Corsa rattle?
« on: 16 March 2011, 20:12:27 »
Got a 53 Corsa 1.0, 3 cyl jobby. Seems to have a rattle for 3-4 seconds on the first start of the day, I'm thinking the hydraulic chain tensioner is filling up, any ideas why this would be draining? oil is up to the level and once started it runs sweet all day.

I know the chains can stretch on these but think this one is ok, any helpful tips or experience of these?

Yeh, timing chain, not hard to do and is a classic symptom of poor servicing.

I was about to say it's had seven main dealer services but these days that means naff all ;D, 70k on it.

Never done a chain before but willing to give it a go, anyone got a decent guide?

you need a locking pin and a tool for holding the cams in place but ive done them without em.just make sure you mark cams with tipex or a spot of paint.ive just done the belt on my elite and v6 calibra without locking tools and both spot on.paul :)

The cam tool is nothing more than a bar of metal (so easily made) and instead of pins, the correct size drill bits do the same job.

Without the timing horseshoe, you cannot tell.  In fact, without the crank lock, you can't even tell that is spot on ;)

You can make some kind of estimate using the (desperately inaccurate) case markings - this will ensure its no more than 1 tooth, possibly 2 teeth, out - which is OK (just!) in an emergency, but really needs to be set properly at the first opportunity :)
