Help with low power

[07navi]

I found one bad lash adjuster and both timing chain tensioners are blown out. I'll pull the front cover tomorrow and go from there.

When both blow out it can drop the oil pressure and mess with the VCT's etc. but it's usually one that goes. Ford didn't change that until they came out with the eco-boost. If a chain jumped a tooth that will explain the low power.

Hell when one blows out just a little its enough to cause issues. Probably because of the just barly adaquate oil pump in this turd.

This caused a lot of VVT issues on my truck.

The new oem tensioners have an updated O-ring

It needs an updated tensioner system...……...or maybe a blue one.

What blue one?

What blue one?

Just joking about that fact that the color change was supposed to be the fix-all.

Problem solved. I installed a full timing set, minus phasers, along with a melling m340hv oil pump and all rockers and valve lash adjusters and I'm back to full power. Not an easy job but fordtechmakuloco's videos explained everything very well.

Did you have a lot of bad rockers? Mine were all perfect to my surprise. I still have mine apart while I wait forever for this spring compressor tool to arrive to insert the rockers back under the cam. Nobody locally carried it unfortunately so I have to wait online. Amazons fastest delivery was May 23rd with the supply chain disruptions. Found one finally on Freedom Racing that I can get this month lol.

It probably jumped time causing the loss of power. I assume you put a chain in but do you really think it needed it? Mine was like new at over 200k miles.

How long did it take? Any prior experience doing this sort of thing, or just unrelated and less complex driveway wrenching?

I only had one failed rocker. Some others felt loose but we're still working. I got a set of off brand tools from eBay much quicker than Amazon could deliver. If you're replacing lifters then you have to pull your cam. Before you reinstall it, figure out which rockers will be compressed in the timing position and install all of the other rockers while the cam is loose so you don't have to fight with that tool 24 times. I only had 5 that needed installed with the compressor after the timing was set and the cam was torqued down.

Both Banks were still in time. I believe the phasers weren't advancing due to lack of oil pressure because of the blown tensioners. The chains had some wear but would have lasted much longer. I replaced them and everything else under the timing cover because I never want to take it off again.

The work took a few days. You need a good selection sockets, extensions, and wrenches to get to all of the bolts. And a small torque wrench. Some of the bolts only take 7 ft-lbs. I've worked on motors before but this is all fairly simple wrenching if you take it step by step. Keep everything clean and torque the important parts to spec. And watch the video series fordtechmakuloco has on YouTube before you start.

Days like a couple hours with beers or days like 14 hours till your hands cramp up?

Days like a several 8 hrs each. Having an over the top creaper made the job easier. It's not easy getting access to the timing cover area from the top or bottom.

I 2nd this. Been living it for several days now. I’d say the most difficult part for me was that damn bottom oil pump pickup tube bolt.

I agree. I ended up laying under the car with my feet towards the rear to be able to get my fingers on it. But it runs great now so I guess it was worth it.
