Replaced timing chains but still wont crank

[Keith89]

Ok guys so I bought the new heads installed them and engine runs great except for one thing I am getting a rattle kinda similar to the timing chain rattle but everything is brand new . My oil pressure is strong .I replaced everything chain was tight I primed the tensioners they were tight I don't know what could've went wrong. Except for the rattle it runs great . Any ideas

Check your dipstick tube, it likes to hit a counterweight if lightly bent. Can you narrow it down to a side? I've see the oil rails for the cams bend and the cam lobes hit too.

 

[Keith89]

I did bent it actually now that you say it it is hard to get my dipstick back it once I take it out. So should I completely remove dipstick tube and crank it

 

[Keith89]

And the noise is coming from that side. Worth a try

 

[boominXplorer]

Just put your hand on it while running, you'll know if it's hitting.

 

[Keith89]

Ok thanks

 

[Keith89]

So I put my hand on the dipstick tube while running and I didn't feel anything no extra vibrations or anything but it is coming from that side. Idk I just don't see how it could be the chain it is all brand new. Even replaced the from tensioner just in case and nothing still the same. Would the oil rail hitting the lobes give the same sound as chain rattle

You might try pulling out the timing chain tensioner on the driver (bank 2) side--you can do this pretty easily if you pull the coolant sensor our of the thermostat housing--and checking if the business end is rock-hard (not "springy"). If that tensioner does not build up enough pressure to keep the chain taught, then you could get slapping even with new chain/guides.

Did you put in a new tensioner? Was it a Cloyes (OEM)? I recall having to pump the business end of that tensioner about 60-70 times in a pint gar of 5w-30 motor oil before finally getting all the air bubbles out. At that point I couldn't believe suddenly how stiff it became (like I said, almost "rock hard").

 

[Keith89]

I had replaced the tensioners when I changed the ti ing chains and guides. I thought at first I had a faulty tensioner even though it was brand new and bought another one.yes clouds. And yes I primed the heck out of it submerged in synthetic oil. When I was done it would not hardly move at all just barely would go down but was rock hard aside from that very slight movement

 

[Drewmcg]

Sounds like you did it right, but I wonder from the problem you're having whether it maintained pressure? Mabye somehow the small pinhole at the top of that tensioner, which sits slightly below the surface of the head, got blocked when you re-installed it, preventing maintaining pressure?

Like I said, easy enough to pull it and double check. If its still rock hard after running 5-10 minutes, you know that's not the problem. If its not rock hard, well, "there's your problem, lady . . . "

 

[Keith89]

My oil pressure is strong but I'll pull the tensioner back out and make sure it's still hard thanks

Pop the valve cover and have a boo.

 

[Keith89]

Ok so before I do all that I just have to mention yes I did prime the tensioner but did not use the tensioner tool ford recommends using before installing the actual tensioner could that have something to do with it. Also the tensioner I originally used when I put the cam sprocket back on and tightened everything down I don't believe was primed right. I know the second one was but I installed that one only after the noise started

 

[Keith89]

Yeah tensioner wasn't rock hard anymore that's the second one of the cloyes brand. Wouldn't even prime again once I took it out.so I ordered the more expensive one this time from carquest 77 dollars compared to 44 with cloyes. Is it really my bad luck or could something else be at play.

 

[Keith89]

I think I am over tightening

 

[Drewmcg]

finding the problem is most of the solution. this tensioner takes a paper thin washer. get it from a ford dealer, and don't use any thread dope.

Also there's a tiny port threaded with torx set screw about an inch or so rearward from the tensioner. There should be a long nylon (?) rod in there. It helps build up pressure in the tensioner. you might check that, or replace it if you haven't already. (nb: use thread dope on that set screw.,)

 

[Tech By Trade]

Just looking back, did I read correctly, that you used a tensioner to hold the chain taught when you installed the rear gear on the camshaft? If so did you epoxy the tensioner or somehow manage to lock it open?

 

[Keith89]

Not the rear the driver side cam sprocket and yes I'm I'm retarted I installed the tensioner then tightened my sprocket bolt. No it wasn't locked or with epoxy

 

[Keith89]

No I haven't replaced that nylon rod I was wandering about that my first tensioner came with it but the second one I bought didn't. Can you buy it separately
