Knock After Timing Set Install
I should have left well enough alone. I removed the Pete Jackson Geardrive timing set after only 200 miles, and replaced it with a True Roller double row gears and chain. It made too much noise. It sounded like my Ford Lightning at full boost, but all the time.I used the timing cover that had been modified for the geardrive setup. This consisted of removing the casting that protrudes in between the cam gear and crank gear on the inside of the cover. I don't know what Ford put it there for, whether it controls oil flow or what. Anyway, when my truck is cold, there's no noise. Once it warms up, it sounds like a there's a knocking noise in the front of the engine. I can only hear it at idle, but I know something isn't right. I was wondering if I could have screwed something up while installing the timing set(installed 10 or more timing sets with no problems)? Or maybe if I install an unmodified timing cover, will my noise go away? What does that angled flat casting do?

i think i read somewhere that the angle casting part that protrouds from the timing cover is in place of an oil slinger. I think my 289 uses a circular slinger bolted to the camshaft and it does not have that angle piece on the timing cover. My 302 has the angled piece and does not use an oil slinger. Just an idea, i would double check with someone who is sure before you do anything.

Do you have a mechanical fuel pump? Maybe it's making the noise somehow. Also consider the noise may have been there all the time. You may have never noticed it with all the gear noise before.

[updated:LAST EDITED ON 26-Mar-02 AT 09:42 AM (EST)]you might have excessive end play in the camshaft now and the timing gear is hitting the housing you put on you might need a cam button so it doesn't hit or give you the knocking noise
