Spec calls for 2 stages, but the next day when I go back to the bolts, there is no torque on them so I have learned to torque them again the following day. Maybe this is why so many owners have problems with them. Hell, maybe it's because I broke the Loctite bond on the 2nd torquing stage, I really do not know. But with that being said, maybe more investigation should be done to prevent future issues with loosening valve covers. I saw a Loctite Green (unsure of its application) on the shelf yesterday. It all comes down to using a thread sealant/adhesive that allows torquing in stages to compress that thick A$$ gasket.

As for your earlier question about copper/sealants on the cylinder side of gasket, that side I left completely dry. The copper is just to hold the gasket in place on the cover but it doesn't work most of the time as there is some finagling with it on the Rover. The main thing is just getting that gasket seated properly between the head and the cover; the lip can get squished underneath and you are screwed if you aren't looking for it.

I really like how you clamped that cover to the table; way better than my sitting it on the floor! Have you put the covers on yet? I have always done that manifold gasket dry, but I'm either going to double them up this time, or use copper on the upper manifold side/ dry on the lower manifold side. The face of my upper plenum is not perfectly flat and I'm concerned that it's not sealing completely. But that's just my situation. Would love to have dropped that off with my other parts at the cylinder shop but in my haste, I forgot to inquire about it.
I have not yet. The cold shrinks the Gasket that's why I could not do it yesterday. Planning on putting them on today re-torque hour later just so the Locktile does not dry up. will attempt tomorrow again.

I am going to follow your advice on not using on the Head side. If the sealant sticks good then next time cleaning is going to be a bitch. covers are easy to clean as they are out.

By the way how do you clean the upper Intake? Break cleaner? I have been using paint thinner with a rag works like miracle.

Thanks Man

Very faulty design. heavy cover held by very weak screws. I am replacing them with little larger 6 points head.

This, proper torque is key.

Has anyone used lock washers on the valve cover bolts and then torqued them to spec? Possibly using Loctite blue as well?

Mine are leaking now and I'd like to do the job once and have them stay tight & dry!

I ordered the replacement bolts with orings off of eBay and then used loctite blue on mine. Torqued em in 2 stages and doubled checked em. Can't give any real world results BC I'm doing that as part of my head gasket repair.

replace your VC bolts with the O-ringed design that Lucky there has and you should be leak free for a few years until the replacement gaskets begin to harden again.

O-ringed design? Does anyone have a picture of one?

Off of eBay for $19.31. They are made by uro though. Not a fan of their parts but cheaper than the brittpart ones

i had had the head shop dip mine in the chemical bath to get all the carbon out. If you have access to a parts cleaner, let it soak in there or seal the stuff off and pour some sea foam in it and shake it vigorously and it should break up a ton of it. Or you can use the paint thinner and use ziplock bags and tape to cover all the openings and put it in and let it do its job.
