Again, 'WHAT' head gasket did you use. Yes I know that you got it from Repco, but what was the application that was marked on the packet?

Did it say Datsun A10, or Datsun 1000 & 1200?
If you are using a front distributor engine that is essentially stock, then that is what you need to see on the gasket package.

the third cylinder wasnt doing anything so i had another engine there and decided to change the head. then realised i had put later model head on it. but i have drilled hole and oil is comming through so car is running all good.

What exactly is the story with this engine? Did you blow a head gasket, and changed heads at the same time? Thats obviously not the head that was on it, coz you said it didn't have a hole.

We run it without the cover on, and not a drop of oil was to be seen. Is it the A-series push-rods that have the hole for the oil to travel up? cant remember.

Pretty sure oil travels up past the T-bolt, coz it's skinnier, and up into the rocker assembly....

Or straight from the block up into the head via that little hole your gonna drill....

been a while since i worked on A-series. Have you got the head off? I can pop round have a look if you like...on the weekend

i think i need to try that whole starting it up without cover on and have a closer look

If this can help :::

HEAD VIEW

does anybody have a picture that would show were the oil should be comming from there are lots of little hole across top op rocker but it seems more to be comming out of the two bolt looking things that are next to the head bolt. excuse my lack of not technical language

any head will click after u have taken it off.

check (by doin what whitesedan said) that u ahve oil up there now and then if u do take it for a good spin around the block.

if ticking persists conmsult your doctor

Start her up (not for very long) without the valve cover on, you should see oil come out of the rockers.

yer still got it had brake probs so didnt sell as it was ####ed. got them fixed and tried to change head now running into more problems. hopefully i can sort it out. dont even know if i solved the oil problem

Cool you didnt sell my old coupe!! Hows it going? More head problems?
