  1. Hi Paul

    From your description of when you changed down a gear to second, it sounds very similar to when you try to change gear without using your clutch. The gear will pop in when the engine revs match the gearbox gear. This would I guess point to a problem with your hydraulics not operating your clutch. Slave cylinder/Master cylinder or plastic pipe. Bearing in mind the amount of effort you have put in so far I would replace the lot.

    Best of luck

  2. Hi Dave

    I found the following on the AA site which might help. I would check the age of the tyres as you might have been sold old tyres. It doesn't sound as though they have been damaged by Sun light as the cracking is on the inside of the tyre. I would stand firm and expect them to replace them as they are not that old. Have you been in touch with the seller.

    Best of luck

  3. I read a good tip on the Forum to fill up the O/D, which was to jack up the front and then fill the gearbox with a bit more oil than the capacity.  Leave overnight then drop the car down in the morning and with a bit of luck it should overflow a  little bit. If not top up.

  4. Hi Colin

    I have dismantled the injectors quite a few times and replacing the o rings is quite easy after you have done it few times.  Be careful when taking off the metal retaining ring & do it in a plasic bag if your worried.  I use a piece of wood to press out the inside ,shaped like a round pencil. Use a bit of vasaline when putting on the o ring and re assembling as there is a ridge in the bore of the injector, to avoid damage. I  then use a tyre pump with a inflatable bed adapter which is coned shaped to check that injector is popping off of at about 50/55 psi. Easy to adjust.

    Good luck  Roger

  5. Hi Pete

    Unfortunately there is no one tool to deal with removing old underseal from my experience.  I have been working through this horrible job over two winters and have still not finished although I have taken it at a  leisurely pace. I have found if the underseal is really old and dryed out a selection of old  wood chisels can scrape it of  quickly followed up with a rotary wire brush on the end of a drill with white spirit liberally brushed on wiil remove the remaining underseal.  More recent underseal is best removed with a heat gun and stiff scraper followed up by white spirit and rotary wire brush and drill.  For removing paint/rust and any remaining underseal various wire wheels and nylon abrasive wheels either on a drill or angle grinder work really well. Good luck you will get a lot of satisfaction when you are finished.

  6. Graham Thanks for your info and I will check whether the caps are alloy or not.  I don't think they will be as the engine was rebuilt in 1989 and has done around 40,000 miles since.

    I think you are right it is probably a sticky valve.  I am a bit worried that if it happens again at higher RPM that it will wreck the engine. There was a lot of oil around when I took  the cover off and the tappet was moving smoothly in bore.  I think I will assemble the push rod and then take out the spark plugs and turn over the engine to check that the valve is not seized. If ok I will do as you say Waldi then run the engine to check that its oiling properly.

    Many thanks I will let you know how it goes.

  7. Looking for help please as I have never experienced the above before in spite of driving some really old cars with worn out engines in the early seventies. I have just taken out my TR6 1975 CR to the bottle bank for the first time this year approx one mile and on the return journey and almost immediately I notice the engine was misfiring a bit( not unusual for the first journey of the year). Then I noticed a rattle from the engine above 1000 RPM. Stopped immediately had a looking thinking I had left something under the bonnet, but no such luck the noise was coming from under the rocker cover.

    I limped home keeping the revs below 1000rpm avoiding any tapping. On investigation at first I couldn’t see anything wrong after taking the Rocker cover off. Then I noticed that the inlet valve push rod on cylinder No 1 was disconnected from the rocker and resting on the next push rod cylinder no 2 which must have been the source of the tapping. The only work I carried on the engine apart from changing the oil and filter this year has been adjusting the tappets. I am pretty sure I adjusted it correctly as I always do them twice.

    Ok so on a quick inspection there seems to be no damage to the push rod it looks straight and the cup and ball ends look fine. The rocker appears to have no wear and  the adjuster and nut are not loose. Has anybody experienced this before and what the likely cause is. My hunch(hoping) is that I haven’t adjusted the tappet correctly although there was no loud tappet noise during the first part of the journey.

    I have partially lifted the tappet using the push rod by suction and it seems to lift smoothly and nothing seems to have broken off it. Should I take it out to inspect and if so suggestion on the best way to do it would be great.

    Any ideas  on what I should do. I am leaning towards having a look at the Tappet if I can and if ok reassemble the push  rod and see what happens.
