Lots of Noise on start up

[magic magenta]

hi

Got my new stag on the road, this is the first stag i have had with the Triumph engine in,as my other one has the Rover SD1 in her.

Should there be a bag of spanners noise when it first starts up? it is only for a second or two, should i be looking for a problem or is this standard with this motor?



thanks Martin (the only owner on the island)

Martin, the stag engine actually sounds smoother than the Rover engine so you may well have a problem, maybe the chain is on the way out

Mine sounds like a bag of spanners.. but the 12-15psi oil pressure when hot is probably something to do with it.

If it's a 'tappety' spanner-y noise, you have some adjustment under the rocker covers to do!

Hi Ted

you can call another member anything you like on this forum and we can even forgive certain tea partys, but don't diss the covers, they are 'cam covers'

Martin.

Sounds like the timing chains, they rattle when warn until the tensioners take up the slack, as the oil pressure builds up.

Tony Hart made a good video of how to change the chains.

Hi Martin If its a noise like all the tappets rattling for a couple of moments immediately on start up from cold its almost certainly worn timing chains DONT drive it beceause if the chains are badly streched they can jump off the sprockets causing terminal damage. Chains should be replaced every 30000 miles or sooner if there is any doubt. I think the jury is still out on whether you replace with Germanwhich dont stretch but have been known to break or UK manufacture whish just seem to stretch but at least you get the warning so long as you heed the warning rattle They are not difficult to replace if you follow the manual

Good luck Tony

Thank you all for the replys.

I will change the timing chains , is it a good idea to change the sprockets at the same time?

While you've got the front of might as well, I did the cam and crank shaft sprocketsonmine.

Hi Martin Yes its a good idea to change the sprockets at the same time as worn sprockets will accelerate the wear on the new chain .Whilst you have the front end stripped down you might consider pulling the Jack shaft out for a check . I know its more work but a Jack shaft failure is also fatal usualy resulting in a total strip and rebuild of the entile engine . Don't forget to replace the jackshaft sprocket any way

I would suggest before you start chucking cash and time at the engine that you youtube thebag of spannersand get a more accurate assessment of the noise....

I've always called them rocker covers.. I grew up in sunny Brighton in the '80s and the Dolomite's rocker cover was frequently off.

Over here in backwardsland, the "rocker" is a term for the front wings.. work that out then!

Mine sounds 'rough' when starting, but its while the starter motor is engaging, not the actual engine.

Happened since fitting a new starter (actually fitted two because the 'noise' sounded bad, but it did it on both). Soon as the engine fires and I disengage the starter, all is well again.

Actually turns out that I had a Rover SD1 starter in my Triumph, which apparently do fit (and are smaller). The 'proper' Triumph starter made an awful sound when engaging, so I went back to another Rover starter which although loud, seems to work okay with no grief in 6 months of use...

If you are getting your 'spanners' while the starter is spinning, it may just be where the starter is engaging?
