    Coolant and Spark Plug gap questions.

    This is precisely what I was after - I wondered if there was a simple and cheap test available to determine if this was the OAT or HOAT formulae; I bought this car from the son and heir of the original owner, they took remarkable care in most aspects of the maintenance - although the son thought...

    Coolant and Spark Plug gap questions.

    As I recall - '75 was the first year - at least in this part of the world - for HEI across the board, and the big gap was a hope to reduce n0x emissions ('X' suffix). The pressures are fairly high - but the ratio is quite low, so I should be able to advance the timing to 'what the motor wants'...

    Coolant and Spark Plug gap questions.

    I need some advice on adding/replacing coolant for my 1975 Pontiac Parisienne (‘Cheviac’) and a plug gap query. I have a weep in the passenger side rad tank fitting that receives the upper trans cooler line flare nut; the rad has to come out to re-solder the female fitting; when I complete the...

    Oil leak

    A bit late but ~ the Oil Pressure Sending Unit is at the back on the driver's side, if it is leaking it will cause a heck of a leak when the motor is running and can look like a leak from the driver's side valve cover.

    Weird no start

    ECM will prevent starting if it does not sense a pressure signal from the OPSU (in later TBI applications) - chewed, burned/damaged harness or tired OPSU; might be the case here.

    Engine cuts out - cranks, no start.

    Good information - I usually drive to the A/C Delco jobber about 20 minutes away - I like the staff, they take the time to research bits for my Antiques Roadshow. There are some Autozone stores down along the border ( about 6 hours away) and I will look at ordering parts from the US site - and...

    Engine cuts out - cranks, no start.

    I purchased the Spectra HEI GM 14 from amazon ~ despite the poor value of our dollar it was very inexpensive; it took many week for it to arrive and that, in part, explains the lateness of this post. After two weeks of road testing it has passed with flying colours - the box is marked " Made in...

    Engine cuts out - cranks, no start.

    SirRobyn0 Thanks for the link - I had been to that page, saw the OBSOLETE but the "Part 8CYL/CCW-HEI" did not sink in - 1103357 may indeed be for a boat - however it has a vacuum advance, something I thought was impractical in a marine application - any road I will call Spectra tomorrow to...

    Engine cuts out - cranks, no start.

    @bucket @SirRobyn0 Every bit of opinion on aftermarket parts that I get from this forum is a bonus - I have had some frightening experiences over the last couple of years with 'white box' parts that have spooked me. Spectra products are very common up here ( my rubbish bins are Spectra's) I...

    Engine cuts out - cranks, no start.

    Thanks, I have a spare non-ESC distributor somewhere - I will dig it out and see if I can find an application on the net - it was supposed to be for a boat but I doubt it, any tips on installing a "Street Fire" ? It will be about $300 bucks here, I can get a Taiwan special "Spectra Premium...

    Engine cuts out - cranks, no start.

    1981 GMC C 1500 2WD 305/350THM engine code H. Would not restart when hot (ambient temperature 110 plus) – no tach when cranking hot, 20 minutes of engine cooled down and it started and ran fine. I had an aftermarket replacement coil so I installed it while waiting for the Standard ignition...

    Detent Cable

    Thanks, you sparked an old memory! I might adjust the free-play on the cable if required - after I get my new tires; if the trans will kick down at 80, I will not twist my old spine.

    Detent Cable

    Very common repair, exhaust stove heat is very important in this part of the world.

    Detent Cable

    You answered the question - I have not seen this before, or never noticed it. Thanks.

    Detent Cable

    I have a 1975 Pontiac Parisienne – one of the “New for ‘71” bigger better GM B bodies that ended in ’76. As it is a Canadian Pontiac it has a Chevrolet “Power Team” (we used to call them Cheviacs/ Caprisiennes etc.) it this case a SBC 400 Qjet (orange motor) and M38 THM 350 CBC. It has some...
