    2004 Cadillac CTS 3.6 liter - 192,000 miles and still strong!

    My daily commute is 220 miles (110 miles each way) and have made this commute nearly every day since I bought my 2004 CTS in 2006.

    I adore this car, and wouldn't think of replacing it. The only problem I have had with the car was a set of tie rod ends and a drive shaft last February.

    I'm starting to worry about the internals though. I am hearing some slop in the timing chains(?) and its using a LOT of oil. I am thinking of replacing the engine (and tranny?), but haven't been able to find where I can buy a good overhauled engine.

    Any suggestions?

    3.6 liter VIN "7"

    Thanks MUCH, in advance!

    Dave

    192k, wow. Here is a LY7 for $3,000:

    Why not just rebuild the one you have? Port and polish the heads, tune it, etc etc.

    Thanks for the reply. Frankly, I don't have the time. I would love to do that with my sons as my dad did with me when I was a kid. I have very fond memories rebuilding the engine for my Ford Falcon. Good times indeed.

    I did find one place that would rebuild mine with a 7 day turnaround time... www.remanufactured.com. $4,490.00. Anyone have any experience with these folks?

    Anyway, thanks for the reply.

    Dave

    Sorry... The quote to overhaul my long block was $3,490... Not $4,490...

    $4,500 seemed a little steep. But that company just brings it back to original specs, right? For $3,500 I think you could probably take it to any automotive machinist and have new piston rings put on, hone the cylinders, shave the heads to up the compression from 10:1 to 11:1 (like the LFX), port/polish the heads, port match the intake and exhaust to the heads... yeah... thats about $3,000 worth of work. Spend the $500 you save on a ECM/PCM tune, like that from Trifecta.
