timing issues

[breeze]

Car keeps jumping timing. Had head off now on. Put all back together but the timing keeps messing up. We set the chains right for timing, linked the bronze links up how there supposed to be put back together and messes up again. What's the deal!!!???

Which chain. There are four. There are four tensioners to take up slack in the chains and it's possible one isn't working properly. I would guess it's one of the primary chains. Is it jumping teeth on the crank gears or the primary cam gears? I think if you slip a tooth on a crank gear, you jump 34 degrees, primay cam is 8.57 degrees, secondary is 18 degrees.

Having oil pressure issues?


Are you using the plastic or metal with ratchet timing chain adjusters? One guess which one is better. Ford Racing sells a timing chain kit that includes all new gears, tensioners and chains.

All is well, had driver side cams wrong.
