1927 Tim Posted May 20, 2021 Share Posted May 20, 2021 I acquired a engine from a fella who died before he could complete his project. When I pulled the head, cylinder three had grooves in the side. Anybody got any ideas on why the grooves? Gas will just blowby. Thanks TIm Link to comment Share on other sites More sharing options...

I don’t know how the wrist pin is held in, that will need to be addressed as well Link to comment Share on other sites More sharing options...
Mark Gregush Posted May 21, 2021 Share Posted May 21, 2021 Wrist pins are held in place with clamp bolts, same as Ford Model T. Ether the bolt was left out or came loose allowing the pin to slide. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 21, 2021 Share Posted May 21, 2021 You may not need to sleeve it, just bore it oversize but then you should bore them all to match. On second thoughts it may be cheaper to sleeve one cylinder and not buy a set of new pistons, if the other cylinders and pistons are not worn. 1 Link to comment Share on other sites More sharing options...
1927 Tim Posted May 21, 2021 Author Share Posted May 21, 2021 Thanks to all ! Now I have to find a good machine shop that can do that in Texas. Link to comment Share on other sites More sharing options...
rocketraider Posted May 21, 2021 Share Posted May 21, 2021 Find one familiar with tractor and industrial engines. Lot of those have sleeved blocks. Link to comment Share on other sites More sharing options...
chistech Posted May 22, 2021 Share Posted May 22, 2021 Find a 28’ engine. Two exhaust port head and aluminum pistons. 28’ engines are the best prewar four cylinder chevy made. 1 Link to comment Share on other sites More sharing options...
Flivverking Posted May 25, 2021 Share Posted May 25, 2021 If your looking to rebuild the entire engine this is not really an issue , just write the $4,000 to 6,000 check. If your looking to do a good old fashion back yard service overhaul ,you may just repair the one cylinder with a sleeve and have it bored back to what ever the pistons are now ,if that piston is reusable and fit a new wrist pin etc. Some bore honing ,new rings across the board ,some valve grinding and bearing fitting. You may very well get several thousand more miles out it. True up the clutch works for good measure. 1 Link to comment Share on other sites More sharing options...
Larry Schramm Posted June 1, 2021 Share Posted June 1, 2021 For an engine rebuild, usually consider about $1,000-$1,500/hole(cylinder) 1 Link to comment Share on other sites More sharing options...
stakeside Posted June 5, 2021 Share Posted June 5, 2021 To get it right I went with full rebuild for DA6. I felt that my truck required it since all work put in to restore it. With new sleeves, Babbit bearings, pistons and misc machine work cost was $8000. Right on Larry. Link to comment Share on other sites More sharing options...
Mark Gregush Posted June 5, 2021 Share Posted June 5, 2021 The Filling Station Chevrolet parts Do a little price shopping on parts and labor cost, I know darn well if you can turn a wrench and know something about rebuilding engines you could do the work for a lot less then suggested above and maybe learn some new skills in the process. Think about how much you are going to use the car; Few hundred or less miles or few thousand miles a year? Are you going on cross country tours or just putting around the neighborhood? Even if you sold it later, chances are the next owner would not be driving a major miles ether. 1 Link to comment Share on other sites More sharing options...

The numbers that I state are for a good machine shop to do the work to make it a "long block" engine rebuild. If you are going to do just a re-ring, insert bearings and a valve job and you are going to do most of the work yourself, probably can be done for less than $1K. 1 Link to comment Share on other sites More sharing options...
stakeside Posted June 7, 2021 Share Posted June 7, 2021 If I could have used bearing inserts for six cylinder engine my rebuild costs would have been around $4000. I preferred to have a shop do the long block rebuild. Link to comment Share on other sites More sharing options...
Mark Gregush Posted June 8, 2021 Share Posted June 8, 2021 Guess after looking at the current Filling Station Catalog, in the last year they have lost a number of parts suppliers for pistons and semi finished mains. But no fear, except maybe the pocket book on the mains; Kohnke Rebabbitting Service | Facebook Is the DA6 a Dodge and didn't they have insert bearings on the mains? 1 Link to comment Share on other sites More sharing options...

They are placed in form and babbit is poured. Once done they are placed in block and line bored. 1 Link to comment Share on other sites More sharing options...

Your $14K is close, plus there were more hard parts added. 1 Link to comment Share on other sites More sharing options...
