cylinder head is OFF

[changedman]

we'll see.

personally i dont see how one cylinder losing 100lbs compression can warrant an entire engine rebuild... esp since service said $1100 worst case out the door. but i know u know alot. hmm.

 

[TheMAN]

let's think here... if the piston is cracked or the rings are ******, how are you gonna fix it? you tear down the engine!

 

[changedman]

right right- that was done, its not like im gonna have to rebuild everything. im sorry i thought u meant by rebuilding that the whole engine (all 4 cylinders) would have to be rebuilt. lol.

 

[TheMAN]

umm.. you DO have to replace all 4 pistons because of engine balance.. and its also possible that boring and honing can change the tollerances of the cylinder bore... so that further complicates things

 

[mrpopnfresh]

Aw too bad you're not in Cali. I'm NDI here on base and I could do it for free. (the dye penetrant part at least). How did you lose all that compression?

 

[changedman]

WELL
NEWS!!!

i just called them.
it DOES NOT APPEAR TO BE A PISTON OR PISTON RING.

 

[TheMAN]

burned valves?

 

[changedman]

either that or a busted valve?

 

[changedman]

i remember the tech saying he before has seen like crystalized valves?

 

[TheMAN]

I have no idea what happened, and it would be nice if you can get pics... but if this kind of s*** happened, then it probably happened a while ago when the engine ran lean... it's kind of hard to burn valves normally except when the valve lash is ****** up.... I'm glad that it's just a valve job right now

 

[changedman]

the dealer is going to take pictures (the car is 200miles away) so u think i ran lean and it took a while for it to mess the car up?

 

[changedman]

bump

If you were shooting the nitrous and running lean= bad things happen. You gotta have the right amount of nitrous and fuel.

 

[changedman]

really? running lean is bad?
:mad:
no kidding. im not some dipshit n00b

 

[MP3skaterNC]

no need to get testy, he was trying to help.

at least your in the clear for piston work, i thought it was rings for sure.

 

[changedman]

well, the dealer seems to be pretty sure since they sent the cylinder head to a machine shop.

 

[changedman]

yes, i know he was trying to help, but can people give me credit that i research something (seeing as how im a moderator and have 3000 posts?) im sorry, but its not cool for someone to be like- here is the most obvious statement- dont run lean- its not good.

 

[2k2silvermp5]

Hey pdhaudio:

done for NOW...

what IS the cylinder head exactly??

what parts are in it?

Hey man, I'm just stating that after seeing this asked by you, if your a 3000 plus post moderator wouldn't you know these things????

 

[changedman]

knowing exactly what i cylinder head is a BIT MORE detail than knowing not to run a car lean. seriously, i would expect someone to know the FUNDAMENTAL basics of a nitrous system rather than specific details of what parts are located in the cylinder head in my engine.

but ya
