    Steering gear/ Pitman Shaft Seal

    in Buick Riviera

    Posted

    I've replaced just the pitman seal with unit in car. Looks like you also have a leak at the end cap which is just a large oring behind the cap which is held in place with a spring ring. Go to RockAuto.com and drill down through and you will see pic of the pitman seal.

    I am sure it is just me, but I read this ad and think, this doesn't sound like an original owner ( who would be at least 70 years old), sounds more like a guy bought it from the original owner and is flipping it.

    1968 Buick

    fuel: gas
    odometer: 65000
    title status: clean
    transmission: automatic

    Spring is here! Be the talk of the show with this Original Owner 1968 Buick Riviera!

    With it’s extremely low mileage of 65,000, and only 1 owner it’s whole life, this Riviera was very rarely driven! It runs and drives excellent. The vinyl interior has no rips, stains, or tears. Power windows, power locks, power brakes, power steering, 430 V8 7L engine, air conditioning, tilt wheel, delay wipers, hideaway headlights, etc. 
     

    Agree not original owner, at least writing the ad anyway. Power door locks and delay wipers.....things that make me go hmmm.

    that was what I was thinking too, so I had to buy it.  Once I get it next to my red one I will figure out which one I like better and what my next steps are.  

    Chris, let me know if you need assistance in decision on which one to like best.....but you probably already know what I would say so its rhetorical I suppose. Congratulations! Amazing that cars this special still turn up and were previously unknown.

    430 rebuild: rear rope seal problem

    in Buick Riviera

    Posted

    In the case of bearing clearance, I would only trust plastigage because it shows precise clearance after torqueing the bearing cap to spec. Yes one can base clearance using stock rod/bearing specs and how much the crank journals were cut down, but humans make mistakes as well as bearing manufacturers. Plus, unless measuring instruments are calibrated, do you want to trust their accuracy to such a critical part of engine build? Not me!  Plastigage verifies the theoretical clearance.

    How would one accurately measure the ID of a connecting rod with the bearing cap installed and bearing shells in place? 

    Seal installed or not, it won't have effect on bearing clearance check.

    430 rebuild: rear rope seal problem

    in Buick Riviera

    Posted · Edited by JZRIV (see edit history)

    Would not use rope. The "One-piece" rear main seal in this link is what I would use.  https://www.bopengineering.com/buick_v8.shtml

     

    Also if you haven't already, plastigage your rod and main bearings and record readings for a baseline. Yes it will take time but if you have have a problem when engine is started, you'll have confidence bearing clearances are not the issue.

    Degree a Camshaft - Stock and After market

    in Buick Riviera

    Lower performance in rpm range vs what it was designed for. Vacuum can also be affected. Many variables play into it though. Typically on a stock cam installed straight up you may not notice in seat of pants feel if its off a couple degrees. The more one is seeking high horsepower, the more important it is to degree it. In my opinion its wise to take the time to check/verify it when assembling the engine no matter what. If you get the engine together and have a problem, you will always wonder if cam setup is the root cause. If it was degreed, then that can be crossed off. Its no fun pulling engine back apart after the fact.

    New to Rivieras...looking to get my first...starting research

    Welcome to the forum MrMajstyk. The floor mounts for seats in the 65 can be extended rearward with basic fabrication skills. 2-3 inches works for most. Doubt you'll have a problem with the 71/72.

    Generally the center support bearing and mount needs replaced only once on 1st and 2nd generation Rivs and majority of time its because the rubber dries up and breaks apart.

     

    Love that 68 Caddy with the stacked headlights. Those are awesome cars. I had a 70. Join ROA if you haven't already. You'll get access to a searchable index of articles from 39 years of Bi-monthly magazines among other benefits.

    How many coats coating are necessary to protect paint for a reasonable length of time, please?

    Do you mean putting clear over old paint?

    hey Jason, that is a beautiful Riv. First time I ever noticed the unusual trunk hinge design on a '66. Q: where does the water go after entering those wells that house the hinges?

    EmTee what you have circled is the gas tank vent loop. They looped it into the trunk high above tank no chance of fuel spillage at any angle......other than upside down. LOL. One end of pipe is connected to tank via hose and the other end is left open to atmosphere near rubber grommet where it exits back out of trunk. Big wide open vent as far as gas tank vents go. This vent can get clogged when car sits idle outdoors for long periods from mud dobber type wasps but I digress.

     

    Yes the drains are unusual but very effective. I've never had them get clogged to where water would back up. Its a very special hose that dumps out above axle. Probably 1.5 or 2" in diameter. The exit end of hose has a very thin rubber flap valve of sorts that lets water out but nothing in. Similar to what you might see on drain boots for older vehicle A/C systems. That hinge cavity is also open to the rear cowl vent (screened) below window.

    Thanks for the info JZRIV. My material came up in pieces. No way to use it for a pattern. I have a 618-D build date. Tried to send NC1968 Riviera a message, but since I'm new this is what the site sent me...Your account has not yet met the minimum content item count requirement to send personal messages. Not quite sure what that means?? I checked the rules and don't see that mentioned. 

    This is typical for many forums. They require a few posts and or replies before allowing private messaging. Believe this is to help control spammers. When you say you joined the "club" do you mean joining the forum here or the Riviera Owners Association? Once you join ROA you should be able to get the login info to view the Bimonthly magazines digitally until your hard copy arrives. There are many sources for used and reproduction parts in the classified section.

    618-D is the interior trim code. Build code will be on top left of Fisher tag. Here is a pic of 66 trunk

    Check with Jenkins Interiors in NC if you want the original type tan weave material. I bought the last original NOS material they had several years ago but pretty sure they reproduced it since then. I hope enough of your original material is intact enough to use as a pattern because they only sell it by the yard.

    66 Rivs had 3 different trunk patterns depending on build date. Early builds had tan weave material with 1 piece floor section (not cut out for the spare tire cover). The majority of cars had tan weave with the spare tire cover cut out. Late production June 66 went to the black with gray fleck used through 1970. At the this time they also changed the cardboard from gray to black/gray flecked. Gray cardboard was used with the tan weave lining which is not available. Need to purchase black cardboard kit and paint gray if you want to maintain original appearance.

     

    The black trunk lining is available in kit form by a member here on the forum. NC1968Riviera and also advertises in the ROA Riview classifieds

    SF engine code in '71 Riv GS?

    in Buick Riviera

    Posted

    Never a stage 1 emblem on grille of 71 GS. NTX is correct on the codes. 71 GS is TA code. So much misleading internet info on this. The 71 GS engine had bigger valves but did not have the cam, carb, distributor, etc of the famed high HP Skylark-bodied Stage 1 Optioned 455 cars. Without the TA engine you'd have to do some more homework to make sure its an original GS. It could be but who knows. It wasn't uncommon even back when these cars were only 2-3 years old for people to put GS emblems on a non-GS car because that's what they really wanted, but didn't buy. Even more common in the last 25 years.
