Cant get the Mainfold off

[lsgunner28]

Hi all,
is there some trick besides removing all of the bolts to get the intake manifold out? it wont budge forward or up..
thanks

Auto or manual? I believe autos are really tight around the dipstick tube.

Dumb questions I know, are you sure you have all the bolts out? Have everything disconnected that's needed to remove in front? Has it moved at all?

Try getting a flat head screwdriver under the center of the intake and lightly pry up. There is no gasket in the center so you should be alright. Shouldn't take much at all, Ive never experienced any problems with the manifold sticking.

ive had "all" the bolts out before, but someone had snuck in behind me and put one back in.

There are 10 8mm bolts by the way.

Manual, yeah i think so, 6 are completely out, 4 cant come the whole way out bc of the cowl but they are all loose. the only thing i can see that is connected is the 1 fuel line. I pryed a little bit and it only lifted like 1/16-1/8th.
i dont know why its so tough, everything is out for the most part bc I am doing it along with my LT install.
any advice will help!
thanks

I don't know why its sticking on you, but on a little different issue, have you unplugged the brake booster line so you don't end up breaking your oil sending sensor?

109,xxx miles maybe? and yeah did that and unplugged 2 sensors on the back, didnt get the little vacuum line yet but was hoping too after i got it loose.

I always use masking tape to hold the bolts up. Pull the bolt all the way up, then just fold the masking tape over it. That will hold them up for you. Other then that, I cant imagine any other reason it wouldn't come off.

Does anything from this step by step write-up help you.

I have been following this to the T, I actually have it memorized. lol

[shady milkman]

i use clothes pins for the bolts ......besides that with the tb off ...there isnt really anything holding it on besides the brakebooster

[lsgunner28]

ok so i can get a little rougher on the old girl you think? is the valley pan safe to pry off of?

[c5z28]

Did you unplug the opsu?

[lsgunner28]

i think so.. lol tough to tell for sure, i cant see any other sensors with my mirror..

[c5z28]

Well keep the last 4 bolt held up w/ tape
if you lift the manifold you can slide your hand under it and feel the opsu emerging from the block
unplugging the map sensor on the back can be done when it is halfway out.
I have to think it is the bolts or the booster line getting caught up on the opsu that is holding you up.

[lsgunner28]

found my problem, cant count.. lol too bad i think my opsu is broken and i didnt hardly move it.. :-(

[lsgunner28]

what does this sensor do or called? lol i called it the opsu and told them about it at advanced and they had no clue what i was talking about..

Kinda figured there was a sneaky bolt remaining

Oil Pressure Sending Unit. It does exactly that also.

yep lol and ok i wonder if that is the same thing as the oil pressure switch? that is what i ordered bc it has the right plug lol..

When I got mine loose I barely lifted on the front and I still broke the opsu. I also had to buy a special socket to install it.
