Re: Balance Tube Fittings 140 - Change?

Brad, Thanks - I got that setup. What I didn't realize till I saw your pictures was that there is supposed to be a clamp holding the crankcase breather tube and the PVC tube together. I don't have that (I'll need to contact Corvair Ranch). Also there are 2 air connectors on the turbo air cleaner. Th...

Re: Balance Tube Fittings 140 - Change?

Since this topic turned a PVC discussion, I have a question. My Corsa turbo does not have a complex PVC arrangement. A rubber tube from the crankcase cover runs into a nozzle on the air cleaner. Is that the stock arrangement for a 65 Corsa Turbo ? There is no PVC valve anywhere in the path...

Lifter questions...

I've spent the last couple of days installing the heads on my Corsa engine. I installed all new lifters since I installed a new cam. 1. Once I got the rockers adjusted, I checked the rocker-to-lifter range of motion by rotating the rocker so that the pushrod is depressed into the lifter cylinder. 11...

Re: Oil Slinger...

I do have the Shop manual AND the Assembly manual. As I said I couldn't find any reference to a washer. The washer was on the crank however - in front of the slinger I believe. Since there is no key way in it, I had to remove the key to get the slinger off the crank. I'm just trying to find out if i...

Re: Cam timing - what to trust ?

If it is an aftermarket cam I would check it with a degree wheel. My custom grind Crower was 16 degrees because they cut the key way slot in the wrong spot! Dave has had similar experiences. I have an OTTO-20 cam and I did degree it. Except for the intake close setting it was pretty much on the mon...

Re: Pilot Bushing

Hah I've done that, but I used bread instead of grease. I saw a number of discussions on the net about using bread to remove a pilot bushing. I decided to give it a try - what could it hurt ??? My first problem was I didn't have a rod which fit the inside of the bushing. I tried a 1/2" rod, but that...

Oil Slinger...

When I dismantled my engine I removed the oil slinger. There was a washer with it. I didn't note where the washer went - in front of the slinger or behind it. All the images I can find on the net don't even mention a washer and none of the Corvair parts companies (Mikes, Clarks, California, ...) tha...

Re: Explain wrist pin offset...

I'm really looking for the answers to 3 questions:

How much offset is there ?

Can you measure it with calipers ?

Which side of the piston has the offset (front/flywheel or rear/balancer) ?

Re: Cam timing - what to trust ?

You did not mention what parts are new. I installed a new cam, crank gear, and cam gear. This obviously allows for a number of things to be "off". Ahh, I should have mentioned that. This is a new cam and failsafe cam gear installed by Clark's. I am pretty sure the alignment is correct since moving ...

Re: Cam timing - what to trust ?

I have my crank and cam installed. The keyways line up correctly - cam at 180 degrees and crank at 270 degrees with #1piston @ TDC. However, the timing marks are slightly off. See picture. If I move the cam 1 tooth left or right the timing marks would not even be close. I've seen arguments both way...
