it drives me crazy, as it is really had to operate. i got one leak less, but it still leaks somewhere. have to go to fix the second one. than im ready for the next ones. maybe its just like p.laitinen told me, that the hoses might be toasted, of the E85. that would be awful. but as always, Pekka might be right on this. :-(
i would like to get the engine running again. summer is pretty short in here.
as i have been hunting for the leaking places from the turbo-engine, it has been a really knuckle busting job, but one of the intake manifold is coming apart, (i guess that i will get it back one day) and trying to figure out how to glue it together, with something that really holds up. any suggestions?
Today was a day to take a bath, with a pressurized throttle valve, and it went pretty well, the more you give air/pressure, the better the jacuzzi feels like. :-) BUT have to think what can be done with this. i don't know any machinists... i would like a 65 mm throttle bore , but one that doesn't leak. ok whats next?
if the weather will be decent, i will go to the cottage to freeze my butt, and try to pressurize the rest of the intake. and the best result will come, if i loosen the rocker shafts. i wonder how this will turn out. + it would be wise to check out the hoses too... and the pressure is under 0,3 bar in this clip
Ok so far what i know, is that the tube with the bow leaks a tiny bit of air, as i changed it to a straight pipe without welds or any BOW. now the tubes from the turbo to the end of intercooler is ok for me. BUT, today i tested the part from intercooler to the T-inatkemanifold, AND couldn't get any pressure to that. so the leak must be massive. i took it out of the ghia, as i want to get a better view what can be done, or is it useless... looks like the culprit is the china-throttle body. as it was before too. but i have to test it before I'm sure. IF the manifold setup is good from the T-shaped manifold, this thing could be running better one day. It was around -5 degree Celsius today, so my fingers were frozen in this hobby. i should get it to a warm garage, but there's ice and snow so picking up the ghia is not possible right now.
Ok, first part of the leak down test partially done. Even the bigger compressor was out of order, the small tyre compressor made some pressure for the system, and there's two spots that needs to be fixed, then i need more/bigger pressure, to see if there's more. but looks like the parts in this green line is ok. well atleast semi ok. the weather went to sunshine to pretty cold, so this test-thing will continue later on, :-)
i´m a bit nervous, what will be found later. but first this tested part has to be leak proof.
Today was a great day, even i didn't get to the great final. i had to test the "Turbo Boost Leak tester" set... to pressurize the compressor side...BUT i couldn't get any pressure to the cold side of the turbo. none. i thought that the new leak tester is broken. but no. so now i have to test the system in smaller parts, like plug the intercooler, and test the tubes before that. or maybe just plug the tube where the BOW is located...
have to go back tomorrow, if there's no wind and a bit warmer, as it was cold today. and i have to locate different size plugs for this... but maybe there's a reason that this black ghia doesn't have many horses...
