    The car is making the exact same sound it did when the timing chain went out the last two times, it makes a loud noise, like a jet.

  • bcheatham70 Sep 24, 2009

    Yes it is more like a clanking sound, it is definately that timing chain.

  • bcheatham70 Sep 24, 2009

    I just wonder does the entire engine has to be broken down in order to see what is causing the problem?

I dont think a timing chain can make that sound "like a jet'.. When a timing chain goes bad - it will either fall of the gears or make a clanking sound..

The sound you describe seems as though it might be vacuum related or exaust or intake - somthing of that nature.

    i would have the cam inspected.. Something must have some play in it to cause the chain to become loose in such a short period of tim.. The top end gear the chain connects to - and then into the top end where the cam shaft is. maybe the bearing are bad..

You probably have a timing chain with and oil or hydraulic in a sense, tentioner that works off of engine oil pressure.This gets clogged and you lose tension to the chain.

My timing chain broke on my toyota 22re engine did i bend any valves and how do i check? it was idling at the time and it just died i diudnt hear any weird sounds it just died


Don't concern yourself with thinking you may have a bent valve or any other destruction inside. Just replace the timing chain and go on with your life. I've been thru timing chains also, nothing else ever happened. And I know these 22re's inside out, for the past 20 years or better. You just can't destroy them. One I just took of the road for frame repair has over 500,000 miles on it. Replace front main seal and sleeve twice. Anyway, if you've never replaced a 22r chain, get a Hanes manual at any Pep Boys auto parts outlet to find out how to do it. Just be sure to follow the instructions explicitly. You don't want the timing off evn a single tooth.

How do i correct timing chain and gears installed correctly but #1 cylinder was in wrong position


What you are saying cannot be true. IF the timing chain and gears were installed correctly, the #1 cylinder would be in the correct position. Most likely what you have done is that you have the crankshaft in the wrong position. The crankshaft rotates twice for every rotation of the camshaft. Thus, the crankshaft timing mark will align with the camshaft mark twice - once with #1 cylinder TDC on the compression stroke, and once with the #1 cylinder TDC on the exhaust stroke. You probably have the crankshaft on the exhaust stroke when it should be on the compression stroke. You will need to take the chain off and rotate the crankshaft one full revolution and reinstall the chain. Best guess, IMHO.

95 caviler died while driving, now it will not start. Trying to start, it cranks real rough & catches hard. Any ideas?


If it has the 2.2L engine, and its has more than 60K miles on it, you may have had a timing chain jump. The tensioner for the chains breaks and allows the chain to jump time. They only last about 60-80K miles before this happens, and when it does, it usually bends valves in the head since it is an interference engine. GM knows about this and has done nothing to correct it. You need to do a compression test to confirm the problem. If it shows low compression on one or more cylinders, plan on a replacement or rebuilt head and a new timing chain set. Then either get rid of the car or plan to replace the chain tensioner every 50K miles to prevent it from happening again.

I speak from personal experience here, having had it happen twice on my daughter's 1997 Cavalier.

Timing chains and actuator replaced, now i have a code PO2279


P2279 is the code for Air Intake System Leak. Smoke checks are ok, but hard to see in places like the underside of the intake manifold. SInce your compression is good and even, chances are that the problem is at the intake manifold gasket.

Mail.comI am leaking antifreeze. The Nissan dealer checked it and said it was the water pump. Where is the water pump located exactly? Thanks


The water pump is part of the timing belt assembly, on the front of the engine, so it is labor intensive to replace. Most will recommend you replace the timing belt, idler pulleys, timing belt tensioner and seals at the same time, so you don't have to do the job twice. Most reputable shops will always replace the water pump when they perform a timing belt replacement package, again so you don't have to do the job twice. Hope this helps. Have a nice weekend :O)

No spark While driving just shut down. Either backfired or sparked under vehicle twice. Replaced Microprocessor, egnition module and crank shaft probe F250 ford truck 350 engine, California specia 1983...


Tough to tell without being there but it may be your timing chain slipping or broken. At that age of vehicle (how many miles) if the timing chain has not been replaced - that would be my suspect.

I just replaced the timing chain set on this 02 Durango with 4.7. Now it is hard starting, jerks under load and sets codes 340 and 344. I didn't touch the cam sensor during the replacement. I know the...


You must have your distributor out one tooth. Or else the chain is out one tooth. When you aim a timing light at the mark, if the mark is jumping around, your chain is wrong.
If neither of those, then check your firing order, and make sure all the plug wires are on firmly, and are not damaged.

I have a 1993 jeep grand cherokee 4.0l and need a diagram for the timing chain links. i was told that there is to be 15 links between marks and then told 20. need help please.thanks


I don't have a diagram I can post, but once you install the new chain and have the two timing marks pointing toward each other, then turn the Crankshaft around twice and see if the two timing marks still line up. Remember, the crankshaft turns two times for every one time the camshaft turns.

I understand the 15 vs. 20, but that's neither here nor there. What the Factory Service Manual states is there should be 15 "pins" between the timing marks when the timing chain is set up properly. (?) The links you speak of aren't what you're counting...it's the pins in the chain. In other words, for each link of the Timing Chain, there are two pins, holding it in place...or a total of 48 pins on the length of the entire timing chain. Personally? When I install a timing chain, I rotate the crankshaft around twice to see if the timing marks still match up, and before putting everything back together, I start the Engine for a brief few seconds thereby knowing after reassembling everything, the Engine WILL Start.

If you're still concerned about the 15 pin thing, stop by your local Dealership and look in the Factory manual in Section 9 (Engine), Page 36 for a picture of the 15 so-called "chain-pins."

Hope this helps,

~00 Buck~

Do timimg chains need to be replaced (not a belt)?


Timing chains do need to be replaced but they can typically go much longer between being serviced than can timing belts. The chain will stretch out over time and can 'jump' timing. If you have an interference engine then that can prove disastrous as the piston can crash into the valves.

Its not terribly common for a timing chain to jump timing but not impossible. I have a vehicle with nearly 120k with a timing chain and its never been replaced and is still in good shape, I have another vehicle with 170k also with a timing chain that has never been replaced.

If it were me and I was going to be doing some work in that area and had easy enough access to the timing chain, and the mileage was getting up there, I would replace it. Timing chains typically also have a tensioner, so if you replace it, dont forget this item.
