timing marks not aligned

[p.meaghan@ntlworld.com]

thanks all,
will sort that out tommorrow,now that i have some clarity it shouldn't be a problem.thanks again. "Dopey OP" (PAOLO)

Engine won't turn at all

well have tried to do what has been suggested however,
after aligning bottom pully and removing tensioner and belt.
i aligned the cam pully by going 1 tooth anti clockwise which meant all three marks were aligned.
i then re installed the belt both marks were aligned top and bottom,
tensioner back in keeping "long side" tight,
rechecked all marks still aligned then cranked over 1 full turn but half into the 2nd turn it stopped and will not crank any more.i am unable to crank over the engine at all,what do i do now?

If you have trouble getting marks to align and the crank is one tooth out, there's a simple solution. With cam at TDC have the crank one tooth before the timing mark. Fit belt to cam and then crank, turn crank a little to align. This works brilliantly on the 2.4 because of the short distance between pump and cam. No pump to drive on the 3Ltr but can also help with this side of belt. As Tony says this side of belt needs to be tight as the tensioner will not compensate if it's a tooth out.

Here's a good link with lots of pics of the 3Ltr.

Did mine for the 1st time last week took all of 30mins, the above pics came in very handy.

can you post up some pics of where you have aligned the cam and crank and does it feel like its knocking on something inside or has it just gone really tight?

Unless something jumped when you did the first revolution, it's not possible for the engine to suddenly jam on the second turn. I reckon your engine has bound its self up (pistons have hit the valves) at about 3/4 of a revolution.

What you have done is:
1 - timed the engine incorrectly.
2 - Kept the wrong side of the belt tensioned when you were timing it.
3 - Misunderstood what 2 engine revolutions is.
4 - Ignored all our advice and the instructions Nev posted.

Undo what you have done by turning the engine backwards by 1 1/2 crankshaft revolutions, then re-time it.

Yep you got it all wrong and have the crank and cam timing out which means a piston is on it's way up while valves are still open. Can be fixed with a bit of patience and thought.

Do what is suggested above and turn the crankshaft slowly and gently. You then need to turn the camshaft a little at a time, then crank, until there is no resistance and timing marks are aligned. Do this with belt off. Also remove rocker cover so you can see what the valves are doing. TDC on number one will be both valves closed and also the valves on number four will open and close slightly if the cam is rotated forward or backwards a little.

There's not an easier way to explain the above procedure. You just have to have a feel for doing it. There's been a few cases where I have had to fix timing, when this has happened.

did i ignore your advice?

I reaslse you asked Tony and not me, but I'll answer anyway.

The gist of what Muddle told you is correct, but I read what he was saying as being more relevant to a 2.4.

As I, Tony and Nev have said, all you have to do is line up the timing marks as close as you can, take the belt off, move whichever of the pulleys is out back in alignment, re-fit the belt (keeping the short edge tight), re-fit the tensioner, turn the engine (by hand) 2 complete revolutions (4 crankshaft revolutions) and re-check.

i did exactly what you said above,i cranked bottom pully till it aligned removed belt,turned cam anti clockwise 1 tooth(which you said was ok to do)i then reinstalled belt,oh and when i say"tensioner back in keeping "long side" tight" that was when installing the belt around both pully's,i then held the "short side" that goes over idler pully with a bungee to keep it tight as i installed the tensioner.then i attempted to turn the engine (by hand).

i did not ignore your advice at all. why would i?,just to lock my engine up.what would be the point of that?.i am not a mechanic,most of the people who use this site are not mechanics you say things like "just re-time the engine as if i know the correct proceedure to re-time an engine,if i knew such things changing a timing belt wouldn't be a problem.all of the non mechanics who value this site do so because of the invaluable knowledge and experience that can be found here and it is all greatly appreciated,however,some of the proceedures are sometimes grossley oversimplified so the poster doe's not look a 'newbie' and the importance of certain steps is not stressed enough resulting in small but important steps being missed,which is what started me on my current path.
losing patience with me because i don't understand what i have done wrong and assuming i ignored your advice just to do my own thing and posting said assumption is not fair at all.i am now in the position of potentially ruining the best car i have ever had(for no car is ever the same after surgery)due to my own ineptitude,i know this,you have no need to tell me.perhaps its time that a forum catagory for step by step proceedures be set up that are correct and irrefutable so that the confusion from multiple explanations is avoided.

I would suggest that you let somebody who knows what they are doing sort it out for you. Otherwise you could very well end up scrapping the engine.

i like optimists!

thanks for replying nifty,i applaud your optimism in me trying to sort this by your proceedure,but lets be realistic,completely detailed step by step proceedures are required for me to do this as working on the outside of the engine has obviously prooved to be challenging enough,looking at the inside would probably make my head explode as well as emptying my wallet more than its going to anyhow.cheers paolo

[NiftyNev]

Sorry, can't give you a step by step procedure for this. It's one of those things that I can't put into words.

You can't really do any damage if the timing is out turning by hand. Have a go at what I said and see what happens. It may take a while if you do not have an understanding of what is happening inside the engine. Just make sure you remove the rocker cover so you can see what valves on one and four are doing. One is front of engine and four is rear. I'm sure you can get it eventually. It's a bit tricky to do, so just just be gentle with it.

When you think it is right install the belt and turn by hand again to check everything is aligned and moves freely. If not sure, maybe someone near you can help. Bit far for me to come to the rescue.

hi nifty,
i shall give your suggestion some thought.my neighbour may be able to help,however i do think for piece of mind i shall have to take her to toyota to sort,as i am new to my area and have not had the need before and so i dont know(to have any trust in) an independant garage that i would feel comfortable giving the car to especially after i put my mits on her.i'm absolutly gutted ive had her since she was imported in 06 and shes only ever had 1 middle & 1 back exhaust and 1 set of brake pads.and i just bought 4 new tyres to replace the firestones it came over on.why oh why?

[yoshie]

Must be someone close who could spend the half hour needed to get this truck running again.

Stick a link in the general section, lots of these tech posts get missed by those like me who mainly post nonsense in general section but who could actually help you out.

[wishbone]

He's probably just met some compression when turning the crank.

Mine was going into Toyota to have it changed till i came across the pics afew posts up,they wanted £200 for a 30min job and it only takes another ten mins to reset the dashlight. Just take your time i am sure you will crack it

[Albannach]

half into the 2nd turn it stopped and will not crank any more.i am unable to crank over the engine at all,what do i do now?

I disagree.
