That horrible noise when a cambelt snaps
Discussion
Hi all
I was in my off road toy Discovery 200TDi today, when i heard that inevitable crack as the cambelt snapped. Took oil cap off, cranked it and no cam turning.
So, how terminal is it on 200 TDi engine? Also, if you are reading this and you are in the midlands, have a read of this and please come and help!!

Not very - you'll probably have to replace 5 pushrods, but that should be it. (Plus the belt, obv!)
ETA: On the 200 TDi the pistons hit the valves squarely, so the damage isn't usually too serious. Roll the pushrods around on a flat surface to find the bent ones.

Therein lies the problem. Not sure I have the ability to strip it down and figure out what's going on. I'm going to have a go, but would feel significantly more confident if I had some expert help.

Do you think you can do the cambelt change? The only bits that I'd be worried about would be the water pump bolts breaking and whether the crankshaft pulley would come off easily. As long as you can afford to take your time it shouldn't be too bad.
The bent pushrods shouldn't be too hard to sort either - remove the rocker cover, slacken off the adjusters, remove the rocker shaft and pull them out of their holes.

There's the rub to be honest. I've never done a belt before. Done oil changes, brake changes and a couple of suspension jobs and that's about it! Will be stripping it down and having a good look tomorrow, fingers crossed I will get on ok using combo of internet and haynes, no confidence at all thought!

Good stuff.
Spend some time amassing all the bits you need before getting too far into it - you might have to hunt around a bit for one of those bendy torque wrenches, and probably best to order all the bits on-line because it's doubtful whether an ordinary motor factor will carry them. (In fact, they won't). One tip - careful as you do the rocker cover bolts up because they are very weak and the heads shear off very easily.

Beauty is the Landy is my 2nd car, for off road use only. So I can take my time, find out what needs replacing, then order what I can't get from local supplier. Bendy torque wrench will be fun I'm sure. It does worry me I don't really know what i'm doing, but what's the worst that can happen?!

The worst? The engine won't work, so, you will find out why.That's how we learn, don't accept that you can't do it.
There are now so many avenues of help, this medium now being the primary one, that if you have the determination, you will be able.
Find out, take it slowly, check and recheck, that's the way.

I had the same happen on my 200 Defendere recently. I removed the rocker cover, removed the cam shaft and replaced all 8 pushrods (£20 ish for all 8). I was lucky that no rockers broke .When you take the cam shaft out, put the bolts bacl through the holes first otherwise it will all spring apart!!! The timing belt is fairly easy but make sure you read the Haynes carefully first to set up the timing of the crank (slot in the underside of the flywheel), fuel pump (drill bit through slot) and cam (TDC mark on pulley). The only difficult ting will be remeving the bottom pulley - and ignore the advixe of 'low ratio first gear' and use high ratio 5th gear!! This will stop the engine turning.
If in doubt, look for your local Landy club and see if anyone can help.

Thanks for the advice. Fortunately, I got it to pieces yesterday. It was a case of all ancillaries off, pop the push rod's out (4 from 8 bent), then whip the rad out and buy some help from a mate over the road, who came to my aid in a works van with a gun and compressor to get crank bolt off, only cost me a 4-pack too!.When you take the cam shaft out, put the bolts bacl through the holes first otherwise it will all spring apart!!!

Parts bought from Paddocks today, so now just gotta get it all back together!!
