commandosqueak Posted 23 October 2021 Report Posted 23 October 2021 So my car is currently on stands and the engine is being taken to bits. Finally found the culprit today! It wasn't the aircon like I first thought. Can you see the problem? Oh and its not the oil leak... and to those that already know please don't spoil it. No one has managed to work it out so far. I want to see if Actual Celica lovers can spot it.

CheltGirl Posted 23 October 2021 Report Posted 23 October 2021 No idea what's what on Gen 7's - but is the top belt off?
Old Red Celica Posted 23 October 2021 Report Posted 23 October 2021 Should that belt be going around the pulley on the right? 1
Jim881 Posted 24 October 2021 Report Posted 24 October 2021 (edited) I've seen it. Lools like whoever put it on missed out the ac compressor and went straight to the water pump. Still confused how it managed to fit properly. Edited 24 October 2021 by Jim881

Someone ordered the wrong part? Yeah I suppose if they ordered the first belt they came across and then just went f##k it and fitted it anyway. I can't see any other way unless there is some crazy routing going on. Would like to see if the rest is right.
commandosqueak Posted 24 October 2021 Author Report Posted 24 October 2021 nope there are two belt sizes. So the belt shredded on mine and I thought the AC was as fault cause every time i turned the AC on it would make a noise. The only spare belt i had available was an AC delete so put that on s I thought the AC was the issue anyway. Look at the crank pulley carefully... I have attached a picture of a new one. can you see the difference yet?
_Chris_ Posted 24 October 2021 Report Posted 24 October 2021 You've shown the back of the new one so I can't compare, but I'm guessing you have a misalignment (probably what shredded the belt) and it's down to the rubber for the dual mass pulley coming unstuck. If you've tried checking timing like this, it's probably miles out. Don't go for a solid pulley, as some do, or crank failure may well follow.
Old Red Celica Posted 24 October 2021 Report Posted 24 October 2021 The rubber bit does not seem to be attached to the central bit (hub)
commandosqueak Posted 24 October 2021 Author Report Posted 24 October 2021 you guys have got it... this is what has happened! Unfortunately this took out the Aux belt which mean no water pump, which means over heated and now means I'm stripping the engine to replace the head gasket!
_Chris_ Posted 25 October 2021 Report Posted 25 October 2021 It usually happens after using a normal puller tool which pulls on the outside. Should use a flywheel puller which bolts to the inside section
commandosqueak Posted 2 June 2023 Author Report Posted 2 June 2023 Well believe it or not the saga of this continues.... So as i said before i thought the aircon was the issue as i had a noise from it. well Found out the pulley was what caused the belt to go and me over heat. Sadly as I had to replace the head gasket and i had been driving it before i realised the gasket was gone the bottom end bearings were damaged. I have since pulled the sump off to look and the engine is toast. I have stripped the new parts i put on when i did the head gasket to use again in the future. timing chains are not cheap lol. I have a new engine to go in from the lads at SJ Autosports. Just got to put it in now. was hoping to have it running by the weekend but sadly the flywheel looks a little past it. so order more new parts... yay for credit cards. 2
slybunda Posted 21 June 2023 Report Posted 21 June 2023 Holy moly sounds costly. Do they still make new crank pulleys? If so how much, will remember to change mine if iv ever got it off.
Fuppylodders Posted 23 June 2023 Report Posted 23 June 2023 These cars certainly provide expensive lessons to us... At least you have a clear path ahead for progress now, fingers crossed no more issues!

If so how much, will remember to change mine if iv ever got it off. i got mine on ebay for about £200. brand new toyota one. otherwise i couldn't tell you if they are still available. As these engines are getting to 150k+ its def worth checking with routine maintenance. They are actually pretty simple to get off. there are 4 holes in the middle. two of the (opposites) are threaded. just thread in an appropriate size bolt. (about m8 i think) and just screw them in a couple turns each and it eventually pushes the pulley of. no special tools needed. I would run a tap in the threads first with some wd40 to make sure they are clean and easy to thread. i happened to snap a bolt in one of them. fortunately it was the old pulley off the new engine. I had put a new 200 pound pulley on the old engine... bet your ass i was transferring that over. Booked in for MOT on tuesday so i prey that it goes through. I dont know how much more public transport my body can take. I dont wanna know how much i spent getting this car back on the road... I know i still got stuff to do to it as well. wanna get a few bits of rust sorted underneath during the summer so its solid and protected come winter, also wanna cleanup and replace the bushes for the front and rear subframe and running gear. again probably a summer job that i will start saving for now ready to do when its needed. Will update the build thread at some point as i have fallen in love with he car again and got big plans.
