HI, Can anyone tell me where can I buy a Model t compression kit? Thanks
I bought this one the rubber tipped adapters work ok then I bought a set of the 1/2 inch to 14 mm adapters that the vendors sell WA-LA I have a model t compression tester
forgot to add this
I am not sure one is available commercially, however you can make one with no more than a trip to the local ACE hardware and about 18 bucks in your pocket.
Think high end bicycle pump...disassembled and reassembled...1/2" NPT final 'bit'...and miscellaneous pipe bits to make it work.
Folks will grouse that a bicycle gauge is no where near accurate enough...and they fail to realize that even stock compression gauges are probably just as inaccurate! I think the bicycle gauge is probably within 10% accuracy and 'good enough' for a T
It screws in so you don't need a 3rd hand...
forgot to say, in the 2nd one built for my son...the brass pushbutton check valve was part of the bicycle kit I found...I just tossed the hose!
Any decent modern gauge is accurate and adequate for the job. They go higher PSI wise because moderns have higher PSI #'s but as I said their accurate enough in the low range for T use. Screw in type would be a plus, (you'd probably have to adapt something), but a rubber tipped one with a helper works too. Take comp tests dry & wet and write the #'s down.
I use my 200LB compression checker with a 14mm to 1/2 NPT spark plug adapter.
I have similar to what George shows except I put a 12" grease hose inline to make it flexible and easier to get better clearance at the firewall for #4.
I just looked at mine, it's a 300LB not 200Lb. It's an older Sears unit, still works ok at the lower ranges.
OR.... you could drink 4 bottles of wine as suggested in another post, save the corks put one in each spark plug hole and turn the crank 2 times if they all pop out your good to go
GR. A practical suggestion.
I found you must have the gauge with the capture feature. Compression dissipates so fast you will never get a reading above zero otherwise. I bought a 0 to 100 gauge from Grainger. When you are looking at 40 to 50 psi, the 300 psi gauge is too coarse for me.
Now, a question: should you oil the cylinders before testing to seal the rings a bit better, or do it dry, the way the car runs?
Do it dry first, then see how much it improves when adding oil. That is a diagnostic for weak rings. Also make sure the carb butterfly is open.
You can get kits like this one at Harbor Freight or on eBay or Amazon for under $20. Then go to Home Depot or any hardware store for a pipe to screw thread adapter from the plumbing department.

Or make your own adapter from an old spark plug if you have the tools and skills.
