crook, I would like to see the matter pursued.

Somebody tried to cheat a member here out of only $80, and I tracked his sorry butt down to his day job, threatened to call him and/or his boss, and the money was repaid on a Sunday night.

Yea i bought an atv that dropped a valve and the piston shoved it back through the head in a different / wrong place. I bought it to rebuild and sell. It wasnt pretty. That was MAJOR damage and the valves werent stuck together. As a matter of fact the valve that fell out only had a small portion of the nail head left in the crankcase and the stem was now a permanent part of the head.

Please follow through as roadie & the guys have advised...:yes:

Get your truck back immediatley!!:worried:
from that Scam of a Mechanic. Get that truck to a better (BBB) Listed Mechanic or to a reputable GM Dealer before any work is Started...
GM Dealers, though they are pricey understand these trucks also have the means to locate issue quickly and can at least Diagnose what the
Root Cause issue is.... From that point then decide who you want to Fix-it!
Good Luck.

Are these responses a joke? You guys can't even fathom that a mechanic could diagnose a vehicle? You know that's what they do for a living, right? Even in 2009, we had endoscopes and all of that. Just because you don't know how he did his job doesn't mean he did it wrong. It means you're trying to question a man and his morals and ethics over sparse info provided by someone who obviously didn't care. They never came back. You never even had a reason to question the guys diagnosis. Who said he didn't take anything apart? How do you know what he did and didn't do?


This is exactly the kind of stuff that caused this place to turn to what it is today.... Nothing. You can't even get correct information here about most anything.
