HOW TO UNSTICK THE INTAKE MANIFOLD ON A4.3 LITRE 93 CHEVY i can,t pry it off.

many times the intake won,t just lift off.sometimes you must use a pry bar to lift it up.you must put the pry bar under the edge and carefully pry it loose but be careful not to break the edge.i assume you double checked to see if you missed a bolt.good luck.

Left rear side of intake manifold. Usually silver in color with plastic cap on top of sensor with 2 wires attached to black cap. Cap had plastic clip that needs to be pryed loose. Caps pull straight up when clip in loosened.

take a hammer or sledge and beat on the tire NOT THE RIM in a X rotation. wheels are probably aluminum and get oxidised onto the hub. as long as you hit the rubber tire you will not damage the wheel. It might take several minutes of banging on it to get it loose. when you are going to reassemble the wheel and hub make sure to wire brush the hub and wheel clean then take some Antiseize and put a nice amount around the hub where the rim makes contact that will help it do not happen again

It has two of them. Sorry to say that they are under the intake manifold and you must remove the intake manifold to gain access to them.

If all bolts are off take a screw driver and find a spot where you can pry the intake off the heads and block. The get pretty stuck to the gaskets and sealer after a while. Pry in as many spots as you can to distribute the pressure and lift it as evenly as possible.

If you are referring to the intake manifold, be very certain that you have removed all of the bolts from the upper and the lower intake manifolds. Here are some diagrams that might be useful to you.

If you are certain that all of the bolts are removed from the manifolds, then you can break the seal holding the intake manifold by using a large screwdriver, wedge it between the intake manifold and the cylinder head and you should then be able to pry up the intake manifold and get it to break loose.

You did not specify what engine you had so these diagrams are for a 1998 3.8 litre V-6 engine. I hope that they will be of any use to you.

remove the throttle body,remove the valve cover,remove the intake manifold bolts. you SHOULD be able to GENTLY pry the intake back enough to remove the gasket. be careful as to not scratch or ding any surface that comes into contact with the gasket.clean the gasket surfaces thoroughly and install the gasket. install in reverse order. make sure that you torque all bolts down to specs and in the order called for. on a final note...yu may have to remove the EGR valve to get some clearance to make it easier

You unbolt the intake manifold, remove the old gasket, install a new gasket, and bolt the maniforld back on.

You may have to remove sensors or hoses that block removal of the intake manifold.

you'll need a torque wrench when you bolt the manifold back on

Hi, you need to apply some presure to it but it will come out ,try a pry bar , C1

pull the valve cover and pry the valves dont but do not force. you can use some WD40 and spray and try to get it loose
and if it doesnt come loose your that much closer to removing the head
