ditchman Posted March 10, 2017 Author Report Share Posted March 10, 2017 Cheers I'll have a look at some point when I need it again if you think about it ..."why does it only run proper on choke"...........................putting it on choke creates more of a vacumn ....so what it is doing is sucking harder to get fuel.... why... blocked filter blocked jet in the carb simple fix ....

ditchman Posted March 10, 2017 Author Report Share Posted March 10, 2017 Ditchman - your unfinished welding blob looks like my welding (finished product). nickle alloy rods can be difficult to use...ok in straight runs but small jobs like this need to be "blobbed"...........as long as your welds are free from holes ...curl....polarity issues ...they are usually fine..........it can be difficult with this kind of job ...as you dont want to get the arc tooo close to the threads...sort of ...lay off and let it flow there ...sort of.... ...also i had to ...weld...peen...de-slag...grind.preheat..weld peen...de-slag....you get the idea....just a lot of different things to do in such a small space and timeframe..........

Gordon R Posted March 11, 2017 Report Share Posted March 11, 2017 I have worked on many Ford Pinto engines, but set the valve timing 180 degrees out when refitting a cam belt. I couldn't get it to start - penny only dropped when a mate called and mentioned valve timing. Quote Link to comment Share on other sites More sharing options...
subsonicnat Posted March 11, 2017 Report Share Posted March 11, 2017 Yep, Can be timed 180 out,as most engines really,first thing my Dad taught me.. TDC No 1.. Quote Link to comment Share on other sites More sharing options...

ditchman Posted March 12, 2017 Author Report Share Posted March 12, 2017 "in da shed " again............"mainly doin' " first pic is showing how the turbine sits in the cassett housing......i have putthe 2 bearing/carriers on to give an idea as to what happens oil comes in from the top at 30-35lbs/sq" the top half of the cassett is pressurised to oil pressure the bearing/carrier thro the little holes is "pressurised" and the turbine shaft is floated on a thin film of oil to the left of the left carrier there is a chamber to the right of the right carrier there is a chamber the oil then floods into the left and right chamber the chamber is at zero pressure as it drains into the sump via the big drainhole on the bottom of the cassett there is a few other bits i have missed out ...spacers etc.....left them out so as not to complicate the issue Quote Link to comment Share on other sites More sharing options...
ditchman Posted March 12, 2017 Author Report Share Posted March 12, 2017 on the second pic you can see the oil gas seal....it is most similar to a piston ring................ failed turbo's fail for several reasons leaving oil changes to long wrong oil driving too hard on start up closing down engine whilst turbo is still very hot waste gate clogged shut poor quality fuel no or knackered air filter turbo's should not break....they are fed copious ammounts of oil to cool and lube' them......they should be driven HARD but not stupid.. so if you vehicle has a turbo....think what it has to go thro'......USE IT BUT DONT ABUSE IT.......

Del T Posted March 12, 2017 Report Share Posted March 12, 2017 Wasn't good! Just put it on too after changing from a smaller one. Bled it all up ,checked and double checked all pipes and clips, first time it came on full boost (1.6 bar) pop!. We think it may have over sped and caught the side of the housing.
