Thermostat stuck, ran hot twice and died. Won't start after replacement. Turns over but doesn't fire.

have the cylinder gasket checked, it may have blown or other damage might have possibly occured.. The task of getting your vehicle mobile again may be involved and need quite a bit of investigation.
If there iswater in your oil this will indicate that the gasket has failed. Overheating causes expansion in metaly components that may lead them to expand more than they are designed to expand in normal use, this often breaks the seal of the headgasket.
In extreme cases cylinder heads can warp or crack.
You really have a fairly major fault on your hands potentially.
The non start may be some other problem but the above is the most likely eventuality.
I would, also, check the timing belt chain/belt to ensure that is in tact.

Replacing a head gasket in a 1993 buick century

Before head gasket replacement have you checked these
Intake Manifold Gaskets May Leak Coolant or Engine Oil
engine or leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.
Leaking Water Pump May Cause Coolant Loss and Overheating
A coolant leak may develop from the . The may overheat as a result of the coolant loss. A leaking water pump should be replaced.
Headgasket replacement
step 1. undo negative battery cable or completely remove battery and tray.
step 2. remove air cleaner and associated piping if it is in the way to allow access to head, drain cooling system and remove upper radiator hose.
step 3. remove top portion of exhaust manifold.
step 4. remove intake manifold and fuel injection rail as necessary
step 5. remove spark wires and valve cover.
step 6. remove drive belts and top timing cover before removing timing belt find all alignment marks and paint to improve your visibility and aid in reassembly if no marks are present remove spark plug # 1 and rotate until piston is at tdc and check timing mark on crankshaft that it is on 0 then paint the belt and cams anything that has teeth that the timing belt rides on make a mark to aid in reassembly even if you are replacing t-belt at least you can compare to new belt and transfer marks, release tension on t-belt tensioner and remove t-belt.
step 7. remove head bolts start loosening at inside and work outwards reemove head bolts and pay attention to sizing and placement.
carefully check for anything that is still attached to head and if free tap head with rubber or dead blow hammer to free from block and lift straight up so as not to ruin or bend any of the alignment pegs.
step 8. remove head gasket material with non-scratching tools or scrapers or buff pads made for that job. making note of where it was blown.
step 9. decide if you should send head to machine shop to have mating surface made flat again and also to have valves and related parts inspected or replaced. usually about $300-$400
step 10. inspect block remove all gasket material look for pitting or scarring also use straight edge to determine if it is straight or if it needs to be resurfaced by a machine shop.
step 11. install new headgasket and check fit. If all is good reassemble in reverse order of removal and I always like to replace crank seal ,cam seal, water pump, t-belt and tensioner also thermostat, drivebelts, spark plugs, cap, rotor, wires, pcv valve, intake manifold ,exhaust manifold gaskets.
this is just a broad overview hope it helps you will have to get haynes manual or similar for head torque values and what not

Replacing head gasket

It would be possible to do this as the belt will be out of the way but as it is tensioned then the problem will be how to reinstall it with the tensioner in the way. Far quicker, easier and safer to do the job correctly in the first place especially if you have no experience with engines.

Something went wrong, did they reuse the timing belt,when a vehicle over heats and blows the head gasket the timing belt gets fatique.Who ever replaced they should be responsible for it, just work it out with them ,They have to warranty the labor,They did not inspect the part just threw it on.

Will a pt cruiser run perfectly fine with a blown head gasket.lots of white smoke,but runs fine

If i remember right the color of the smoke will tell you what it is and i think blue smoke is water getting into the combustion chamber. The car can run like this for a while. Lots of times the car will run like normal besides the smoke. But the passage in the gasket will continue to get bigger and lead to more serious problems.

How do i replace a blown headgasket

To replace a blown head gasket requires a lot of labor on this vehicle. Its a v6, meaning you have 2 head gaskets to replace instead of just 1. It requires removing air cleaner, disconnecting battery, removing most of the accessories that are belt driven, removing the intake manifold, egr valve and tubing, exhaust manifold on both sides of engine, timing belt removal, valve covers, and a few smaller items. After removing everything on top of the engine, you'll have access to the cylinder head bolts. Removing them will allow you to lift off the cylinder heads. Before replacing the gaskets, you must send them to a machine shop to have the gasket surface milled true flat again. They must also be inspected for cracks (which will sometimes happen with blown head gaskets) which would render them useless.
If this is a vehicle you really like, perhaps consider investing in a quality used motor. Its less labor intensive, less repeat repair, and you may come out saving a few bucks.

How to replace the headgasket?

UNfortunately, this is a fairly big procedure for a backyard mechanic or diy' will need to remove the timing belt which would invlolve gaining access by removing all accessory items, such as alternator, power steering pump, air conditioner compressor (if applicable), and crank pulley !!.....after this is done, you will need to remove intake manifold and exhaist manifold, after draining coolant etc......and then the final cylinder head removal to ge to the head gasket.

I would advise purchasing a workshop manual, and reading through the entire process before attempting it !!

I changed my headgasket on my 1999 dodge avenger and water pump spark plugs even the hydraulic timing belt tensionerand it is still misfiring

Why did you change the head gasket Patrick,
Was the engine missing before you did this,or did you over heat the engine from low coolant?
If the miss was there before you may have burnt a valve,
