Hello, I am Randall. I have reviewed your question and working on it now. Will return shortly
You are correct in that there are different chains for each side. i suspect the LH side broke or stripped. teeth on a gear. This means the pistons hit one or more valves. Engine replace is normally not required. just that head removed and the affected valves changed. No short cut from this. A cylinder leakdown test will confirm which and how many are bent. Now.. book time for the chains is 11.8 hours with removing head? 16.8 hours near 21 hours if valves are bent on other side so.. this is very expansive job as then you need the parts etc.. they probably suggest new engine as it can wind up being more cost effective to do that instead of internal repairs
I just left a message maybe with some other expert on same site. But what do you think I should do now. Sell parts on Craigslist. Car is really nice shape except engine...
tires new, battery etc... Do you think I could trade it in at med ved colorado w/ push, pull, drag ads to upgrade to another vehicle? Or should I take it in to get a diagnostic at $ 120 to give me exact price to fix?
