Is it possible to repair injectors?
================= What aren't they doing, and what have your tried so far? What kind of Honda? More info makes for more (intelligent) responses. 'Curly'
Yes, it is possible to replace injectors. A shop replaced the #1 and #3 injectors on my '89 Prelude Si a little while back. Right now, I have one of the original ones leaking a little bit, so I'd like to change that one as well. However I'd like to try changing them myself and saving some $$ on labor if I can. Just don't know how to do it or if I should even attempt it. I know there are gaskets that need to be replaced as well, but it's something I've never done before..... -Dave
Hi. I think they are leaking a little, so that after about 2 hours after it has been driven it starts immediately as if it has enough gas and air inside the cylinders, which it shouldn't. So I would like to know if it is possible to repair them not to leak any more? Honda Civic Coupe 1.5 iLS, year 1995, 74 kW (101 PS) Mickey
=============================== We had a leaky injector on our Odyssey, and the (overnight) symptoms were the exact ones described in the Owner's Manual for 'flooded engine' (which you'd never expect on an injected engine). We ran ethanol-enhanced gas thru it for the next few tanks and it never reappeared. Techron injector cleaner is supposed to be an even better solution, because they do get gummed up, and stick open. A google groups search for 'leaky injectors' might turn up lots of answers. 'Curly'
If they were leaking, it would not start immediately - you'd have problems with long cranking and stumbling due to flooding.... which might be helped by holding the throttle half open. I don't think you have a problem. Rgds, George Macdonald "Just because they're paranoid doesn't mean you're not psychotic" - Who, me??
Doh! I should have read that more carefully. Sorry. However I did listen to a conversation between a mechanic and customer some time ago. He said it is possible to repair it but normally not worth repairing vs. replacing. Wonder what the cost difference would be.... -Dave
I think they are leaking very small quantities of fuel, if they are leaking a lot then you have flooding, thet happened when i first celaned them and 1 of them wasn't even closing. After another cleaning it starts too soon, as if in a few hours enough fuel leaks into cylinders so that they fire immediately. I'm 99% sure that this is what is happening. I wondered if injectors can be broken apart and repaired so that they don't leak? me??
Depends what you mean by repair. There's a little needle (pintle) that fits into a nozzle (anvil) and when it opens, the gas spurts. <http://www.abheller.com/parti.html> <http://www.elsbett.com/gd/image22.gif> <http://www.thedieselstop.com/contents/images/69injector13.jpg> or variations on the theme <http://www.bwdautomotive.com/datastream/spring2000_data_stream/page4.html> Two possibilities for leakage: either some bit of crud is stuck in the hole and prevents the thing from closing, or else the needle is worn and doesn't seal well any more. Or both. If it's crud, it's possible you might be able to clean it out with injector cleaner of one variety or another. <http://www.bwdautomotive.com/datastream/winter_data_stream/page5.html> If it's wear (new = <http://www.grease4sale.com/lubricants_specialty_products/fuel_stabilizers/lb-dzl-pep2.jpg>, worn= <http://www.grease4sale.com/lubricants_specialty_products/fuel_stabilizers/lb-dzl-pep1.jpg>) in theory it can probably be repaired with a new pintle, but I've never heard of anyone trying, or any kind of repair kit, advice, etc. for anyone who might try.
