Sources for 80-horse rebuild parts
Posted by: FoiledAgain ()

Lifters, main and rod bearings, rings, valves and so forth. Saw some hair-raising prices on main and rod bearings on EBay hence the info request.
This '60 engine has good OP and compression but a fair amount of blow-by so this winter seems a good time to disassemble and evaluate.

Thanks.

A set of main and rod bearings are going to set you back about $170... That is that hair raising? Not sure what hair raising is (not trying to be a smart @$$).

I've scanned Ebay Corvair Rod/Main bearings for years. It seems like the same expensive bearings are never selling. What I found helpful was to know the bearing numbers of the individual manufacturers. Then do a Ebay search on those numbers. Often a seller will get a boatload of parts, not want to be bothered with the application and sell the bearings simply by the part number. So, if you looked under "Corvair Bearings" you would never find them. I found a set of .010 Federal Mogul rod bearings for $60. But honestly in the 3+ years I've been looking that is the best and only decent price I've found and they are not that much cheaper than the Clark's bearings.

BTW, I find "old" car bearings to be all over the map. I have a Rambler American with an ancient inline 6 (OHV). Typically I would find similar bearing prices ($80-$200+) to what you found for Corvairs on Ebay. Yet using the "part number" process I got a set of rod bearings for $9.99 and Mains for $19.99. The irony is some obscure engine bearings sell real cheap..., and others they want a fortune. Probably just two different philosophy's on selling low demand parts. One seller thinks they are rare and another seller wonders if he will ever find a buyer. So, if money IS an issue be patient.

Simple answer is Clark's Corvair Parts.

well, with good oil pressure you may not need main or rod bearings. I would do a leak down test to determine the source of the blowby and proceed from there. You might just need rings and/or some head work.

I think too many Corvair engines are needlessly torn down and then they never get put back together.

just my 22 cents - got my stimulus check y'know grinning smiley

BTW my Turbo engine used .002 bearings from new. Clarks had the Clevitte 77 for a great price. I see there are still some under size at reduced prices if any of those sizes are good for you.

If you're keeping the same cam your original Corvair lifters may be superior to what you typically find these days, usually just Small Block Chevy.
Generally speaking the rod bearings have a tougher go than main bearings so if the crankshaft rod journals look okay you might consider stopping there.
A 60 cam has an easy life comparatively speaking. Not much spring pressure and lobes not very aggressive.
You might consider more of a valve spring.
I too might consider the old "rings and a valve job" with a 80 HP. You can fish the lifters out of the case for a look at the faces but be sure to keep them in their original location.

Thanks, guys. I'm all in favor of fixing what needs fixing as opposed to rebuilding everything. Case in point is the the 40-horse in the '61 Beetle, original to the car, which needed only a hone, rings and exhaust valves, and is over 90,000 miles. The old rod bearings looked fine but replaced them as NOS VW rod shells are quite inexpensive.



Did not feel it necessary to split the case as the OP, never very high in 1200s, was adequate. Runs like a top. Valve clearances are always spot-on.



On the other hand, the Rocket engine in the '55 Olds was ailing, so had the heads rebuilt w/ some porting and while they were at the machinist's checked the bores and despite the 180,000 miles on the engine found essentially zero taper and wear within spec [Olds was famous at the time for high nickel content in their block castings] so honed them and was well into cleaning the original Alcoa pistons, which showed minimal wear on the lands and thrust surfaces- and found 4 of them were cracked. You had to look really close, like magnifying-glass close, to spot the hairline cracks. Very sad. 8 new STD Rocket pistons were not cheap. That motor still runs its original crank bearings and cam. The old rod bearings looked like they'd been installed the week before. Box-stock apart from the heads.



Completely different story with the FE 390 in the '64 Galaxie- everything inside needed replacement apart from the crank. Swear Ford made all its parts from Gruyere cheese in those days. Keeping it stock went right out the window. FE parts are not costly- all things being equal, on a par with NOS VW parts.

So, I'm taking a keep-him-stock tack towards the Corvair engine, which, from what I've soaked up here, is kind of similar to the VW 1200 in that it's small but pretty tough. I'm expecting worn guides and tuckered-out springs and probably seat issues as well. The condition of the lifters will probably factor into whether the case gets split- if the faces are cashed I'd expect the cam is too. I try to read carefully about these motors as I do not have a background in them. I think I know a little bit but old enough to know what I don't know is crucial.

Appreciate the advice w/r/t parts. Not buying anything until I've inspected everything. Definitely a high-level tightwad but if something needs replacement I will buy the best I can, and cry once.

If it runs decent and you have 20+oil press.

Lap the valves, ball hone the cylinders and re- ring with cast iron rings..

Only the 164[64-9] CI pistons have cracking problems.

Note Valstem seals on INTAKES ONLY [ good idea to change while lapping]

You're no novice to engines so you have a good idea of what to expect.

If it hasn't been messed with before you are in luck.

'60 can be bored to 61-3 standard if you need.

Yours likely has the early main bearings still that can cause a soft thump at idle. So that is a reason to change the bearings if they are bad. I think your car is standard though and it less apparent in standard vs. auto.

Tear into it and see what you have. You might get away with rings and seals.

Good luck!
