Massive oil leaks.

Lonewolf3165 said
90% of the new motors I see pissing oil out of every seal/ gasket or the stick are either only runnung 1 breather or none. All of them resolved the problem(if caught soon enough) by installing some sort of Positive Crankcase Ventalation system on it. Either a conventional PCV valve setup or moroso Vac-U-Pan kit or a vacuum pump, but something has to create negative pressure in the crankcase for everything to seal properly. 2 breathers won't create negative pressure & will likely still leak.

I have a beer that that guy will not show up for a run against Mad Dart even if he internets that he will, like he already did.

This guy is lucky he didn't bow up the valley cover. Must be a cast Indy one. This guy was not so lucky:

I was gonna use 2 breathers like my 416 has (and it works just fine that way - they dumped down BY the headers and didn't make oil) on the 540 but after some deliberation, and getting a new vac pump on the KOS 499 that solved the issues I was having with the 16 yr kludge that was on it, I just transferred the vac system to the 540. That is except for the pop off valve or whatever that $150 thing is called. It is screwed into a spot welded onto the valley plate on the 499 and we didn't provision the 540 for vac when it was built.

I wonder if too much vac is bad also? I am contemplating the real cost of not putting a relief valve on. Maybe weld a AN-12 thread nut to the valve cover and thread one of these on which will give a 90 degree angle to slicken up the vac connection on the valve cover.

Why the neg about Moparts? Some very good tech in the unlawful racing forum, especially for fast BBs. Lotsa old school racers and current builders that have been around a long time and will share what they know. They even have a thread on my KOS Demon that was there before I bought the car.
