So today I just found out that my engine is toast. It hasn't been taken apart yet but I think one of the mechanics mentioned a problem with the crankshaft. Symptoms are a progressively loud rattling from the engine bay on the passenger side and progressive loss of power in all gears heading to the shop. Eventually I had the car towed when I couldn't get over 20km/h, the engine can still run but barely makes power.
Also, and hopefully coincidentally, I had my car serviced the morning of the problem. They replaced the brakes, bushings, valve cover gaskets and spark plugs along with an oil change. The shop has an excellent reputation and I believe them to be honest and competent.
I have a warranty on the engine but they'll only cover up to 3 grand and the shop says this may be a 12-14 grand job.
I'm not sure if I should sell the car for parts, fix the car and sell it (it has needed everything since I bought it two years ago) or fix the car and keep it knowing everything that has been done.
It has 190,000km and is tuned to stage 1+ by cobb in Oregon. I drive it pretty rough and shift in the 4-5k rpm range.
I hope I've posted this in the right spot and greatly appreciate your feedback in this time of dire need!!
