Doubt that, my car also threw an error code when the cam timing was out- TRC something (number) |

Engine light didn't come on even when it was really bad. The mechanic told me today its a possibility because he said he even had another mechanic shop cofirm timing. He said I should look at it from the side and not the top? Like as in my line of vision is in the wrong spot. I'm going to take it to a vacc registered workshop pay them $50 to confirm that its off or maybe tell me I'm wrong... |

Hi Scott,
If you get down as low as you can to the engine, even if its in front of the Bumper bar & look back at the Engine & timing marks on the cam gear & especially the rear mark on the cam gear, that's all your mechanic guy would do & if they definitely don't line up then it doesn't line up, sounds like your guy is not to keen to re-look at it ..
The VACC sounds like it might be the go, but leave off the covers if you can as that will save you some money in them pulling them off again,( your call ) did someone quote you $50 ?? |

Yeah about $50. My mechanic said he would do it and let me show him where it has to be. I guess if I agree to where it sits I can't complain that's it out. I'll have to take a day off work though. Won't happen this week. |

as previously advised, after releasing the tensioner, you MUST pull the engine around a couple of times and recheck the alignment of TDC and the 2 rotors. |

If it is still out that's an amazing / piss poor effort for a so called Mechanic & he should be so embarrassed ..
I would hate to see him do some multi cam V configuration engine running a four cam pulley set up, imagine how many owners would be coming back !! or how many valves bent .. |

The 1jz must be a walk in the park compared to the 1uz because I know they have done many of those. |

This time I'm going to just get it fixed but next time I will do it myself. Reading over the tutes gives me a fair idea. None of the tutes go into the detail of changing the cam and crank seal though. If someone in Vic, NSW or SA is due to do a timing belt on 1uz I'd be happy to sit in and help just for experience points. |

Scott, to change the crankshaft seal, I did this -
Strip front of engine down to to reveal crank seal located in oil pump.
Wind tape around crank near seal to prevent damage to crank where seal runs.
Make a small cut in seal from OD to ID, using a small screwdriver in cut, lever seal out, being careful not to damage crank where seal runs
I would guess same method could be used on cam seals
Hope this helps |

OK went to two different mechanics today and one said it looked 'pretty right' and that it is never 100%. Lol. Another said both sides are different. He thinks driver side is off 1 tooth. Interesting that one mechanic actually thinks its OK. Wouldn't take my car there either. |

I'm keen to tackle the job this wkend myself. There are some good tutes out there. Just a few pointers does the hydro pump need to be removed or can I just leave the fan hanging. Should I take radiator out? Does harmonic balancer need to come out and if so should I just use the breaker bar on the ground/starter motor method? Do I need any special tools? |

OD = outside diameter
I D = inside diameter
Thought it would be obvious |

Hi Scott, the dramas seems to continue !!
As discussed in the past if you get the Crankshaft timing marks to line up, then check on the Cam shaft timing marks, if its out one tooth that will equate to basically one tooth / lump on the Cam shaft pulley, you don't need to worry about the Crankshaft teeth now, just concentrate on the Cam shaft pulley ..
So to cover what I'm trying to say is if its out it will by one tooth or more it can be set up correctly, but if its a fraction of a tooth, then nothing can be done ..
So basically get down low to the front of the car as I mentioned before & look back at the motor & see how far the Cam shaft timing marks are out & if its out picture ( in your head etc ) the Cam shaft sprocket coming around 1 more tooth & does it align now ?? Using the white marks on the back cover & Cam shaft sprocket ..
Hope that makes sense .. |

Don't get how it could be out by half a tooth. It went into the shop with perfect timing pushing out 200rwkw and no mis fire anywhere. Now it doesn't pull the same and sometimes misfires or is jerky or hesitates. I'm almost certain its out and one mechanic agrees. Another just couldn't be bothered with it and didn't like that I wouldn't leave it with him for an hour or so. |

If the cam turns one tooth to the right then it will be sweet and I can get on with my life. Looking at the tute I understand most things accept removal of hydro pump and the pin on the tensioner. And how the tensioner works. Guessing it always wants to expand or push open?? |

As far as out by half a tooth or less can be due to belt stretch, not an issue in this case though as the belt is New & I have seen one manufacturer back in the early 80's had their timing marks out by half a tooth, not a common fault though, but from what I have seen with Toyota they don't fall into that category, they are spot on the marks ..
If you can turn the cam one tooth & it lines up then its definitely out & as you said makes me scratch my head too with that other mechanic's that looked at it & said it was sort of ok as One tooth out is definitely not right & Very noticeable too & No manufacturer is that poor in their markings ..
I think angle of sight is playing a role here, but as you have that rear cut out on the cam pulley to use to it should not be to big a factor ..

Explains why some mechanics say it doesn't have to be spot on. He really wasn't too interested and I think wanted to prove me wrong. |

Hi Scott, I changed the wording of my previous post a bit as I had a bit of a re-think, but to hear you say those Mechanics say it doesn't have to be spot on is Bullshit, out by a small fraction of a tooth is fine but not one tooth !!! |

OK the hydro pump is above the harmonic balancer and guessing I just unbolt it after I drain the lines?
I'm wondering with the tensioner I can. Just loosen the bolts enough to max out the travel on the tensioner leaving in still bolted on loosely. Move the can to the right a bit. Tighten the tensioner and check and recheck the cam position. I don't have to put a pin or Allen key or anything in the tensioner as I won't be using a vice to compress the tensioner. I will be using the bolts as they tighten up. Do I have a good understanding? |

Hi Scott,
Can't help you on the Hydro set up, either unbolt it or leave it there depending on how much of the covers you intend on leaving on ..
With the tensioner undone to the ends of the threads I'm sure the tensioner will still have to much tension on the belt for you to successfully remove & refit the belt & if you get the belt off the tensioner will just extend more so you wont be able to put the belt back on ..
As you are not changing the belt just moving the sprocket without moving much more than what you have done so far you might possibly get away with taking out the tensioner & trying to jump the belt over one tooth of the sprocket & if that doesn't work you could undo the camshaft sprocket & pull the pulley off & then slip the pulley back on without the belt & turn it then turn it one tooth & refit the belt, it may or may not work as sometimes the cams want to swing past the point but even with all the covers off it will still fight you .. then compress the tensioner & as someone mentioned a while ago try & refit it just to the point of the threads starting & then remove the holding pin & tighten the tensioner,( this way may work as far as the tensioner goes ?? & if it does it will save you a •••• load of time & effort as you don't have to pull off any other covers or possibly radiator etc too & if it doesn't work then revert back to pulling everything off .. |

OK fixed it myself. Nothing needs to come off at all. Just the bottom cover and with an extender bar and a half. Tried to leave the tensioner on the last threads but as I needed to loosen it more and more finally I got to the last thread. Finally enough slack in the belt to move the cam. When I went to move the cam the tensioner popped off. Spent a while looking for the bolts. So still got to put the covers back on but I went around 3 times and it lines up. Started it up and she is back boys. Good for another 100,000km. Thanks to me and the soarer central crew. I'm going to take it out and drop it on its balls later tonight. Its been too long... |
