The Triumph 2000/2500/2.5 Register Forum

Hi, I have a 2000 of the same age. I am sure that you will get lots of advice but my nylon fuel pipe is original. The big trouble are the rubber connecting ends which either go hard or perish and / or crack. I am pretty sure that these will need replacing. Most are accesible from the engine bay apar...

After fitting a 'proper' cap check out the breather pipe that should come out under the wheel arch (I think it is the same on the MkI). In the early days I had petrol starvation when the wheel arch got covered with mud and I have heard of people collapsing the fuel tank. I did manage to get an early...

Hello again. Yes that is what I thought I was looking for. But I take your point that you can't see any cracks going towards the centre. It was also suggested that you could get a view by taking the starter motor out. The noise seems to come more from the front of the engine and not the bell housing.

Hi Many thanks for your prompt reply. I did not drop the gearbox out but I checked very carefully every bolt by taking out one of the plastic bottom covers and checking with a lamp and inspection mirror as I rotated the engine and there were no signs of any disturbance. Will this be enough?

Hi Everyone and hopefully a Happy New Year! My 1970 2000 MkII Auto has developed an engine knock over the last two years. This happens until the engine has got really warm and also if pressed hard such as put into kickdown. Now the oil pressure is over 80 psi and drops down to about 50 psi on idling...

Just an update - I have taken the head off and looked at it. No sticking valves. Very coked up. All exhaust valves pitted but not burnt through. One valve seat looks as if it has recessed as there is an extra 0.5 mm 'ring' around the taper and on another cylinder there is barely 1 mm between the inl...

Many thanks for all your help. I'll get the head converted to lead free and then investigate the engine further so it may be some time before I come up with a result but I promise I will post the outcome here eventually.

Just for clarification the oil pressure was high and the noise was much higher pitched or 'sharpish' than a big end problem; could it be a seized gudgeon pin?

Hi, I started the MkII 2000 just before Christmas after a rest of about three months due to other reasons. I wouldn't normally go this long between periods of use. A series of loud banging noises came from the engine. I didn't run it for long. I suspected that I had dropped a valve, broken a valve s...

Having had one piston in the rear brake cylinders seize up yet again I was wondering if ther was any approved lubricant to use on the cylinder under the rubber cover. I can't find any mention in the the manual. Can you still get the castrol red rubber grease and should you use that as other lubrican...
