Disaster

Just had a call from Rogue - they have confirmed that the engine suffered from pre-cat failure.   s:cry: :cry: s:cry:   But they are unsure of the need for main cat replacement. I suggested that a new cat was recommended. Any comments?

highly recommended because if the precat has failed, little particles can block the main cat, which will for 1 will block your exhaust reducing performance and 2 if there are little bits of precat material caught up in there and they manage to find there way back towards the engine, precat failure of the engine will occur again

YES!

If you don't get a new cat, it'll remain blocked. When Toyota fixed mine, they didn't first bother to change it, though I told them to. The result was that the car just wouldn't go past 60mph and used plenty of oil.

Mentioned all this to Rogue and they still dont think it is necessary - apparently I only lost half of one pre-cat. Anyway, I have copied Patrick at Rogue into this thread so that he can see your comments. Cheers.

Sorry to hear about your troubles.

Yes, the correct repair following precat failure requires a new motor, manifold, and main cat. All three areas must be addressed. You could theoretically keep the original motor and just replace the block, pistons and bearings, etc., but the parts and labor charges quickly run off the chart.

If the main cat is not replaced, the pressure on the motor will damage the internals and the loose precat dust it now holds is likely to cause further mischief. This is why many owners (see the sticky threads at SC) who experienced precat failure wound up going through two or three motors until they finally got the right repair.

The main cat is a rather expensive part, which is why getting it replaced at this stage can be difficult. The people on the hook for the repair desperately want to save that 800 smackers - you can understand their thinking.

Guys,

It's our opinion in this instance that pre-cat material is unlikely to have contaminated the main catalytic converter. One of the pre-cats was intact, the second looked like it had been scooped out with a spoon, with the damaged portion facing the engine.

However, this is of course just an opinion. Ultimately the decision - and associated costs - lies with the customer.
