Re: tdi compression adaptor ?\'s

What's the thread diameter and pitch for the glow plugs? If it is M10x1.0, which I think it is but I'm not positive, then you should be able to use a compression adapter for almost any newer Japanese motorcycle engine.

I bought a kit from NAPA, and it includes a VW adapter. I can't imagine a diesel compression tester that doesn't have a VW adapter! That would be kind of pointless.

Re: tdi compression adaptor ?\'s

i wanted one that was a injector style compression tester that i can try out quickly the glow plugs are a little harder to change fast etc..the nappa one is a tdi injector style one?..mine is a old school larger threaded body looks like a old injector body drilled out with a quick connect on the top etc...any other sources?

Re: tdi compression adaptor ?\'s

UPS arrived as if on command.

Result is: Snap-On blew it. This adaptor is not correct. !@#$

Re: tdi compression adaptor ?\'s

I got mine from www.zelenda.com works perfect. The adapter has an internal valve that traps the compressed air so that you can get a cumulative reading. I think the Original VW/Audi adapter was something like $37.00? I had to get a hydraulic nipple so it can work with my 1000psi compression gage.

I suggest calling Zelenda and just tell them you need the TDI adapter.

Re: tdi compression adaptor ?\'s

thanks drivebiwire..that is the company that i got my 1.9T/ 20v head bolt tool from etc i lost the link since i moved and changed computers. a injector style fitting is much easier to use especailly since you should check to compression when the engine is warm . so removing the injectors is a lot quicker then the glow plugs..thanks

Re: tdi compression adaptor ?\'s

FYI, the TDI uses the glow plug holes to test compression.

Procedure:
-Get engine to operating temp
-DISCONECT THE HARNESS GOING TO THE INJECTION PUMP AND THE FUEL SHUT-OFF SELENOID failure to do this WILL cause the pressure gage to explode!!!!!! (note: you will need to clear the codes when your done)
-remove all four glow plugs
-Hook up a battery charger to keep a uniform charge between cylinders
-Crank until the compression gage stops climbing

Do this on each cylinder, it usually takes about 15 seconds to stabilize the pressure.

What Pete says, except the gauge is not going to blow. I have had one on many a diesel that have sarted and the gauge was fine.

Re: tdi compression adaptor ?\'s

I contacted Snap-On last week with the same question. The phone help didn't know the answer, and sent in the question to their tech group. Said group claims that part # M3576 is the correct glow plug adaptor. I have ordered this and it should arrive either today or Monday. I'll report back whether it is correct or not.

What are some recommended diesel compression gauges for a shade tree mechanic?

Re: tdi compression adaptor ?\'s

argh duh i keep having a vision of glowplugs that are parallel to the deck surface like the idi engine which the glow plugs suck to change when the engine has the pump onit..of course the tdis glow plugs are pointing up. ha

Re: tdi compression adaptor ?\'s

I bought this one from www.tooldesk.com

Hoffman® TU-15P Diesel Compression Tester 1 $38.89 $38.89
Adapter 1 $8.95 $8.95

Subtotal: $47.84
Tax: $0.00
Shipping: $7.95
Grand Total: $55.79

You need to call Hoffman and double check which adapter you need for the TDI I think it is the ATD-5561 adapter. The one I received fits into the glow plug hole. (It doesn't seat on the glow plug seal so I'm not so sure it seals well but it's good enough for the money.)

Re: tdi compression adaptor ?\'s

Yes - I double checked the ATD - 5561 adapter fits my glow plug hole threads. (Note that it doesn't "seal" like the glow plugs do - probably will need to add a washer or plumbers tape to get a really accurate reading.)

Re: tdi compression adaptor ?\'s

Call me crazy but I think the GMC glow plug adapter is the same as the TDI glow plugs, will look tonight. My snap on guage came with the GM adapter (off ebay).

Re: tdi compression adaptor ?\'s

It'd be good to know if the GMC adapter fits.

I've decided that the ATD adapter is NOT good enough for me so I'm going to try (and thats the operative word) to make one from an old glow plug when I get one. The ATD adapter marked the area around the glow plug hole where it seated - I don't like that.
