Freelander 1 Compression test on K series

Hi guys, asking a precaution question here.
So I do have this cheap compression test.

My concern is how do I screw these in (attached, in blue) since it's way too deep and after the test it might even tighten more, I cannot put a socket in there or fingers.

Am I missing something? did somebody use this before and can share knoweldge?

Thanks,
Paul

I found some safer kit, https://www.ebay.co.uk/itm/162449242623
Says 14 or 18mm spark plugs, the socket is 16mm but no idea how much the thread is, any ideas please?

Does that piece screw on the hose end?

looks to me like you need to use the long straight bit in the gauge direct and just hold it in place.

A guess never used one.

Thanks, I have found outube videos from other people.
A flat screwdriver will work putting in the middle, even if it damages the middle a bit won't matter.
So I have solutions, compression test tomorrow.

I use a long reach adapter, like this. https://www.machinemart.co.uk/p/clarke-cht748-long-reach-compression-tester-ad/

Thank you, good catch. Not very abailable around but I will manage to find it.

As I understand it, the screw on adapters are for different threads of spark plug, the idea being you screw the adapter that matches your spark plug threads onto the hose, screw the hose into the sparkplug port in the head then snap on the quick disconnect from the hose to the gauge. But on twin cam engines where the sparkplug is down a deep well, it can be a pain if the adapter unscrews from the hose rather than from the head. Typically the larger threads are for spark plugs, and the smaller threads are for glow plug ports on a diesel.

My google-fu was strong today so I fond this instructions manual for you:

yes I have those as well but does not say what to do in this case since I cannot fit any socket install or remove.
I guess it's to figure out myself.
Found a long one in Bella Italia will have to order.

The trick is to screw the thread adapter onto the extension very tightly. However when screwing the whole assembly into the plug hole, the thing only needs a gentle nip up with your fingers. There's an O ring on the thread adapter, which does the sealing, so it's not necessary to be super tight. As long as the screw fit in the plug hole is less tight that the adapter to the extension, the whole assembly will come out as one.

I've been using these things for years, and not had a thread adapter come off the extension yet.

I know what you mean, and what you've described is what I do, but I was deliberately being vague to let the OP have reason to think about the potential mishap, thinking if they thought about the risk and came up with a solution, they'd be more likely to remember it than they would be if they tried to memorise the steps in a post someone on here posted.
