Gasket question

So I narrowed my gas in my oil problem down to a bad injector. #4 would just turn on and not shut off when the pump was charged. So i broke it all down and have new injecors sitting ready to go on, but my question is this. Can I use the gasket I just put on the upper manifold again or so I have to replace it. Keep in mind this is a fresh rebuilt motor and the gasket has maybe 50-100 miles on it. Just trying to figure that out before I start putting her back together. Thanks.

In reality if its not ripped you could re-use it. But thats your call. I did the same thing, put the top half of my motor together, a few hundres miles later I swapped back to the stock injectors, had the intake off and I reused the gasket because it wasnt ripped, if it had ripped when I took it off then I would have replaced it. Im sure other people will say to def replace it but IMO if its not ripped, re use it. Only cause it has very low miles like you say

Re: Gasket question

I have reused that gasket and throttle body gasket before. If it has any imperfections, I error on the side caution and replace them.

My vote is, assuming undamaged of course, is reuse the thing.

Re: Gasket question

I've seen uppers with no gasket at all.... not even RTV.

If it's in good shape, it'll be fine.

Thats what I figured, it is definatly in good shape did not even stick when taking the upper off it came right off. Thanks guys.

That's why I apply a light coat of silicone grease to both sides of some of my gaskets so that they *won't* stick and I can reuse them...

Re: Gasket question

I don't know guys. Did I do something wrong? But I didn't take any manifold off to change my injectors.

Re: Gasket question

If you could change your injectors without taking the upper manifold off (plenum) more power to you buddy. I could not figure out a way to do so.

Re: Gasket question

I changed all of mine out it was easy. Just loosened and pulled the fuel rail from the injectors. Pulled the old injectors out. Popped the new injectors in and hooked everything up. I don't know I may be missing something on my engine or something. But on mine it looked pretty straight forward.

Re: Gasket question

I could not get my hands in there but if I could have I would have done the same. Would have saved alot of time and effort.
