Re: Engine rebuild

I'm waiting forever locally for Machine Shop services. I found a motorcycle shop to do cylinders with plates I have on loan but it's expensive. I don't trust sizing on off the shelf cylinders. I've been unable to find another person to do heads. No one wants to invest in tooling for flycutting head ...

Re: EM - Axle rubbing on A-Arm opening

Sitting here I would imagine positive camber would make the axle move towards the bottom of the A-arm hole and negative camber would move it towards the top of the A-arm hole. I also imagine that the height of the powertrain would have more of an affect on where the axle is located in the hole than ...

Re: Puzzled by Leak down test results and next steps

I don't know what happened but it seems like we used to change spark plugs first thing. Maybe it's because the new cars can go so long or maybe it's because they're 5 bucks apiece for regular plugs these days.

Re: WTB Six NOS LM STD Barrels

If I bump it out to .004 or so (.002 on each side) with forged pistons I don't notice any piston slap either.
On a somewhat related related note, I sure take apart a lot of engines that have the piston arrow pointing to the harmonic balancer and not to the front of the engine.

Re: Changing Transmission Mounts

It's been a while but I don't think it will be too bad. If memory serves, it's easier to get to the top of the bolts on a LM than on a EM. At least these days you don't have to worry about core value if cutting the nuts off. If your 66 is a Manual I'd disconnect the shifter yoke at the transmission ...

Re: No more Bando 3V560 fan belts???

A while back I looked for Dayco top cog belts and couldn't find them anymore either. They're 10mm so a little wider than 3/8. One fellow bought what was supposed to be a top cog but it arrived with inner cogs which I don't care for. I bought a batch of Gates 3V560 on Ebay a while back to last for a ...

Re: Corvair Preservation Proclamation

It will certainly be interesting to see how this all pans out. Formal declaration or hostile takeover are some heady terms. I'm awaiting election returns with bated breath. I haven't seen much for polls or projections. Discussion of a donation to CPF by Corvair Minnesota fell flat because it seems t...

Re: WTB Six NOS LM STD Barrels

I would not think of Clarks full fin cylinders as "thicker barrels". The fins go all the way around the studs so they're more stable. That's how VW cylinders are. I believe it's a classic case of GM doing it right to begin with and then doing it cheaper. The problem with using '60 3 3/8 cy...

Re: New to ALL THIS! just got this 62 Corvair Monza 900

bbodie52 is absolutely correct that the duct on the right front of the top shroud needs a hose or the opening blocked off with a plate made by tracing the duct onto a piece of sheet metal. If you have a big hole there for the cooling air to escape the engine will suffer in a big way. I can't tell if...

Re: Puzzled by Leak down test results and next steps

I would not expect the carburetor tuning to change much with the new spark plugs but it wouldn't hurt to fiddle with them if you'd like. I like to write down changes in case I want to go back and forgot where I was. I wasn't thinking the #2 lifter adjustment would be related to the smoke, I was thin...

Re: Oil Pressure Issue at startup

Sorry to hear about your injury and hope you have a good and speedy recovery.
Any news on the old Suburban, was it like a '37 or something?
I saw your old blue '64 Greenbrier the other day, it's doing good.

Re: New to ALL THIS! just got this 62 Corvair Monza 900

If the pushrod tube o-rings are leaking they drip oil onto the hot exhaust manifolds and you get smoke out of the rear ducts especially. It won't smoke when you first start the car since the exhaust is not up to temperature. If you're getting smoke out of the exhaust pipe that may be a little more s...

Re: Puzzled by Leak down test results and next steps

I've avoided saying anything because I'm not sure I have much to add. Your Compression Test numbers seem pretty good. Your Leakdown Test results are not so bad. It's not terribly unusual to hear a little air in the Intake, Exhaust and Crankcase. Some folks will say the platinum plugs don't work well...

Re: Engine Rebuilders

I've been doing it in Minnesota but I'm trying to ease up and fade away. I'm assembling engines from good parts I've collected and selling them off. It's like "build it and they will come" when it comes to buyers. I've got a few now on a take it or leave it basis when done. It's getting ha...
