Hello fellow rover-ers

I have a noisy lifter and need help. I added sea-foam to the oil, and it actually eliminated the lifter tick. Then it cam back a little stronger than before. So I figure I an going to replace the lifters. Has anyone messed around with these before? I plan to remove intake and valve covers, loosen rocker arms, remove push rods, and extract lifter. I then plan to have the new lifters soaking in oil for about a week to get them as saturated as possible. I am open to any insight to make this go easy. i just cant stand that ticking! If anyone has any other ideas that may help, let me know as i am open to other options.

 

Have you checked the oil pressure? Perhaps that's low and causing them to tick? Maybe your oil pump is going bad.

 

no i haven't. Where do you get a gauge and where do you put it?

 

well.......the sad fact is that the lifters wont come out without removing the heads..there wasn't designed enough room to get the lifter through the head, and even if there was the lifter may not just slide out of it's position due to wear on the bottom of the lifter, BUT there is some good news......It may not be a lifter, ( if your heads arent leaking and you dont want to tear into that yet ) I have found that a lot of top end noise is due to years of wear on the rockershafts / rocker arms / and pushrods, on these engines there are only a few thousands of an inch wear between noisy and quiet. I went through basically your same situation a few months ago and ended up replacing the rocker shaft assys and push rods.....now it sounds like a different engine. Remove the valve covers and remove the rockershafts as you were going to do anyway....look them over good and if there are ANY signs of wear its probably time to replace them as well as the push rods. the parts needed are available a lot of places...I got mine from AtlanticBritish.....$300-$400.

 

well would me being able to reduce/eliminate noise for a while pertain to the rocker shafts and push rods? or could that only be a lifter. I thought the lifter wouldn't come through the head, I would have to remove the intake to get to them, but still not remove heads. Not true?

 

AFAIK you do not have to remove the heads to get the lifters out. Get the valley gasket off and remove the rocker covers and the rocker shaft and pushrods. That gives you access to the lifters they pop out or there is a tool you can buy.

 

what is the tool?

 

Don't worry about replacing your lifters. Pop off the valve covers and clean out the rocker shafts. After cleaning, if t you still have a tick, listen to where it is. The wear caps on the rockers can cause a light tick if they get loose. Listen to the tick and you can tell where it is coming from. If it is a loud dull tick, it is probably coming from the lifter which could be starved for oil. If it is light, it may be from the rocker shaft.

Regardless, start from the rocker shaft and work your way down so you don't have to tear into the engine any farther.

What weight of oil are you using?

 

I am using 10-30 pennzoil. how exactly do i get inside the rocker shaft? Do I remove the whole assembly? You cant hear the tick unless it is at idle, it is very light. You cant hear it in the vehicle either.

 

download a RAVE manual and it will have the instructions. Sounds like a cap to me, but you will need to tear into it to figure it out. Might make sure it isn't an exhaust leak either.

You have to remove the shaft to clean inside, but it is built in sections.
