has anyone else have this problem? was changing my oil and I was unscrewing the cap when the whole assembly screwed off the valve cover. When I looked at the threads I noticed that they were all cross threaded and suspect I couldn't get it back on properly. Went to the local dealership, got a new part and was going to screw the new one on but thought, if the old on was cross threaded, maybe some of the plastic thread bits fell in. Should I take the covers off and clean them out while I'm at it? Also do you think I should be some sort of thread lock on the assembly so prevent the filler cap and extension for coming off in the future? take care sam | ||

Its quite a job, you have to take off the plenum and a bunch of hoses. But its worth taking the rockers off and cleaning all the sludge out every few years anyway, it will keep the oil splashing around. You'll need new rocker cover gaskets. Dean | ||

Dean, (or anyone) After you remove the rocker covers how do you remove the rockers and clean them. Also, can you tell me how to replace a rocker? | ||

Rocker has 4 bolts on the pedestals, very simple to remove. Make sure the push-rod cavities are nice and smooth and shiny, and the rods are ok, and the bearing races are nice and tight. To clean it you could basically just wipe it down with a bunch of rags, maybe soak it in a solvent and then re-oil it. But the rockers sit on the top of the heads, which also fill up with gunge, needs a clean. Clean the oil ways and breathers, you'll see. | ||

If you take out the push rods to clean/inspect them, make sure you seat them back in the hydraulic tappets properly. Hold onto them too, it's a pain in the ass if one falls down inside. | ||

Matthew - could you get all of your tappets to squash down (compress) if you pushed them hard enough? I'm not sure if they are supposed to all be springy at the same time. Does it depend on the cam position? Only some of mine seem to be bouncy. | ||

Happens all the time on DIIs. Don't overtighten the cap and it should not be an issue. I would not be concerned. Dean if when you shake your tappet it rattles then it is bad. Not sure how you can check them insitu. Ron | ||

I never really checked that when I was putting the push rods back in, Dean. When I pulled back on the push rod, the tappet would extened out due to the suction between the two from the oil. I never pushed down on the rod though, so I'm not sure. p.s. Rob, If you do remove and clean the rods, makes sure you keep them in order. Take a thick piece of cardboard, and poke holes (2 rows of 8) in it. Place them in the same order as they were removed. Don't forget to label the cardboard "front" or "rear" so you know what side they came off of. Brake cleaner worked really well to clean them also. Matt |
