g2/m14 barrel and piston

Post by rsimo »

Hi all,
Just rebuilt a 64 CSR14 motor, Albeit not all CSR14 any more, again
We have an oil leak 3 fins up from base of barrel, around the pushrod tunnel area. Also, there Feels like a crack inside the tunnel, so I'm assuming that's the problem and the barrel is no good.
......(edited by Adverts Editor, Richard we don't allow wanted adverts in the general forum areas. You are welcome to place an advert in the adverts section although the solution suggested below may be cheaper and there is always the possibility the replacement barrel has the same fault)
Thanks in advance

That was a common problem on some L/W barrels the oil way is perilously close to breaking through and is porous. The cure is to have an engineering company bore out the oil hole and sleeve it.
