Hey shaz
Parts are not expensive it's the labour ahaha
Honestly if you can't do it yourself take it to toyota
I would never trust a mechanic with one of these cars.
Especially one who never has worked on one, timing belt can be done without engine out by mechanic who is experienced with twos
Toyota know what they are doing
We have two come in regularly
A yellow turbo one
And last Friday one like yours came in.
Your leak could be either
Rear main seal or a crank seal?
Or a tranny fluid leak?
If crank or rear main=expensive 6-800 buck job,
What colour is the oil?
20-50 is a but thick but if it is leaking engine oil I would stay with 20-50
I would buy your own synthetic oil however, and give it for them to use
Like penrite or nulon
Or if you want to spend big dollars Mobil one or royal purple.
Will run a lot smoother and extend oil changes.
Could well be a cam belt, but that's the same as a timing belt? Is it not a timing belt controls the timing of the cams?
Could be an ac belt.
Rattle could be rear bearings or ball joints.
Again not very expensive
Bring it to toyota for a check over then let me know what you need we will look after you.
