Toasted Exhaust Manifold 292 I-6

[vwnate1]

Customers are always asking me why they should fix a leaky exhaust gasket as it ' kinda sounds cool ' or other dimwit thing .

I just took my '76 GMC's manifolds off and it's been many a year since I saw one this badly cracked and warped both , it appears it was driven like this for years and years...

The guy who sold the truck to me , said " I fixed the exhaust to sound like that " ~ not bloody likely .

And so , the hunt begins .

Anyone got one ? .

I didn't think the detail was good but you can clearly see it is cracked and broken every which way but good .

Not so visable is the fact it's warped about 1/8" !

No way I can patch this junk .

Getting There.....

Bit by bit ~ I stripped off most of the engine accessories and began scraping & de - greasing , it's almost ready for paint .

Next Fun Bit : WIRING

Here we have Medusas hair ~ oh wait , it's the remanants of the underhood harness...... ... note the unecessary splices every 6" or so and color changes in the wires .

I hope to find another one in the junkyard soon and make up a nice new correct one .

been there, done that, got the tattoos, scars and the 't' shirt .
yep it's worth it.
Some times finding wrenches isn't so fun.
Keep up the good work!!!!

' Finding Wrenches '

Oh ,that part's not too bad , I just look around the driveway , I prolly kicked that one I need under an old engine .

Interestingly , I found a great place to buy NEW exhaust manifolds , old timey rams horn ones up to new import ones , they have the 194/230/250/292 ones too but said the last batch didn't pass the quality control inspection so they sent 'em all back , I found three in a dealer in Fla. and hopefully one is now inbound as you're reading this .

I'll post up the exhaust manifold places' info from work next week .

I _know_ it'll be worthwhile , I'm a farm boy who grew up on pre war InLine 6 Bangers unlike most here ~ I don't own a modern car (WARNING : GEEZER RANT MAYBE NEXT ) as life is far too short to waste driving a tincan with wheels or another (yawn) SBC powered lump .

Living in L.A. (home to fruits , nuts & flakes) is good too as we have more cars , trucks and Motos than Detroit EVER did ! you'd be flabbergasted at the cherry 1989 C-20 I saw in the yard to-day , it has a new carby (2BBL) on it's 350 , no dents , shiny paint etc. , etc. ~ I have NO IDEA why it was junked but I hope those *perfect* hood hinges are still there when I get there if not , no worries , there'll be plenty more , I'll just have to wait .

Wow oh Wow three years ago I had a 84 with a lot of 6 parts you would have liked I had it all most a year carb nice, fuel pump was pretty new, HEI dist good. It hard to find some one that want the 6 parts. So I left
them on shame on me. I think I have the bracket for the PS/ Alt I was in one of the posts I guess the guy did not like the grease and dirt on it I tryed to get the parts off get pic to him sooner he did want it So I clean it for nothing . Keep up the good work .

I-6 PS Bracket

Well ;

if you still have it , please send me a picture OFF LINE as the DPM cranked some Metric bolts into mine so it now has stripped out captive nuts , I am making - do with slightly longer bolts and nuts & washers added , yes it's a 100 % repair and will work fine but it bugs me , knowing it's there ...

Anyways , Sunday I went way out to Bloomington , Ca. and found ,much to my delight , they were having a 50 % off sale at the P-A-P plus several (like 20) '73 ~ '87 trucks including on base model 1976 Chevy C-10 so I loaded up on little detail things , grabbed an almost undamaged underhood harness , lots of those little plastic loom holders , some un rotted (if filthy) plastic loom , an original battery hold down clamp and even a nice recently re-chromed front bumper ~ all this for $50 and they GAVE me the two 1977 light duty truck owner's books and gas caps , horn button & lotsa other little bits like that .

Toobad I foolishly forgot my sun hat and the correct tools as I spotted several clock options and I'd like to add one , being quartz , they'll never stop working nor loose time .

I'll try to attach some pictures here :

New Exhaust Manifolds I-6 230/250/292

THANX ! .

I did find one in an East Los junkyard but then I found a new one in Fla. and ordered it in , it's made by ATP and it's also on back order because the supplier send them a whole container full of bad ones , they didn't pass their Q.C. inspection , I was lucky to find this place in Fla. that had a few older , good ones on the shelf .

It arrived thursday late and I picked it up Friday morning about 04:30 and as soon as the sun came up I opened the box and had a look , it looks good (pix when I get back from vacation) , is made in where else ?) China , has the GM late production re-design so it can be used with either two or three studs ~ this has the added benifit of thicker metal in the outlet flange area ~ I'm hoping it'll work well , maybe I can install in Monday .

I'l provide the supplier info if you still need one , it's a bit more $pendy though ~ about $225 delivered , it comes as a kit with gaskets and new studs too .

Or , I could go look at the junkyard one near me for you if you'd like ~ my intake is pretty beat up so I might be buying that anyways , I suggest waiting
until you know how well this Chinese one works on my truck .
