Oil cap drill & tap

[sixpack]

Back to installing my catch can,thanks for iding the inlet and outlet a okay on that Would it be a benefit to drill the oil cap and include it in the vacuum circuit?

With as many catch can installs to be found on this forum, if no body else has done it by now,.........do not do it.

sure. That is a common source for clean air feed to the crankcase. Look at the 1LE clean side separator or the ones from RX and Elite. All the same thing.

When you're nailing it, at max crankcase pressure, you might get some oil going out that hole into the air intake. That's why a clean side can/separator is a good idea there.

Depending on the configuration. You wouldn't want the breather to be on the same line as the PCV setup. You want the breather to get clean air, not crankcase ventilation.

You do NOT want to mix the clean and dirty sides together. The cleanside provides filtered, MAF metered fresh air to one bank making up for and flushing the foul or dirty vapors out the opposite bank.


With the Elite E2 or E2-X, you replace the oil fill cap with the CSS (cleanside separator) and that then runs to where the OEM cleanside line ran before (the CSS traps and prevents oil from back-flowing into the intake air bridge upstream of the TB).


The dirty side is where the damaging compound laden vapors are evacuated (removed) from the crankcase and the Elite systems separate and trap the oil and other contaminants from the PCV vapors.


Using the dual valve cans you also improve on the OEM PCV systems function by providing a secondary evacuation suction source to take over when accelerating or at WOT when intake manifold vacuum drops to zero providing constant evacuation and never allowing crankcase pressure to build.


Hope this was helpful!

Thanks all,armed with all this feedback how can I go wrong.
