you may need to replace your gaskets on your valve covers and such, the gaskets are vital to engine pressure
take the bolts out that hold the covers to the engine and pull the covers off then scrape the old gaskets off the valve covers real good and make sure where the gaskets contact the heads of the engine that it is also clean, get some permetex and put some on the valve covers where the gasket goes in to hold them in place when you lay the new gasket in place and let it dry for about 10 minutes and then your ready to put the covers back on and tighten the bolts down to about 10 to 15 ft. lbs.
It'll leak pretty bad without gaskets. I soak the gaskets overnight in a pan of water before installing. Seems to help.
YES. The intake gaskets have NOTHING to do with the head gaskets. It is a very common problem that the intake gaskets blow. It is not common for the head gaskets to leak unless the engine was over heated, and I mean HOT.
It will solve the problem. The 3.4 is notorious for poor head gaskets. You can replace the gaskets on the engine without replacing the engine, and that will solve the problem for quite a while. It will be much less costly than an engine replacement.
yes, but what kind of gaskets are you talking about?
Yes is the simple answer. You may need gaskets if you do!
There are many gaskets on any car engine. If you are asking about head gaskets, they are between the cylinder head(s) and the engine block. The cylinder head is under the valve cover. --------------
if the miles on the engine aren't too high, then just replace the head gaskets. if the whole engine is tired go ahead and swap out the motor. its a lot cheaper to do the gaskets then to buy a new motor.
Head gaskets are supposed to last the life of the engine. There is no "care" specific to head gaskets.
Remove spark plugs and crank engine to blow coolant out. Put plugs back in and start engine. Pull inside garage to repair, or leave radiator cap loose and take to mechanic to replace gaskets if engine is not overheating too quickly to get it there.
you do not need to remove intake manifold to change valve cover gaskets. intake bolts to the block. valve covers bolt to the heads EDIT: Theirs some clearance issues but you can maneuver the valve cover out.
The toughest part of replacing valve cover gaskets is to clear a path to the valve covers proper. On engines with a lot of components, this can be a challenge. Remove the air filter and detach the spark plug wires (be sure to number the wires so you don't mix up the firing order). Remove any other parts (hoses, for example) that are in the way. It's also a good idea to disconnect the battery. Remove the bolts that hold the covers in place and lift the covers out. Cover exposed engine parts with a heavy cloth to keep dirt from falling into them. Use a putty knife to scrape off (carefully!) the old gaskets from the covers, and then clean the cover and engine surfaces thoroughly. Apply a gasket adhesive ONLY to the valve cover side of the gasket. Then re-install the covers, taking care not to overtighten the bolts. Gaskets range in cost from about $10 to $40, and the adhesive is about $2.
You can't. The heads must be removed in order to replace the head gaskets. No other way to do this.
On the very top of the engine there is a intake manifold and the intake gaskets go between the intake and cylinder heads.
Head gaskets are changed on a 97 Chevy Blazer by removing all engine accessories, taking off the intake manifold, removing the valve covers, and taking out the retaining bolts. The heads can then be lifted, the gasket removed, and a new gasket put in place.
usually overheating of the engine
You could blow the gaskets
Engine Overheating is the major cause.
If you are just doing an oil change then 3.3 quarts. If you are doing a complete overhaul where you are taking the engine covers off perhaps to change them or the gaskets then you need 3.8 quarts. This is directly out of the owners manual.
It should be around your mainfold or throttle body, or just follow your top hose that goes to your radiator.
Anything that covers the engine.
The 2003 Jeep Liberty was built in multiple engine configurations/options. For those equipped with the 3.7L V6 valve cover gasket removal and replacement is job and intermediate difficulty. The steps required are the unbolting of the cylinder head covers. Once these are removed the old gasket material and sealant remnants can be taken off. Care should be taken to leave a clean metal surface for the new gaskets. Some gaskets are designed to be installed dry why others require sealer. Once the gaskets are laid on the heads, the valve covers and bolts can be reinstalled/re-torqued. The engine should be run to inspect for leaks. The replacement valve cover gasket for this application is Fel-Pro #VS50594R.
I was not aware that headgaskets were repairable. I have always replaced them with new gaskets. If you mean who replaces headgaskets, then that would be an engine mechanic.
There are two head gaskets in the V 8 1999 mercury mountaineer
