Title: Timing belt situation
Post by: RJkick on September 06, 2012, 09:35:28 PM

I marked my camshaft gear with a felt tip marker to make sure I put it back on correctly.  I had to take it to the shop where my head was getting repaired and low and behold they cleaned it for me so now the mark is gone.

How do I know where to set it to without the mark?

Any help will be appreciated thanks

If you have a 1992 1.6L 8V when the crank is at TDC for number 1, the cam pulley has a dimple in it that should line up with the notch in the rear timing cover (the one between the belt and the valve cover).
Hope I helped.

I have a 16v but I know of the dimple so TDC and the dimple should work for the 16v as well

Scary since this is the first time doing the head but exhilerating as well

Thanks a bunch

Just remember these were your words not mine!  :P

Actually when the crank is 12:00 & the cam dimple is 12:00 it is at TDC firing #4, not #1 like most engines. Both 1 & 4 will be at TDC, but #1 is on the exhaust stroke in this position. It's also possible the cam cog may have a false keyway... if it has 2, you need to use the "E" slot, not the "I".

Here is a pic I stole off the internet somewhere.  Note where the key/pin is in the end of the cam and how the pulley is positioned.
In the pic, the cam has both sets of valves closed on cylinder #4.  So therefore cylinder #4 should be positioned at TDC (mark on the lower timing belt cog is at 12:00 and lined up with the mark on the oil pump).  With the cam and crank in these positions, the distributor rotor should be pointing at the #4 tower on the distributor cap.

Now Im confused.
If the crank is at TDC for 1 and 4 and the camshaft is positioned as in the photo with the "E" dimple lined up with the notch...
oh right... the OP still needs to know distributor timing because the head had been disassembled, got it.
Thanks for the pic Sky hi, I've added it to my data base.

Yeah I should have added to set the dist at the #4 pole, sorry. That pic is from the former kick-fix site, which sadly is gone, but someone in Brazil put a ghost of it up:

Here's the 16v section:

Also a side note: be sure to position the head gasket top & front properly. It can be installed backwards or upsidedown, but if so it will block the oil feed for the head & destroy your fresh head in short order!
