maybe your hydro lifters are starting to tick, just like every other VW with hydro lifters..

does it just make noise for a few seconds, then go away?

ROR has already diagnosed it:  starter slow to kick back out (take it apart and clean it) and worn, crudded up or otherwise lazy lifters.

The starter will get worse in cold weather. Better to deal with it now.
The mask and the shot(s) are actually an IQ test. If you are wearing or circulating, you just failed the test. I can't feel sorry for you.

My 88 1.6TD has a good tick going on, but I am not overly worried about it. It is definitely coming from the engine, but alas if she pops.. Its getting a M-TDI and a Rover pump ;).

What weight oil are you using? I thought this noise was a few seconds after start only? Nearly every hydro vw 4 cyl I have ever worked on will clack the lifters around for a few seconds at start-up based on temperature and weight of oil used.

I have 15w40 conventional in the 88, 5w50 full synthetic in the 84 AAZ, and 0w40 full synthetic in the AHU M-TDI. Out of all of them the AHU has the most km's by about a 125,000 difference on the AAZ.. and it has no lifter ticking. Must have upgraded the design by the time they got to their third diesel engine generation.

had a feeeling it was the solenoid...

my GTI does the same thing..

solenoid is getting lazy, and probably the bushing getting worn..

Ya, my solution to hyd. lifter problems is simply not to rebuild any more hyd. engines. Life is so much better in their absense. I love my newly rebuilt gas digifant block mated to an older GTI Rabbit head. Plus, it runs like a molested chimp.

It has a tick when running. But it also has this squeaky duck quack noise for one second at start up(which i thought might be lifters) but now think it is something starter related now that i think more about where the sound is coming from and that you guys mentioned it. Otherwise the sucker runs like a champ. Ip has an air leak somewhere in it but only enough for the backflow on the in flow to get a air bubble in it once i shut it down and it isn't pumping a sporadic burst of bubbles in the out flow. When i get the fuel pump installed it wont be any issue. AND when i get myself a resealed td pump ;D

tick when running is lifters..

wait till its about time to change oil, and add 1qt of ATF or MMO in the oil, run it for a week, usually cleanes up the sticky lifter..

oh, definitely, if it sat dry..

have you rally had this engine up to operating temp for more than a few minutes yet?

my Audi GT clattered like no other when i fired it up after sitting, and i thought it had bad lifters..

after i drove it for a week, they got ALOT quieter...

a quart of ATF and another week, and the lifters were SILENT..
