RivNut Posted November 20, 2019 Share Posted November 20, 2019 My 64 Riviera 425 has a slight ridge like yours. The mechanic who does the big stuff for me suggested that I borrow his ridge reamer, remove the pistons, and run a hone up and down each cylinder a couple of times. Put new rings on the old pistons and new main and rod bearings in it. The heads are done. He then said bolt it back together and enjoy driving it. I'm not going to put a 100,000 miles on it and financially it's not worth going whole hog. 4 2 Link to comment Share on other sites More sharing options...
old-tank Posted November 20, 2019 Share Posted November 20, 2019 Reaming the ridge should only be done by someone with experience or under their supervision. I have seen some that could have been done like RivNut that were overcut below the ridge and would not clean up with even a 0.080 over bore...engine ruined or now needing sleeves. 2 Link to comment Share on other sites More sharing options...
Kosage Chavis Posted November 22, 2019 Author Share Posted November 22, 2019 I do plan on doing an ambitious job on this engine. First, I want to become an expert with these engines at some point during this process. I know that means doing most, if not all of the work on this engine. Obviously, I will need plenty of support from you all to accomplish this. That way, I can pass this knowledge along to my children and hopefully keep the Buick hobby alive. Also, I want this engine to really pop when you open the hood. I want it to look like a piece of art. I have a lot of ideas that I will need to sketch out. Some of you will love it and some of you might get mad with me. While I do plan on keeping things original, the only thing that I want to modernize is the color scheme. It's going to be an interesting journey, but I hope you all can enjoy it with me. 1 2 Link to comment Share on other sites More sharing options...

EmTee Posted November 24, 2019 Share Posted November 24, 2019 Be sure to read @KAD36's stories from the original rebuild as well as the 'Take-2' follow-up below. My takeaway is that even if proper procedures and techniques are followed, parts availability can be challenging and selecting the wrong parts, or even reusing what appear to be serviceable used parts can have significant consequences regarding the ultimate success of the rebuild. I applaud your objective, but just want you to understand that the research involved, even when building on the experience of those on this forum, will require a significant dedication of your time. https://forums.aaca.org/topic/334282-1955-322-rebuild-take-2/?tab=comments#comment-1939592 Link to comment Share on other sites More sharing options...

You worry too much.... Ken built a good engine and a nut on a rod cap shattered (never heard of before); he came up with a fix. Myself, even after his experience, I would just re-use parts like I did on all the nailheads I had a hand in building. The problems I have had is with machine shops: you need to double check their work! And I can tell you where to check. 1 Link to comment Share on other sites More sharing options...

KAD had a heck of a time finding pistons for 'take-2' (as you're well aware) and the camshaft used for the original rebuild seemed to be a compromise (like the pistons used for the original rebuild).

I found with my poorly rebuilt 54 264 the cam, lifters and push rods are new and for a 56. If the geometry is right she'll run. Can't mix years. I reused the cam, rods but replaced the lifters. Cam was not wiped after starting for the first run in. Reused the .30 pistons. I was either blessed with a happy running rebuild or I RTM and took the advice from those that have rebuilt them. I'm saying it is a bit of both. Edited November 24, 2019 by avgwarhawk (see edit history) 1 Link to comment Share on other sites More sharing options...

Sean Batiz Posted November 25, 2019 Share Posted November 25, 2019 I realize that your plenty far away from needing this little piece of advice but, when the time comes to mount the exhaust manifolds, DO NOT USE ANY GASKETS‼️ These Nailhead’s don’t like’em! If memory serves me correctly, they don’t allow heat to correctly dissipate and can cause exhaust valve failure. Link to comment Share on other sites More sharing options...

RivNut Posted November 26, 2019 Share Posted November 26, 2019 Yep, no gaskets from the factory. The exhaust manifolds act as a heat sink pulling heat from the head and letting it flow out through the exhaust pipes. Much less work for the coolant and the radiator. 3 Link to comment Share on other sites More sharing options...
Kosage Chavis Posted November 26, 2019 Author Share Posted November 26, 2019 Over the weekend, I finished removing the rest of the external parts from the engine. First, I removed the oil filter assembly as shown.Remove canister retaining bolt shown here.Catch any oil with an oil pan. Remove. Then, remove the 4 bolts shown here.Again, be ready for oil to spill when flange is separated. Remove. Showing the site of removal.Showing the oil filter assembly removed from engine. Next, I removed the engine dipstick as shown.No explanation needed here. Showing removal site.Showing engine dipstick removed from the engine. Next, I removed the distributor assembly as shown.Simply remove this bolt with the hold down arm as shown.Wiggle/turn the head of the distributor until you are able to slide from bore. Remove. Showing site of removal.Showing the distributor assembly removed from engine. Finally, I removed the starter motor as shown.The starter is held in place with 2 bolts. 1 at the top and 1 at the bottom that is more tucked away.Remove the bottom bolt first. Then loosen the top bolt just a bit. Support the other end of the starter with your hand and then remove top bolt completely. Slide the starter out and remove. Showing site of removal.Showing the starter motor removed from the engine. Overall, all tasks in this post were easy. Now that all if the external items are removed from the engine, it's time to seperate the transmission from the engine and finally get the engine on an engine stand...hopefully this weekend.

Oh, that's just lithium grease that I sprayed the cylinder walls down with to prevent rusting. Maybe I can wipe it down and take a closer photo. From what I could tell, there were no honing marks. There is a decent lip at the top of some of the bores also, if that gives you any clue.

Sean Batiz Posted November 28, 2019 Share Posted November 28, 2019 Had I chosen to break down the engine in my first Nailhead to have thoroughly removed all of its “dried up sludge”, BEFORE attempting to continue running it (regardless of having fresh oil), it most likely would still be a runner to this day, instead of having its #8 piston completely disintegrate into a pile of aluminum shrapnel at the bottom of the oil pan! 1 Link to comment Share on other sites More sharing options...
Kosage Chavis Posted November 29, 2019 Author Share Posted November 29, 2019 My Dad got me a welding machine for my birthday. I have always wanted to learn how to weld. My Dad has been welding for decades and is a master welder himself. If I can be half the welder my Dad is, then I will be able to do the metal repairs on the Buick. Can't wait to start learning! 5 Link to comment Share on other sites More sharing options...
Sean Batiz Posted November 29, 2019 Share Posted November 29, 2019 No offense to you or your dad but, unless he “still” has great/decent eyesight, seek your welding knowledge from multiple sources! Anyone whom has performed good welding procedures for many years and still possess decent eyesight, generally can be trusted to know what they’re talking about; those whom are lazy about these skill sets, mainly with regard to personal safety, will usually have pretty bad eyesight before even 45 years of age. PROTECT YOUR EYES AT ALL COSTS ‼️ Just my 2¢ on the subject of welding, based on my own experiences with what welding skills I’ve personally learned over the years. In other words, spending what might seem like too much on the necessary helmet/goggle lens arrangement, will be less than having permanent or long term sight loss. This all said, GOOD LUCK & ENJOY! Welding can be sort of therapeutic or meditative. 1 Link to comment Share on other sites More sharing options...

Not worried about that with my Dad. He knows the different weld processes, know how to weld different metals of various thicknesses. Oh, and he has decent eye sight.

Sean, how much did you run that engine before it became ruined? Link to comment Share on other sites More sharing options...
Sean Batiz Posted December 6, 2019 Share Posted December 6, 2019 Three years of intermittent driving. It wasn’t a daily driver by any stretch of the imagination but, I did really enjoy driving it around from time to time. Purred, drove, ran, flawlessly & superbly quiet! What really made matters worse for its ability for proper oil flow, was when I was running it in below freezing temperatures (actually had a pretty harsh winter here in So Cal back in 2005); the sludge and grime severely reduced the ability for the oil to enter the oil pumps’ pickup tube screen. If I were to guess, I’d say that I was only able to enjoy about 1,500 total miles out of it over the 3 years of owning it, up to that point in time (I bought it in Nov. of ‘02). Not sure how to estimate the total hours of operation. I really didn’t think that it’s oil pan had as much buildup of caked in layers of rock hard sludge/grime, to the extent that it very much did indeed have. Once I broke everything down, I discovered that the oil pan had roughly a 3” to 5” thick SOLID layer of thick sludge and grime buildup that near completely encapsulated the oil pumps screen. I had to literally chisel the hardest layers out of its pan & honestly, couldn't believe that it had as good an oil pressure as it did. Lesson learned, the hard way! On a sad, creepy note, these “ La Brea Tar Pits” of ancient engine oil, was comprised of several interlaced layers of small rodent skeleton cakes, apparently from various wild critters having climbed into the hole in the valley pan where the road draft tube mounts into; it wasn’t fastened into position for what looked like, MANY YEARS. When I first changed its oil, I went through 3 changes within the first 500 miles to flush it but, that method apparently doesn’t do squat for hardened grime. 1 Link to comment Share on other sites More sharing options...

No way to get in that location. Someone left the distributor out or the oil fill off. The pan on all old engines should be removed for cleaning before running! Inferior oils from the past along with lead in the fuel formed that sludge. And that lead laced sludge is highly toxic: use gloves and put into old paint cans for proper disposal. 2 1 Link to comment Share on other sites More sharing options...
Kosage Chavis Posted December 6, 2019 Author Share Posted December 6, 2019 Building a rolling carrier for the dynaflow transmission.

Sean Batiz Posted December 7, 2019 Share Posted December 7, 2019 After really digging through the dust in my memory, I “think” that the oil fill cap was in the trunk when I first got it; earlier 55 only had one cap for neck at the front of valley pan, none on valve covers. It’s distributor was definitely in place but, why I was suspecting these critters went in via the road-draft tube as well, had to do with my car having been one of the many older models of cars in the mid 70’s that went through California’s smog check program which called for it’s road-draft tube to be literally chopped off about an inch out of its port for a rubber elbow to be attached (rotted away and hole exposed) that was routed to the top of the oil bath air silencer/cleaner housing that also received a roughly chopped hole in it for this rubber hose/elbow arrangement to fit (this tube extended through the housings top and was fixed to another hole cut into the filter element itself to the clean side of the element; a fruitless attempt at creating a closed crankcase breather system). Either way, I just remember having fished out MANY tiny bones along with that ‘leaded’ sludge! Yes, you are correct in that one “should” clean out the oil pan in an older engine BEFORE running it; as I stated, Lesson Learned the Hard Way. I most definitely did place that nasty stuff in a proper pail for disposal; really stunk badly too! According to its paperwork at the time that I bought it in ‘01, it was last registered in 1976 so, it definitely sat for awhile. Kosage, your transmission stand is looking great & it oughta hold up quite well, for what you intend to be using it for! 1 Link to comment Share on other sites More sharing options...
