Sounds like a broken timing belt to me! hopefully there is no damage to internal parts like pistons and valves as these engines are known to be "interference engines". Hope this helps, Bill

The 16v is a NON "interference" engine.

X2!

Both the G13 (Samurai) and G16 (Tracker/Sidekick) engines are NON-INTERFERENCE ENGINES.

While full of interesting twists and turns, changing the timing belt is not a difficult task. It takes a lot of careful disassembling and reassembly of stuff but it is not beyond the abilites of the typical shade-tree mechanic.

Follow the instructions found in various available Haynes, Chilton or downloadable FSMs and make sure that you set the distributor timing so that the rotor points to #1 cylinder with the #1 cylinder at TDC AND the #1 valves in the closed or ignition position.

No matter how you follow the cam to crank orientation procedure (the point of major confusion in setting timing), as long as you get it set so that #1 is TDC with valves closed every other revolution you'll be okay. I always position my camshaft/crank marks so they point up.

Hope that this helps!

Hey Ack: If they are both non-interference engines, (and I trust they are since you say they are) how come you see samurais and sidekicks where the belt broke and they think it might have bent a valve or something? I thought that non-interference engines would never have damage if the belt broke. Can these engines really sustain damage if the belt breaks say if you were going down the highway wide open at 70+??

Because, not everyone knows what they are talking about all the time. its your basic mind/mouth disconnect. I happens to some people more often than it does to others.

All I can say is that I have seen at least 2 engines break a timing belt and come away with no damage other than replacing the timing belt. Interestingly, the moderator of this very forum is/was the owner of one of those trucks.

I have also torn down my share of stock 1.3 and 1.6 engines and, from my observations, I believe that the pockets in the piston tops are there to prevent such damage providing that other engine component failures, modification or wear situations are not involved.

If you choose not to believe and act only on instinct, that's fine with me. I am only trying to be of help.

I have the Dayco master timing belt guide and it says the 1.6 8v is the only free-wheeling motor
the 1.3 sohc and dohc 1.6 16v and 2.0 dohc are interference motors $:-\$

If you were going slower maybe it didn't hurt anything. I wouldn't keep turning it over till you know if the belt broke or not

Anyone know it there's a roll pin on the gear for the dist drive ?

Best of luck

1.3, 1.6 and 1.6 16V are all non interference, this I know from doing
the tests myself, the 2.0 may be but I don't know that for sure.

Don't believe all you read in these books.

Not much difference in between the 1.3 and the 1.6 8v engine. Wonder why they list the 1.3 as an interference engine.

And yes there is a roll pin in the drive gear, at least in the 8v's. Don't think they would have changed it for the 16v, gotta keep the gear installed some how.

I had the belt break in lil Suzy 1.6 8v going down the hwy, no damage. Broke the belt in my Swift GT 1.3 16v idling in a parking lot, no damage. I also cranked both engines over before I realized the belt was broken. Based on this experience I would say that both these engines are non-interference. I change timing belts more often now.

Ack, Sorry that came across wrong. I was kind of shocked to here these engines are non-interference engines. I wasn't doubting you. Non-interference....That's good to know. Either way, I'll try to keep my belt changed at the recommended intervals.

That means that alot of people gave their vehicles up for scrap because of a broken timing belt, a cheap repair for the do it your selfer!!
