Finding instruction to remove/replace the head on a

My timing belt broke. I am told that a head job would more than likly fix this engine. I need the instruction to R&R the heads. Any tips on what else to look for, that may be a problem when this happens. I use to be a mechanic (30 years ago). I am capable of doing this job. just need some insight, and heads up on proper procedure. Thanks in advance.

Most timeing belt engines are non interference engines any way ...there are a few exceptions..but most won't cause valve damage .regardless of the rpm..not enough engine info for me to give a specific answer .

It depends on whether it was idling or being up in revs when it failed .
May have bent valves & or damage to pistons & or combustion chambers in corresponding cylinders
If you remove the spark plugs & try rotating engine by hand to see if it locks up.

SOURCE: 2004 aveo timing belt broke, all valves bent

just go to any junk yard and find a used deawoo lanos and pull the head if timing belt was not broke, if it looks good, its a exact fit 100%, no special tools needed, just normal wrench set and torqe wrench. after head is installed, get a gates timing belt only.

SOURCE: removed distributor to change head gasket, now timing is way off

On some 4.3 engines, when the timing marks line up, the #4 cylinder is the TDC. So you may have to point your distributor to #4. And look at your cap, sometimes, where the #4 wire joins the cap, the wire "inside" the cap may run to the other side of the cap, so look inside to see exactly where your rotor should be pointing.

SOURCE: 97 cavalier convertible 2.4 twin cam engine..

It sounds to me like you have a vacuum leak or maybe a vacuum line connected in a wrong location. To find this if it's a leak, have a mechanic perform a vacuum test by blowing air through the intake. If there is a leak you will here air being forced out from the leaking location. Some shops also use smoke.

Hope this helps.

SOURCE: Replacing head gasket on my 94 cavalier

there is not a way to not affect the valve timing, the cam belt must be replaced in a repair like this, when u put it back together you must reset and confirm all the valve timing marks are in correct alignment, just no way way around this, if the cam is timed right the engines ignition timing is correct as well and will require no adjustment. this answer applies to all engine that use a cam drive belt.

I have a Suzuki vitara 1990 soft top timing belt broke just wanted to know if it would have damaged anything else when it broke?


Yes . The valve stem will be bent so you will need a head job to fix them. To do the job properly replace the cam and crank shaft oil seals , tensioner pulleys and or hydraulic belt tensioner. Do not use 2nd hand belts. Remove all traces of oil from the area as oil is the biggest killer of timing belts

I have a 2004 Dodge NEON with an interference engine that the timing belt broke on. What are the chances of valve damage and about how much does that cost to fix?


The valves will be bent and you will need a head job done. The time to do the job outside head reconditioning would be around 4 hours labour and the parts will include valves, head gasket kit, timing belt, adjuster pulley, and if the job is done properly crankshaft and cam shaft seals as oil is the main cause of belt failure.

This is a 4cyl diesel Beetle. The timing belt broke while driving. Dealer claims no damage done, replaced belt and car was driven for a few weeks. Began to start a bit sluggish, dealer said glowplugs...


my books show it as a interference engine in which case valve damage is most likely to occur
however if that was the case , it would be having a miss from the start and would not run 2 weeks before something happened
if a valve spring breaks there could be valve piston contact but it is doubtful if that would destroy the engine but again breaking valve springs is rather rare on diesel engines
the engine would not just quit but would rattle and bang it's head off then develope a big noisy miss from a hole in the piston
so I suspect a timing belt problem from when they removed/replaced the head after the glo-plug fix or a crank/cam shaft position sensor or wires ( possible faulty connections for the cam shaft)
I would suggest finding an accredited service center for a proper diagnosis and quote for engine repairs

My timing belt and balancing belt broke on my 1998 mitsubishi galant es and my husband put the belts back on in time but the car won't crank. The engine turns over when cranked but won't start. ...


Are you sure it was timing belt? If so. When you crank the engine, does it turn kinda fast without making a wump wump sound? When the timing belt broke it may have done some hidden damage. Its possible it may have bent the valve stems by piston hitting them because the timing to move them was off. You need to perform a compression test on all cylinders. Borrow or rent a compression gauge from an auto parts store. They will tell you how to use it, what to look for. If compression is bad, you may have to remove the cylinder head and have a valve job done. Except that you need to replace some of the valves. This calls for some skill or at least good apptitude in mechanics. OR somthing did not go right with the timing belt install.. Thats all I can do for you now. Check the compression. Good luck.

My 95 Lexus ES300 timing belt broke. The cam gear is exposed. I like to know how serious is this problem? And, how much is reasonable to fix?


This is very serious as the pistons come up and hit the valves and bends them. its hard to give a price without knowing how much damage is done but i can say at least 1500.00 to 2000.00.

Timing belt broke is this a low tolorance enging


A 1991 GEO is worth scraping if this is your problem
A water pump is also needed to replace with the belt
It is a rule of thumb for the belt drives the pump as well
Think about selling it to a local kid as his first car that he has to fool with. The monet to fix it is really not worth investing into it
The fuel pump for these cost more than the worth of this car now

Timing belt broke


I hate to be the barer of bad news, if your timing belt broke, you will probably need to replace the heads also. Not a small job. When a timing belt brakes the timing is out (of course) and when that happens the valves hit the piston and bend. So remove the water pump belt, a/c belt and the alt. belt. you will have to remove the harmonic balancer through the right wheel well. Before you remove this make sure number one piston is at the top of the cylinder. Then unbolt the black plastic timing belt cover, clean all the debris out. When this is done check the all the pulleys in there to see if they are nylon or metal, if they are nylon replace everything (nylon cracks over time from stress). Once that is done you will have to remove the heads to check for valve damage. If damaged you will have to get new or used heads or have yours rebuilt.

Daewoo Leganza 2000 timing belt broke


Hi.
If the idler pulley, broke, with the car running, (I think is the most probable), There is no way to fix the car just replacing the timing belt and the idler pulley. This is an interference engine, that means if the timing belt or the idler pulley breaks, you need to replace the whole cylinder head, that's because the valves are bent. I just fix my daewoo, I tried first to just change the idler pulley and set up the time, but it did not work. I had to replace the whole head cylinder, timing belt and pulleys.

I got the information to set up the timing belt from a Library, The program is Mitchell on demand.

Thanks
