I just installed an e-cam, FMS 1.6 Roller Rockers (ped mount), and valve springs, on my 5.0.

After starting the motor there is a very noticable tapping on the drivers side valve cover. You can actually feel the vibrating when you put your finger on the cover. The passenger side sounds/feels fine. I pulled the valve covers off and verified that the rockers were not hitting the covers. So what else could it be?

All the rockers were torqued to 17lbs. I used the stock lifters and pushrods, and the motor only has about 9k miles on it.

Tomorrow I plan to re-torque everything and check the pushrods. Any ideas??

you got a 96' 5.0?

::shrug:: did you adjust the valves?

what procedure did you use to adjust/shim the pedestal rockers?

Also what valve covers are you using?

I found TDC for each cylinder (in firing order) and finger tightened it to 0 lash than set it to 17 ft lbs (about 3/4 of a turn). After tearing the motor back down to the heads, checking the torque again, and reassembling (with the valve covers off so I could see which one was the problem) it started right up and ran/idled perfect). So it must have just needed to run longer. So once I tore it back down to put the valve covers back on, and reassembled, now I have a vaccuum leak (or its missing)! ^%#&@$$#@ The idle just sounds really bad, not like it did, and it takes a few cranks to restart the motor and once its started it barely idles.

So I'm tearing it back down tomorrow.

Any advice? Yes, I have a '96 5.0.

I think your eec v really hates the e cam.

I thought that at first.. but I know of three or four other guys already running the ecam in their eecvs.

But when I started it up without the valve covers on it ran like stock. So I know its possible to get it running right. It was smoooth as butter. So I'm pretty confident its a vaccuum leak or its missing.

I have stock exhaust on it right now and it still sounds bad ass.

if I had to guess your vacuum leak is on your lower intake seal, did you let the RTV 'set' for a good 10 minutes before you *carefully* guided the lower intake down hopefully over studs or whatnot?

Yeah, it's gotta be something on the upper. Cause once the lower was on, I never had it back off. When I tore down to take the valve covers off, I only took off the upper. So I'm hoping its something behind the upper that I am missing.

When I take the upper off tomorrow I'm just going to really check and make sure I see everything that needs to be hooked back up. So far I'm 1-3.

I'll get a vid right now and show you what it's doing..

Okay, it's not vaccuum.

Cylinder #1 and #5 are not injecting fuel I believe. When I take each of the plug wires off the coil packs individually, those two are the only ones that didnt affect engine idle while off. The coil pack was igniting those two wires and the spark plugs. I changed both wires and spark plugs to make sure it wasn't those. It wasns't. So I'm getting a noid light in the morning to confirm its those two injectors or injector wires. I'm thinking they share the same ground or something and that is the problem.

Anyone know anything more?

You didn't possibly cross any plug wires by accident did you?

Posted by section525 (Member # 2819) on :
 

To be honest, my buddy hooked the wires up. Let me go check!

EDIT: Nope, wasn't it. I reversed those two and it still started up the same. Plus, I haven't removed the wires since we first got everything back together.. and it did run perfect after that. I'm getting a noid light in the morning and I'll test the actual injector harness.

Why not have the EEC do a cylinder balance test?
