Injector Flame Traps
Where on the injector should a flame trap seat? against the injector body or on the injector nozzle? The reason why I ask is because while checking the old traps I found that 3 sat on the injector body with a gap between the trap and the nozzle, the 4th sat on the nozzle with a small gap (maybe 0.3mm) between trap and inj. body. The 4 new flame traps all measure the same and all sit on the injector nozzle and leave a gap of 0.35mm-0.50mm between trap and body. So whats correct on the body or nozzle?

What engine - would help get an idea.

Re: Injector Flame Traps
i owuld say one of your flame traps was damaged and they sit on the nozzle
Re: Injector Flame Traps
probably overtightened and crushed the hell out of the trap.
Assuming a diesel the torque is 75nm

Re: Injector Flame Traps
Sorry about the really really slow reply. Got back from Cornwall about a week ago which throw up a new potential problem.
Anyway back to the flame traps. The engine is a 1.9 AAZ with the newly refurbished injectors torqued up to 70Nm.
The nozzles protrude 0.88mm to 0.93mm from the injector body. The original flame washers have a depth measured from the outer top mating surface to the central hole between 0.79mm to 0.98mm. But, and here's the big but the new washers (6 of) from Brickwerks all measured only 0.52mm. So as you can see when torqued down all the force was only applied onto the nozzle with no evidence of the body having contacted the washer. I hope all this makes sense. So I used the old washers.
Hands up all those who have removed an injector only to see the tip of a glow plug missing
, unleashing as yet unknow damage as it makes its way to freedom.

Dont use old flame traps period.
Burned plugs - foobarrred injectors.
injector nozzles are flush to injector body

Re: Injector Flame Traps
A quick search on google images shows the nozzles protruding from the injector bodies. I can't believe that the nozzle should be the first bit to contact the washer then you torque down to 70Nm. This seems like too much pressure to put on the nozzle, surely the injector body should carry the force.
