You don't have a timing chain cover canister, so I would run a hose from the fuel pump boss to a "Y" and then to the carbs. That type of PCV system works best out of all that BL used to reduce crankcase pressures and leaks. Easy enough to try and you can always remove it if it doesn't work. Moss sells the Y piece.</div><div dir="ltr"><br></div><div dir="ltr">At Gingerman Raceway last month one of the guys had to replace a broken rocker shaft on his Bugeye engine. He just removed the pedastals, replaced the broken shaft, and then retorqued the pedastal bolts.

</div>
<div>Is this a new development or has this engine always had this problem?<br>
<div><br>
</div>
<div>Are you having any leakage from the rear scroll "seal"? (Or do you have a proper seal back there)?</div>
<div><br>
</div>
<div>
<div>It sounds like you need a little vacuum on the engine.</div>
</div>
<div><br>
</div>
<div>Can you set up a vacuum line from the valve cover to the intake manifold that would replace the line that is usually from the timing cover to the intake manifold? It shouldn't take too much vacuum to relieve the pressure in the engine. Especially if you
have an otherwise healthy engine.</div>
