Lifter replacement (clearance)

[shadowdrag]

I was reading thru Vfaq, and on the third page, it states

( Beware: Screwdriver clearance is very tight on the two valves closest to the cam pulleys, so make sure that yo can get leverage to put the rocker arms back on before you remove them, or else you may end up taking off the timing belt and cam pulleys to get them in there.)

Did anyone have this problem when doing it? I know I have never did a timing belt job and when I saw my brother did his, he blew motor for bad timing.

Because of this, I am having second thoughts of doing the lifters, but I do have the new set of 3g lifters here and would waste my money if I didn't do it.

Don't worry bro. It's all doable and not nearly as hard as it may sound. Make sure you get yourself a BFS (a big fvcking screwdriver) and a rubber mallet, to use as a leverage point. You put the mallet on the spart plug hole, and pry rocker arms using that mallet as a pivot point.

Reading this whole thread might help you a little. It's fairly easy, I don't think it's a 'cinch' as other people make it out to be, but it wasn't too bad. You will get mad though at the damn rockers..getting them off is the easy part, getting them back on will make you throw shit. have fun!

A little magnetic pick-up tool is your best friend while doing this! Also be careful not to gouge up your camshafts...a crowbar really helps too, more than a big flat-tipped screwdriver. I only used a big screwdriver to push the lifters down when the edge of the rocker was just almost over the lifter, but not quite..

I am on my las row of lifters, but the cam is blocking the rocker. Is it ok to turn the CAM to a position that I want and not break anything.



Thx

Obviously you'll need to rotate the engine to get cam lobes off the rockers every now and then. Just don't do it by spinning the cam. That has a tendency to skip a tooth or two on the timing belt. Always rotate at the crank.
(I'm assuming timing belt is still on)

I had to rotate one cam 360 to get the cam lobe off, but I rerotate it back to the same position everytime I'd put back on the rockers. Just finish and took the car out for a spin and it sounds great.

How to tell if I skipped a tooth and how would the motor react to it?

Thx much, I'm still a noob when it comes to dsm timing.

Depends haw many teeth are skipped.

one will make your car read a lot of knock and feel 'retarded'
two will make is sputter and missfire
three will bend valves and shut it down for good

Normally you feel if you skipped a tooth when you manually rotate camshaft.

Thx for the info, Im kinda frighten now. My car seems to drive normal but I have no clue if it is knocking or not. I do have the eprom knock sum but I haven't seen it jump too high, maybe 1 or 2 the most when accelerating. This morning, my car turns on really nicely and quiet tho. I think I might take it in to get it check or maybe someone is helpful and patient enough to walk me thru the steps.

You are fine, don't worry.

I'm talking max knock around 2500rpm. You'd feel such a power loss, that you wouldn't think your car drives fine.

Couple of things comes to mind.

1. Did you prime the lifters? If so, did you bleed them before installation?

2.

You didn't rotate it CCW did you?

Good point. Rotating counter-clock-wise is a no-no. (Although I did get aay with it back in the day).

1. I don't think I did this. I just remember VFAQ said to put in the new lifters same way it came out. I just wipe them down like VFAQ stated prior to the install.

2. There was a time where I did have to rotate it CCW to get the lobe out, but after the new lifters went in, I went ahead and rerotate the cams back. But I don't think I did a CCW 360 on it, just a little maybe 10-15 degrees and it wouldn't let me go further so I stop.

Rotate from the crank CW up to 6 rotations and line up the timing marks before you fire it up.

Sorry Oldman, I've fire my car up yesterday and i drove it to work today. It seems to run fine but I wouldn't know until something goes wrong. I have not driven it hard yet, just normal driving.

When I get home, I'll open up the CAM Sprocket cover and inspect it. , I wouldn't know what to look for if I open it, so please do help.

 

[oldman]

You should be fine but to double check, follow this article, skip right to step 8 in how to put the engine at TDC and line up the timing marks on the cam sprokets as well as the harmonic balance/crank pulley without removing the lower cover.
