    We just lost compression in cylinder 6 after having just purchased a 2006 SRX with only 120K miles that was regularly serviced and in great condition. It was running through oil like crazy and then about 3K miles into having it started idling rough... diagnosis at the shop was 23 psi in the...
  5. ATS General Discussion Forum
    I made a post in the past like many others about needing to replace the engine in my 2013 ATS 2.0T. Since then I’ve had more issues, and after taking it to the dealership to get diagnosed they said it needs ANOTHER engine. That would make this my second engine swap. 1.I got the car from Brogan...

    So, just curious, how possible would it be to swap a Buick 3800 Series II Supercharged engine into a 2002 Cadillac Deville? Let’s say I use a Buick Park Avenue (97-05) as a donor vehicle. I’ve seen someone do it using a Pontiac Bonneville as a donor vehicle to a Seville STS. Just looking for...

    Hello everyone. I drive a Cadillac ATS 2013 AWD. I drove 66,500 miles. The engine covers began to sweat and I decided to change not only gaskets, but also chains, crankcase valves. Compression showed slight deviations and I decided to install forged pistons. It is also planned to install a cold...

    Hope y’all are well, it’s been a while but you’ve given some great advice in the so I figure I’d go to the well again...... my dear all original 71deville refuses to crank.

    So just recently my 2008 CTS DI engine locked up just a few days ago. When I was driving the car, the engine simply shut off. So I had the car towed to the dealership to find out that the car was low on oil causing the engine lock up. (Please don't blast me in the comments but no check engine...

    Howdy Cadillac gang, I have own a 1988 Eldorado with a 4.5 litre v8. The body is in great shape, but the engine is a bit tired, and I wanted to put something a bit more peppy in it. I was looking long and hard at the 200hp 4.9 and 4.5 High Technology engines from the era, but I saw that...

    I have a 1985 Fleetwood Brougham RWD with a 4.1L and a THM200-4R transmission. However, it started leaking engine coolant. After inspection, it is somewhere from the back for the engine - very possibly engine block. I am looking to replace this engine. I found a 1990 Cadillac Brougham with a...
