If only RB had done all similar jobs on the Stag. An excellent, hugely helpful and high quality video. I’ve watched and rewatched this countless times, just to be sure. Not sure I’d have had the courage without you. My nuts and bolts were no where near as compliant as yours, inevitably so my job took just a bit longer and involved a fair sprinkling of expletives too. Very many thanks. More please.

Very well done and I appreciate the information.Thank You.

It's such a simple and elegant engine design. You can see why it's worth persevering and not fitting some Rover boat anchor.

[@timothyrogstad5577]

Too right. This engine represents the end of "off the blueprint " engines from the British motor industry. And a thing of beauty it is. Imho

[@dennismfern]

Can you say why you have removed the dowels from your replacement tensioners.

[@RimmerBrosTV]

That's just the way they come from the manufacturer. You would have to ask them for a definitive reply, though they don't seem to deem them as necessary.

What a complicated design. What a palarva. Doing that while the engine is in place? Must take all day at least. And that is done every three to four years as well.

Whilst it can be a bit tight, any at home DIY mechanic with a workshop manual is able to complete this task with a little bit of determination and patience. The service intervals for this job are also much longer than 3-4 years as it is a timing chain and not a timing belt.

@@RimmerBrosTV Thx. The general recommendation is 30-40,000 miles to change the chain. OK it depends on your milage. Does the chain last longer when using semi or fully synthetic oil?

[@RimmerBrosTV]

@@johnburns4017 generally speaking the chain doesn’t need changing unless you notice symptoms of a bad chain/timing assembly such as rattling, clunking or general irregular sounds. Timing chains usually last the life time of the engine, it is more the tensioner’s and guides that wear but even then it is not a regular issue
