I am looking for a glow plug other than Nova. I am disapointed from the life of them.
I run in my engine about 2 litres of RB fuel 25% with about 15%oil for breaking in and i have already replaced two glow plugs. The strange is that the coil of plug is there and it has still a resistance when i measure it throught a multimeter but it can't fire up the engine.
When i put a new glow plug everything work fine for some ml of fuel and then i had the same symptoms. The glow plugs that i used was C7TF and C8TGH.
Now i run by using one RB 7 turbo CP-02 . It hasn't run a lot of fuel till now but i am afraid that it will have the same luck since RB plugs are the same with Nova's.
I found at the forum that i could try also Sirio,GRP Picco and O'Donnell.
But it wasn't clear the models of them.
So my question is what are the corespondive plugs of a Nova C8TGH? Also the colder plug from O'donnell is the 99T. Is it quite cold for a N21 7T or it is for buggy engines?
