Blocked off valve cover

what would happen if i disconnected the two hoses on the valve cover and had it completely isolated??? i think i just asked what would happen if i eliminated the EGR valve and the return.

Re: Blocked off valve cover

I would think that too much pressure would build up, and you would blow out the gaskets.

Re: Blocked off valve cover

You do mean PCV, not EGR right. If so, you would start leaking in places you didn't know could leak!

Re: Blocked off valve cover

Yeah, PCV is a good thing, and your engine is designed to run well with it. It keeps things clean inside and the engine will run better when it is connected.

Re: Blocked off valve cover

My engine doesn't use a PCV system.

I think I'm only days away from replacing my valve springs...I hope, and while the covers are off the motor, I plan on adding a 1 1/4" X-over tube between the valve covers, with a K&N breather filter at the high point.(maybe 2 )... Big chevys need alot Breathing room, I think this should keep things cleaner under the hood, when I start thrashing it. : )

Re: Blocked off valve cover

WOW..actually that was just a curiosity question i was not thinking of doing anything. i don't have any blow by or leakage anywhere. i was just wondering in reference to cleaning up the look under the hood if i went to an open air filter in the warm months.
man you guys scared me so bad i think i might drill some extra holes in my valve cover (lol)
thanks for the info
its amazing what you can learn when you are curious! most of it does not even cause pain!

Re: Blocked off valve cover

Can you imagine the amount of air and oil mist moveing around under the pistons at 5000 rpm ?

Re: Blocked off valve cover

If you want to run an open air cleaner in the summer, you can replace the pcv intake hose with a small breather on the valve cover or a breather filler cap. Most larger auto parts stores sell them. I run an open air cleaner with a chrome breather cap. I only have two vacuum hoses, one for PCV and one for vacuum advance. Really clean. 'Course, 1964 engine technology didn't have egr or air pumps or cats. The only reason that most racers don't use PCV is that they don't generally run enough vacuum to suck out all the excess vapors, so they run big breather elements. They also rebuild often enough and change the oil after every race so that the crud doesn't really shorten engine life much. In a street/offroad use engine, the PCV system sucks the vapors out of the engine and helps keep the oil free of dirt and especially moisture. Thats why engines with really bad blowby create 'mayo' in the oil. I had a Ford 2.8L ranger engine that had 220,000 miles on it and had so much blowby when it was cold that the PCV system actually blew instead of sucked.
