    As long as it works Jim.  If you get the chance of a spare manifold, grab it and keep it one the shelf.

    Got one in stock, and another to be skimmed, got 3 GMC engines for rebuild in the future as well...Soon to start on the ROYAL DUKW...

    Fire it up, wait till it starts acting up, then shoot some WD40 at the inlet manifold to head connection for 1 and 2.  

    I'm thinking it might be moving when it heats up and starts drawing air.

    Jim,

    Just seen your previous post about skimming manifold and fitting new rings. If you skimmed both manifolds together then the rings may be a bit too wide now and not allowing the manifold to compress the gasket. I normally measure the rebate in the head and manifold, the width of ring and thickness of gasket to ensure the assembly will fit correctly with no pressure on the rings.

    Good morning Richard,

    Bad news on Engine, started and ran well for an hour, everything normal, temperature stayed 140..Then started running erratically, overheating and serious vibrations...back to square one again..fun fun fun..Thankfully we have no clients visiting at the moment so no tours(although no clients no money coming in) so time to solve the problems..After this got the 1937 SAURER, Bedford QL, and Humber...2 big projects rebuild of QUAD and MATIDOR...Thanks for your help will keep in touch, keep safe in these bizarre times..

    Take out no's 1 and 2 plugs and swap them with 5 and 6, see if the problem moves. Strange that before the repairs, cylinders 1 and 2 were giving trouble. As has already been mentioned, it could be drawinng air on the intake manifold joint which opens up when the engine gets hot. These exhaust manifolds are prone to warping and if machined then the intake manifold has to be carefully matched to it so all the faces are in line.

    Thanks Richard, It's the first time thats happened to me, shall check it over Monday..

    Will try that on Monday, when i"m next at work, Had the manifold skimmed, new central locating rings and gaskets fitted...Shall give you the news next week...thanks

    Curious ...do you have fresh fuel .....? I seem to regularly run into issues with poor fuel..I often start engines for the first time with high octane fuel...? 

    Jenkinov

     

    The fuel is fresh and new, with additive and filtered, besides that would effect all cylinders not just 1+2...But thanks anyway

    my question would be why in the first place did you need to replace the valve gear on just . only on those two cylinders ?

    The pushrods on 1+2 cylinders were damaged, be that being due to sticking cam followers or valves or weak return springs????  so to be safe all was changed..

    Assuming you are certain the problem lies with nos 1 & 2 cylinders, and bearing in mind that you have replaced most of the valve train for these two, have you checked that the valves and rockers are receiving oil - if not, the valves could stick as the engine warms up, and the problem will disappear once it has cooled again. Presume that you also replaced the spark plugs? Try replacing them again, even new ones can sometimes be faulty.

    All ignition system is new, problem lies with 1+2 as when HT leads are disconnected the engine tone stays the same, disconnect the other 3<6cyl  engine tone drops..Im running engine without rocker cover and side covers, getting oil to all..Will be back on it again on Monday...Will let you know the outcome..


  9. First post for a while, got a GMC running Like a bag of nails, new headgasket fitted, four new push-rods, valves and springs on no 1+2 cylinders, carb + fuel pump overhauled, LT and HT system changed With new coil..enging timing set up and strobed, fins well fire 10-15 mins then starts to miss on 1+2 again, got 9.5 bar compression through all 6 cylinders, good sparks, checked, rechecked, valve clearances, CBs, etc, all good...


  10. Thats not my welding, its the previous mechanics, who has butchered most of our fleet of ww2 vehicles, he removed the original oil filters and fitted modern filters and used air compressor pipes for oil to pass, also changed the fuel systems to accomodate a modern car primer pump, The problem i've got is to repurchase the complete systems as he threw everything out..

    The vehicles are WC52 and command car,  Kubelwagon, Willy's Jeep, Bedford QL, Humber and Morris Quad

    Luckily he wasnt allowed to touch our GMC's and SAURER..

    Thanks for your help..

    You could try Chris Morter, he does have spares from vehicles which he and dad John have broken. I couldn't get the linkage when I put the correct carb on my QL, had to make one. Bear in mind the QL is very,  very slow on hills even with the correct set-up - doesn't seem to matter whether they're loaded or not!

    Mike.

    Have you got Chris Morters email or phone number, As I'm in Normandy France not UK..The problem with our QL it cuts out on steep inclines due to the Zenith carb being half the size of the Solex...Thanks for the help...


  12. my first time on the forum and hoping some off you nice people will help. I work at Dday Acadamey ROTS..I'm after the following pieces

    Humber rear and front brake cylinder kits, Hub seals the same; Front P/Shaft nuts and bolts

    Bedford QL Solex RZ FAIPO Carb Kit X2,  Complete accelerator linkages on side of carb.. The bedford currently runs on a Zenith from a 1500 wt bedford

    The previous mechanic ripped out the system, cut, welded and threw away what was left, the bedford runs well, until a steep incline...So I
