96 Cavalier 2.2 automatic w/ 98,000 miles
Background: City driving only last 6 months
What happened: Driving at 25 mph and car started bogging down, like it was out of gas. Stalled when I put it nuetral. Put in 1/2 tank of premium gas, drove it home and it started backfiring into engine on acceleration. Took it to Autozone, diagnose was 106, 1 of 3. Vacum hose, throttle body intake or barameter, MAP.
What I did: Changed map sensor, checked vacum hose and tighten clamps, changed spark plugs, changed serpatine (thought it was timing belt, but I have chain), new air filter. Still running bad. Then
drove it to have someone look at it (about 1 mile) and it began making knocking AND a tickticktick noise w/ backfire. Was told it was most likely timing chain slipped and caused a valve to bend. The car is still drivable and starts right away. OK.
Called shops and was told to get a new engine or dump car. Cost of repairs for both about 2-3 grand. Looking at my book it doesn't seem that diffuclt to get to timing chain and how hard is it to replace a bent valve?
My questions: Is it really that expensive to do this job? One guy said about 5 hours labor. And is it true that I would be better off dumping the car because of bent valve. From what I've been reading it's top engine work and doesn't look that difficult to get too. Is this something my brother and I could do ourselves? Or am I too optimistic?
Thanks in advance,
