1951 Pontiac Chieftain - Cherry Bomb

Recommended Posts

Last night I didn't have the energy to do anything in the car in the heat after mowing the yard so I sat down and started looking at exhaust stuff.

Most of the pipe backwards of the muffler looks like this, including the muffler itself. 

The muffler is huge, 35" long, 5" round with a 2" inlet and a 1 3/4" outlet.

I'm thinking of replacing that with a glasspack and renewing the rest of the exhaust to the back in 2".

It's like a six with more of a warble.

 

It was backing out of a few cylinders at the end, too much throttle on a cold engine. It picks up properly once it's warm.

Better yet, found a place that will bend a new section to size.

Doing it in 2", it'll be that size from the manifold to the back barring going through the muffler at 2¼".

They reckon about $50. Jumped at that. Got there at the end of the day so they're keeping the old pipe as template and will call me either tomorrow or Monday depending on how busy they are.

10 hours ago, somewhatfoolish said:

Dry sand, two wooden bungs and a mahoosive blowtorch. Or a mandrel bender.

I remember doing that 30 odd years ago on my YTS at college. That was with the thick wall mild steel pipe though.

      Morning chaps, long time no see.
      I've not had much in the way of shite to share on this forum of late but I have now gone some way to redeeming myself with this glorious old heap, an eBay purchase which I won last night.  Fortunately the seller seems decent and isn't in any rush for it to leave so there won't be much happening for a  few weeks until collection can be arranged, leaves me plenty of time to clear the decks in preparation.
      The essential stats are that it's a 1977 Princess 1.8, I think it's a base model and a Series 1 given it's not got a 1.7/2.0 O-series engine which I would have preferred.  Not sure how rubbish the B-Series is in this thing but I guess we'll see.  It's got an MOT and has been woken from many years of slumber fairly recently, I think it was on eBay last year prior to the current owner obtaining it but I don't have any details.  I think it's a base model and lacks power steering or indeed any equipment to speak of.  It's apparently very solid and has been undersealed, there's some rot above the bootlid and in the doors and the bonnet looks awful but is mostly surface corrosion I think.  It'll be getting a proper going over once I get my hands on it, a full service and brake refurb is likely the first port of call, plus finding someone local who can pump up the hydragas.
      My sole experience of these is driving Philibusmo's utterly ruined example (OKK if anyone remembers the ex-Vulgalour one) a few years back and I was so impressed at how well it drove considering the state it was in, I've wanted one for years so this is a slightly weird dream come true.
      Feel free to chip in with anecdotes, advice and mockery.  More details will probably surface in a few weeks once it lands.  It has MOT but it's on ancient tyres and has electrical issues (I know, who'd have thought?) meaning the lights and cooling fan don't work.  Given that it's in Kent and I'm in Devon, I am probably going to take the easy way out and Shiply it home.  Plenty of time yet to make some arrangements for that.
      Watch this space.

      Well I've been meaning to sign up here in forever, but kept forgetting. Thanks to someone over on another forum I frequent poking me about it recently the subject was forced back into my very brief attention span for long enough to get me to act on the instruction.

      I figure that my little varied fleet might bring you lot some amusement...

      So...we've got:

      1993 Lada Riva 1.5E Estate (now fuel injected, as I reckon the later cars should have been from the factory...).
      1989 Saab 900i Automatic.
      1987 Skoda 120LX 21st Anniversary Special Edition.
      1985 Sinclair C5.
      2009 Peugeot 107 Verve.

      Now getting the photos together has taken me far longer than I'd expected...so you're gonna get a couple of photos of each car for now, and I'll come back with some more information tomorrow when I've got a bit more time...

      Firstly...The Lada. Before anyone asks - in response to the single question I get asked about this car: No, it is not for sale. Took me 13 years and my father's inheritance to find the thing.


      Yes, it's got the usual rusty wings...Hoping that will be resolved in the next couple of months.

       






      Next, a proper old Saab. One of the very last 8 valve cars apparently, and all the better for it. I've driven two 16v autos and they were horrible - the auto box works sooooo much better with the torque curve of the 8 valve engine. Just wish it had an overdrive for motorway cruising...









      Next up a *real* Skoda...back when they put the engine where it belongs, right out the back. In the best possible colour of course...eye-searingly bright orange.







      Seat covers have been added since that photo was taken as it suffers from the usual rotting seat cloth problem that affects virtually all Estelles.

      Then we have possibly the world's scruffiest Sinclair C5...



      Realised when looking for this that I really need to get some more photos of the thing...I use it often enough after all! We have a dog who's half husky, so this is a really good way of getting him some exercise.

      Finally - again, I really need to take more photos of - we have the little Pug 107.



      Included for the sake of variety even if it's a bit mainstream! First (and probably to be the only) new car I've bought, and has been a cracking little motor and has asked for very little in return for putting up with nearly three years of Oxford-Milton Keynes commuter traffic, before finally escaping that fate when my housemate moved to a new job. Now it doesn't do many miles and is my default car for "when I've managed to break everything else."

      I'll fill in some more details tomorrow - I warn you though that I do tend to ramble...

      As tradition dictates, an thread.
       
      It all kicked off here: http://autoshite.com/topic/34152-citroen-bx-17rd-for-sale-sale-on-hold-as-its-done-a-citroen-the-little-bastard/
       
      Lorry is booked for collection tomorrow and a 340ish mile round trip awaits.  It will be a long, but rewarding, day.  No live collection updates because I live in the olden times and even if I didn't, I'm not sure I could be entirely arsed.
       

       
      I am looking forward to meeting Dean-numbers, his collection of wobbly French cars and, of course, Bleriot the BX.  It will probably be too dark to do anything when we get back on Friday so I suspect Saturday I'll be up bright and early to get stuck in and see just what I've let myself in for.

      That bit hiding up behind the air filter and infront of the turret



      made a prolonged, loud, farty vibratey noise (loud enough to be clearly audible in the cabin with the radio on) twice today, both times it did it the nose was pointing down a steep hill and we had just parked and turned off the engine.

      It goes on for best part of a minute, so managed to track it down. Initial impressions are fuck knows what it is but it's clearly been bodged in the past. The yellow hose has clearly been disconnected sometime, by someone, for some reason, somewhere.



      Thats the blighter.

      Does someone want to tell me why it's blowing raspberries at me?
