Long title, but if I have the cups out of the head, can I run a bore scope/camera in and see the pistons and cylinders?

Also, with a starter attached, can compression be checked on a motor when it's out of the truck?

I'm looking at a new motor and would like to know as much as I can before it goes in a truck.

 

If you can find a scope with a small enough lens to fit through the hole, yes.

Yes, compression can be done with the engine out as long as you can bolt up the starter.

 

Cups in our out, there is no difference. The injector nozzle hole is about 8 mm IIRC, and so is the GP hole. If you have a scope that small, the easiest way is through the GP hole - if you don't want to gut the heads.

 

A 4mm borescope works great. We use those on jet engines all the time.

 

who makes a good one?

 

This is great to know. I found a deal in a pulled motor with 114k miles. An injector got stuck and flooded the cylinder. It was rebuilt by a ford tech with a new rod and piston in #1 along with new seals and gaskets.

I've seen pics if it, but it's now all buttoned up. A complete drop in motor minus turbo. I'm considering buying it as I've chased my oil loss for over a year and I'm tired of worrying about it.

This will be a motor I can have on stand by should mine give up the ghost. I don't mine pulling the oil pan, but I'd rather not pull the heads if I could scope cylinders easily.

I like my truck but just don't know how it was treated the first 227k miles...

 

There is definitely comfort in having a spare engine in the shop!
