Little JB-weld and some duct tape and that cylinder will be just fine! :tu:

Re: Weekend Work 140 Motor Progress

Hello Everything and Everyone Corvairs! This past weekend I made some good forward movements regarding my 140 engine rebuild; finally got the blower housing installed with a new bearing (thanks for all the advice!), awaiting alternator delivery this week, and got the trans-axle up on my sturdy rolling worktable by watching Andy do it by himself! He's pretty strong. As hard as it is to believe, the bolted pressure plate, clutch disk, and throw-out bearing pulled out of the this mess-are going back inside. My friend Andy was holding and turning the throw-out bearing in hand cautiously stating, "I'm not going to tell you to use this old thing...and then added, hey this feels really good!" I need to back off and reorganize my increasingly messy work area and round-up my assorted car parts. The entire Corsa heap was full of loose parts when it arrived. Some of them have been for a 1964 Corvair. I also need to study up on what the heck I am doing. It's not for everyone you know, you have to want it badly! And, I want to run this car. BTW-The wonderfully written and photoed Vintage Motorsports Magazine has a one page on BS Levy (great automotive writer) driving jay Leno's Stage II Stinger, says it goes like a bigger, somewhat cruder, 911 Porsche. Grundy's Insurance also has an ad with a Stinger, American Porsche! Updates will follow in a week or so. Compression checking is on deck soon. :chevy: :tu:

I realize now what my worktable is missing - THE BOTTLE OPENER!

You may have already mentioned this, but did you end up splitting the case open? Also, did any of your studs come out when removing the heads?

Hi Joe Farmer, yes, I split the case and yes, two studs pulled out. It was fairly easy to remove the errant studs and get them back in place with vise grips. I put the case back together clean and dry, no sealers. Get the cam timing right, it's your only chance! The bottle opener was donated by another friend and is a nice accessory indeed. My Corvair rebuild threads got a little wayward because, I'm a online novice. Crank and camshaft checked good! I opted to go with the 1965 only camshaft, it was in great shape or a regrind, not sure.

Hello! I keep moving forward and wanted to share! There sure are a ton of screws, bolts, and nuts involved in a Corvair engine and cover; found most of them. I managed to sort out some more boxes of car parts too. Next I'm going to get the trans-axle tightened up. It's ticking down like a time-bomb to oiling and compression checks. D-Evolution Corvair. My first Corvair engine rebuild. In my own cave-of-man garage.

Picking up my rebuilt rear wheel bearings assemblies soon too, from a Corvair demigod in the Mojave desert at the end of this month. :not worthy:

Hi - is there any truth in the recommendation of replacing your camshaft if you are replacing your lifters during a rebuild?

Hi Going4joe, I think that question boils down to the condition of your current worn lifters and camshaft. Some guys are always replacing EVERYTHING all the time! I can't and don't want to do that. If your camshaft is in good shape, I'd run it with new lifters. But, I'm sure that there are a lot of different opinions. Every engine repair, or rebuild is different, especially when you're talking about 50 or more year old cars, and they all have their own histories.

You should have put a little sealer between the case half's in the red circled area's in this picture, these are the only area of the case's exposed and might develop a leak if not sealed.

Camshafts and lifters when installed new wear in to each other creating wear patterns on both that hopefully the cam and the lifter are happy with. When you put a new lifter against a used camshaft that wear in happens again and the result may or may not be happy. Worst case it can cause cam lobe failure. The possibility of failure from this is a smaller percentage perhaps a very small percentage even. My rule of thumb is that if the lifters seem to be functioning well before rebuild and the cam and lifter wear surfaces look ok then re-installing the old cam with the old lifters may be an option. NOTE each lifter should be put back in the same spot it came from so that each cam lobe is contacting the same lifter as before disassembly. To not do this asks for trouble as cam failure would be even more likely than placing a new unworn lifter on a worn cam surface. I would certainly not put a full set of new lifters against a used camshaft during re-build, just asking for trouble in my opinion. I would certainly not put used lifters against a new cam.....lifters are pretty cheap. I have replaced failed lifters on a one by one basis on used cams a number of times and have never had one fail on me yet, but, the possibility is there, and I know other people that have had cam failures after lifter replacement (of course perhaps the cam was already failing?). When I rebuild I generally replace both cam and lifters with new parts, it simply takes too much work to go back in and fix problems here.
