Got one of the compression testers Kram linked to above, decent enough for £13. I’ve got a stihl kombi motor that runs okay - ish but I think it could do with a bit of tlc

Hi, Im sorry to say my test results are not great, it appears to read around 50psi lower than my other one and often more with a lot of inconsistancy, I
dont think these can be trusted. My comparison is against the Husqvarna recommended one here

Compression Tester - Genuine Husqvarna Part - 531 03 16-86

Compression Tester for Husqvarna Machines Genuine Husqvarna Part. OEM No. 531 03 16-86

I did buy it primarily for the 10mm thread adaptor, as I have the Husqvarna one.
Its a shame as in some ways the quick release gauge makes it easier to use - but the small knurled head does not!

I suspect the hose is leaking at the crimp as it rotates easily, or the 14mm thread/oring as it appears the oring is getting squashed out. More testing needed. I may be sending it back.

I’ll see if I can get mine tested this weekend but as I have nothing to go against not sure how it will look. If nothing else I can use it as a comparison between 2 I guess - I’ve got a kombi motor and a leaf blower to try

A fuel tank back in the 6x6

Decided to stop fannying about and cut all the stupid fillers off the top of it, plated them up and then cut an even bigger hole for the EFI pump and sender unit donated from another vehicle. Even slapped some paint on it!

Now to finish all the wiring, apply some "modifications" to the exhaust manifolds and sort out some plumbing for the power steering, cooling and fuel. Then see if my custom ECU fires it up.

I got some Meccano yesterday.
The middle tray was jammed.
But I git it free.

This was jamming it.

 

[Cobbler]

That looks like the Meccano clockwork motor that I had about 60 something years ago.

That is because it is.

Have you got a vehicle specific wiring kit with it?

 

[nickk]

No.

 

[JOEPRO]

No.

I presume this is for a modern car with can bus lights? If so you are better to use a vehicle specific kit for many reasons. And failing that the next choice is a generic one fits all canbus module but be ready for pain IMO. Proper kits aftermarket for Mercedes at least are about £150 and work great. Have to splice into 2no wires only (can bus) and they work perfectly + talk to the cars parking sensors etc properly

A spray of silicon grease on the adaptor union thread & O ring seal and seat might see you get better readings .
As the " O " ring will tend to deform & leak if the seat is not perfectly parallel to the plug base so a bit of lube might just be the correct solution to get a decent seal . I'd also treat the pressure release button seal the same as I've know them to be leaky too.

Adaptor to air compressor? if you have one with an acurate regulator gauge.
