Exhaust Manifold Installed... Some issues...

Swapped my exhaust manifold today because my old one was cracked.

Problem 1
Well I followed the guide that suggested pulling the fuel line... So I did so. Now I see bubbles coming up from a couple of the injectors when the engine is running. Does this mean I didn't seat them all correctly? If so any tips on how I can get them to seat correctly?

Problem 2
I disconnected the negative battery terminal. Now when the car is on the battery gauge reads like the battery is dead. After it ran for a bit it came back up to normal, but quickly went back to dead again? Did I loosen a wire somewhere I'm not seeing?

Problem 3
The belt is squeaking VERY loudly.. But only when I throttle up. Otherwise it's quiet as a mouse. Is it likely I over tightened or under tightened it? It appears to be coming for the alternator side.


Thanks in advance for any help you can offer!

Problem 1 - Did you make sure when you removed the fuel rail that all of the o-rings remained in place? Pull the fuel rail and make sure each injector tip and seat has an o-ring and they are in good condition. Replace if necessary.

Problem 2 - Weird. Haven't seen this one. Best I can say is remove the neg cable again and clean it and the post thoroughly and re-attach.

Problem 3 - Make sure the belt is seated correctly. When you press on the belt with mild pressure it should only deflect a 1/2 inch or so. If it deflects more, tighten it. If doesn't deflect then it's probably a bit tight.

Good luck.

Thanks for the response. I did make sure the o-rings were there. I cleaned them a bit but I didn't remove them to clean them well. I'm tempted to just get some new ones and put them in. I'm really concerned I didn't seat them correctly on the intake side. It was pretty hard to get out, and I couldn't really press it down because the bolts notches blocked me and I did t want to twist them.

Replace them and clean the battery terminals...

Check the charge-back wire from the alternator to the positive post on the battery. A loose connection at the alternator will make the volt gauge either move erratically or not move at all.

On the injector o-rings it's cheap to replace them but a film of engine oil on them before you install the injectors will help them slip into place easily and help create a good seal. Also be sure the holes for the injectors in the intake are clear of debris.

Swapped the o-rings.
Tightened the battery cable.
Replaced the belt.

Good. Good. Good.

She's running great!

Thanks all for the quick responses and help.

Now I am just crossing my fingers that the radiator leak I fixed by tightening a host was all it was... I poured a crap load of coolant into it just kept soaking it up. I am worried it is leaking somewhere I can't see a drip like the engine. The reservoir seems to be holding now finally. Fingers crossed!
