    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.
  • Check your warranty book before you go through with this job.

    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.
  • garypengarypen Posts: 1,483
    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.
  • 00impala00impala Posts: 474
    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?
  • b4zb4z Posts: 3,372
    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: 1,483
    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 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

    For the Filler Cap on the Radiator...Here is what it says in Popular Mechanics 9/01

    Got a plastic-tanked aluminum radiator on your 1999-2000 GM car or light truck? If you do, and the engine runs hot, overheats or looses coolant regularly, the problem may not be the plastic end tank, but an imperfection in the sealing surface of the plastic filler neck where it seals to the gasket on the filler cap. To cure this, lightly sand the filler neck sealing surface wth 400-grit sandpaper and a block of wood to true it up, then replace the filler cap. TSB 00-06-02-001

    I remeber someone having to replace the cap to solve a problem, maybe this was the cuprit? Don
  • Ok, fuel filter and PCV change out... I took photos for a oil change article, but I don't know where I filed that one.

    Did an update last night, including the rust issue. If your warranty is gonna be up soon, you might want to check it out. I'm still considering different fixes and am open to suggestions.

    My wife and I were having lunch at Applebees this afternoon, right down the street from the Chevrolet Dealer that fixed my Cradle and ISS, When we were leaving I mentioned stopping by the Dealer to mention the Seeping Valve Cover Gasket, we pulled inside and the Service Director walked over and said hello to me by name, and asked what was up (we did not buy the car there) and I popped the hood and mentioned the oil I saw, he got a flashlght and we took a look, he said to them what he is looking at is "seepage" and if he saw a shiny pool of oil he would say it is leaking, he said that he could not guarantee that in 10K miles the same thing would happen due to vapors and heat and all other degrading forces on the gaskets, but would be ""more than happy"" to ""replace the gasket"" for me under Warranty at my convienence, I made an appt. for 2 weeks from now, I also mentioned the ISS on my Wifes '01 and how we had the selling dealer do the Lube and have been happy ever since, and how my LS with the new Cradle and ISS (from this Dealer) has been holding up fine, He talked about how they were replacing the ISS's as in my LS's case then changed to Lubing them. he told me how the lube all went to one end and that caused the Dry Spline Clunking, he went thru the process of the lube, they take the ISS off the car, put it in a Vise and shoot the Lube into it, he then said (AND I FOUND THIS OF PARTICULAR INTEREST) that they install a "PLUG" to stop the Grease from going all the way from one end to the other and leaving the other end dry, he said this would not need follow up lubes due to the "plug" they put in there during it's time on the bench, so I am unsure if follow up visits will be needed on our '01 or not, he said it should be fine, anyway, I am writing another Positive Letter to this dealership owner as this Service Director is the Nicest guy I have yet encountered,He Explains things and most of all he Listens then lends advice (as he said about the gasket, to them it is seeping (no biggie), but he understands to a customer it is something serious although it can be corrected easily) He checked the Manifold gasket and the Front Valve Cover gasket and they were Fine/Dry... By the Way.... He is the one who ordered the #103 Booster (@ replaced the Cradle and ISS)for me without listening to the Stereo after the Selling Dealer wanted to send my radio off for repairs thinking it was soildered wrong at the factory..Glad I stopped by today! Don
  • Glad you have been having so much fun maintaining the LS! :) I have to get out there this weekend since we will have balmy 50 degree weather. I think I'll try to find the PCV valve and give it a shake or two, as I am not sure if that was part of the 15K maintenance package.

    Also good to hear about the great treatment you received from that Service Director! Sure makes owning an car that much more enjoyable knowing that if any issues surface with the vehicle, they are addresses in a prompt and couteous manner and on the CUSTOMER'S terms.

    My local Chevy dealer is rather pleasant to deal with as well. I think I will drive up there and drop off that CUSTOMER SURVEY card in person. I will get a free lube service out of that. GM must be sticking it to the dealers these days about customer satisfaction judging the way the service department was pressing the importance of a pristine survey result.

    Should work to our (customers) advantage.

    Take care, and keep enjoying those Impalas.

    I am glad I could help you find it ! thanks ----------------mattmcdill
  • That is minor surface rust but it is annoying. Coat that area with POR-15. Twenty years from now that coating will still be there.

    This has to be the most popular Edmunds Townhall topic of all time. Am I right Shifty?
  • Well it is good to still see all the familiar names, I last checked in around 12/00 as boden213, alot has happened since then moved and a bunch of other stuff, boy did I miss this site. Let me update you all on the 2k impala. Just hit 50k!!! Drove across country @ 31 m.p.g., only problems... blower fan replaced, a.c. condensation on the passengers side, and now the steering wheel kind of pops when turning. No clue on that last one.
    Hope all is well and I will check in daily from now on.
  • It's only the most popular group because half the messages have nothing to do with the Impala.
