Broken Timing Belt!

Hi All,

Well sh!t happened on Saturday, i was accelerating hard to join traffic when the belt broke, mechanic hasn't time to strip it down until tomorrow so I'm wondering if anyone knows if this engine is interference or not, or does it matter when your on WOT? will valves be fecked anyway or could it be ok?

Belt was done at 79k km's and there's 140k on the clock now so approx 40,000 miles, wasn't a Toyota belt as 3 years ago they were still snobs to imports, so i fitted a "Blueprint" belt i got from Fensport as they seemed to be the only ones familier with Altezza's back then....

thanks

Noel

Afraid it is interference mate, you are most likely looking at bent valves etc. I remember the hassle Am (Mr Singh) had a couple of years back when his broke :crybaby:

Gen 4 3SGE has 11:1 compression ratio so basically no space for valves out of sync.

HERE is the Mr Singh thread when his went, not happy reading.

Brace yourself Noel, fear the worst and hopefully it will be better mate.

Really sorry to hear this buddy, any news on the severity of the damage yet?

nope... still waiting for my mechanic to get it all stripped down ... no point ordering parts till he has a full list together, hopefully the pistons will be ok :(

Sorry to hear that mate, not a good thing to happen :crybaby: Maybe an excuse for a big transplant?

I just had my cambelt, waterpump, tensioners etc done a few weeks ago.. Now my car has developed an urge to randomly cut out when idling? Or when im driving along the motorway at 70mph its like it tries to stall but then keeps going coz its rolling.. its starting to annoy me, any ideas what can cause this? Im going to reset ECU later 2day and clean MAF sensor!
