Robby120113 Posted July 15, 2020 Share Posted July 15, 2020 (edited) Goodmorning all, SInce i have a nasty tick sound in my engine i inspected the valve lash and looks good. But i notice 1 push rod is bent and 2 push rods are not able to turn, i can move them byt hand just a little bit but they dont turn 360 degrees. Now i want to inpect them. I have a 1940 special so i asume i have mechanical valve lifters. Can i just remove the valve cover, make the valve lash bigger and push away the rocker and lift up the pushrod? Or will the valve lifter not come out together? I want to do the inspection toninght because a company needs to know the size of the pushrod so i can order them. Dont have many Buick parts in the Netherlands. Thanks all for the help! Edited July 16, 2020 by Robby120113 (see edit history) Link to comment Share on other sites More sharing options...
1939_Buick Posted July 15, 2020 Share Posted July 15, 2020 (edited) Download the 1942 Buick shop manual. All of it section by section. The pdf link does not work. http://www.oldcarmanualproject.com/manuals/Buick/1942/Shop Manual/ It is very comprehensive and has information that can be used with all straight 8’s. It has more information than was included in older “Shop Manuals” before 1942-41 You want pages 129 (6-13) to 131 (6-15) [section 07] Edited July 15, 2020 by 1939_Buick (see edit history) Link to comment Share on other sites More sharing options...
Robby120113 Posted July 15, 2020 Author Share Posted July 15, 2020 Hi 1939_Buick. Thanks, I did first read that part of the manual. I have this manual as pDF on my computer. But it didnt mention on how to remove them. Only about the backlash and timing etc. or i missed it twice now :X Link to comment Share on other sites More sharing options...
kgreen Posted July 15, 2020 Share Posted July 15, 2020 You can remove the valve cover and rocker arm assembly to then remove the push rods. The very last push rod won’t come out because of interference with the firewall. You’ll need to jack the engine around to do that. If you remove the lifter access cover on the side of the engine (behind the distributor), you can then lift the lifters out for inspection, too.

DonMicheletti Posted July 15, 2020 Share Posted July 15, 2020 If someone has worked on the rocker arms and shaft, whey can be assembled incorrectly. All the rocker arms are not the same. If done wrong, the pushrod will rub an edge of the hole it goes through, in the head, and bend (or break) the pushrod. Be sure the pushrod is centered on the hole. 1 2 Link to comment Share on other sites More sharing options...
Robby120113 Posted July 16, 2020 Author Share Posted July 16, 2020 Well. Yesterday i was totally freaked out. I have the car for a few weeks. But didnt expect this. What could have caused this?? I called the seller for help in this matter. 3 or so are bent slightly and three are bent to such extent the i cannot get the even out of the enigine. So have to bent them in shape a bit. Unbelieveble that the car still drove. Link to comment Share on other sites More sharing options...
Morgan Wright Posted July 16, 2020 Share Posted July 16, 2020 The problem is not the push rods. The problem is what the push rods are trying to push. Either your rockers are stuck or the valve guides are. Take the rocker arm shaft assembly out and see if everything is loose. It probably is. Now that you know the valves are stuck, take the head off and get it rebuilt. 2 Link to comment Share on other sites More sharing options...
Robby120113 Posted July 16, 2020 Author Share Posted July 16, 2020 @morganwrite hi. How is it possible that when i did all the valves backlash all looked good. I let the engine idle with the valve cover taken off. All the valves moved and nothing look wrong. Compression per cilinder is also still good. And driving went good except the extra ticking sound in the engine. Link to comment Share on other sites More sharing options...
Morgan Wright Posted July 16, 2020 Share Posted July 16, 2020 I wonder if maybe they have been bent a long time, maybe since before an old valve job when the valves were stuck. Link to comment Share on other sites More sharing options...
Robby120113 Posted July 16, 2020 Author Share Posted July 16, 2020 Indeed. I cannot find the push rods here in the Netherlands. And oldbuickparts also have no stock. So have the car for 3 weeks and already cannot drive it anymore for a period of time. Does anyone know an address that have these parts? Link to comment Share on other sites More sharing options...

This would be my guess as well. The car probably came out of storage, someone tried to start it without checking to make sure everything was loose, the pushrods bent because the valves were stuck, eventually the valves became unstuck, and then they reset valve clearances with the bent pushrods in place. Good enough to make it run, but obviously causing a lot of problems. Those are junk, you can safely cut them out of the engine and drop new ones in place. Call Doug S. at 440-835-1193. He will have a good set of pushrods for you. 2 Link to comment Share on other sites More sharing options...

raydurr Posted July 16, 2020 Share Posted July 16, 2020 If unable to locate a set you may have to have a custom set made. Look to Smith Brothers in Redmond Oregon . Perhaps they can duplicate what you need. 1 Link to comment Share on other sites More sharing options...
Mark Kikta Posted July 16, 2020 Share Posted July 16, 2020 I had this same problem on my 1939 Chevrolet. It was caused (twice) over 20 years from old gas making the valves stick. Link to comment Share on other sites More sharing options...
Guest Posted July 16, 2020 Share Posted July 16, 2020 11 minutes ago, Mark Kikta said: It was caused (twice) over 20 years from old gas making the valves stick. Actually the cause is the car sitting, sometimes for years. They were built to be driven. In the old days when people did not drive in the winter most cars started right up in the spring with no damage done. Today many cars sit for years and if they are driven they are not driven long enough or hard enough to keep everything free and clean inside. Drive them and they will almost last forever.

One problem with pushrods in 1940 is the firewall overhangs the back of the engine right over the last /rear pushrod which means you must remove the cylinder head only part way while pulling up on the push rod to get enuff clearane. More dtails later must sleep now! Link to comment Share on other sites More sharing options...

valk Posted July 17, 2020 Share Posted July 17, 2020 (edited) This is all too familiar to me. My ‘41 arrived to me when purchased with one broken and one bent push rod. Took me a while to discover. The engine had been rebuilt and the valve train looks new so I have no idea how this happened. The broken rod could be lifted out from the top when the rocker was loosened but I had to beat the bent one back straight enough to clear the cavity and be able to be lifted out the top. Got replacements from Bill (?) Tacheny who is a great resource. Edited July 18, 2020 by valk (see edit history) Link to comment Share on other sites More sharing options...
