Availability of Injector Type Compression Test Adapter????

[Thomas M]

Does someone make an Injector Type Adapter for compression testing the VW 1.6 non-turbo diesel engine?
My car is a 1991 MK2 with the 1.6 engine. I'm the original owner.

Otherwise, the glow plug type adapter would require the removal of the injection pump.....I think.
I'd like to avoid that if possible.

What size is the injector thread on this engine???

Comments please.

They make compression fittings that work with the injector hole. I bought a chinese kit a few years ago and I searched ebay for "vw diesel compression tester" and find a bunch of them on ebay. The old mechanical style injectors share the same thread size (and possibly injectors) as the old Mercedes diesels. I'd suggest getting a kit that has the fittings to work with multiple engines, so you're set for a long time. You can probably find the same kits as on ebay at Harbor Freight, or similar type stores.

OK. I see the Harbor Freight tester....#93644 is the one I'm looking at.....about $30.

I noticed that the one shown on the HF webpage has "12 pieces" and the one shown on the attached PDF of the 93644 Owner Manual has about 19 pieces shown. I'll have to check this out at Harbor Freight. Model specs seem to have changed. Just wondering if it still fits my mechanical diesel????

You may want to research what's different with the 12 or 19 piece kits. I'd personally spring for the one with more fittings as you never know.
