Hello,

Just joined need some info/help. head gasket just been done on i.8 freelander all uprated parts including remote thermostat, problem we are having is exhaust is going red on tickover, timing spot on, would anyone be able to help or advise us. Thanks Rab.

Red as in very hot ??

Which part of the exhaust ?

 

[landowner]

Retarded timing, gases still burning as they exit the cylinders, timing not spot on then

 

[bobbertbear]

Its red at the manifold. Thanks Rab.

Retarded firing

This is indicative of a blocked catalytic convertor.


EDIT: or a faulty oxygen sensor

Would exhaust gases be able to heat a manifold to red heat AT IDLE ??

F1 engines get nice red exhausts at full power but a 1.8 FL at tickover ???

Must be some huge problem.........

Exhaust gases will be burning on exit from cylinder, something is retarding the ignition.
See what Freelaner says ^^

 

[teddywood1]

at that rate everything will melt ,get it seen to before you even start it up

 

[drturbo]

A very lean mixture will cause cylinders to burn hot, although I've never seen one heat the manifold like that, under power maybe...

something is retarding the ignition. Yep the owner, excellent driver but only on Sundays

Thank you for all your help, I have reset the valve timing and it has sorted the problem out. Thanks Rab.

Another happy customer, good for you mate .

Ratty had a similar problem in his 110 this cured it for a while

 

[bobbertbear]

right guys,i think i sorted it out,correct me if am wrong,but if the timing belt was wrongly tensioned,ie too tight,this would cause the timing to run out and cause my red hot manifold?

 

[jamesmartin]

it would just advance timing a little ,wouldnt do that unless you had max torque acheived on a dyno for a period of time

 

[bobbertbear]

well since i reset the tension,it doesnt get as hot an it pulls a lot better,coz even the local lr workshop couldnt find anything wrong,but when i was watching the tensioner with it running,it was way down past the wire bit that its supposed to line up with.
