injector question

Mon May 19, 2014 9:08 pm

I got a set of injectors refurbed about 14 months ago and they've been sitting around ever since. Is it safe to assume that at least one of them will be stuck now?

Not necessarily, depends on how they were stored. You won't know for sure till you've tried them or had them checked.

For the first few months they were still in the wrapping they were returned in and since then they've been fitted to the head of an engine that hasn't been used. I want to fit the engine in the next couple of weeks but don't want the hassle of removing them when it's already fitted.

Check them by applying 12v from a battery ( be careful not to short the pins of the injector when doing so) and if they click ... they are free

Injector tune do say in their blurb that will have come back with the cleaned injectors that one or more may well stick,despite being freshly cleaned.

I have had two sets cleaned,and replaced them upon receipt,and sure enough,each time one stuck.Easy to tell which one,the exhaust on the stuck one is cooler than the others.The recommended way of freeing them is to tap them with a blunt instrument.

Tapping them is a good starting point but from what I've read it doesn't always work. I'll give it a try and then the 12v method. Cheers for the replies.
