valve cover bolts

[doom26464]

So I took the valve covers off today and when I was taking the bolts of i noticed they came off really really easy. Now shouldn't these bad boys be on there pretty tight? is that why there is tons and tons of oil in my spark plug valley and inbetween the vavle covers??


pretty noobish questions but mabye a simple answer will complete this simple questions :aigo:

also the head is brand new(only like 10,000km on it) along with the valve cover seals

They shouldn't be really tight, just snug. Most like though the reason why you have tones of oil down there. Over time, they do become loose cause the rubber grommets for one harden and shrink and two, the actual valve cover seal does the same thing especially on the exhaust side cover due to the additional heat on that side.

Me personally, I resnug (well atleast check and make sure that non have come loose) mine every time I change the oil. A few extra minutes of preventitive maintenance.

no, they shouldn't be too tight. but they should be tighter than they were. get some good stainless steel hex head bolts and new cove washers. i never torque those to the correct setting, but rather when i feel they are "tight enough".

everything else on the motor, i actually torque correctly. i'm not sure why i do those differently.

yes, if they are loose, that's where your oil is coming from.

M6X1 is the thread for sure, 25mm length I'm not so sure of.

I torque the the proper torque setting, I used the rubber grommets with SS bolts

LOCKTITE THEM!

6x1mm 27mm long to be exact

I got stainless hex cap bolts from Ace Harware...used an inside star washer between cap and grommet. Torque is 22 in/lbs (not ft/lbs!)

Yeah...a 30mm length should work fine. The cap heads look really good though

Buttonheads would be nicer

Like these:

Those do look nice too!

Yep I use those anyplace they don't need to be torqued down hard as they use a smaller key that's prone to stripping if you do em up too tight.

Hey, the boltdepot. I buy from them. Recently needed a couple of M10X160 for a project on the devil car and they were the only ones who had them in small quantities. Shipping was a killer though.

 

[jdub]

Yeah...they have a good selection. They do charge a bit on the high side for shipping though :icon_conf

If you need it, they gotcha by the cajonies.

I have a local guy that stocks all weird and wonderful things

He had my 9mm x 1.25 bolts for the Tq Convertor in stock, only place in Australia that had em

I need to replace mine as well. When I was doing my BHG I ordered a valve cover stud kit from horsepowerfreaks.com. However, the studs didnt fit at all, they are to big and wont thread into the head. oh well
