  1. Me again, Bob, you said... 'There are open vents on the top of rocker arms and the brass attachment for the front drain tube ' Well the front drain tube is clear and fine, but when we look down through the hole in the head, there is a step there that looks like a misalignment between head and block....its very odd! However I dont think its restricting flow.....'open vents on the top of the rocker arms'....we only have a vent in the brass fitting at the end. There is another hole that has a plug in it which is the first mounting point back from the front end. S
  2. Gentlemen, I am new to this section of the forum but am after some help. I am the guardian of a 1912 but 1913 model year car which belonged to my father who passed away a few years ago. On starting the car at the weekend I managed to blow out one of the caps in the cylinder head holding the spark plug. It was terrifying and with the hood open the 1lb chunk of metal flew into the air and didnt come down for several seconds, Smashing back into the front wing! Ok, I remember about twenty years ago the same thing happened. I have also found brand new replacement
  3. Good morning, Well we've had another go at it....we have put a sleeve into the oil feed pipe to the rocker shaft to try to reduce the flow of oil. When measuring the output into a cup however, it seemed to fill in exactly the same time! But, the breather hole at the front of the shaft (at the top of the overflow feed to the timing gear) is now not leaking oil, so some volume must have been stemmed. Also the oil presure has gone up from 15psi to 22 psi. Although I dont know how accurate the gauge is... Lastly while we were doing that, w topped up with some straight 50 oil,
  4. Bob, once again, thanks for your help https://photos.google.com/share/AF1QipNJ4YEm9II24DJC0rCVsHBTumRIC9Yp3vD9p2w4o0bABwslvEt3Ur1_8MuRfkXcDg?key=NU5DOWZlaTdFYWFiNzdqUHQ0SUg1X0x3dmNsbHl3 Have a click on this link and look art the volume of oil dripping from the underside of the rear of the shaft....this happens in a few spots. It looks a lot of oil! https://photos.google.com/share/AF1QipMQec20PkKHDYlJih0gjONZNfor8fME5NHPMQ1aZ7iUqObI12se_3OMAPnAvMAOsw?key=TWZPTlJxSXRPcy1HMmRjM2RmWkY1aVFublY4dGl3 and this one too...hover over the image for movement.
  5. Bob, thanks for that..do you notice my oil feed in the rocker area? The first piece of pipe out of the head is smaller and is soldered to a bigger diameter tube. It looks like a mod, so do you know which diameter is corrrect? Also , and this is killing u, do you know the thread into the head where the pipe is, and also the thread the other end, feeding the rockers. Regards Simon
  6. Bob, I hope you are out there... here red are two photos....the first one shows the red oil filter housing them a pipe up to the gauge and the other that I believe feeds the head.....the second shows the oil pipe to the rockers etc. these are both 7 MM. So is that 5/16's or maybe 1/4. Are these the pipe you referred to earlier? At the front the pipe back into the head is 10 mm i would be really grateful for your opinion here regards simon
  7. Gentlemen, As an update, I have now fitted a Stromberg 97, which was relatively straightforward. On top of that we have fixed a charging issue and replaced a faulty fan contoller...it seems there is always a list of stuff that needs doing! Anyway, its early days, still shaking down the carb, and I've only done a handful of miles, but the results seem very good. Easy to set up, more power, no choke needed (except for starting) smooth acceleration, big decrease in smoke from the exhaust. I'm hopefully going to give it a longer run over the weekend an see where we are
  8. But also mean I needed to run with a lot of choke to get a mixture that would burn... So I have a fix involving a stromberg. I'm going to try that and see how it runs. Then maybe I'll be able to put some proper miles on her and shake the rest down
  9. I think I may have found the problem......... I finally took i all to bits and found a chunk of the casting held on by sealant, which had been painted over! Do you think this would impair running? Looks like plan B simon
  10. New Champion D16's fitted today.. Breather pipe removed and inspected. This just has baffles in it and thats all ok....how do I find the other screen? It did start well and the choke was turned off pretty quick even though I was only running it in the garage...
  11. Bob, The heat riser is not connecting the carb to the exhaust. To my knowledge its never been present. I've done 35 miles in her today and I've been out on about five short trips over the last two weeks, trying stuff out. I do think she has improved. I drove today with no choke on!!! Still got smoke though. Had her up to neary 60 mph in one burst just to see if the carb spat etc but she was fine. I do have a low speed front wobble now, but I put some more air in the tyres to lighten the steering so it could be that. the plugs were all wet and black when I took the
  12. Thanks for all your replies. Bob, those last two are the kind of things I suspect are causing me a problem as everything else seems relativly ok.... What do you think to the compression test results? Simon
  13. Gentlemen, Its been a long time since I was on....other cars to play with! Meanwhile back on the Buick, I still have a lot of blue smoke. I have just checked the compression and I have 6 cylinders at 100psi (as close as we can read), number 2 at 90 and number 3 at 95. I'm not sure what they are supposed to be, but that seems fairly close. I still think I have carb issues, it seems to need a lot of choke for a fair few miles, and nearly always needs some choke on. We bought and fitted a repair kit, but have never worked on a Marvel before so we cant be sure of what we've d
  14. Thanks very much for your comments....In that case what would be the coerrect compression to have, and what sort of tolerance is acceptable? Thanks
  15. Gentlemen, my series 50 is puffing a deal of black smoke and I'm getting to the stage of having to face a pistons and rings type job. Can anyone help me with whats available in that area, also problems to expect, liners, dimensions etc Thanks Simon
