Which 1.9 timing belt NA

[bpcaddy]

I feel bad cause I never contribute to this forumn....even though I maybe shouldn't pass on my so-so posisblly wrong knowledge lol

How do I know what 1.9 I have?. Really frustrating. I've looked for the stamp on the front and it's rubbed off. 

In an mk1 caddy I think it has original engine mounts

know it has original 1.6L bosch ip pump, air box, fuel filter, oil filter, rear tranny mount, cv axles, fuel cable, clutch cable, glow plugs.

Which timing belt is it?

Also. Stripped a glow plug a little bit. Plan is to take ip off and put in an expandable back tap and go in and out 10 times slowly increasing the diameter.

if its an idi pump and you are sure its a 1.9l you want a timing belt for a AAZ. Tell the parts guy, or look online for a 95 jetta 1.9l turbo diesel from canada. post a picture of the engine and we can help identify it. The AAZ has 3 bolts in the middle of the valve cover holding it down, the 1.6l has like 6 or so on each side. Also the AAZ PCV () valve on the valve cover will vent back into the side of the block, the 1.6l just feeds it back into the intake I believe. If you can get a good look at the back (left side when facing the timing belt) of the engine it should have 1.9l or 1.6l stamped on the block.

I'd spray that broken plug with penetrating oil multiple times over the course of a couple days before attempting to get it out with a reverse tap. Use all the help you can get to avoid screwing up the threads in the head.

why do you want to expand hole&thread diameter? new metal? more (new)threads? why not try a standard tap first and then try and see if threads now will hold.

Because it's going in crooked further 30% and stops.

I don't want to get a bad path going. Expandable let's me follow the threads at the very back and at very least cut through the stripped threads maybe.

Running_wild. Plug is out. When I go to put it in it goes crooked and probably stops because of the sidewall of the hole or I just don't want to press it more.

expandable back tap and go in and out 10 times slowly increasing the diameter.

my experience is running a tap(or die) once, correctly tho, giving the chance to cut the threads, but doesnt seem necessary or beneficial to run it multiple times, &also increasing diameter, if your increasing diameter of hole/threads, if you get threads right then run a std tap down it, you should be ok. std tap is extra and may not be necessary.

Thanks. May do it one time if I get it lined up at the rear

so i figure what your saying; so you have an expandable back tap; it sounds like its a jimmy-jack-hope-you-want-it-to-work gizmo typie, hey, well and cool, keep-your-fingers-crossed. so its a good idea, as i know what your getting at, use the good threads, and run 'new' threads. so expand tap, get the 'new'set of threads, take a standard tap and run down(no im not saying quickly, or carelessly). 3 times to run a tap is alot. the threads you make are not going to be as strong as the original, so dont strip again.
added: dont forget to lube tap
added: i like a good tap, i dont like to skimp.

YouTube of the tool I'm talking about. Looks like a sweet tool, if I get it I'll post how it works. So yeah different than you guys have probably used. Plug onlywent in 30% so I'm guessing it would work.

The hole is not "stripped" it is cross threaded. Slick tool for bailing out dummies. I hope you are not the one who cross threaded a GP.

Slick tool for bailing out dummies.

tool isnt the correct term for 'item' he's using, 'jerry-rigging' is to put it mildly. i wont say the other term,,heheh.

so its a good idea, as i know what your getting at, use the good threads, and run 'new' threads.

and to clarify above, idea *may 'seem' good, i suppose do the best you can.

[bpcaddy]

Yeah. Jerry rigging correct. Got tool and it needed to be modified. Could have worked but I just used a tap and cleaned it up a bit. What a mess. Waiting till tomorrow to time the Injection pump.
