Topic: Scratch on Intake Valve Guide Bullet End (Read 7389 times)

HDGearHead · « **on:** October 05, 2014, 05:35:13 PM »

Two years ago when the dealer rebuilt my motor under ESP with the T-Man CVO Street Performer Kit, I noticed a scratch on the bullet end of the front intake valve guide. I didn't see it until after the heads and rocker boxes where already installed. When I questioned the builder about it, I was told that it was nothing to worry about, only cosmetic.

I just ran an endoscope/borescope down the throttlebody to have a look and take some pictures of it.

Is this ok or should I pull the heads and ship them to T-MAN to have the guide replaced?

Has that run in the last 2 years?

I know one thing, that is one cool picture.

You can buy digital endoscopes on eBay. A good one is about $30.00, and when connected to your laptop, can take still shots or video and record it.

Thanks. That's what I was hoping to hear. This has been stuck in the back of my head since it was built. I just removed the rocker boxes to replace the comp releases and install rollers and didn't want to put it back together if this was something I needed to be concerned about.

Ain't nothing more than a mark(scratch) that was made with a file to deburr the guide after it was shortened.

Won't hurt a thing.

Around 6K miles. The heads are clean. I found some mild carbon build up on top of the pistons. I assume this is from burning oil from the breathers. Another mod project to tackle this winter....

So tell the truth, you were really just showing off how cool your SnapOn borescope is

They are pretty cool

But this is one of the cheap ones off eBay.

I've got two different el cheapo models.

These pictures were taken with a 8.5mm diameter AGPtek HD 720P 2.0MP USB Endoscope http://www.newegg.com/Product/Product.aspx?Item=9SIA0U01R38863

Its a little clumsy taking pictures since you have to click a button in the app on the laptop to snap it.

I also have a 7mm diameter SuperEyes USB Endoscope http://www.supereyes.cc/en/n013j-7mm-usb-waterproof-digital-endoscope-147.html

It has a button on the wand that allows you to easily take a snapshot. However its picture quality is not as good as the AGPtek.

I really want an articulating borescope with adjustable focus (similar to what we use to inspect turbine engines). Until then these will have to do.

Then you could also pick up some part time work at the local medi center

................right on, and just make sure that the business end of that tool is washed off, in between patients.............

Yeah, I was in an automobile parts store on Friday getting doom parts. They had one for about $125 with built in monitor and I started thinking, which is usually dangerous, that that might be a really cool tool. So while I waited I looked the up online and found some as cheap as $25, but I was somewhat afraid they would not have a very good image. Your images are great! Can you put it in the spark plug hole and see the inside of you heads?

I have the model under this one and paid maybe 90 bucks a few years ago. It still works I have used it countless times. Even on a hot engine which I think there is a caution about that . Super handy tool ..

The real problem with that tool(we have had a Snap-On for many years)is that it makes an insect, look like a rhinoceros........

Scott, it sounds like you got some spare time to go out and bag a buck!

Chris,
Actually VERY busy here, and much more work coming in from everywhere.
My 21 yr old son and I had about 4 hrs in the trees yesterday afternoon.
Plenty-o-deer but I never had any shot presented, as a button buck twin, was being a class-clown distracting this one nice buck, running and bouncing around, my son passed on a couple smaller ones, from a real hot stand we have on the back side of a secluded beaver pond/swamp, but the cameras are telling us to be patient......just a matter of time now.

Need some acorns? We already have picked up two 5 gallon buckets worth.

One of my riding buddies usually comes and gets them - but there has not been one piece of venison that has crossed my threshold - so he will be out of the loop soon

Plenty of beechnuts, apples, soy beans, corn, this years planted alfalfa.
They eat well where we hunt.
