Finding bad lifter? March 17, 2008, 05:21:57 PM So everything on the car's great other than when it sat for 2 weeks, I went to start it up and one lifter was making noise for about 5 minutes before it quieted down to be no louder than the rest of the motor. How do I find which lifter this is so I can replace it? They're Melling "Made in USA" ones but perhaps I should pick up some Crane lifters or something instead and get rid of these?Btw, the 4 made in Mexico ones I saw at once place looked tons better than the made in USA, which looked like the original ford pieces - scratches on the side and all. I was surprised. Quote Selected

I would think though that with the right lifters and rockers, the valve train could be made quite silent.I hear valve train noise after its warmed up and I WOT it though - I would think it should be quieter than this on a new motor with new valve train and tons of time spent shimming the rockers perfectly. I've heard the Crane Energizer rollers are typically noisier though.Motor's a '89 GT cam, -7.4cc pistons, flattened deck but not to zero, factory replacement lifters and pushrods, cobra gt40 heads and intake - done at 30/10/10.

Reply #3 – March 18, 2008, 12:23:10 AM to isolate, and without removing parts, pop the hood and listen to which side it is coming from.fetch a wooden dowel and put it to the valve cover and to your ear.listen to the noise and isolate its location with respect to which cylinder.to keep it tapping longer since you say it gets quiet after about 5min, i would adjust the idle low with a cold motor so it does not warm up as quickly. this might give you time to make it around the car on each cylinder.or......if it were not for that stupid upper intake, id have you remove both valve covers and use your hand to put presure on each rocker arm as the engine runs. when you make the noise go away with presure on the pushrod side of the rocker, you just found which lifter.Shims under the springs really wouldnt do much for lifter slop as the shim just makes the valve seat tighter to the head. If anything, it will force more presure on the lifters to open the valve a tinnny tiny bit later than normal.all you deep freeze folks should be running a thinner oil in the winter to help prevent this. Thats just my opinion though. Quote Selected

Finding bad lifter? Reply #5 – March 18, 2008, 05:55:15 AM you can try what we do at the shop for a cheap fix to a ticking lifter. works 90% of the time. 1 bottle of stp oil treatment and about 1/4 bottle of marvel mystery oil. sounds crazy but it really does work. Quote Selected
Finding bad lifter? Reply #6 – March 19, 2008, 12:19:14 AM Ive also heard of running 1/2 qt of atf in the crankcase before an oil change to achieve the same effect dudeman351 said. I, however, have not done this. I hear good things and bad things about it. Mostly good things, but there is always nay-sayers. Just a note, I, personally have never done this. I did have a friend with a solid lifter 6* mustang that did. Quote Selected
