Just wondering. I have a loud ticking noise in my engine. The guy at the dealership said it was the rocker arm cupplings. He said there was 16 per side and i need some sorta plate? Does anyone know the name of the plate? And maybe where would be the cheapest spot to buy this plate and the cupplings? Are they called rockerarm cupplings? He said the ticking is alright and doesnt affect the perforance of the truck, but it is driving me nuts...So i need to replace them..... A buddy of mine is a mechanic, so he will do it for me.••••••• help would be great Thanks Sean | ||

The whole assembly is $75 at your dealer per side (one part where the dealer is cheap), plus $12 a pop for the valve cover gaskets and about $2 per for the special screws if you do not have the new style already. I am not sure what a rockerarm coupler but I know it is not in my parts books  It could also be a colapsed lifter, what year is your truck? Ron | ||

Assembly? Do you happen to have the part number that i might need? My discovery is a 96. Im not sure if I have a new style or not. See the thing is Im am not near a dealership. I am in Labrador. And I have to get the parts shipped in via airplane. Usually takes 3 days. So it would be bad to not have all the parts I need. Cause then I would be waiting. " The whole assembly" what does this include? How many valve cover gaskets do i need and how many special screws if needed. Is there maybe a diagram somewhere that i could se of the parts i needed? The ticking is louder on the right side, but I want to do both sides anyhow. Also is there not a some kind of plate that i need? Thanks Sean | ||

Does your disco sound like a diesl, because mind sounds like it and I just had the engine rebuild. That noise also driving me crazy. I have 95 disco. The guy who did the work said it would go away over time and that the engine still needs to break in. | ||

611660 I think You need to figure out if it is a lifter or a rocker arm, when does it tick? Ron | ||

Pull the valve cover off and check the rockers. Take off the bolts to the shaft that retain it to the head. They can be used again. Lift out the Assy. Use a pick to see if any of the cups wiggle around. Also, check the riders and shaft for wear. The shaft can be checked by sliding the rockers aside to inspect. The riders are on the other side of the rocker from the cup. If any of this is worn or loose, replace. $58.44 per Rocker Shaft Assy $8.70 per VC Gasket $1.52 per VC bolt Special Disco Web Price 610-692-5107 Ask for Mike For the lifters or tappets as they are sometimes called, you will have to remove the head to properly inspect. Some lift up the intake and gasket to check but you can't really get a good look with out lifting the head and inspecting each one by hand. Not eyeball. Unless it is totally obvious and completely crushed. | ||

I have no idea what "Plate" he is talking about. | ||
| Ron Brown (Ron) Senior Member Username: Ron Post Number: 513 Registered: 04-2001 |
Mike is right except you do not have to pull the head, once you take off the intake the lifters are accessable and you can inspect them. The easiest test is if they rattle when you shake them they are toast. Ron | ||

Ron you are kind of right. However you can't get the lifters out with the load of the rockers/valve train pressed upon them. You can lift the intake but have to remove the rocker shafts to allow enough clearence to pull out the lifters. But you know me. I like things done "the right way". Especially if it is my personal truck. Lifters $11.00 each Special Disco Web Price 610-692-5107 Ask for Mike | ||

" you will have to remove the head to properly inspect." I think the reason we are not seeing eye to eye on this is that there is no reason to pull the heads, only to pull the rockers off the head which is a given (I think this is what you were talking about not pulling the heads themselves). Procedure would be valve covers off, intake off, rockers off, pull out push rods, remove lifters. No point to pulling the heads as they do not give you anymore access, unless of course you have another reason to pull them. Ron | ||

O.K., I have a '90 RR 3.9. It developed the loud tick rather suddenly and thought it was a lifter. I would probably be driving it today had I just replaced the rocker arm assembly for $99.00 per side(no plate) and a lifter or two...BUT NO - I came down with a severe case of "Shipfitters disease" and am having the engine completely rebuilt. Actually, it needed it. One of the rocker arms had the steel insert, that the pushrod contacts, loose its set and get pushed inward >1/8". Thats prolly all it is. | ||

Ron You're right. You don't have to remove the head. But lets not get stuck on one issue here. The fact is that you can't just lift up the intake to inspect the lifters. Further disassembly is required. But after the 26+ bolts already removed, whats 20 more. But, you know me. I would do the valve job and work the heads if it was my truck. Or, like I did when it was my truck. Ha Ha. | ||

I�m also experiencing a loud top end ticking noise (start once the engine warms up), my 95 3.9 runs well no oil lights etc. just the ticking. My mech. Is at a dead end with this and recommend I have the engine rebuilt (having it pull next week). He inspected the rocker arms and said they check out! Also said my Oil pressure is ok (something like 44psi). but he thinks the ticking is cause by oil not reaching up to the values! Im still somewhat hesitant about a total rebuilding (2k vs. $300). Can it be my rockers also! | ||

I have the ticking also, not really noticable normally, only when i'm accelerating hard when getting on the freeway. My LR mechanic/friend told me it's the rockers. Doesn't seem like that would constitute a rebuild, but I dunno how loud your clicking is. | ||
| john heath (Jheath6) Member Username: Jheath6 Post Number: 111 Registered: 09-2003 |
almost any rover with miles ticks a little , thats just the way it is in rover land. | ||
| eric johnson (Eric2) Member Username: Eric2 Post Number: 125 Registered: 05-2003 |
Anthony - Check the main and rod bearings for wear. Just pull one or two and if you see any copper - yeah, complete rebuild. No copper - heads only. Epuffy - "not really noticable normally, only when i'm accelerating hard when getting on the freeway." - From your description, sounds like its only pinging(pinking) to me. No biggie. |
