Question.........is it possible to replace the timing chain without taking out the engine???

I would think you could, but what do you think.

Cheers

yes it is, the boys did it for Cherry on the weekend. Granted i dont really understand a lot of what they were doing so best to wait till TheMiniMan or NAV or someone equally as knowledgable posts in here

I don't see why it wouldn't be. I changed a crank pulley with the engine in the car. So it's just one more job to do after that.

But you'll have to remove the fan and radiator, and possibly more stuff.

Yep, I did it not long ago. There is a thread on here somewhere - with pics for proof.

It depends on your cam though. I have a totally stock cam in my car so the margin for error is quite high. If you have a high lift / long duration cam you are probably best pulling the engine out and using a degree wheel to make sure it is correctly lined up.

You'll have to remove the generator/altenator as well if you are going from simplex to duplex because you have to get backing plate countersunk.

The pics in my thread should give you a bit of an idea of what it all should look like.

It's certainly feasible doing it in the car. For me, I'd rather spend an hour pulling the engine to make the job easy rather than pulling it apart upside down with my head stuck down where the radiator goes.

Gettin rid of the rattles are we Rod??
Swap out the cam whilst you're at it. I've done that with the engine in situ as well.....

I have done it in the car, it isnt difficult.

But if time isnt of the essence I would pull the motor and do it all on the bench and save your back. It takes a little longer but the job is made much easier. Plus, you can fix any oil leaks that may have occured since it was last out.

Another advantage to doing it out of the car- you can time the cam in properly and use an offset key if necessary.
Not really enough room there to swing a degree wheel in situ.

Removing the engine only takes a few beers....

And while the engine is out you can clean and paint the engine bay and paint the engine.

G'day folks,

I have to take off the head too - #1has oil leaking in and it fouls up the plug after a couple of thousand Km's. I'm hoping that it's just a worn valve guide but that's a dead easy job. I've got another head in the garage just waiting to go. Changing the timing chain should be easy too. Got to get one or two prices of bits and bobs

Hooroo

All ready to go back together - then I was reading in a mag called 'Mini Expert - Issue 1 where he talks about changing to a duplex timing chain - the bit about altering the timing chain cover. Together with the pics from 1018cc's post earlier where he shows the alterations made to his cover using a Dremmel tool.

So if any one is going to do this, do exactly as 1018cc shows in his pic of the cover or you'll have to pull it off again.
