As you might know, the lift is our bottleneck. Here a long awaited motor job has finally made it to the lift. On a trip south last year, this coach spun a bearing. Didmt do much for their vacation, they wanted a fresh drive train so a Monster transmission and our roller cam 455 will put this puppy back on the yellow brick road.
This machine WAS holding down the lift getting its new single fuel tankAlong with the single fuel tank in it we’re also installing the FiTech fuel injection system. First thing is to pull up the intake manifold for a cleaning and a fiber gasket set with stainless steel exhaust crossover block off plates must be added to keep the heat away from the fi throttle body.CHeck out the 1/2 box of “Keeblers”, that’s the carbon build up on the tin intake gasket, the underside in this valley had the other 1/2 box which had to be vacuumed out
First the “Turkey tray” tin intake gasket comes outI took the nasty lump of metal to Mikes machine shop for a thorough chemical wash like this 455 block is gettingand here’s the carbon covered, never been removed greasy intake Mike needs to do his magic onDI’d it need block off plates…..you tell me!This is the dreaded secondary hairline crack that’s caused by our concave intake manifold design. If you change to fuel injection you must install stainless steel block off plates and glue in a fiber gasket to effectively take away the heat. If this is something you would like to do, give us a call….We’ll help u thru it..This is another intake out of the cooker, check out the underside crack someone had tried to fix….the “bubblegum braze they tried fell off in the cleaning….this intake is no goodThe only accepible crack is the one in the secondary port middle wall, any cracks on the underside like this and it’s a different intake for you! With these original intakes cleans with their exhaust crossovers blocked this part can once again be reliable. Stay tuned for its install and FiTech fuel injection install on top of it…….
Ok, bout time for the day to turn on, its nice having someone greeting me at the door coming in….even if it IS FOR foodIts nice anyway
See ya tomorrow……..
THAT is the dreaded crack from the badly designed concave I take manifold all of our coaches have. To ahead, stick your head in the sand…..if your isn’t cracked it will. If you’ve seen no problems with vacuum sooner or later you will……and you KNOW when it will happen! Fix this BEFORE it fails which it will! All the new fi systems will all but require this to keep from cooking their systems so stop worrying about polishing your coach until you have blocked off the exhaust crossover ports in your intake. If you wanna do this, give us a call…. We’ll help ya thru it.
