Thread: Chevette blues

Tweet

I would love to see pics of your "Vette" . I love the oddball stuff! I even joined a Facebook group called Undesired Survivors.

Thanks for the feedback, as usual I poorly worded my question.

I know how to set the timing. As the guy in the video says, it's pretty easy. My question was, (not this specific engine) is there a way to confirm the cam timing without actually tearing things apart and visually inspecting timing marks.

It seems that this is one of those diagnostic steps which doesn't have a shortcut.

Thanks

This is the cheapest I've seen. Bolt it to the front on the crank and turn the motor while reading the wheel.
this is the best shortcut I know of. and it can work for each cylinder..

To get accurate info wouldn't you really want the head(s) off to get true TDC and zero your degree wheel, and then to work off of lifters on the cam? I guess pulling the valve cover and working at a rocker arm is good for the cam measurements, and there are other reliable ways to find exact TDC, like the water tube method, so a guy could zero his wheel and verify/set cam timing without tearing things apart if his cam gear has provisions for adjustment. Just thinking this is most often done when installing a cam, to double check it against the cam data sheet.

It'sa Chevette! Get the marks lined up and call it good imho.. But, the guy wants some info on the cheap and it isn't like he can even gain a lot of horse power, but he wants whatever it can give. I get it. Yes, there are many ways to skin this cat, and even if you find an error, what'cha gonna do, custom grind an offset key? I doubt any/many speed parts existed and I ain't looking up a cam for a Chevette! LOL..

Seems to me that 'bird is asking a more general question, not specific to the challenged on many fronts Chevette - can you verify cam timing (on an engine not specified) without disassembly?"

Sorry if I'm wrong on the question.... Assuming I understand the question, I believe the answer is yes, with a few hoops to jump through to confirm true TDC.
