Is there a TDC indicator mark/drill hole on the GTA flywheel to check against a TDC gauge reading?

Is there not one on the cambelt end on the pulley?

I need one independent of the cams and cam pullies. I know for sure there was a TDC mark on the old 164 flywheels, up to about 1995 at least.
Think we might have got muddled. As in the pulley on the crank at the cam end. Behind the massive aux belt pulley. Basically at the other end I don't know :lol:

Ah yes, I know what you mean. But I was hoping not to have to take the aux pulley off at this stage. Flywheel mark would be more accurate also due to its diameter.

It is often my experience with the internet, that if one asks whether something is possible, most responses will say, "no, it is not", when it often then proves to be entirely possible.

Some of these responses will even suggest that it is somehow inappropriate to even consider such possibilities.

There is no reason why the use of such a mark would be any less accurate it determining TDC than using the dti procedure; indeed, there are a number of reasons why it might be more accurate.

Many Alfa Romeo engines over the years have had TDC marks on their flywheels. My question is simply whether the most recent GTA is one of them.

No need to remove pulley as the mark is on the aux pulley. Gotcha put up a pic of that in your cam shaft mark thread.

I have no idea about marks on the flywheel, always been happy enough with a dti gauge myself.

Indeed he did Mathias, but those links are blocked on my internet.

Could someone please post up that image of the pulley so that it's visible and not just a link.

Thanks to all for the advice. :thumbs:
