Ok so some history, my car originally had slipped timing and had water get in the engine, after a few fixes it slipped again and busted some valves and camshaft, so I was able to put a new valves on it and new cam, after all this it was “fixed” the issues it had after it was fixed is it would not be…

The Aveo, IIRC, was a Daewoo marketed with the Chevy name, and being a Daewoo, was essentially a disposable car. At 10 years of age, you should probably dispose of it.

The Aveo was marketed all over the world, and wasn’t considered disposable in most places. OP, see if you can find a used engine to replace this one. I doubt that you can repair the one you have now, given the severe damage you say it has.

How is the engine oil level at this point? From what you have described I would say the entire engine was damaged from the get-go. At this point (assuming the oil level is fine) I would run a compression check. Odds are it will not be good.

A 2010 is not old, and as another poster pointed out, the Chevrolet Aveo was a decent economy car, and sold throughout the world. You did not mention how many miles your Aveo has, or if there is any rust or body damage. If the mileage is not too high, and there is no rust or body damage, it sounds…

Oil was about half full and needed a change but not bad, did a compression test, fine except before I took the test on 1 cylinder the spark plug was busted on the top, the threads where rekt so couldn’t get accurate result however compression on all other cylinders where above good.

Just shy of 100k miles, minor rust no body damage.

@oldtimer-11 basically nailed the summary of events etc… Half full of oil? Those words should induce worry not a feeling of “not bad”. Half full in that engine is most likely 2 qts… one of those qts will be up in the valve cover dripping back down into the pan as oil does… that leaves one last qu…

My guess is that when the timing went out of phase those…several times… you damaged valves. Assuming you only bent them? Replaced valves (all the valves? Any not replaced couldve been slightly bent… then failed) Also could have damaged a valve seat or two … this damaged seat probably hung one of …

What are the compression numbers? A 180 is good. A 130 sucks.

“Threads where rekt”? Hmm I bet plug electrode was damaged and threads were ok.

Do you mean the oil was halfway between Full and Add? That would mean it was down about half a quart, not half the capacity of the crankcase.

Regarding the #1 spark plug, was it broken before doing the compression test or did you break it trying to get it out for the test?
