Im wondering if these have enough adjustment to compensate for the smaller base circle of reground OE cams.

Which way does the small hole face on the valve lash adjuster

@mrtopcat2 2 жыл бұрын

The problem that I see with the 'popping-out' method, that it does laterally push the shaft of the valve and thereby applying a bending force to it. I understand that you and others may have done it this way many times over and hence are comfortable to conclude that this may not be enough to bend a valve. But who knows for sure(!) It does not take much for a slightly bent valve to get stuck and hit by the piston. The "popping-in" method seems OK and actually quite smartly executed.

A bent rod or some other part hitting the piston, you would hear noise.

Been doing a lot of research on this subject and from a few sources that NPI lash adjusters bleed down faster then PI lash adjusters with 4V being the fastest .. (coyote engines are different apparently?) if you are doing a PI intake and cam swap on a NPI engine sourching the parts from a junkyard PI crown vic grab the lash adjusters while you are there because they are superior to the NPI oem adjusters.. also if ordering new adjusters for 4V ..get NPI adjusters .. if you simply order them from an aftermarket company you might be getting the faster bleed style 4V ones when this is a chance to upgrade to the better design.. comp cams has lash adjusters with slower bleed down rates and they cost a ton of $$$ who is to say they are not repackaged ford oem PI lash adjusters or they simply went direct to the oem supplier for the upgraded design ?

Do these cause a tick when they go bad? Or is that more from valve seals? How would you know they were bad without taking the engine apart?

@aaroncornack Жыл бұрын

Yes they start to tick when going bad. Take something long like a breaker bar, crow bar, or a very long screw driver, and turn on the engine. Take whatever tool you're using and place it on the valve cover, so that it's phystially touching the valve cover. Place your ear on the other end of the tool and listen for an odd noise. Most of them will sound the same but the one that sounds different is nearby or the one that is starting to fail or has already failed. Very important to replcace then ASAP as it could drop a valve and destroy the engine. It could also be the phasers for the VCT mechanism. If you want more info, @FordTechMakuloko has some videos talking about them and how to replace them.

i own a 2017 Coyote, it still has a warranty, so the dealer is going to deal with it, but the question I have is, do these tend to fail often? I do not seem to remember these failing in my 2007 GT with 130k miles and mine in the 2017 make noise when I first start the car for a brief second then goes quiet like the lash lost fluid or something. I was going to look into if I should bother getting the Ford Performance version and hope they will install them under warranty if I paid for them

@dannyjohnsonsgarage Жыл бұрын

If they give the instructions to prime, I would imagine it’s for a reason. You submerge them in a bag of oil and prime them by putting an Allen key in the head and pumping. I would also hold the gas pedal to the floor while starting the car so it will prime and not start.

@thecrackfox3516 2 жыл бұрын

How did you determine these were bad? I am in the midst of a rebuild on one of these and the haynes book says to put a paper clip in the hole and it should release the check ball and allow you to manually bleed out all the old oil and ensure that they are not stuck/can pump back up after bleeding down. I cannot for the life of me get any of mine to do that. I even soaked one in acetone overnight. Makes me think they are bad or I am stupid lol

@dannyjohnsonsgarage 2 жыл бұрын

I put an Allen key in the nose of them while submerging them in motor oil and pumping. It’s also supposed to prime them, but they are hydraulic, so like a bottle Jack it’s hard to tell if they hold pressure until they are running. They should pump if they aren’t locked up. I followed the Haynes steps too but it’s hard to know if they are good or bad

I have a 95 mark viii dohc motor in my 67 f100. When giving slight revs, I'll get a ticking done from the passenger side that will lessen after a few seconds. I assume it's a bad lash adjuster. Does that sound right to you? Is the fix similar?

It would be a similar fix if that’s it. I would take the cam cover off to investigate. It could also be a timing component, so listen around with a stethoscope kzfaq.info/get/bejne/jduKf5p1uMvOaXk.htmlsi=A7XcqWAECo2sSYfs

@@yarkie1 I can’t recommend it, but I have before on the 2V engines. It will splash a little oil, so make sure it doesn’t get on the hot exhaust. At idle it will be flicking some oil around but for a short time you’d probably be fine. On most cars you can put the accelerator to the floor and then when starting it will crank and not start so you could watch the valvetrain that way. Of course be careful in case that was not a feature for 1995.

How to tell it is bad and need new ones? thanks

@dannyjohnsonsgarage 2 жыл бұрын

New ones should be firm when you push down on them down and rise slowly but I haven’t had any really go bad on me. The ford manual says that a properly functioning lash adjuster should bleed down in the 5-25 second range. So, if you can depress it with your fingers and it springs right back, it's bad. If it takes longer then 25 seconds to bleed down or less then 5 seconds, it's bad. I believe you need to remove the oil first so they should be dry to test. You’ll want to soak them in new motor oil, put an Allen down the head and push the tops up and down to prime them before install
