    Thanks for the info. The helicoil was what I was going to do but wasn't sure if the bolts set in a water jacket.

    No worries. There shouldnt be any water near the head bolts anyway as they are just holding the cylinder head onto the block :)

3 things you can do here;

1 You can re-tap the hole one size larger and use a larger diameter bolt or stud. If you use this solution the component being bolted down will have to have a clearance hole drilled in it to take the larger diameter bolt or stud

2 If you're dealing with stripped stud hole you can re- tap the hole one size larger and use a" stepped " stud . One end is the larger thread the rest of the stud is the original diameter and thread.

3 The best solution, particularly if your dealing with a thread in an aluminium casting, is to fit a thread insert. These are sold under a range of names e.g Helicoil, Recoil, and come as a kit made up of a tap, a quantity of thread inserts and an insertion tool. Each kit only covers one thread size.

Hope this helps

SOURCE: I have a 2000 ford focus 2.0 zetec dual overhead

all Zetec engines (2.0 DOHC) are NOT interference engines. There are deep reliefs cut into the top of the piston to clear the valves when they are fully extended. There will be no valve damage if the timing belt breaks on a Zetec engine.

SOURCE: 2000 honda civic sir 1.6 dual cam vtec head torque

The Head bolts are located below the cams, so you have to take the cams out to get to the bolts.
The torque specs for the head bolts in sequence is 20, 40, then end at 63ft lbs. Be sure to apply anti sieze or dip the head bolts in oil, before you torque them down or you might pull out the threads. (Not a good thing TRUST ME!)
Hope this helps.

There are no timing marks. Special tools are required to lock the cams and crankshaft in place while the belt is reinstalled.

How to remove cyl heads


Buy a chiltons manual that's specific the the cyl heads your trying to remove. I'm guessing your talking about heads on a car ? By not including a make, model, year , engine size , diesel or gas, overhead cam, naturally aspirated, turbo, fuel injected, carbureted there is no way to answer the question you are asking. Your biggest concern should be on how to reinstall them. Reinstalling heads are far more complex than removing them. All heads are different in the pattern in which they are tightened down ( to prevent warping ) . A specific amount of torque must be applied to each bolt. Some bolts require thread sealant because they pass through the water/coolant passages in the engine. Failure to do that will result in water leaking into you combustion chamber thus ruining your engine as well as your new head. Also the thickness of the head gasket must be correct because to thin or to thick of a gasket will change your engines compression ratio . The gasket thickness can also change your cc's in the combustion chamber. A gasket that's to thin can also allow the exhaust or intake valve to hit the top of the piston on the compression stroke. If your dealing with an overhead cam or dual overhead cam engine then the proper setting of the camshafts when reinstalling the head or heads is crucial . The above only pertained to gas engines. If you have a Diesel engine then things change dramatically . The pressures in the cylinder head combustion chamber area on a Diesel engine is unbelievable . One small mistake or oversight on reinstalling a head on a Diesel engine can be catastrophic .

Hello, does my 2001 Hyundai Accent have a dual overhead gasket or a single over head?


There is no such thing as a dual overhead gasket or a single overhead gasket.... there is, however, the existance of a dual overhead 'cam' and a single overhead 'cam'...

Please restate your question

I have found the crankshaft marks but I cannot find marks to align the to over head cams on my car, the dohc are run from 1 wheel. I am trying to re-align the timing belt as i think they have gone off.


if it's a dual overhead cam then each head has two cams and two pully's, a single overhead cam engine has one cam and one pulley on each head. if the belt has more than 60,000 miles on it you should replace it. you need to find out if the engine is an interference engine or not to determine the level of damage caused if the belt has jumped or slipped. your overhead cam timing marks are usually on the cam faces and the backing plate behind the cam or sometimes there's two marks on the cam that you align with the surface of the head behind them. the first thing you need is a diagram of the belt routing and mark positions because timing marks are very important especially on an interference engine. starting or cranking an interference engine with the timing marks misaligned can bend all your valves or even punch holes in your pistons! so proper alignment is crucial, good luck.
