Read the directions on the first page of this thread. You need to cut that metal rod. Just cut mine with no issuesLittle help and advice please. I bought this intake manifold on Ebay two years ago when the only thing I knew about FJ40's was it was going to cost me a lot of money to get my registered. So I sent the manifold and new MAF 6-1 header to Seattle for ceramic coating. Now I am preparing to use (presuming I buy the engine in Quito next week) these items. I set the new carb on the intake manifold and see that I have clearance issues with the tube that is installed in the carb spacer. Cannot face "up" at the rear as it hits the linkage. Cannot face down at the rear as it hits the linkage to the idle adjusting screw. At the front it cannot be installed up as it hits a long rod that passes through the carburetor. My old 1 bbl doesn't have anything like that shaft. Does anyone know what it goes to? I am "assuming" that the tube on the carb spacer is where the PCV hose will attach. I have Dorman rubber caps on the two intake manifold fittings, the larger of which I will presume is used for a power brake booster. Thanks.
