This happened to my buddies eta and it ended up being the ICV and a cracked hose. That would be a good place to start.

*shameless plug* I have an L shaped ICV for sale if ya need one

Your sentence structure is terrible. It takes more effort to try and figure out what you are saying, than to give you advice. I'll be the ass-hat that tells you to search.

This is the opposite of what you are having trouble with, BUT it tells you what you need to check in order to diagnose the problem. Seriously, lazy people like yourself are starting to ruin the site.

I would know too, I helped destroy a photography critique site for professional level work. I was a noob with good shots, but I had nothing that was worth sharing. The site eventually closed due to the overwhelming ratio of noobs to actual knowledgeable photographers. Live and learn fools....
