Apollo tank; fitting into head leaking

[cab260175]

Hello

I have just placed a deposit on a Superlight. It is fitted with the Apollo oil/air seperator tank. The elbow from the small breather hose on the top of the tank going into the cam carrier/cylinder head appears to be loose. Is the hole in the cam carrier/cylinder head tapped (threaded) or does the elbow go through a plain hole with a nut inside and outside? I'm hoping it is the latter and the thread (if there is one) isn't stripped.

Does anyone have the fitting instructions with some pictures that they could scan and email?

Thanks in advance.

it is a nut on the otherside, most of them seem to leak!, some fit a non-return valve to stop it venting the tank with the engine off and draining into the sump

There is some useful info on Anguus's site along wiht tons of other 7 stuff at www.mycaterham.com/66828/67348.html

At least it's not a stripped thread. I'll try and do it when I pick it up.

I don't suppose you know if you need a new gasket to do the job....

Shouldn't have thought so, the cam cover gasket on a K is a rigid plastic sheet type that should be reuseable

Just a thought but if the nuts come off then where is it and has it done any damage to the cams?

Thanks again.

Can you recommend a good K series engine manual? I'm going to have to pick one up along with a build manual for the car.

I don't suppose that you have the torque for the cam cover bolts to hand before I have to go to Halfords for a quick look....?

Yep can cause damage!

Rover 214/216 covers the K series basics, IIRC Cam Cover bolts are 7lb/ft but just tight is a good level too

I don't think the nut has come off, the elbow would pull out of the cam carrier cover if it had. It is loose (1 mm or so of axial float) but has been that way since the car was bought from Caterham Midlands two years ago. The present owner said that it has always had a slight weep from the elbow since he bought it and it is a factory built car as well....

It takes about 15 mins to tighten up the elbow. They come loose on loads of cars. Just get to it, seal it and tighten it up. It will be fine, as long as the nut hasn't come off

Picked it up and I tightened the elbow/nut no problem. The hardest part was getting the plug lead on number 4 off.

Thanks
