hey i was talking with a few mechs telling them about my issue ive been having about my cat code (p0420)



well as ive said before i had a dealer replace my head gaskets.....well what they didnt do was send my heads off to get tested for warp or cracks, OR re-sureface the face of the head.



so im thinking to myself, they never did that and these mechs are saying well thats most likely your problem.....a warped head with a new gasket will still give you trouble as will a cracked head.



ive been putting this off due to trying to find a new job (finally found one for now) and just been thinking about it alot, such as compression loss....i have all the symptoms...(rough idle,hard starts,power loss, drop in mpg)



right now i have no cat on my car right now just to prove the dealership they are wrong and it was never my cat. (on week 6 of waiting for my headers+cat from S&S)



so i am most likely going to get a wet and dry compression test done on the car this week and if the results are as thought, i might just ditch the motor



and so i ask you guys that know, since ive seen some numbers before such as "1200", "600", "2000" for a whole new crate engine......where should i buy?



ive browsed a little saw prices between 1900-2500, i figure thats not entirely bad but i could of sworn i saw the number 1200... well if 1200 is a realistic price from somwehere, i look at it this way- if i can get new heads that are slightly better than stock for 900$, why not spend 300$ on a whole new crate engine?

if you could find one on craigslist, that might be good also.

got a good feeling ill get shafted on cragslist, if i find one saying that it runs and then shafted and find out it doesnt run...

Might as well do a 3500 swap from a G6. You'll find lower mileage motors, for like 600-800 with like 20k miles on them from junk yards.

errr..... is that a direct swap? im not familiar with the 3500 from a G6...

are you talking about the LX9 or the LZ4

the LX9. the one with out VVT. From my reading the only difference is the crank sensor. and the type of throttle body control. Which you can just use a 3400 UIM to use the LA1 TB.And I think you just swap your injectors into it so you dont have to do any computer work.

I know there are threads on here or gaownersclub.com talking about the swap.

Have you done an actual compression test on your current motor or are you just basing that conclusion on assumptions?
