Since intake manifold to head is a at a slant the gaskets are hard to keep in place then gasket sealer usually will be needed.
A light thin layer of orange RTV on both intake and cylinder head will facilitate installation. A thin layer smeared on the head and then allowed to set-up partially first can hold the gaskets in place while the intake is set down on the heads. Let it set up before applying gaskets There should be 4 gasket parts on an 8 cylinder. Be sure all surfaces are clean and flat (true) without warpage. Bolts tightened in correct sequence and torqued is imperative!
No, You don't put anything on Head, Exahust or intake gaskets. CJ actually you do put a 1/8'th inch bead of black silicone on the gasket to ensure no leaks occur and it also helps hold the gasket in place when your putting the intake manifold on. I'm a ford master technician, you ALWAYS use silicone when replacing intake and head gaskets. =DK
To replace the valve cover gaskets on a 2003 Jeep Liberty, the valve cover is removed. The old gasket is then removed from both the valve cover and the manifold (old gasket will come off in pieces on both sides). Then spread the sealant on the manifold, place the new gasket on, then put sealant on top of the gasket and replace the valve cover and bolt down.
FEL-PRO GASKETS,you will need port size,or go to SummitRacing.com
No you do not, you would put oil on a oil filter gasket if it is a spin on type, this stops the rubber from binding and helps it seal.
They can if the heads are cracked ,are the intake manifold gaskets were put on wrong when thay were installed. The heads themselves if thay are good heads will not cause overheating. You cannot put the head gaskets on wrong on a small block Chevy engine.
Which intake gasket? There are two gaskets between the intake manifold and the heads, one sealing the manifold to each head, plus a couple front/rear gaskets that seal out the crankcase oil. To get to those gaskets you need to remove the intake manifold. That involves removing a lot of peripheral stuff that's mounted on the manifold. Another gasket is between the manifold and the throttle body. That gasket is a lot easier, just remove the bolts holding down the throttle body, clean both surfaces and put the new gasket in place. If the engine is idling fast, sometimes it's just the EGR valve gasket. That's just two bolts then clean the surfaces and replace the gasket.
If you need more detailed instructions than this don't try it. Remove the front valve cover. remove the two front bolts from the rear valve cover. disconnect all attachments and bolts from the intake manifold, coolant, vacuum, fuel, electrical. lift the manifold out front side first so it slips out from under the rear valve cover. cut the gaskets in pieces and glue them to the cylinder heads. Glue the cork strip gaskets in place. Use a form-a-gasket sealant at the four top and bottom corners of the manifold. Don't forget, one electrical line runs under the intake manifold. Take pictures before starting and during the job for reference. Now if you can find all the pieces put it back together. 81 and still turning nuts and bolts.
You will need to remove the upper intake manifold, lay it back, then the fuel rail is directly underneath. It is held on by two bolts. Remove these, then put on your new injectors and o-rings, and make sure to put a even coat of vaseline on the o-rings to help them slide easily into the lower intake manifold. Tighten the bolts, put the upper intake manifold on, and you're ready to go. This would also be a good time to replace the plenum gaskets (upper intake manifold) if necessary. This job should take the average do-it-yourselfer about 2 hours to complete.
Well let me share my experience with you on my 99 the intake manifold had a small crack in it , tore it down put new manifolds on it no problems since 150,000 miles later
yes they will bolt on to the block. valve train will be the same. valve covers will be the same. but you will have to buy a different intake manifold. the bolt pattern and gaskets for the intake is different. there are aftermarket parts available for this swap
put new gasket on the intake manifold and bolt carb down to intake manifold and hook up all linkages and hoses.
Taje off the plastic cover with the Cadillac emblem that sits on top of the engine. Take out the intake maniforld to get to the sarter engine. Put in the starter replacement and when reassembling the manifold use new gaskets. Put back the cover on top of the manifold. It's a rather simple job, but be sure to use new gaskets annd do not overtichten (instructions can be found by Googe-ing the Internet). LM
