Doing some maintance

[1993MTXSHO]

Well guys im going to be pulling apart this 93 atx I just got in a couple weeks. Im going to replace the leaking cam seal, take the valve cover gaskets off and rtv them, replace the busted brake line, replace the trunk seal, and clean the inside of the intake and egr valve. My question is, is when I clean and rtv the valve cover gaskets and stuff, how much can I tq down the valve cover bolts? I know the stock tq spec but I know those suckers break easy, so whats the tightest I can tq them w/o them breaking?

EDIT: oh yeah and im installing a D4U1

I usually just use an allen key and tighten them until I feel the bolt bottom out on the head.

 

[ohfosho]

oh if there are any cracks in your valve cover gaskets, or they are old and hard (or if they break when you pull them out of the cover), then do not even bother trying to just rtv them back to seal... i tried that... redid it all again in a few weeks

I can't imagine why anyone would remove the intake and valve covers and not replace the gaskets with new ones, I guess you won't do that again!

Would it be OK to apply anti-sieze on those threads? I recall twisting off 5 of them some time ago. While I managed to get four of the broken bits out, I have always wanted to do something different to avoid that in the future.

I can help you imagination, its because the suckers are almost 100 bucks to replace

they break coming out too? Jesus maybe I should just leave the damn things alone and let them leak. The car runs fine for now, maybe ill deal with it when I start having mis-firing problems or something.

If your not careful removing them, you can strip the head of the bolt. So make sure the hex key is fully inserted.

 

[K-Dawg]

Antisieze might be a good idea to make sure the bolts are easy to remove, as long as they don't start backing out on their own.

Oh, and when removing the valve cover bolts, I use a hex head on a ratchet to make sure that I don't strip the bolt heads.

Sometimes the valve cover gaskets are very dried out and brittle and they break as you are removing them. Sometimes they are fine to reuse.

No need for anti-seize... If you lightly **** all your nuts and bolts like the manual states, you'll be just fine. That combined with a controlled/sealed oily atmosphere will work like a charm.

Guess why my valve covers were leaking in my 400$ sho?

The damn nubblet before me siliconed the whole gasket , even the plug holes.

SHOs dont deserve cheap-ass plaster repairs. Do it right , or dont do it. 72$ if you shop at the right place.

 

[93rev2sev]

Agreed. All that RTV will get squeezed out and sucked up by the oil pump. Hello clogged pickup screen.

If you don't replace the gaskets, you might be able to clean them up and retorque everything...that will last about a month.

 

[1993MTXSHO]

ok I guess ill just leave the covers on and let the suckers leak, I don't want to take them off and have the gaskets crumble in my hands. the intake couplers are pretty dry and starting to crack so the valve cover gaskets are most likely the same. This car looks like it never had maintaince in its 155k miles, so im gunna just leave it alone and add oil as needed. If and when i start having misfiring problems ill deal with it, thanks for he tips guys:thankyou: How about cleaning the inside of the intake on the car? Would carb cleaner work or should i not waste my time?

 

[K-Dawg]

What is cleaning the intake going to get you? Don't waste your time.

 

[1993MTXSHO]

a better running sho? doesnt that oil and crap in there hurt power and make the car run worse?

 

[Devin]

If it's really gunky I think it can hurt the air velocity, but I'm not entirely sure. That'd be a search for sure. I do know, however that it's just good practice to keep parts in clean, working condition.

 

[St Louis SHO]

Find a shop near you that uses BG Brand products and have them do an "Air Induction" Service. It works.... I've done it to mine, pulled the intake off and wow... Should cost about $120 or less.

yeah i would have it cleaned but im spending little to no money on this car. thats why im not replacing the valve cover gaskets, otherwise id do a full 60k on this thing. I was just gunna spry some carb cleaner through it and maybe run some atf through the fuel system to clean everything out.

If it is leaking just a little, you might try one of the "high mileage" motor oils. They have additives that soften and slightly swell old hard seals. It can provide a temporary fix for slight leakage.

The cylinder head cover bolt torque specification in the FSM is 8-11 ft-lb. I used my 1/4" drive in-lb torque wrench and torqued them to 96 in.-lb. (Thats 12 x 8 ft-lb to convert the units to in-lb).

i dunno the thing leaks petty good, although thats not a bad idea I didnt think of that. I think ill run that high mileage oil anyway because this thing can really use it for all its seals
