Got the balt picked up from the dealer today after a complete head replacement.....First time to drive it more than 1/8 mile Tons of pictures in my members gallery.....Couple hundred more miles of babying it, then the fun begins!

 

What happened?

 

Couple hundred miles? I got on it when I left the dealer and half assed babied it for a few hundred miles...lol

 

nice ride

 

my car looks just like yours, except mine is red

 

valve guide broke about 1/8 mile after leaving the dealer causing a valve to bend, you can see pics in my signature.......

 

^ That is just crazy

 

yeaaaaaaaaaaah, you're telling me! imagine my face when the car makes a weird noise, flashes the power reduced message and then shuts off

 

Jesus Christ! I would have a goddamn heart attack! How long did it take for the repairs?

 

jeez... if that happened to me i think i would have a cow! moooooooooo

 

I think they would have gotten me another car. Must have been built on a Monday or Friday.

 

That is really lame, sounds like someone was having fun with your car before you bought it.

Oh and dont baby it, just don't cruise at a steady rpm for very long. Getting into boost will help the rings to seat better.

 

if there were lots of these to be had wth the options i wanted and in silver...which was the low pro spoiler and side curtain airbags, i would have made them get me a new one. they replaced the entire top end of the engine so i doubt there will be any problems....and if there are i can just blame them on a crappy repair! lol

 

Your kidding right?

 

wow look at that valve lol.

 

Absolutely not.

 

He is correct, a new car with less then 500 miles needs inconsistant driving habits like going moderate speeds then slowing down etc. Ring lands on the pistons are even more extra sensative due to the fact you are using synthetic oil which doesn't help with the break in process as well as conventional motor oil. 500 - 1000 miles is a sweet spot to start screwing around more often. After that your fine.

 

break it in how you are going to drive it.


ask any performance shop.. they will tell you the same thing

 

The inconsistent rpm driving is not what I am disagreeing with, in fact I agree with it. Boost helping the rings seat is 100% false and makes no sense what so ever.

 

This is true.

If you build a new engine you do the cranking procedure without plugs to get oil to flow everywhere it is needed. You then start the engine and run it at a fixed RPM for around 15 minutes, just like when you break in a cam shaft; this will get enough hot oil everywhere to lubricate and perform the initial break in.

The engine is already "primed" and prepared for LOADED break in while driving the car. During this time you want to drive the engine under fairly heavy load and not at a fixed rpm as certain components will not get the proper amount of oil if you run the engine at too low of an RPM.

This is where some may not agree, but it is recommended by all performance shops if the proper cylinder hone was performed. Before the hone is worn off you need to run the engine hard enough to get it nice and hot and to actually seat the rings.

The above proceedure is if you have built a new engine. I know you can do it differently but this is how I've always seen it done. As a matter of fact I have seen people build a complete new engine, perform roughly the same procedure as above and hop on the dyno the same day and put down some really good numbers. Their engines are still running strong.

 

sadly.. ive been through about 3 engines with my Grand Prix... and that is what i had to do everytime (no that is not what caused the failures)

 

That valve looks like it's bent in 3-4 different places.
