Temme Posted June 11 Share Posted June 11 I recently purchased a 1929 Buick Business Coupe when going through the vehicle I discovered that the car has a badly cracked head that has been welded and still leaking antifreeze. So I am in need for a used head for this Buick any information would be appreciated. I'm attaching a photo of my 1929 Buick I want to keep it original if possible, it is to pretty of a car to give up on. 2 Link to comment Share on other sites More sharing options...

Temme Posted June 12 Author Share Posted June 12 I was asked to post some more photos of my 1929 Buick Business Coupe Series 116 Model 29-26. Purchased this car last fall was hoping to have some fun this summer going to some car shows but as nice as it looks I found some maintenance issues that needs to be fixed first. Maybe this fall or next year for sure. Thanks for all the help! 13 Link to comment Share on other sites More sharing options...

edinmass Posted June 12 Share Posted June 12 Nice car. Do a valve job and guides on the replacement head before you pull your old one off. Have a gasket kit handy also. Don’t knurl the guides…..it will smoke. Best of luck. Link to comment Share on other sites More sharing options...

Temme Posted June 14 Author Share Posted June 14 Tom Beautiful four door sedan! Edinmass thanks for the information I will follow your advice. First time I've ever replace a head on a vehicle before, plan on taking my time and learn in the process. Thanks everyone for the help!!! Link to comment Share on other sites More sharing options...
EmTee Posted June 15 Share Posted June 15 The valve job should include checking the gasket surface for flatness and truing it up if necessary. 1 Link to comment Share on other sites More sharing options...
edinmass Posted June 15 Share Posted June 15 If you need any additional help, send me a PM with your phone number and I’ll give you a call and can walk you through it It’s really a simple head to do The worst thing is picking it up over the fender I’m a big fan of finding a different head and rebuilding it so you can swap the head in one day it’s very easy to do 5 Link to comment Share on other sites More sharing options...
Temme Posted July 30 Author Share Posted July 30 Wanted to give a update with my 1929 Buick. I was lucky to find a replacement head for my Buick. Big thank to Bill McLaughlin for the contact information, which lead me to Tony and Joyce Bult. Thanks to Joyce and Tony Bult for their hospitality showing the wife and I around their shop, Tony's projects in which he restoring a 25 Buick Sedan, and a 25 Buick Speedster. Anyway I'm off the the shop tomorrow to have the Head reworked. 6 Link to comment Share on other sites More sharing options...

Fred Rawling Posted September 8 Share Posted September 8 BE SURE TO CHECK THE BLOCK TO SEE IF IT IS WARPED. A TRUE HEAD AND A WARPED BLOCK IS SURE TROUBLE. Link to comment Share on other sites More sharing options...
Temme Posted September 10 Author Share Posted September 10 (edited) More trouble with the Buick! Checked the replacement head it is flat the block is flat amazingly with what I found under the exhaust and intake manifold a big welded crack in the water jacket that is still leaking plus three other cracks in the water jacket. I will include photo's. I have pined three of the cracks in the water jacket but the welded area is too hard to drill. Researching on the web I ordered a Belzona 9111 repair kit, question has anyone had experience with this product? Any Suggestions?

edinmass Posted September 10 Share Posted September 10 I wouldn’t use the Belzona…………sorry for all your troubles. With stitching all the other cracks and a good used head, you may be lucky and have the weld hold. Another possibility is to just assemble the engine with the new head and gasket and pressure test it before you proceed. Remember you system is open vented so when running there is no pressure on the block…………if it’s seeping it will probably be fine. Many small cracks and flaws will often close up from rust over time. So running with just stright water and no additional additives may be an option over repairing or replacing the block. While not a professional or quality repair you may be able to get away with it. 4 Link to comment Share on other sites More sharing options...
edinmass Posted September 10 Share Posted September 10 Please post photos of the weld…….and let us know if it was leaking before tear down. 1 Link to comment Share on other sites More sharing options...
Temme Posted September 11 Author Share Posted September 11 From the stains on the painted block I would say it is leaking some water you can see the staining to the left side of the weld and I magna- fluxed the weld and you can see the crack line just below the weld on the left side. One positive is when I drained the oil I found no water. I will include photos of the welded area. Thanks for your input ! 1 Link to comment Share on other sites More sharing options...
edinmass Posted September 12 Share Posted September 12 I recommend another block…….or remove the one from the crankcase and have the weld cut out and then stitched back in place. Unfortunately, the never, ever weld cast iron rule is broken by way too many people with little to no experience. Until recently there was a stitcher who could easily fix that weld repair by unfortunately he passed recently and I am not familiar with anyone who I would trust that repair to……. 4 Link to comment Share on other sites More sharing options...
Hubert_25-25 Posted September 12 Share Posted September 12 I agree with Ed about pulling the cylinder section. If you can find a competent welding shop, they can fix the crack and you can reinstall the cylinder section. There are others on the AACA forum that have reported good success with rewelds on the water jacket. Hopefully one of them will chime in, or make a posting asking specifically about casting welders. Plan B is also to get another cylinder section, but then you get into needing pistons and rings. The wristpin is held with a bolt on the small end of the connecting rod on these engines. 3 Link to comment Share on other sites More sharing options...
edinmass Posted September 12 Share Posted September 12 To weld that block, it needs to be heated to 1200 degrees…….and it has a 80 percent chance of cracking again in that location. Also, with that much heat the entire block will need to be remachined every cylinder will have be punched out oversized……way too much money and risk. Stitching it is a good option……if a skilled guy can be found. Or find another engine and start over. All the choices are crappy…….unfortunately a common issue with dishonest sellers. Obviously the seller of the car knew what they were passing off………very sad for our hobby. 4 Link to comment Share on other sites More sharing options...
