hello i had replaced timing guides tensiniors and arms.. thinking we could get away without cam holders we skipped teeth. we timed it with what we thought was the timing marks closed it all up and put EVERYTHING back together and the truck wouldn't start.. does anyone have a diagram or something for timing? truck is a 2002 f150 4.6 vin 6 i believe. any help is needed. starting to tear it down again today..(ORDERED 2 CAM HOLDERS AND CRANK HOLDER) THANK YOU!

 

Yea, you really don't need the holders. Dynotech has a good write up, here -

we already removed chains and put back on but we lost timing i need a photo or somthing to show me how it should all be aligned. thank you

 

if anyone has any info could you please email me it??

 

I can send you an email tomorrow. Email me so i don't forget

It's really easy if you buy new chains. They will have the links marked that you put on the timing marks for the cams and crank.

If you want to reuse the old chains, it's still easy. Start with the engine at TDC on the compression stroke (crank mark at 6:00, cam marks facing up). Place the chain with a link centered over the crank timing mark, then count 29 links (including the link on the crank mark). The 29th link goes centered over the timing mark for the cam. It's the same for both sides.

Since you have to tear it all apart again, make sure you thoroughly cleaned the tensioners with brake cleaner if you reused the old ones. There's an oil orifice that lubes the chain and guides. They clog easily and are a cause of guide/tensioner arm failures. Use compressed air to blow through the oil orifice (very small hole) to make sure it's clear. Then put it all back together.

 

Lay the timing chains on a flat table. Place them so that half the links are against the other half of each chain. Just grab a link at approx both ends of the loop and pull them together so you have two rows of links tight against each other for each chain. The horizontal link at each end will be the halfway point of your timing chain that's the link you want to mark with a paint pen,the one on each end, it doesn't matter which two links you use just whichever links become the horizontal at the end of both rows of the same tight chain...then follow the procedure keeping the crankshaft keyway at 12:00 throughout the entire process..until after you release both chain tensioners then and only then can you rotate the crankshaft

 

thank you guys for your input we are hopfully going to start ripping the truck apart AGAIN tonight. im tired of driving my chevy want this ford done.

 

returned your PM Cody

 

think we bent a valve... timed correctly and started but really rough and dies.

 

Yep the first time you tried to start it and it was out of time a valve took a hit. perform a compression test on it before you remove the cyl heads so you can determine which cyl and which valves are bent.

 

tearing it down to the front cover and taking to a shop said if we tear most down woud save alot of labor, going to test and find out exactly what is wrong for 50$ then hopefully not too much $$$ to repair...

 

shop said bent valve getting head jobs done to both got quoted $2000 labor parts everything should be worth it. hopefully picking up my truck in a week
does 2k sound like alot for this?

 

no. it doesn't. 2 grand is fair for all that.
