Guest 22Coupe Posted October 26, 2012 Share Posted October 26, 2012 What are the preferred spark plugs to use in the 4 cylinder engine? Should I use the long reach plug or not and what should the gap be?Also, what gear oil should I use in the rear end and the transmission? Is 600W recommended for both?I appreciate any advice, Thank you Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 26, 2012 Share Posted October 26, 2012 You can use the same type as on A-Ford,those plugs on Ebay are short enogh for putting the spark plug cover on without problem,thread 7/8" 18.

Brian_Heil Posted October 26, 2012 Share Posted October 26, 2012 Agree the Autolites run the hottest/cleanest. Be careful, these modern plugs are longer externally than the orginal plugs and the external electrode will ground to the sparkplug cover unless you take right angle spark plug boots and slit them down the inside angle on one side and slip them over the plug and wire end.

Leif Holmberg Posted October 26, 2012 Share Posted October 26, 2012 Those plugs are used on my friends 1927 Buick Std. and works fine without any wire end covers,and he has the spark plug cover on place .I think those plugs are one of the shortest to buy.

Brian_Heil Posted October 26, 2012 Share Posted October 26, 2012 Could be Leif. I'm running 3078's (hotter) and not sure how long they are externally compared to the 3076's but on a 1923 6 cylinder the 3078's do jump spark (ground) to the installed cover.I did once see the original Titan brand original plugs and they are very sort externally so this was not an issue years ago.

Guest 22Coupe Posted October 27, 2012 Share Posted October 27, 2012 So, no one has tried the 3077 long reach spark plugs? For those of you who have used the 3076 plugs, what do you gap them at? The engine currently has Champion W16Y plugs in it and they are gap at .020-.023Does that gap sound correct?Thank you for any help Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 27, 2012 Share Posted October 27, 2012 .020 looks right,but I always wonder when people ask those questions why don`t they buy a book or manual for a very small amount comparing to what the price on the car is.About the plugs,I think you can use a lot of different plugs but be sure that they are not to long to destoy the piston.

Guest 22Coupe Posted October 27, 2012 Share Posted October 27, 2012 Leif,The car was a recent purchase and I have not gotten around to locating a manual yet, but will do so. I was curious as to what other Buick owners were doing. Also, wondering how many of these cars are around as parts seem non existent?Thank you for your help.

Leif Holmberg Posted October 27, 2012 Share Posted October 27, 2012 22Coupe,You never told what type you have,is it model 36 4 cyl.or model 46 6 cyl. Leif in Sweden. Link to comment Share on other sites More sharing options...
Guest 22Coupe Posted October 28, 2012 Share Posted October 28, 2012 Leif,It is a Model 36 4 cylinder. All original brochures I have seen say it is a 2 door 3 passenger Coupe. I can't see how 3 passengers could possibly fit? People back in the day must have been small people! With my wife and I there is no room for a third person. Anyway, the car is a lot of fun to drive!Cheers Link to comment Share on other sites More sharing options...
jbbuick22 Posted October 28, 2012 Share Posted October 28, 2012 This system does not have a air gap in the dist cap The air gap lets the coil voltage to get higher and will fire the plug with a hotter spark, opening to plug gap to 035 to 040 will will make the spark hotter.See Dave Chambers article in AA March - April 1971.

Leif Holmberg Posted October 29, 2012 Share Posted October 29, 2012 22Coupe,I was wrong I gave you the gap for Braker Point in stead of the spark plugs.Breaker Points is as approximatly .020 and the gap on spark plugs are approx. .025 Leif in Sweden.

Brian_Heil Posted October 29, 2012 Share Posted October 29, 2012 Dave Chambers (famed 1920's Buick expert) did an article in (I think) an AACA publication years ago where a dyno study on gap was run and found 0.035 inch made the most power. I've seen re-prints of the very good article several times and wish I had a copy. Based on the article, I agree and have been running 0.035 for years with as hot a plug as I can find. This is not a 'fix all' change. Everything else has to be in good order also (coil, condenser, points, cap, wires and their connectors). Perhaps someone has this article?The other change is base timing change which i have reviewed on this forum several times. Link to comment Share on other sites More sharing options...
jbbuick22 Posted October 29, 2012 Share Posted October 29, 2012 The article y Dave Chambers is available from the AACA lib. as a reprint, The original Antique Automobile shows up on EBAY (March-April 1971) . Link to comment Share on other sites More sharing options...
Guest 22Coupe Posted October 29, 2012 Share Posted October 29, 2012 I originally found the plugs were gaped at .020 which looked to small to me (engine running). I increased the gap to .035 and it looked unnatural to the plug so I decreased the gap to .030 and the engine would not start. I decreased the gap again to .025 (looked more appropriate) and the engine fired right up. A little food for thought? Link to comment Share on other sites More sharing options...
Dave_B Posted October 29, 2012 Share Posted October 29, 2012 By the way, the Autolite 3076 plugs are often available in your local auto parts store. I buy them at Advance Auto right off the shelf. Dave Link to comment Share on other sites More sharing options...
Guest 22Coupe Posted October 31, 2012 Share Posted October 31, 2012 Does anyone know the model number of the correct Stewart vacuum tank for the 1922 Buick 4 cylinder engine? The tank is missing on my Coupe. Likewise, if someone has the correct tank for sale?Thank you for your time Link to comment Share on other sites More sharing options...
Leif Holmberg Posted October 31, 2012 Share Posted October 31, 2012 1921 D,E,H,K 6cyl.=122-A-----1922-1923-1924 4cyl.=122-AB------D,E 4cyl.=122-H----------1924 6cyl.=208-A------------1925-1926 Std.=215-A-------1925-1926 Master=216A----------1926 Std.1927-1928 ser 115.=216-T---------1926 Master,1927-1928 ser.120-128=216-U,The last ones it`s not quite right I think, becuse I sold a 216-X today and I think that was for a 1928 Buick as well.

Guest 22Coupe Posted November 2, 2012 Share Posted November 2, 2012 Leif,I have both the reference book and manual are on their way.A question I have right now is: There is a little oil leakage from the right rear axle seal onto the brake shoes (from what I can tell from underneath). Is there a puller I need to get the hub assembly off? Would you know the size of the puller? Also, what type of axle seal will I need to find (or make)?Again, Thank you for your help.
