how do you know that? whats the difference in the two ?

Uh what? So then how did I not blow up my motor when I slipped the timing chain 90* and kept running?? If it was interface, it should have been toast.

Wrong. Both are freewheeling.

Disregard anyone saying it is an interference engine.

does anyone have proof either way? ive been told both and havent seen any proof for either side

The only way you know for sure if you bent valves is to do a leakdown test. Remove the valve cover and loosen all the rocker arms so that the valves are close. Put each cylinder at top dead center and use a leak down tester to see if the cylinder is sealing. I dont know what GM states the engine is but I can tell you that I am replacing the 2.2 in my 97 next week because the timing chain jumped and the intake valves are all bent for sure. During the leakdown test you can open the throttle plate and feel the breeze Whether its rated interference or not if the timing gets that far out you will eventually smack a valve.

...in a stock 2.2 you are kinda wrong. it actually has a good bit of clearance. did your pistons have a lot of carbon on them by any chance?


No carbon. I'm pretty sure nobody went into my engine when I wasn't looking and beat the hell out of my valves with a hammer.....

Chris, Noquarter, what rpm were you turning at the time the chain broke?

At the time the chain broke on my motor, my Ex was shifting from reverse to drive and it popped and died on the spot. I replaced the chain and ran a compression check and all was fine.

My dad was driving mine when it broke so I dont know for sure but he was shifting from 4 to 3 slowing for a stop so I would guess anywhere from 2-4k rpm. I want to stress that the timing chain did not break on mine, only jumped. I dont know by how many teeth but all the rockers were still moving when spinning the engine over. Like I said, spinning any motor quick enough and change timing by breaking or jumping and pistons will meet valves. I dont know if I will tear my old motor down or not after I put the new one in but if I do Ill give you the forensic report.

2.2 is non interference, atleast in my cav its not.

i talked to a gm mechanic a few days ago and he said they are all interference..

Exactly, my ex wasn't reving the motor very high, just over idle, when the chain on mine broke. It did have 186K miles on it.

It is also possible if you have worn valve springs and/or over rev the motor, the valves can contact the pistons, putting sudden impact pressure on the chain, causing the chain to break as a result.

I realize this is a old thread but i figured this would be a good place to ask; My daughters 97 cavalier jumped time pulling a small hill.it still runs but has very little power. No popping or backfiring. I looked in the cylinders with a light and the carbon build up ( light ) is in tact , no signs of contact from valves. It had the bad rattle for a while from bad tensioner and has 220k on the engine but it ran good before jumping time. Should I take a chance on it ( $60 loss possible ) or find her another engine? She doesn't plan to keep the car much longer but I would like to get it dependable for her and whoever she winds up selling it to. Another note , I did a compression test and the numbers are down ( 55 ,47,49,52 ) but relatively even across the cylinders.

just replace the 4 piece timing set. you'll be fine

Thanks .Chain ,gears(2) & tensioner =4 piece , Correct?

New problem; no start. Cranks fine , has fire ,fuel and good compression. It is over fueling and flooding the plugs. No codes and I can still read the ecu with scanner but I suspect ecu failure. Seems I would have some cel if it is a crank/cam position sensor , wouldn't I ? Any help appreciated.

well just gonna say im at 189k on the factory chain and tensioner and when scoping the crank and cam sensors together it doesnt even show signs of being stretched its hard to tell but at 5ms i would figure the wave patterns dont lie

Problem solved< it had jumped again. Returned tensiomer and replaced the set....Runs good again.

FWIW, I talked to a machine shop guy regarding the interference/non-interference issue. He said these motors are supposed to be non-interference, but if you have the head milled very much at all, it will definitely become an interference engine quite easily. FYI.

I have a 2000 caviler that has about 160k on it. Last night I was driving home, radio was kinda loud, and all of a sudden I realized I was slowing down.
I had been traveling about 75MPH prior and when I get it the gas I wasnt going anywhere.

Well I pulled over and had some steam, coming from the motor, coolant was low, but I dont recall the temp gauge going into the red. I was worried I had blown a head gasket so I went to check the oil and steam was coming out the dipstick but I didn't see any milky substance on the stick. It also looked pretty low on oil and I saw a few small puddles where I pulled over. Well, I let it all settle down and tried to crank it and it seemed to not be turning the motor, just the starter free spinning.

I feel like a lot of problems happened at once, maybe I have a broken chain and a blown head gasket?

Any help would be awesome.

Hi, fellas, hoping i can get some assistance/guidance/etc here.
Ive got a 2002 Cavalier, 2.2 engine, about 140K miles.
Was driving and heard the notorious rocks-in-a-can sound, guessing tensioner broke, then it died a few minutes later....probably pushing about 1400 rpm.
Any thoughts on the likelihood of the valves being bent? Hoping not, as it'd be much more wallet friendly to just do the chain/tensioner 4pc set, but some places are saying they're not down to work on it cuz potential bent valves. Any thoughts would be greatly appreciated. Thanks!
