I keep getting water in the 3 and 4 cyl. The injector is broken where the bolt goes thru. Should I just use a washer to hold them down. Also the 4 and 8 cyl seem to have a smaller head bolt holding the injector or may be stripped and I cant get them out. Does anyone have any ideas?

 

First off, something is leaking coolant into the cylinders. Look at the intake manifold and see if you can find any coolant leaking out. It's either leaking into the cylinder through the spark plug boot or you have a blown head gasket. Best thing to do is a pressure leak down test, to see where the leak is coming from.

as for the injector bolts, do not jerry rig it. you need to re-thread it so you can bolt it down.

 

My bad for not explaining. The water gets in when it rains and I go through puddles. The injectors are plastic and part of it that forms the screw hole broke off.
