HOW TO FIX A BLOWN HEAD GASKIT?


Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

How to replace the intake manifold? I have a 96 grand cherokee v8, unable to replace the thermostat housing to the manifold because one of the screw holes cracked off on the manifold.


Position The Intake Manifold Gasket On The Engine.Dowels May Be Provided To Hold The Gasket In Place During Manifold Installation.. The Use Of Silicone Sealer Is Required. Especially Where The Front And The Rear Seals Meet The Side Gaskets On V-type Engines. Installing An Intake Manifold On V-type Engines Can Be Difficult. It Is Critical That You Use Sealer Properly On The Engine To Prevent Vacuum,Coolant, And Oil Leaks.

Start All The Fasteners By Hand Before Tightening. This Will Aid In Bolt Hold Alignment. Then Torque The Intake Manifold Fasteners To Specifications. Use The Specific Torque Pattern Given In The Service Manual.. Basically The Pattern Will Be A Crisscross Pattern

How to install a intake on a big block chevy corvette


That depends on type of gasket being used. Some fel-pro gaskets have sealant built into the gaskets, I have used some sealant to help hold gaskets in place around bolt holes during installation but that's not always necessary...and yes there is a torque sequence for intake manifolds...example given in link.

The balancer should be torqued also...85 - 90 Ft-lbs if I remember correctly. The balancer should be all the way back when completely torgued, if not you may need to check for clearance problems.

Leaking anti-freeze from my intake gasket


The corners of the intake manifold have coolant pasages. The lower intake manifold gasket will need to be replaced. There is an updated manifold gasket, manifold bolts, and torque specification. Call the chevrolet dealership and see if they will extend the warrant on this repair. It is a very common problem with this engine. Thanks Steve
