Would fixing head gasket make your car a rebuilt?

Question

Head gasket needs to be machined.

Answer 1

The extent of engine rebuilds varies wildly, but typically the main parts being replaced otherwise repaired on a rebuild include valves (replacement or resurfacing), cam shaft bearings, crank shaft bearings, piston rings, wrist pins on the connecting arms, and often as not an oil pump. There are also a number of lesser parts involved as well as some additional labor, such as honing the cylinder walls to, at the very least, take the glaze off of them so that the rings will seat better. Sometimes the pistons themselves are also replaced. You also usually take the crank shaft out and have it reground to accomodate oversized bearings, and often the cam shaft is also machined.

As it is necessary to remove the cylinder head to perform all of these tasks, the head gasket is also replaced.

However, in your case, what has happened is that your cylinder head has warped a bit, probably as a consequence of overheating at some point, and because it no longer presents a flat smooth surface to hold the head gasket firmly in place between it and the engine block, the gasket has failed, There a two typical remedies for this problem. If the cylinder head is not too badly warped you can remove it, and take it to a machine shop which will plane the surface on the bottom of the cylinder head back to flat and then install a new gasket. If it is warped so much that it cannot be planed without removing too much material then the cylinder head has to be replaced.

Still even though the work is considerable and the expense of paying someone to do it is also fairly substantial, it does not constitute a rebuilt in and of itself. That involves a good many more parts and other additional labor.

Answer 2

It's not the head gasket but the cylinder head itself that needs to be machined. Which means you have to remove the valves and in the case of overhead cam engines, the camshaft.

So you would be wise to at least partially rebuild the cylinder head.

This has nothing to do with the lower part of the engine, which will remain the same old engine and thus not rebuilt at all.

Answer 3

No. Rebuilt usually indicates replacement of internal components and/or machining. Head gasket needs to be machined?? Do you mean the head needs to be machined?

Answer 4

No, A rebuilt motor consists of new main, rod and cam bearings, piston and rod inspection, new piston rings, gaged and honed cylinders, new valve guides, retainers, springs and seats as well as valve inspection and a complete engine gasket kit, Installed.
ie.. the meaning of rebuilt! not serviced, you serviced the head gasket by replacing it.

Answer 5

no, a rebuild or an overhaul as i call it, is when you replace all worn parts, seals, gaskets, bearings, and recondition usable hard parts. by only replacing the head gasket your only taking care of the top end of and engine. The bottom end usually has as much wear and is just as or more important than the top end. doing one without the other is just patch work.

Answer 6

No, just a repair. If your heads need machined, that would mean that heads are rebuilt....not your engine.

Answer 7

No
And you don't machine a head gasket...

Answer 8

no all you are doing is replaceing the gasket.

Answer 9

No! Just a vehicle which has an engine that has undergone a major repair. Welcome to the world of today's automobile "Ownership Club".
