Can you see ports without tearing down?

Have a shop who did some not so good work. We agreed on what I wanted done when we started last year but seems most was forgotten by the time it happened. Just wondering if there was a way to "SEE" a degree of what was done without tearing it completely down?

Re: Can you see ports without tearing down?

You could use an inspection camera I bet. The kind with a flexible snake with a camera at the end and a monitor.

Re: Can you see ports without tearing down?

I bought one of those cheap 7mm USB inspection cameras off of E bay for about $18 and was happy with it for what I wanted to do. They come in various sizes, so I got the smallest I could find, 7mm. You need to hook the camera to the USB on a laptop, so this could be an issue.

I would remove the carb. The throttle plates would probably cause too much interference to bend down/around into the passages. It also fits into the spark plug hole to see the cylinders. Not bad for $18!

I'd at least remove the carb if you want to go in through the intake side. Harbor Freight has a cheap camera set up, but not as cheap as what gwbutch was talking about. It's also thicker by the looks of it. It's basically a flexible line about the with of a pencil with a camera in the tip. A quick google search will show you all you need.

The HF one doesn't need a laptop, but it's $89. Even with a 20% off coupon it still isn't really cheap.

Re: Can you see ports without tearing down?

What are you hoping to see? Porting job? Valve guides?

Re: Can you see ports without tearing down?

remove the passenger side header/exhaust manifold and take a look in the ports?

probably much easier than pulling an intake manifold. Either way, you won't get a great look without getting right down to the intake and exhaust ports.

OK understood. Many guys back in my day were hogging out ports , making them smoother that a pigs belly which in many cases in the wrong port, hurts.

Not to mention the fact that us older guys never had access to a flow bench much less heard of them. Some of us made port model templates that we found from some Jenkins or Yunick gru. If the template matches , that's what we did, match the contour but we were relying on someone else advice. We did not take in account going to the lightest valve with the largest port seat.
If the die grinder bounced, we had to replace valve seats. The intake sides were always prone to hitting a water jacket.

So unless someone is doing you a favor, I guess you should accept it but otherwise flow bench data sheet is more accurate.

My guess that you have stock heads? I can only guess the best I have seen is intake ports flow about 140/170 at 28" mercury. That's all I know about that.

I saved my self a few buck and lots of effort, I went for a CNC set of AFR 195's. Yep their expensive but you probably get your $$ worth on a set of the newer after market heads.
Really, I am not going to see all that airflow I paid for just cruising to the sonic.

If you don't trust your mechanic, who you gonna trust?

Re: Can you see ports without tearing down?

Most of a good porting job is in the valve bowl.

No way to really see it without removing the valve itself. I use my finger to feel the radius under the valve seat to make sure it's consistent and smooth.
