Prechamber Mod "Flame" Front
I installed the moded PCs and a late model cam yesterday and had a set back, I was torquing the last injector and herd a POP and the injector turned easy.
I lowered the seat 2 mm lower than MB specked and that is where the upper half threads start so there was very little material left, and when I torqued the injector, the PC lower half broke away from the upper half.
SO... I cleaned up the ones I pulled out, reamed the burn holes to .136 dia, and only opened up the seat dia, did not lower it, ( the 1.5mm was not worth the time and seeing how the PC is made, I feel better with it thicker).
Reinstalled them this morning. It starts easer, had to lower the idel a touch, torque is better, and it takes the fuel better at the top end (much stronger on the high way). EGTs are on average 75 degrees lower under all conditions compared to stock, but keep in mind that I did change the cam too.
My personal recommendation to anyone who needs to be convinced that this is a good thing to do, is not to do it.
