Injector cups.

I found mine durring an injector swap. I had the injectors out and the old cups cleaned out, and decided to quit for the night. I pluged the block heater in the next morning to warm it up while I was installing the injectors. I went back in the house and had breakfast, came out about an hour later and went to install the injectors.

So, as I was checking the holes I noticed there was some fluid in the bottom of the cups. So I grabbed a few towels and cleaned the cups out again. As I went to drop the injector in, I again saw fluid in the hole. This is when I thought I was going crazy, fresh towel and wiped the hole again. I didn't feel like oil or fuel, only one way to find out, tasted it and it was coolant.

So long story short, the block heater warmed up the coolant enough to make just enough pressure in the system to leak past the cracks in the cups.

After about 3 hours, my block heater will get the water temp up to about 140 degrees.

Good luck.

it's NOT the copper crush washers on the injectors...

it's the injector cups.

the BRASS inj cups that are pressed into the cyl head.
