Top End, CCV, and Valve Cover Questions..


Recommended Posts

OK, so I took the vc off today to clean my baffles and it was pretty crusty..

 

I took the 6 - 1/4" screws off the towers and when I separated them from the vc and the gaskets were done for.

Q #1- Can I just use some rtv in the small gaskets place???

 

I also couldn't help but to notice the top end of the head,(v-springs,push rods, rockers, rocker bridges, top of head) was bad crusty with some brittle carbon buildup..

 

Q #2- Is there any way to clean it safely without removing the head??

 

Q #3- Are the valves adjustable?? If so whats the high/low specs on them..??

 

Q #4- Can someone give me the torque specs on the cover and tightening sequence???

 

Thanks for everyones advice, suggestions, and answers!!!

valve cover bolts torque specs is 55 ft/lbs

 

Uh, might that be inch/lbs? :brows:

 

 

I know I removed most of the bolts with just a extension and socket, and it wasn't leaking.. The bolts weren't tight at all.

 

what about the crud on the top end? I really don't want to have to live with it.. that would drive me crazy knowing what it looked like under the vc :roll:

Jt, I just talked to a mechanic that told me that you shouldn't try to clean it with anything because he says anything you use might fall into the engine, drop to the oil pan, get sucked up by the oil pum, clog it and cause you more problems than you want. That's his advive if your not going to dismantle the engine. Sorry. Hope that helps a little.

cool.. well I guess I'll just close my eyes and put the VC back on .. lol

 

Did he say anything about adjusting the valves?? are they hydraulic, or solid ??

 

 

 

 

Just rechecked the chart. It is in/lbs. sorry.

 

Thanks,, I need a in/lb clicker anyways!! :brows:

Uh, Lucy, splain to me again why no cleanie the valve cover? How is anything going to drop down in the motor if you clean it, let it dry out or whatever before you put it back on???

 

I have cleaned the VC,, It was the top of the head thats covered in crud too. Like the valleys and rockers and ect,, Thats where the issue of some crap falling into the engine came up,, I would just pull the head, but I really don't want to remove the intake and exhaust...

 

So nobody said if I could use RTV on the CCV towers...??

yeah on the bottom side of the VC you'll see two towers (under each CCV hole) that holds a thin metal valve (baffle??) under it was a gasket, that just crumbled when the towers were removed. I read somewhere to just cut a paper gasket, but RTV isnt going to hurt anything is it??

That's a good question. Someone please answer because I'm probably going to have the same problem when I do mine.

 

 

Bump. I need to know this too as I am going to pull my valvecover off this weekend and clean it out to see if that helps my blowby issue.

 

Hey when one of you guys take your towers off the VC could you tell me which end has the baffle valve that has the bend in it?? One of those valves had a offset bend in it. I can't remember which end of the VC it was.
