Fuel Leak around an injector??? - Toyota Nation Forum : Toyota Car and Truck Forums

I just bought a 1990 Toyota V6 Deluxe extra cab (120K) and you can smell gas coming form the engine and in the cab when you are stopped. I checked the engine out it looks like there is some fresh gas around the injector underneather the intake manifold (I don't know which number it is). Is is possible the the injector is bad? Or could it just be a faulty seal? Please let me know what the problem might be so I can get it fixed. Thanks for your help.

If it appears that the injector is seated properly in the head and also in the fuel rail then it would have to be a bad seal. I've never heard of them cracking before.

Thanks for the response. Do you think it could be a problem with the o-ring on one of the injectors?? Let me know, if there are any other seals that I might need to get replaced...

Take off your fuel rail and pull the injector that's leaking... just take a look at the seal.

Thanks. I will see what I am dealing with this afternoon after work.

Well, I worked on it yesturday and got to the fuel injectors underneath the manifold and I found the problem. 2 of the injectors on one of the fuel rails (the side that was leaking) were cracked. After I saw that, I think it was pretty obvious that that was the leak. So instead of buying new gaskets I have to buy 2 new injectors at $65 a piece which really stinks since I just bought the truck this past Saturday.
