Hello,
I am working on a 2.7L rebuild and am battling some stuck piston squirters...
The case has already been to The "A-List" Shop for a full R&R and they say that all the squirters were tested and working when it left... the receipt says that they cleaned them, no mention about replacing. Bottom line is that it regardless of if they were working when the case left them, a few are not working now, and they obviously need to be.
I have the Stomski Racing piston squirter cleaner air-hose attachment and a big-a$$ compressor, so I feel like my testing methods and understanding of how the squirters should operate is OK.

I have tried soaking them w/Seafoam, brake cleaner, PB Blaster (although kinda hard to make sure any of that gets in to them)... and #3 & #6 will not flow any air. Also, the ones that do work, don't seem to flow consistently when compared to each other. Some seem to flow more air and at lower pressure than others. I'm a little frustrated as I'm not relishing boxing the case back up to ship back to them. It was a 5 month wait to get it back the first time around...
Just looking for some experience based ideas to getting them unstuck or info on replacing them... Are these a DIY replacement? or is sending the case back really the best long term course?
Thanks,
Tom
