Are you sure it just isn't the support bracket for the front pipe/pre cats which is broken?
BTW, I posted a few weeks ago that my brother in law's CF3 156 ran it's big end bearings whilst I was driving rather briskly. Finally, after investigation, it is only no.3 big end shells which have disintegrated- no damage to the crank pins
(It's always seems to be no.3 which goes first as they run directly above and close to the exhaust pipe. I think, from memory, no.2&3 big end bearings are both oil fed from no.3 main bearing.)
As the car also needs some exhaust parts, does anyone have experience of fitting a performance manifold and is a lot of ground clearance needed to fit it?
(Are axle stands ok?)
Ideally, we'll go for the full manifold. The cheapest I can find is the Supersprint
from Motorsport World at £482 inc vat
, or the CSC
one from EB Spares at £452.38 + carriage
Failing that, the Supersprint
catless front pipe option which retains the manifold is £341 inc vat.
This is cheaper than the £385+vat (£452.38)
for the standard pre-cat section from EB Spares, and certainly more expensive then the £261 inc vat
from cats 4 less. However, I wouldn't go with the cats 4 less option. I know what these cheapo cats are like and I know the issues there can often be fitting them. If someone else is doing it, and you don't mind loosiing a few horses, then fine, but not for me.
After a thorough check, for emissions purposes, I don't think it matters which cat(s) are lost. The pre-cats should heat up quicker than the main cat but I think they are likely to be as efficient at keeping emissions down. Only if all the cats go should there be an MOT problem.
Also, as long as the lambda sensors are good, there should
be no issues with engine management lights coming on. The front lambdas are before the pre-cats, and the rear sensor is after the main cat. I think if a management light comes on (after loosing either pre-cats or main cat) it probably indicates a slow switching lambda sensor in the pre-cat section.
