replacing lifters

[mysticfire]

how difficult is it to replace the lifters on a 95? do i need to remove the cam to do it on a metro? i cant stand the ungodly loud ticking noise anymore. and also, how much is it for 6 lifters? lol

6 lifters.. So we're talking about a 1.0L. Yes, you have to remove the cam to replace the lifters. If they're ticking, it doesn't necessarily mean the lifters are bad. You could be lacking oil pressure in the head, or there could be grime and sludge inside them. They are pretty easy to disassemble. All you do is grab the "nub" in the middle of the under-side of the lifter, and pull fairly hard. They're filled with oil, so be careful. Don't let them dry out! Keep all the parts dipped in oil. If you let them dry, they'll be useless. Also, when you re-assemble them, fill the "bucket" shaped part of the lifter with oil. Then press the hydraulic adjuster back in with your hand until you hear it click. No need to take the circlip off in the middle of the adjuster at any point. When you bring them back to the car, keep them submersed in oil, with the underside facing up. Make sure they're all assembled properly before installing them, or they'll fall apart when you go to put them in. They will tick like mad until they pump back up. If they're properly cleaned and re-assembled, it should sound great. If you feel un-comfortable taking them apart yourself(they're over $70/each on average) take them to a well-known machine shop or speed shop. Someone there should be able to clean them for you for a decent price.

aw crap, i was hoping you wouldnt need to take off the cam, because in my eclipse you didnt need too i wouldnt know if there is enough oil pressure going to the head, but how would i find out? i know when i take the oil cap off when its running theres enough pressure to make it squirt out like it should.

There's a hole in the front of your engine block right next to the oil pressure switch(triggers the light if pressure is too low). If you take that screw out, you can put an oil pressure gauge there. If your oil pressure is ~+25psi at idle, and ~+40psi at cruising RPM, you're ok. More is better. Just because oil is getting to the head, doesn't mean it's getting in the cam journals and in the hydraulic lifters at high enough pressure. Honestly, pulling the cam is pretty easy. And you have an opportunity to change your timing belt while you're at it.

hate to tell you this but after looking at a few "ticking" engines that i have replaced the noise ended up being a cracked piston skirt. if your oil pressure is fine in might be a piston

FINALLY!!!!!

i found out what the problem was, and it also happened to solve my idle surge and odd rattling noise at around 3k rpms. i am a tad bit embarased to admit what the problem was, but it turns out that the previous owner didnt have one of the spark plugs screwed in tight enough and was wobbling around freely. a totaly free fix.

LOL! Ya know what even funnier, I just tightened one of my buddy's spark plugs on his 2k Neon yesterday . He was complaining about smelling gas and his engine running like crap.
