oh yes MAF not MAP not real good with these names on new stuff yet

just finished my PCV line reroute on my 1988 GMC pickup 1500 350 2 wheel drive
--- this was opposite of 1997 chev pickup -- PCV valve on passengers side (left side) with vacuum line on lower part of throttle body after butterfly and just a vacuum line from ride side valve cover to a spacer between air filter and throttle body. So capped vacuum intake at bottom of throttle body. Applied new vacuum line from PCV valve to a new Tee at the spacer behind throttle body and new vacuum line from Tee to right side valve cover (old line was broke at valve cover)

One question there is a vacuum line real close to old PCV vacuum line inlet to throttle body like 1/2 inch from PCV inlet. This line goes to a canister to the right of radiator, can this vacuum line be rerouted also to inbound air flow to throttle body ?? I think it can but want a better opinion .

---- as for 1997 chev truck driving has not changed much except for realizing a lower idle

Been looking for non-resistor spark plugs -- did not know exactly what they were until I found this utude -- now I know what I am looking for I think going to try again to buy some non-resistor plugs but it not find them I can make them easily

TracyG as for Rocket Oven metal 55 gallon drums will work great for oven part -- to help retain and control the heat -- can line a section for oven with fire brick using fire clay with mortar mix using an adjustable air flapper to control temperature -- this oven can be in the flu exit for smoking meat or can be part of fire box without the flame touching meat -- just a thought

now there are 3 rows like the picture about 5 x 6 x 80 feet each sell to many BBQ places

Hi Gerald, sounds like ya got the PCV re-route done right. That other line is from the charcoal canister. The charcoal canister traps fuel vapors from fuel tank and releases (purges) them while engine is running. I don't see why you cant re-route that purge line from TB to air inlet also. If vacuum is present in the line during idle (check at the canister end), then re-routing will stop another "vacuum leak" and improve manifold vacuum stregnth. If there is a vacuum-controlled purge valve on the canister, it will be controlled by a small dia. line going to a manifold vac. source, and this smaller line needs to stay connected factory stock.

Quite a stack of wood ya got there, I wouldn't mind some of that for my brand new Rocket Oven. I test fired it 3 times to check it out, then baked a perfect loaf of bread in it 2 nights ago. I'm "chuffed" w/ it (as Rino would say!) This thing is virtually unknown of, there is exactly ONE chap in England (I think) who has 3 vid's on youtube of his version, I shamelessly copied him. I have searched the Net, his is the only thing like it I can find.

Rocket Stoves are becoming popular though still un-known by the masses. 100's of vid's on Youtube. Many ways to make 'em and some commercial versions avail. Rocket OVEN though, nope ya gotta make your own, there's a few rocket Pizza ovens where flame/flue gasses contact or nearly so the food, plus Barrel meat smokers/BBQ's etc. But a wood fired oven w/ isolated oven chamber, that's about unheard of. Here's mine:











I've had it up to 550 deg. F! just to burn off residues, etc. It's a prototype, and needs a dedicated firebox still, right now it runs on a rocket stove thats got another rocket under it for a spacer, so looks odd. If I had some of your wood Gerald I would split it into kindling, that's all that's needed for fuel. Rocket Stoves are very fuel efficient, been running the Oven on sticks and twigs, 1" wide sticks are on the big side for this.

I know this has nothing to do w/ the Groove, though it is loosely related to fuel Efficiency!

TracyG oh very nice Rocket oven you do not need any welding -- could swap out the rocks for some lava rocks may hold heat better oh better not show my wife she loves to cook bread

on 1988 1500 350 GMC pickup reroute of charcoal canister to same line as PCV done finish about dark have not ran it yet

still looking for non-resistor plugs -- 3 parts houses now have no idea -- going to NAPA next if they do not have them will be calling online to order
-- I do allot of different things over the years and it seems to be getting harder to get parts for many things , could just be me but its like no inventory is hurting businesses allot

Thank you Gerald, the rocket Oven makes me feel a bit like Dr Von Braun at the launch of Apollo 8. That is volcanic rock in there. Instead of welding the inner can to the barrel lid I used a hi temp epoxy for muffler repair sold in little jars at Auto Zone, along w/ strips of steel cut out of the barrel lid opening.

Good on your PCV/ charcoal canister purge line re-route! Plugs-I jumped up all the way to the stainless non-resistor Torquemaster's from Extreme Spark.com needed for the plasma spark deal. For Plasma the whole secondary side of the ignition needs to be zero resistancee or close as possible. Some radio noise and electronic interference does result, but my Subie engine just loves it! And believe me this little stodgy motor is a difficult test case to coax any more power from! And lately, the power output from it is improving nicely, it's like it needed time for things to clean out or change or adapt, I think.

Yes parts/stuff for interesting projects getting harder to find. I had to dig/scratch pretty hard to make this oven. Metal scrap yards around here wont sell anything, only buy! Thrift stores esp. low end ones can be a resource, never know what ya will find! Surplus stores, Free section of Craigslist are a resource. LOts of cool stuff just isnt made anymore, or only exists today new as a imported plastic version of itself. I've become a junk picker/hoarder and finder of metal things. I have a saying borne from experience that "stuff fits". An amazing variety of metal things and old cookware pots/pans fit together in an ever expanding universe of creativity. Oh, wait, they are coming to take me away again they are coming to take me away...

Hello Groovers
I have the gaskets for my 1997 chev (2 gaskets)and 1988 GMC pickups
I have found something about a failure of factory gasket for 1997 chev pickup TBI !!! The paper work at parts house says if any problem with gasket is seen when TBI is remove use this flat gasket not the one which looks like a rubber band on edge or just use the flat gasket anyway. If GM knows this is another problem with their product why will they not tell more about this problem ??
So my 1997 chev pickup will need 2 gaskets and a flashing made for reducing air intake wow
I have not worked on late model stuff but have a look at the 2 gaskets GMC has an opening between the intake holes wonder what is there ??
After reroutes on both trucks still running good no mpg to report yet

Have also found copper plugs, the paper work at parts house says all copper inside no resistors so will have plugs soon



GeraldC

You Gerald, yes factory and aftermarket fixes for design flaws are common. Just ask anyone w/ a GM V6 engine in mid 90's I think w/ black plastic intake manifold. That intake has the EGR gas routed through it w/ metal tube...the metal tube gets hot melts plastic and causes big trouble. So common that aftermarket plastic intakes for these are available w/ the fix built in.

So no surprize about the gasket gig...In the rush to implement ever more hi-tech in vehicles the OEM's sometimes make mistakes, or maybe it's just the bean-counters, or who knows.

cool that ya found non resistor plugs, w/gap increase should run well. watch out for radio noise and posibble ECM interference. The resistors are there to choke electronic noise in the RF range.

Just curious, does the '97 have port injection or TBI I would guess port inj.

Tracy G

97 chev has port injection

need a little help, I have been looking for the training videos on my 97 chev grooving. Ron had those done really good but somehow I can not find them now, maybe its just me but will someone point me that way, Please
Oh 1 st tank with rerouting of PCV and EVAP on 97 2 mpg gain

need a little help have been looking to buy a Fordham tool to cut the groove,, I think Ron said a T4000 but can not find or maybe I did not head or see right just need maybe a link or a name of the tool Thanks a Bunch
geraldc

Gerald, I think that's the Dremel 4000 you speak of, that's what I use along w/ the Dremel flex shaft, I hang the Dremel from a short legnth of shop lamp chain off the ceiling over my bench. Foot pedal speed controllers are around if ya wnat one look on ebay you plug dremel into it and pedal to wall.

Grooving the '97, look in your training DVD, also in the GM section in Index. There are several posts there re: this type TB. GM Tim from Redding did one I believe very similar to yours w/ pics posted. Watch out for a thin area of TB casting, have JB handy to build up near throttle axle area I think it was. Remember to "check your work" that's looking w/ bright flashlight from in/outside right at the groove to find any breakthroughs needing filling in. Don't worry 'bout those--part of Grooving!

A good idea if you're hesitant (or not) is post pics of the TB and we can chime in about it.

BTW; current score w/ rocket oven is: 2 pies, 1 bread, 1 turkey roast gonna try 2 items at once next.

have cut plug ground and gap to .074 platinum plugs,( reset computer per Ron's instruction ) on 97 chev pickup as a test 1st tank 320 miles run from Savannah to Atlanta Ga all flat run and runs great only gained 1 mpg, will be putting in copper non-resistor plugs this week

transmission was rebuild in 2003 with a dragster shift kit applied to valve body and has, at times, shifted with very hard jerk, no jerk at all now very smooth shifting

my rotary tool has came in so groove is top of list when I get home

I wish to find out what is put in or taken out of gasoline.... the difference between gas in Savannah vs Lilburn Ga. at Stone Mountain (emission test still done in Lilburn)
something is very different ---- gas bought at Koger both ends -- for years when I drove to Lilburn I filled up in Savannah and filled up in Lilburn to return home and always took less gas for return trip same miles oh and yes down hill if you can call this a hill (not) --- this return trip chev truck gained ---- 3.7 mpg-- to 16.7 mpg

these are copper non-resistor plugs gaped to .074 ,, will put them in chev truck soon the round gap tool is being used just to open gap the blade is good for gaping,, any one have any info on the gas difference ,, it may be just the difference between emission test passed and not tested
