rodneybeauchamp Posted October 10, 2017 Share Posted October 10, 2017 Hi, just a simple one. Can someone advise the correct oil pan drain plug washer size ( inner and outer diameter and thickness) on the '63 Riviera 401. When I drained the engine oil for the first time, I never had a new one, so reused the old one. The one I removed was a thin nylon material, but unsure if this is correct for the motor. My jobber store in Australia may have them, but I need the specifications. What do you guys and gals use? Link to comment Share on other sites More sharing options...
telriv Posted October 10, 2017 Share Posted October 10, 2017 If it has the original size drain plug it will be 1/2". Next time you change your oil take the drain plug with you to the parts store & match it up to a copper style drain plug gasket. Link to comment Share on other sites More sharing options...
68RIVGS Posted October 12, 2017 Share Posted October 12, 2017 Copper type seals get crushed after the first application, and may leak each time they are reused there after ! The nylon type washers are more durable, and can be reused without any leak problems. Simply match the nylon seal to the corresponding surface of your oil pan plug. . . . it's not exactly rocket science Rodney ! 1 Link to comment Share on other sites More sharing options...
rodneybeauchamp Posted October 13, 2017 Author Share Posted October 13, 2017 Thanks Randy, my dilemma is that I have already changed the oil and put back the old washer, so no chance to match the old one. Besides, in Australia much of what we now have is metric so I really need a sample. Also, I was uncertain as to whether the PO used a correct washer. At this stage I have a nos plug and washer being posted out, so I should be able to match it. ? Link to comment Share on other sites More sharing options...

The exception has occurred on this part. I gave up trying to find the right one so I made my own from cork/rubber gasket sheet goods. It wasnt pretty, but it stopped the drip.

rodneybeauchamp Posted October 23, 2017 Author Share Posted October 23, 2017 Hi RRB, i was very fortunate that I found a NOS/ONS plug and washer through this forum. And even better is my local parts store had the washers which were very close to the originals. My problem was the PO had used a nylon washer which I guessed wasn't correct but wanted to make sure. I agree, sometimes making your own is the best course. I'm doing that now with some of the exhaust pipe hangers by renewing the rubber component as I want to maintain the original brackets. Sure they will use a nut and bolt instead of a rivet but the rest will be the same. Better than using a universal fit hanger that is nothing like the original and often inferior. I certainly enjoy the challenge of refurbishing rather than replacing. Rodney 1 Link to comment Share on other sites More sharing options...

Rodney, now I'm on the task of replacing the clips that in the hub of the center cap assembly for the cast aluminium rims for my 63. The reason for replace as there are no clips in the hub. The metal thickness measures to a 20 gauge metal. It is a simple replication and a single riviera attachment. When I get some pics I'll send them to you. I believe I enjoy coming up with a solution rather than going unnecessary expense. Believe me, I do not confuse costs with economic considerations. For example, a new purchase could be less expensive than my home made solution. Oh, when it comes to exhaust hangers what ever it takes to keep the system from rattling gets my dollar.

Rodney For your new exhaust hangers, check out using tubular rivets rather than nuts and bolts. 1 Link to comment Share on other sites More sharing options...

I need an extra plug and washer and would like to buy what fits first time out. Thank you for the tip on the door jam switch and a source to have it fixed. many thanks, RRB Link to comment Share on other sites More sharing options...

Paul K. Posted June 12, 2018 Share Posted June 12, 2018 If you reuse your drain plug washer and you feel it may leak, a thin layer or RTV on the sealing surface will get you by until the next oil change. Link to comment Share on other sites More sharing options...
