I will check with NAPA. We have the older people in our town working at the Autozone. When I go in, the lady says "Is that a 74 Maverick? That was my first car! and in the same ugly yellow color!" The NAPA has a better selection of parts, but their hours suck! And closed on Sunday, when I do most of my work. I will wash the breather out with gas tomorrow (87 octane, or 92? ) Let's see if this solves some of my problem...
The K&N seemed to take on the engine oil from the vapor(soak up) and create more surface area and it it would them get blown all over the valve covers. For my application they seemed to make my problem worse?? The PCV valve on my car was drawing a little oil up into the carb when my problem was at its worst(thats when I had no built in baffles) so I just ran without it and never went back now that I don't have to do emmissions. PCV -- Positive Crankcase Ventilation Was a polution control device intoduced in the early sixties?? It is basically one way valve that allows the engine to draw any blow-by within the crankcase, lifter gallery, valve covers(anywhere that there is open airspace in the engine) that can contain blow-by which is defined as polution that would have vented to the outside of the engine to the atmosphere. The valve opens when there is enough vacuum to pull it open and snaps shut when there is lower vacuum. I see is as a two sided arguement. The PCV valve reduces polution as the blow-by is fed back to the engine to be reburned and will also aid in your rings sealing (I mentioned the racers alternative to this above). The better ring sealing is a benefit but the more pure air -- really oxygen you can shove into a cylinder with the right amout of fuel the more power. This is how nitrous works. Imagine oxgyen is a container of water your pouring into a cup and what the PCV adds is dirt. The less dirt/contaminated air the more pure water/oxgyen will fit into the cup. More oxygen equals more power. I have always noticed colder more oxgyen enriched air equals more power and even though it might be barely noticable I would rather have the benefit to feed the engine the most oxygen I can when I am out for performance.
my on another problem i see your fuel filter them glass ones like that are a fire Haz there junk!! they leak and crack very easy i woud pull it and put it in the trash..and get one of the $2 plastic ones
"slightly bigger cam" could be there is less vacuum to the pcv so its not doing it s job ..check the vacuum and see what its at ..at idle ..hows the trans shift ??if its auto
Trans shifts kinda wierd. Typically, will hold 1st OK, then hit 2nd and quickly move on to 3rd. I usually use my B&M floor shifter, if I want the gears to do what they are supposed to. If I am just cruising around town, I will put it in "D" and let it shift where it wants to. So, Do I need to check the vacuum at the valve, and buy a valve that is made for that vacuum?
New 3.80 gears is a huge clue. You have that puppy revving, even when you are just cruising the freeway.
Don't do too much "cruising the freeway", and when I do, I am the slowest guy on the road. Keep it around 60mph, but I get there QUICKLY Is there a PCV valve fix for this issue, or is it just a worn or wearing motor? Also, do I even need a PCV valve, or can I skip it, or bypass that entire line to the carb?
You need a PCV valve. From what I have read it removes harmfull gasses from the engine that would otherwise corrode interal parts over time.
With the (slightly) larger cam, and all, do I need a PCV valve that works at lower, or higher pressures. I don't know crap about PVC, or PVC. Actually, I know quite a bit about PVC, but PCV stumps me?
The PCV valve (Positive Crankcase Ventilation is just a modulator to control the amount of air running through your crankcase to vent the engine. Just buy the factory correct one. Do a Google search for the function of this system. I have typed the detailed explanation way too often and I am all typed out.
Older engines did not have PCV, just vented oil vapor into the air. When the government got into it, had to keep the oil in the engine, sealed the system more or less, pressure built up more, PCV came into play. Check some of the late fifties cars and trucks. Something like a 3/4 or 5/8 hose just blowing the oil vapor under the body... kept them from rusting out tho...
