It's not a nice job, I don't enjoy doing them.

The engine can be raised lowered using a trolley Jack and a piece of wood (carefully it's a tin sump)

I usually replace the high pressure pump to block gasket if any signs of leaking when stripped also. But yes replace all gaskets and seals, why you wouldn't is beyond me!

my advice to anyone keeping the car or for anyone who cares,buy a chain casseste rather than the belt!

 

its a straight swap if its being done anyway,no mods needed

 

So you guys are talking about the 1.8?

 

The first post of this thread also covers the PSA 2.0. Are people still finding the link between the two cams is failing? (chain/cogs)

Are there any similar upgrades to make the 2.0 more durable?

 

Timing belt kit including water pump for 2.0 tdci in Australia at Ford dealer with no trade discount was $1178 (548 UK pounds) for parts only when I enquired recently. Seals gaskets extra. Interesting were the engine oil remarks in the video. I had a Falcon that did over 500,000km on the same transmission oil and timing chain. Admittedly the head gasket blew twice.

 

I wonder if timing belt failures are really an issue. ATM I'm going for the 200,000km/10 year option as specified in the owner's service manual. Even though I'm using the 'wrong' oil i.e. Nulong long life diesel oil ACEA A3. It has been suggested that long periods of idling might not be good for cam belts.

 

Does anyone know if chains are available for the 2.0?  I'm guessing not, given the difference in tensioning arrangements.

Any cam link chain failures?

Thanks for the answers, what happens if i don't change now lower belt tensioner at all and it brakes down later? Lower belt jumps over (and breaks engine)?

 

I was thinking to keep car to 250k mileage.

Agreed losing the tensioner throws the timing, your looking at bent valves, blown seals, piston and cylinder damage. Best to replace everything in one go. Admittedly I did not replace the water pump with the timing belt, this was due to a lack of money, but it's worth spending the money on.

It makes a nasty mess, I have pictures somewhere of one I stripped a while back. Destroys cylinder head, valves and Pistons.
