Pete Lewis Posted July 28, 2022 Report Share Posted July 28, 2022 is everyone getting soft , just crank the thing it will pick up and go as for the rattle they have been doing that for the past 50 years .............its a real problem even if you faf around with filters you cant stop the gallery and crank emptying by gravity Pete Link to comment Share on other sites More sharing options...
johny Posted July 28, 2022 Report Share Posted July 28, 2022 Its just so embarrassing Pete when you start and it rattles so everyone turns to look at the old banger thats on its last legs! Ive tried to explain that they all do that and its normal but then got all the opinions of worn bearings and oil pumps so I now prefer my spin and then start method (after replacing the bearings and oil pump of course)😁 Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 28, 2022 Report Share Posted July 28, 2022 aye what noise both mine had spin on's it does improve but i dont get paranoid about it ...........just be embarresed and smile back ha ! i guess the moderns do it but with better tolerances and cats pee oil you dont hear it Link to comment Share on other sites More sharing options...
johny Posted July 28, 2022 Report Share Posted July 28, 2022 tighter bearings and a new bigger oil pump definitely helped mine but it would have been interesting to know which had the greater effect.... Link to comment Share on other sites More sharing options...

I'm suffering start-up embarrassment and hoping someone out there can throw me an idea, or two. Mk2 GT6. My engine was rebuilt some 350 miles ago. It runs on unleaded, the ignition system is electronic, fuel pump and lines are new, tank has been cleaned and treated, carbs have been refurbished and the whole system has been rolling road tuned and from five seconds after start-up is actually 'awsome', as described by the rr tuner. It runs beautifully and sounds great but start-up is embarassing. On turning the key she initially sounds like she wants to start and then......nah! I've tried no choke, half choke full choke and back again and it's usually at least four or five attempts before she fires, at which point she says, come on lets do this, I was just teasing there. Is there a foolproof method to get her started please? Thanks Ian My vitesse did exactly this today. Started, fluffed then cranked forever with no start even after attempting to prime and turning it over for several five second cycles. The last time that I used it was before the heatwave. Inspection revealed just a small amount of fuel in the glass bowl pump and none showing in the filter at the top of the tank outlet. The pump does not like sucking vapour and priming achieved nothing. I had to fit my electric pump temporarily to the tank outlet and prime the whole line. All working fine after putting everything back. As Pete says, new fuel evaporates away faster than years ago and the extreme heat made matters worse. The sooner I replace the front to back steel with copper the better. I am pretty sure that some crud still resides in it. Of course it will rust if any of it is dry. Also agree with Pete over the rattles. My old Vitesse 6 did it every morning and was still going strong after 4 years. Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 28, 2022 Report Share Posted July 28, 2022 on H and V the biggest problem with priming is loose /air leaking in the short hose on the top of the tank out of sight out of mind Pete Link to comment Share on other sites More sharing options...
Wagger Posted July 28, 2022 Report Share Posted July 28, 2022 In spite of new hoses and clips this fuel seems to vapourise on vacuum. I have created a reservoir using a see through filter where the pipe leaves the boot so can now check it more easily. Link to comment Share on other sites More sharing options...
johny Posted July 28, 2022 Report Share Posted July 28, 2022 Also, even with empty line, a good mechanical pump should be able to pull the fuel out of the tank and over the high point especially if the tank is full... Link to comment Share on other sites More sharing options...

68vitesse Posted July 29, 2022 Report Share Posted July 29, 2022 My Vitesse rattles abit till it starts to warm up, piston slap?, but over a thousand miles to a pint of oil and reasonable oil pressure. Bought a spin on oil adaptor years ago but never fitted, my turn over and leave for a short while technique for cold start is more to preserve the battery. So to those who think it a problem 😀😀.

Chris A Posted July 29, 2022 Report Share Posted July 29, 2022 I don't think the rattle is a problem, just a quirk of the cars. It only lasts a couple of seconds, less than the time it takes to put on the seat belt. I would just advise not to immediately floor the pedal when you start up, as with any engine be kind until it is warm. After the first start of the day I don't get it again until the car has been left unused for several days. Link to comment Share on other sites More sharing options...

Wagger Posted July 29, 2022 Report Share Posted July 29, 2022 My problem is really 'bleedin' obvious. The line from back to front is original. The lowest point in the fuel system. Like any 'U' bend it silts up and there was never a filter at the tank outlet until I fitted one. If allowed to dry out, it will block partially, if not fully. Therefore, I will fit a length of annealed copper about 1/4 in bore as soon as I can crawl underneath it again. Link to comment Share on other sites More sharing options...
Pete Lewis Posted July 29, 2022 Report Share Posted July 29, 2022 its not piston slap that would be there all the time its purely the journal clearances allow the oil in the crank and gallery to drain into the sump the old style side mounted 6 cyl filer allows drain back to the sump as can some spin on's so when left for a period the oil pump has to refill all the losses and the bearings , big ends and mains give the unprotected rumble until pressure is achieved its done it ever since these cars wre built but as a daily driver it doesnt occur its the lay up thats the problem as said just dont rev it on initial start and it will last another 50 years the paranoia of filter drain back and pancake air filters just generate headaches heat ache and empty wallets for many owners who love to dabble . yes its just my views based on all the problems "must haves" make for us for the many .......do what Triumph designed and it will take you many thousands of miles with a smile Link to comment Share on other sites More sharing options...
Peter Truman Posted July 29, 2022 Report Share Posted July 29, 2022 Marcus (GT6) had an oil header tank solenoid controlled that opened and drained by gravity into the oil galleries when starting and isolated when when filled when the engine was running. He explained it last year we haven’t heard from him for quite a while, always enjoyed his input! Link to comment Share on other sites More sharing options...

Cant see that, if theres that much silt coming from somewhere surely it'll do the same with the new pipe. If its stuff already in the pipe then a blow through should save having to change it....

When I switch to 'Reserve' fine rust collects in the filter, so I change it every time I am stupid enough to have to use Reserve. Tesco filling station closed for maintenance so I had no choice last time out. Now carrying a can strapped in the boot. Second filter in the engine bay remains clean.

Wagger Posted July 29, 2022 Report Share Posted July 29, 2022 My first car had the SU electric pump in the boot. That kept the pipe clear by 'Force'. Maybe I'll fit a 1.4lb Huco in the boot as a backup. Once started, the siphon action continues and works until I leave the car fow more than a week. Probably should divide this post into two versions, one in Fuel, 'tother in 'Engine'. Link to comment Share on other sites More sharing options...

I think you must be missing the basic problem as Ive got a rusty tank but havent had to resort to any alternatives to the original mechanical pump with a filter before it. If the inlet pipe did empty (which it doesnt even after months) then I could just refil it with the pumps manual lever👍 Link to comment Share on other sites More sharing options...

Well that's one less thing to think or worry about, will have to find another one to keep the numbers up.
