preventive car care
|
|
|
gearheads.....the car is a toyota 22re......i gave it a try to look down the the top of the engine at the cam gear with a light to see if i could get a look at the upper driver side chain guide and bolt for any signs, L/R timing chain guides and maybe the tensioner if possible before it fails.
i could see down a little but not real good.
any suggestions how to get a look down the front to get a look at the chain guides and tensioner?
is there a camera for this to go down the timing case to get a look?
thanks.

You can't tell anything that way. You need to know how much play is in the chain and you can't do it that way. If you're hearing ay rattling coming from that area, it's probably time.

Why are you looking for a problem if you have no symptoms?

You haven't even said what model year or I missed it. Timing light not the right tool for testing this. If anything and right there look, feel for slop and maybe turn crank bolt to watch it move back and forth and probably nothing so forget it till you do notice something.
Nice to prevent a problem if something seen but seems nothing is wrong right now,

No info on how many miles on this chain either.

I wouldn't trust a timing light to tell if you have a stretched chain or guides. Someone could have moved the distributor or any number of things, beside a stretched chain, can cause timing changes.
If it isn't making noise, your probably ok. Those little engines are pretty tough.
If anything and right there look, feel for slop and maybe turn crank bolt to watch it move back and forth and probably nothing so forget it till you do notice something.
That engine is OHC and the chain tensioner is pressured by the oiling system. What ever wear, up to a certain point, the tensioner will take up the slop. You can't determine chain stretch on those unless you measure the chain with it in your hands. If you turn the crank back and forth you'll push the tensioner back and you will end up with slop. You shouldn't spin that engine backwards anyway.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

tom>>>>>You haven't even said what model year or I missed it. Timing light not the right tool for testing this.<<<<<<
chuck>>>>>its a 94 22re.....were they not all the same from about 84 to 94 or 95 when the 22re was discontinued with the new Tacoma model?...i know a timing light is not the right or best tool for this but its all i have.....i was wondering if the strobe light on the crank timing marks would show any slop or wear in the chain, guides and tensioner.
Hammer>>>>>No info on how many miles on this chain either.
chuck>>>>>i dunno.....its a 94 toyota 22re....speedo says 144000.....its probably not the original..... it was probably changed at sometime but i dunno.....at 144000 it might time to get a look but i dont want to take it apart. Its a lot of work to remove and install the cover on a 22re.
what if i go on a trip or way out of town maybe hundreds of miles from home. This is not exactly something that can be done at the side of the road. I wont have the tools needed to do this. I only carry a basic toolbox behind the seat. So i guess pay $600 to have a mechanic fix it and stay in a motel or drive it home with the chain grinding on the cover and maybe destroy it. Now i need to buy a new cover. Maybe even jump timing and get the infamous valve interference if this engine has that possibility. Just trying to catch it now while im in there. Thanks guys for your help....
Q.....i guess a timing light wont work.....Is it possible the wear will show while i move the crank in reverse directions while looking down its throat from the cam gear with a my 1/2drive ratchet and i think its a 19mm socket?
thanks guys for your help.....i was just wondering if there was a way to diagnose a worn timing chain, guides and tensioner......

I have a feeling that you should just go ahead and do a timing chain service. If not, you'll be worrying about it the whole entire time your driving on your trip. You'll have a miserable time.
I'm a mechanic and when I drive on long trips I think about all the things that could go wrong, especially on something old with many miles, so I know where your coming from. If you feel that something isn't right or it is on your mind all the time, just fix it and give yourself peace of mind.

yeah D, i was thinkin the same. Its old..... open it up, do the fix or leave it alone and don't go too far..... i dunno if i would want to take a chance because of the age of the car and not knowing when the chain was done last.....
here's why.....
It failed the visual smog test. I had tear it down to fix the broken timing mark on the oil pump between the timing case and the harmonic balancer. The timing mark is part of the casting on the oil pump.....i replaced the oil pump and the harmonic balancer.....requires a tear down to the timing cover....Thats why im in there and looking around at the timing chain.....

I owned a 22RE in a Celica years ago and when the chains get worn in those they start rattling like hell, only on start up in the beginning and all the time when it gets really worn. When it gets really worn it will start hitting the timing cover and eventually will wear right through it letting coolant into the oil but it will make a lot of noise in the meantime..

One thing I have learned over the years regarding preventive car care is to keep up with my vehicles maintenance schedule. I use a product link deleted ...... not allowed that was recommended to me by my mechanic. Basically it tracks your maintenance schedule and reminds you when anything is due. I have 2 older vehicles both with over 100 K and believe me its already saved my money on repairs. It reminded me to change my timing belt on my Amigo at 150K. When I took it to my mechanic he said the belt was about to break which could have cost me a new engine.
