The cam was off by one tooth. I checked the compression before putting the timing cover on and it went from 125 PSI to 155 PSI. After putting it all back together, the truck ran great. Next time I will take the extra 5 minutes to verify the timing.
Racerguy - thanks for all your help and providing the pictures.
I will also thank you for the Info. But I'm still not 100% sure, sorry.
Is your description for both sides?
This would say, that the cam sprocket/tooth with the timing mark from the left and the right cam are always between the Links of the chain.
And the crank sprocket (at 6 o'clock) is for both sides on a bright link?
Just asking, but if I get your description right it seems that the RH camshaft (passanger side) on my 4.6L Windsor is not set correctly - the chain is with the bright link on the cam timing mark tooth and not between???
Would very appreciate if you may got the time to clarify/confirm. I will be tearing it apart this weekend and want be sure that this time everything will be set 100%
Thank you in advance and sorry for the inconvenience it may cause.
Have a nice weekend!!
Just in case that sombody is interested in setting the Camshaft on the 4.6l Windsor Engine
I checked the timing on my 97`Windsor Engine last weekend and the descriptions (Haynes/Chilton’s/Ford Service Manual) I got, are all not 100% compatible.
So I used the “Ford Service Manual” that tells you to fold the Chains in halve and mark the end links (see pic A0041106 in this Thread),
well they showing that one end is a bright Link and on the other side there is a slot – this is definitively wrong.
The Chains having 58 links – 29 links each side, that means you got the bright links on both sides (Crank and Cam) or two slots – depends how you fold them.
I folded the
RH Chain with the bright links on the timing marks and the
LH Chain with the slots on the marks.
After marking the end links - I set the Cams – Crosschecked it with the Haynes/Chilton’s Manual – resold:
LH Cam is exactly at 11 o’clock from the straight surface from the Cylinder head, as on the Haynes/Chilton’s -
RH Cam is one tooth (8,57°) after 12 o’clock, from the straight surface from the Cylinder head
So I got two have right descriptions, trusted the Ford Manual and the Truck is running pretty good.
I’m still not 100% sure. Could be that the Haynes/Chilton Descriptions are correct and the RH Side should be at 12 o’clock, but I will not touch the Engine again just for testing.
catching this old thread because I got a cracked RH Cylinder Head (Cyl.1) now.
I'm still not sure if the RH Head have to be set on 12 o' Clock.
But I can imagine that for the Windsor Engine maybe both descriptons are right.
What I want to say is, if you fold the Chains for the LH Head you can set the bright (or the slot) links to the marks on Cam and Crank - result = 11 o 'clock.
But for the RH you can set a Bright link to the Crank and a Slot to the Cam Mark (this would result that the RH would be at 12 o`clock and not one tooth (8,57°) after 12 o’clock.
Think my problem is, that my chains don't got this copper marked links.
Would be very appreciated if someone can tell me how many marked links are on this chains? Maybe 2 for the LH Side and 3 for the RH (this would make everything clear)?
And what do you think about the 12 o'clock position? 100% right or just a kind of close to be 12 o'clock.
I asked several mechaniks and they all not 100% sure (okay they don't work much on Modular Engines)
Okay Guy's, think I found out how it works!
And on a 1997 Windsor NPI Head 2Valve Engine are only two Marks on the Chains, and this means, that the description from "Racerguy" are not for the 1997 2Valve Engine (maybe for the 3Valve!!??)
