I'm a mechanic, And have my own buisness . I charge 350.00 for parts and labor.
But my labor rate is only 50.00 a hour, And parts are about 50.00
If you have to ask that question you probably should not attempt the job your self.
No reason to if the intake gasket is the only problem you have. If engine was running smooth and was not overheated then there is no reason to fool with the HEAD gaskets
Yes you should replace the thermostat now to insure trouble free operation afterwards, actually as long as the main bearings were not damaged from the intake leak, you should also replace the head gaskets at this time, use only felpro gaskets and you will have troublefree performance for years to come. These are good torquey engines, gm just went cheap on the gaskets when new
no you need to replace the lower intake gaskets . P.S. should have the rear head checked for leaks also they are known to leak also
You will need to replace the intire intake Gasket if you are SURE it is leaking were the gasket goes. On most of those engines it will be a BAD intake and ford redesigned the intake manifold. But it sounds like it has already been replaced scents it has got the alum. crossover bar. You need to look real close at the gaskets.
Theoretically, under normal operating conditions, and proper maintenence, intake manifold gaskets should last for the entire life of the vehicle. To my knowledge, there is no prescribed routine replacement interval for intake manifold gaskets. Of course anytime a head(s) is removed, then new gaskets should be used in reassembly.
For sure, replace ALL the gaskets involved. When you purchase, ask for a head gasket set and you will get all the gaskets that are used.
You have to remove the upper intake to even get to the fuel rail. make sure you have all the o-rings seals and gaskets in between cause you should replace them. Really its worth it to take the car to a mechanic.
Find where the leak is and replace the hoses or gaskets which are the culpret.
Did you (whoever built the engine) use the supplied rubber gaskets for the block ends? If so, you may want to remove them and use a nice bead of Silicone Gasket maker for those, and tie into the intake gaskets as well. Those rubber gaskets like to leak badly. Just be sure NOT to use anything on the actual intake gasket whether intake side or head side and you should be good to go.
You will have to remove the intake, and replace the gaskets (they are reuse able but you should have new ones on hand in case they are damaged. The spark plugs installed in the engine are designed to last for 100k miles, unless you have a misfire, then there really no reason to replace them.
theres no way you can change the head gaskets without taking off the intake manifold, its not hard to do. plus if your going to change the head gaskets it would only be smart to change the intake gaskets also.Answerand if your talking about the exhaust manifold, you did'NT specify, I'm sure you can but it will be no fun at all, plus u should change exhaust gaskets if your going to do all that work anyways so you don't have to worry about them down the road.
