Well I decided to replace my timing belt on my 95 Ls, and do all the work my self. This is my first time doing this project, and I have come across a little problem with some slack in the belt. I am able to get the new belt on fine, but when I tighten the tensioner, there is still a lot of slack in the belt, so much that I can slide the belt back and forth on the cam gears. Is this normal? How much slack should I have on this belt, as it says nothing in the Helms manual about this. The belt is a 14400-P7J-004.

 

Where is the slack at? if it is on the exhaust side of the engine then the belt is on incorrect. I just changed my timing belt on my DA, when i first put it on there was about the same amount of slack. I had to take the belt back off and re-adjust it there should not be much slack at all.

Hope this helps,

Did you rotate the engine twice with the tensioner bolt loose to remove the slack?

That is what I ened up doing to remove the slack, and it worked good. I guess I over looked that step while doing it. Lesson learned!

Now I have another problem with my valve lash adjustment. It seems that pistons 1, and 2 adjust fine on both the intake and exhaust side, but when I go to do pistons 3, and 4 the exhaust side will not adjust at all, no matter how loose I go, I can not fit the feeler gauge in between the valve and cam. Have any of you experienced this?

 

Do the rockers have any play when thay are loose?

 

I didn't notice, but after I torque the lock nut, they wiggle back and forth? Is this supposed to happen?

 

Are you positive that the cams were in the correct position for cylinders 3 and 4?

 

Well I am second guessing my self, but I did go through #3 and #4 twice, I will have to try again tomorrow. I hope that, that is my problem, it must be, what else could it be?

 

Look at the cam itself to verify that the lobes are in the correct position. Are you following the procedure in the Helm manual?

 

Yes, I am following the Hlems manuel. As for checking to make sure the lobs are in the correct position, I will have to check again.

Maybe this is a dumb question, but if my timing was off, would this have anything to do with it?

Yes. The valves could be starting to open.

 

Even though pistons #1 and #2 seemed to be ok?

 

That is a good point. Why do you think that the timing is off?

 

I am not sure, I am almost 100% that the timing is correct, I am going to go give it another shot right now. I just replaced the timing belt myself, that is why I am second guessing the timing. All of the marks lined up at TDC when I put the belt on.

 

I don't know what I did last night, but I did it no problem today, I must have been too tired or something. No more chattering, it made a huge differance. Would I be able to tell if I screwed up the timing right when I initally start up my car? It seemed fine when I started it up.
