Looks like a piston problem to me.

[Under Pressure]

That looks like more work. Turn the radio up louder.

Melted to ring view - not good!!!!! Who's ring are we viewing?

[dagenham]

I rebuilt a 2.3 years ago that looked like that. I had to have it bored .040 over to get it cleaned up. It ran while it looked like that too. Any bug in the vicinity of the car didnt stand a chance though.

I was referring to what you were looking at not what you were looking at it with.

There are still a few of us old died in the wool Mac relics hanging around. Imagine this, a few of us even drive old boosted Ford relics.

I was referring to what you were looking at not what you were looking at it with. Indeed!!

The gent whose engine made this pic, noticed that his car (engine?) was running like crap after a few track sessions (it was also overheating). So he pulled the spark plugs and noticed that #4 had some of the ceramic cone damaged and parts of it were missing. He replaces the plugs and continues to track more. Same thing happens again - broken spark plug ceramic cone. Replaced plugs again and tracked a couple more sessions.

After scoping the engine later, he decides that the spark plugs came apart and damaged his piston! In reality it was exactly the other way around -the piston fractured due to excessive, continuous detonation and the piston parts flew around inside the chambers, damaging piston tops and spark plugs. Also note how literally melted the edges of the piston are where the pieces are missing from. I have tried to explain to folks that spark plugs don't just normally break - something has to hit them or there is SEVERE detonation.

I've also seen pics of spark plug gaps completely closed and folks think that happened purely from detonation. I tell them to go look for the missing pieces of their piston to be hammered into the head somewhere. I've never seen detonation close a plug gap - only some impact with loose parts in the chamber.


There are still a few of us old died in the wool Mac relics hanging around. Imagine this, a few of us even drive old boosted Ford relics. I have several hundred MAC computers/users at the office. A few hundred Win users and about 3000 assorted *NIX boxes, some with users. We're working on rolling all of them into using Active Directory authentication / login.

The joys!

Ordered one! :cool: Looks to be handy to look around in all of the nook and crannies of an engine compartment. I was standing on my head trying to read a part number on the bottom of an EGR valve so this may help.

Thanks for the lead.

Just think of all the money you will save your friends on Colonoscopies !

[MikeFleming]

Is this a problem??

Looks like someone got a borescope stuck while it was spinning. :stick_poke:

[MikeFleming]

Note the melted parts of the tips and the thermal/mechanical cracks in what's left. The appearance of FOD damage is from the balde tips coming off as they melted and impacted the following high-speed blades..

Are you saying melting is the intital cause of damage? Looks more like FUP damage. :p

Got my scope today and it's cool. :cool: Pictures aren't as exciting as yours, yet, but found it can get into real tight spaces where a camera can't. The only drawback is if you are in a tight area and need to see something at 90 degrees, the camera body is a bit long. Certainly can't complain for the price.

Thanks for the lead, I'm sure it will come in handy more than once! :like3:


Pictures are from tight, obstructed areas,

I'm waiting for an RMA. So far, 3 out of 4 that I rec'd are bad. Bad cable end at USB connection, bad/intermittent connection at camera lens, and one is completely dead.

[rodster]

Well that sucks. Is the seller being cooperative?

[Patrick]

Not really. 7 or 8 Emails later, and they insist that I Email them a video of the problem. My Email won't allow a 100 meg video attachment, so I sent them a couple videos loaded on to Youtube. They say they can not see the videos. The automated responses would be comical if I weren't hung out to dry awaiting a RMA for the bad items.

I purchased one from Harbor Freight...


Like everything from HF, it'll eventually become a hammer.
