has anyone ever had problems with crank, rods, pistons? or moters blowing up? with a stock ls (94)

 

To answer that question, Yes. People have had various mechanical failures for hundreds of different reasons.

 

have you had a moter blow up?

 

a few actually.

 

what caused it?

 

my moter seemes to be rougher than before

 

rougher?? I don't know what that means.

dirt, dust and sand inside my engine is what killed it.

 

sorry mispelled, i was trying to say more vibration! (i've been up for a long time kinda buzzin!!

last tune up? oil-change?, is your timing ok?, how are your engine mounts looking? ive had the same ls engine for 2 years i got it at 127k miles and its now got 172k miles and all of those miles ive redlined numerous times a day, the only problem that engine had was the person before me burned 2 exhaust valves in cylider 3 and the machine shop he got the work done at used the old valve seals and also hot-tanked the head, so all the seal were toast. the engine smoked(blue)alot at idle and start up. i fixed the seals and no problems since....other than the normal aged engine problems(a knock here and there)

 

tune up was done before i got the car, there is 110 thousand on it now, the moter doesn't smoke, i use castrol syntec 10w30,,,,the engine just feels like it isn't very smoth!? i don't know maybe i am just crazy!! haha

recent valve adjustment done? not having the valve clearances in spec can cause the engine to be rough.

 

I hade the vales checked about 5,000 miles ago this just started today

yea check your cat out, i had a clogged cat and it made a world of difference once it was off....no more rough idle...no nothing...lol well before you go and replace the cat, try and run seafoam through the engine and see if that helps

 

hey I will try that foam stuff you were talking about! I am going to replace my cat to it is clogged up I think!
