Joris Posted July 17, 2007 Share Posted July 17, 2007 Let us know where you are, I can't help you since I'm technically inept but I'm sure there are people here who can offer you advice. Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted July 17, 2007 Share Posted July 17, 2007 Hi Tony, You might want to look at the dedicated WW2 Dodge site http://forum.ww2dodge.com/viewforum.php?f=5&sid=b7b723e9dd2c643d941fb68e611bda12 There's quite a bit of detail there. I've got my WC 52/55 motor out at the moment - it had a collapsed piston. I've had it rebored/ crank re-ground and am fitting new pistons (+.020), rings, big end and main bearings etc. It'll go back into the vehicle shortly. Can you provide a little more detail on your problem and what has been done to the engine that might contribute to your difficulties ? It's a little hard to make any sort of intelligent diagnosis at the moment. Jack Quote Link to comment Share on other sites More sharing options...
Tony Pearson Posted July 17, 2007 Author Share Posted July 17, 2007 Sorry maybe did not put much information on as i should im in south yorkshire/lincolnshire area. What have done so far well replaced all electrics eg distributor cap points etc new leads plugs, rebuilt carb, replaced all gaskets eg head gasket exhaust inlet etc. ran head gasket leak test came back fine. Basicly its runs rough and throws out a lot of white smoke going grey when you rev it. Any help would be great. Thanks tony Quote Link to comment Share on other sites More sharing options...
Nick Johns Posted July 17, 2007 Share Posted July 17, 2007 Have you tried running it for a while on a separate fresh fuel supply, other than the fuel tank, any diesel fuel in it?? .....jerrycan of petrol and bit of pipe connected into the pump while acertain if its fuel contamintion Quote Link to comment Share on other sites More sharing options...
Tony B Posted July 17, 2007 Share Posted July 17, 2007 Sounds like a very bad case of the Dodge Cough. what Carburetor have you and what timing have you got her on. Also post the problem on http://forum.ww2dodge.com/ Might well be the accelerator pump. Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted July 17, 2007 Share Posted July 17, 2007 ... ran head gasket leak test came back fine. Basicly its runs rough and throws out a lot of white smoke going grey when you rev it. Tony, White (tending blue) smoke makes me think that your rings may not be the best. Have you done a compression test - apart from your 'head gasket leak test' ? As said above /\ it may be old fuel. Have you checked your inlet/exhaust valve gaps ? The missing could also be due to a burnt valve, but a compression test should narrow that down. I know how frustrating these things can be but keep at it and we'll find the problem. Jack Quote Link to comment Share on other sites More sharing options...
Tony Pearson Posted July 26, 2007 Author Share Posted July 26, 2007 Thanks for all your help will get on trying a few of your suggestions and feed back what i find and hopefully will get there soon Quote Link to comment Share on other sites More sharing options...
ArtistsRifles Posted July 26, 2007 Share Posted July 26, 2007 What does the smoke smell off?? White smoke can also be coolant. Is either the rad pressurizing or are you gettiting contamination in the oil to indicate the two are mixing somewhere??? Alternatively - as Paul found out with his Pig at Beltring - it can also be an indication of brake fluid getting in via a duff servo.......

Tony B Posted July 26, 2007 Share Posted July 26, 2007 That one on brake fluid is a new one on me. Not a problem with Dodges, brake assistance is a heavier boot. What type of carb do you have, and are the valves adjusted correctly? Quote Link to comment Share on other sites More sharing options...
Tony Pearson Posted August 8, 2007 Author Share Posted August 8, 2007 Right got a bit more on testing out some of your ideas but thing get stanger. ran a compresion test and all coming out between 8-9 Bar which is ok buy my manual. checked spark again and got a good spark but now wont fire up at all and now seems not to be getting nay fuel i have stripped doen the carb but all seems fine no sticking float or anything. What i habe found now that after turning it over for a while that there is fuel coming out of the pipe that goes from the inlet manifold to th block ( no idea what this dose). Any more suggestions would be greatly taken dont know if to try a new carb. :? :? :? :? Quote Link to comment Share on other sites More sharing options...
Tony B Posted August 8, 2007 Share Posted August 8, 2007 Right two possibles, the fuel pump itself, there are 2 types and a collapsed fuel pipe. Try feeding fuel direct from a can. another odd silly one, loosen the fuel filler cap, it may not be breathing properly. Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted August 9, 2007 Share Posted August 9, 2007 Tony P, Not sure what you mean by the "... pipe that goes from the inlet manifold to the block". Any chance of a picture ? Jack Quote Link to comment Share on other sites More sharing options...
Tony Pearson Posted August 9, 2007 Author Share Posted August 9, 2007 Its the solid steel pipe leaves the botton on the inlet manifold and gose to the side of the block in like a round conection on its side. Hope i make sense Quote Link to comment Share on other sites More sharing options...
Nick Johns Posted August 9, 2007 Share Posted August 9, 2007 That pipe is the crankcase breather pipe, ... Just a thought have you checked the oil level, is it overfilled?... had this with a Jeep recently that blew out clouds of smoke, the level was several inches too high with oilly petrol owing to a faulty fuel pump diaphragm leaking petrol into the sump, it was then being sucked through the crankcase breather into the inlet manifold !!

Tony Pearson Posted August 10, 2007 Author Share Posted August 10, 2007 yes oil levels are fine not sure why fuel would come out of there and none get to plugs Quote Link to comment Share on other sites More sharing options...
Tony B Posted August 10, 2007 Share Posted August 10, 2007 Have you got vacuum windscreen wipers on it? Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted August 11, 2007 Share Posted August 11, 2007 Surprisingly, I don't have a pipe coming out of the bottom of my inlet manifold and making its way to the crankcase breather. Wonder why not ? The only pipe going anywhere from my manifolds, is the one to the vacuum wipers. My sump breathes through the oil filler tube. Sorry, I can't put up a pic as my motor is still out - should go back in tomorrow. Anyway, I suspect that if you have fuel dribbling out of this pipe , your carby is flooding, or at the very least, providing too rich a mixture to the cylinders.

Tony Pearson Posted August 11, 2007 Author Share Posted August 11, 2007 Yes i do have vacuum wipers on the truck Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted August 11, 2007 Share Posted August 11, 2007 Tony, What do the business ends of your spark plugs look like ? I know you have replaced the points, so they should be OK. Are you sure you have the plug leads in the correct order ? Jack Quote Link to comment Share on other sites More sharing options...
Tony Pearson Posted August 11, 2007 Author Share Posted August 11, 2007 Plugs are new to they look ok and checked firing order thats good to. Now took off carb going to stip that doen and see if i can find anything Quote Link to comment Share on other sites More sharing options...
Tony B Posted August 11, 2007 Share Posted August 11, 2007 Check the seals on the wiper vacum tube. It can cause all sorts of weird and wonderful problems. http://forum.ww2dodge.com/index.php this is the specialist forum. Quote Link to comment Share on other sites More sharing options...
mazungumagic Posted August 12, 2007 Share Posted August 12, 2007 Tony, Unless the problem is something really unexpected, like one of your newly installed parts being unserviceable, it seems to me that the carby must be at fault somewhere. As you say, take it off and disassemble, blow out all orifices wih compressed air and try to divine how that particular carby works, so you can identify any blockages. If fuel was leaking out of the inlet manifold tube when you turned the motor over, were the plugs wet as well ? In other words, was fuel getting to the combustion chamber ?

Chappers Posted August 12, 2007 Share Posted August 12, 2007 It sounds like you have a problem with your carb which is your fuel to engine problem check float levels and as mentioned clean completely,also check the float valve for sticking either way open or shut.You can always fire your engine up if you remove the air filter and pour a little fuel into the carb if it's a fuel starvation problem. If you do pour some fuel down the carb Keep clear of carb when firing incase of a blow back,you wouldn't want a face full of burning fuel :shake: Secondly you said your compression tests were o.k so you possibly have worn inlet valve guides,which would account for a large amount of smoke when you rev the engine.The suction on the inlet can sucks oil up the sides of the valves stems and into the cylinders. It's not too bad to check/change them when you've got the head off. hope you get it sorted Regards Steve Quote Link to comment Share on other sites More sharing options...
Tony B Posted August 12, 2007 Share Posted August 12, 2007 WC can have a Zenith carb or a Ball & Ball. Be sure you know which type you have. military media do the manual on disc, well worth getting as it also has a lot of other info. the accelerator pump on B&B can cause problems.
