Tightening up rocker cover bolts

[Colin RedGriff]

I seem to have a leak from the right hand rocker cover and so I want to tighten up the rocker cover bolts or if that doesn't work, replace the rocker cover gasket.

Anyone know where I can get my hands on a socket to fit the bi-hex bolts, and any idea what size? Looking at the bolts I think it'll have to be a 1/4 inch drive. Saw a set of deep bi-hex sockets but £110 was a bit more than I planned on spending!!!!!!!

any tips for curing leaking rocker covers?

Replacing the cork gaskets with the later LR rubber ones works for me. Sorry I replaced my bolts with socket caps.

the socket you need is a 1/4" drive 8mm multi point socket.
I use rubber gaskets and some silicon above and below them as well as I got fed up with the same problem.

They also fell into the :spit::spit: category then Pete?

The only bit I'm not too sure about are the cap head screws for the manifold. They look pretty, but they aren't as convenient as ordinary hex headed bolts tbh. It's easy to get a ring spanner on to tweak the original hex bolts, but that isn't on with these newfangled things. Still, don't they look pretty?

Nah I did try some socket caps on the manifolds, Joo reckoned they might work - but they were actually even harder to get at than the hex heads...

I was joking about the 16pt rocker bolts being alike to your "100A fuse :spit:" quotation

Rubber gaskets on order and found a set of deep 1/4 drive bi-hex sockets for £20 so should be sorted.

Thanks

A bit late, but you can buy the correct socket individually from Halfords for 3 quid, you need the long reach one BTW

I had to trim the return lip off my rubber gaskets to get them to fit. Once fitted though (with silicon) they are totally oil tight.

Started the task of replacing the rocker cover gaskets yesterday. Hadn't appreciated how much stuff would need disconnecting just to get the covers off.

On my serpentine engine I've had to undo
The fuel pipes from the rail
The water feed to the heater
crank breather pipes
plenum cover
spark plug leads

Also the dipstick pipe was connected to the rh rocker cover and I douln't get access to the screw that was clamping it on so in trying to bend the clam sufficiciently to slide it over the top of the pipe I've kinked the pipe slightly.

I can still insert the dipstick but was wondering how easy it is to fit a new one.

Any tips when putting this back together? I've got the rubber gaskets and silicon sealent ready.

You don't need silicone sealant, they are designed to be fitted dry.

I used silicon on mine, when fitted dry they started to leak after a while, with a bit of sealant have had no problems at all.
