    Trasher supercharged MC. A lot of parts need to be beefed up. Not only engine and transmission, but also CV joints / half shafts, radiator, fuel pump, fuel lines, wiring harness, and different "brackets and assemblies".

    I looked all over the top of the engine with a neon shop light and cannot find it, all I see ging into the engine are the Fuel Injectors. Also, I spotted the Power Steering canister, wow it that thing in an out of the way spot...Can you be more specific on the PCV location? Maybe this is a tip/Trick for the How To Page on Nathan's Site??? Thanks in Advance Don
  • Took my baby to the shop to get an exhaust system done. They're gonna get rid of the U-bend, and the resonator. The guy told me he was gonna run a 2 1/2" pipe from the CAT and have a Y right by the spare tire dip, then it goes to 2 dynomax mufflers and tips. $530 for the whole setup. I just hope they wont screw anything up and this is for the best of the car.

    Since the invention of the PCV Valve (POSITIVE CRANKCASE VENTILATION) back in the fifties, they have always connected right into the top of one of the engine valve covers via a rubber grommet. A small hose will come off the PCV valve to route the crankcase gasses collected in the upper valve chamber back into the induction system to be burned with the incoming fuel/air mixture. To check whether the PCV valve is functioning, just remove it from the grommet and shake it. There is a small metal ball inside that should rattle around and move freely. As long you can hear it moving there is no need to replace the valve. They don't wear out; they generally just gum up after a few years.
  • ISS was replaced on Monday at 28,000 miles. Steering is much better now, firm and feels like new. Hope it lasts.....

    I dug out my '00 shop manuals, and they make absolutely ZERO reference to a PCV valve in the 3.8 Engine section. They do use one mounted on the left valve cover of the 3.4 engine, however.

    I thought ALL engines used PCVs ever since the beginning of emission control, but I guess I was mistaken...

    I don't know when they were introduced, but American cars didn't start getting them until 1968. It was a government mandate, so unless modern technology has found something better to replace the PCV valve, all cars today have them. Traditionally, they're on the valve cover, and just pop in, but some newer designs instead screw into the air intake. I had to hunt around to find the one on my Intrepid, which screws in sideways, into the plastic air intake at the top of the engine. The 3.8 Impala may be similar.

    Our 1964 Plymouth Belvedere had a PCV valve. So it was earlier than 1968.

    My XJS doesn't have one either. Apparently it's possible to recirculate those vapors without one.

    I get to save $1.98 each year ($3.96 for both cars). So, I got that going for me, which is nice.

    Looks good. I like the triple taillight clusters. It brings back the original look. Of course, they'd have to all work to complete the effect, unlike the bogus inner ones we have now.

    and maybe the little booklet at the auto parts store was refering to the 3.4? I don't know? It just said 2000+ IMPALA, I'm just asking if anyone can confirm or deny that the 3.8 has one, since I have spent way too much time looking for it without finding it. Once it is located, Gomer Pyle or Goober Pyle would be a pro at replacing it, it is that simple. Thanks Don

    ...was that Belvedere a California model, or did it maybe have a replacement engine from a newer car? I have a '67 Catalina that doesn't have a PCV valve, and I was pretty sure it was '68 when they became mandatory. Maybe they came out earlier, but just weren't made mandatory until '68?

    I had a 3.8 with a PCV valve, but it was also an '82 Cutlass Supreme! They've changed a lot on that engine in 20 years, so it's possible the PCV valve is one of those things!
  • Picking up my K&N filter this afternoon, and will also check the price/availability of a fuel filter. Anybody know @ what the fuel filters cost, and if there's any brand to avoid/prefer?

    My grandmother was the original owner and it is a S.C. car.
    I've got some pictures of the engines somewhere and i will look for them to see if I remember correctly.
    When I was 18 i took the valve cover off (slant 6) and put a new gasket on it, so I am pretty sure there was one.
    We sold the car to a friend in 1984 for $150 who said he was going to use if for his paper route. He promptly turned around and sold it for $450.
    Beautiful car with great lines, unfortunately it leaked water on the driver's foot from day one. It did have the pushbutton auto transmission which was a lot of fun.

    Wal Mart and it is FRAM and it was $9.97, I'm sure there are others, the original one I replaced was a AC/Delco part. Can't say as to the better one? if one is better than the other? I plan to change it regularly so FRAM will do for me. Don
  • garypengarypen Posts: 1,482
    Fram, Purolator, AC/Delco. They're all fine.

    For those who are mechanically inclined, curious, or just plain want something different - modifying a stock vehicle is the way to go. Plus there is the pride in accomplishing and having something that is unique. Not everybody has the same tastes or wants to accomplish the same
    goal the same way.
    A guy at work asked me why I wanted to stuff a small block or a supercharged 3.8 in my Impala? Why would I want all that power? I told him because I could.

    The PCV valve is on the passenger side of the upper intake manifold , on the very end , You will see a a few wires going to it , under this is the PCV valve , just take it and turn the whole thing counter clock wise , just like taking off a radiator cap , it is spring loaded and has a O ring around the assembly . thanks-----mattmcdill
  • 00impala00impala Posts: 474
    When you take the plastic engine cover off you will see a "Pressure Sensor" on the left end of the upper manifold, I diconnected the plug from it, twisted it counterclockwise from the bottom of the whole thing as Matt said and Voila' there it is sitting down inside the Cap/Sensor I just removed, I took some needle nose pliers to pull it out,I also removed the Orange O Ring and wiped it off and put it back, the FRAM PCV Valve does not come with a smaller Black O ring that was around the AC/DELCO PVC Valve I found when I pulled it out...so I put it on the FRAM before installing it, I have a friend who distributes AC/DELCO parts to Dealerships and I may get him to pick me up some original AC/DELCO parts for the next time. Thanks Again MATT, I knew it had to have one, it was just hidden from plain view. It was moving OK when I shook it a bit, but I could tell it was full of OIL and the new one is really agile.

    Nathan, Are you taking Notes? Would be a great tidbit to add to your "How To" page.....

    Also... While I had my flourescent light looking over the engine, I noticed in the area of the rear valve cover in the middle of the valve-cover where it meets the engine some oil, not alot, but it looks wet with Oil.... like the gasket might be comprimised, not leaking,maybe seeping.. but I will have them check it during my next oil change/ trip to the dealer..I was originally looking for Anti Freeze like some others have mentioned finding in other places and Battery Fluid.....instead...I struck some seeping Oil :( anyway... Thank Again...... Don
