What the h did we do wrong?

Post by Datsun AshLee » Sat Jun 23, 2018 2:18 am

Hi everyone,ok..We put the new head gasket on and put everything back together. I started putting the anti freeze/water in and we heard the liquid flow in and then it started to sound like it was leaking out somewhere, looked under the car and nothing, I couldn't find water anywhere, so my brother checked the oil dip stick and the oil looked clear like water but still felt like oil and it was above the normal fill level. I'm assuming that the water went into the block. Does anyone have any idea of what we did wrong?

I assume you poured the coolant into the radiator???
Somewhere somehow you have a break through between the oil and water circuits :roll:
The head will probably need to come off again to determine what is what!

Just as a guess I would suspect the head gasket is backwards/upside down.

Remote possibility is something foreign stuck to the head surface as you put it in place.

A friend of mine and I did head gaskets on a V8 Buick twenty years ago. I did the passenger side and he did the driver's. He gets in the car after we're done and cranks it over while I watch the engine compartment. It immediately begins pumping coolant out of the driver's side of the block/head interface.
Head gasket on backwards/upside-down.
Good times.

Don't know about an R, but I don't think you can install a U20 gasket upside down.

The motor is a 70 1600 and the gasket we used had a bead of orange stuff on one side so we put the gasket on with the orange side down on the block, I scraped the block and head with a plastic razor blade before installing the gasket and we didn't use any kind of gasket sealer. Was this correct?

You can't install a R gasket upside down either... pushrods anyone?

At this point, we're assuming that the head gasket was the issue or the only issue. Can you tell us more about what was done?

I was looking at my old head (67) and noticed that there is a head bolt that attaches the rocker assembly but there isn't on 70 head, it's just all studs, is it supposed to be like that?
We torqued the head bolts down to 50 lbs in the order of what the service book said, and then the push rods went in, in the order of which we took them out, put the rocker assembly on and adjusted the valves. . Is there anything else I need to tell you? I can't really think of anything more.

There are logical ways to troubleshoot this.

The rocker bolts/studs are not part of your issue. Yes the early heads had bolts. later had studs. They are not related to a coolant leak.

Here is a really simple reality check:

Drain the oil. Leave the plug out.
Remove the thermostat housing and thermostat.
Put a garden hose in the thermostat opening on the head.turn on the hose and fill up the head.

If water comes out the oil plug, you have a broken block, a broken head or a major head gasket issue.

If water dumps out somewhere else, find out why. Best, jt

Curious if you did do an oil change after the new head gasket installation, if not the water you see in the oil could be from doing the head removal. If you did do an oil change and water is draining thru to the crankcase, I would drain the oil pan then remove pan to see where the water is leaking from. It could be a crack from freeze damage or just an SAE threaded stud or bolt threaded into a Metric hole that is tapped into the block and hasn't sealed, for example one of the timing cover bolts. You mention early and late model engines so this could easily happen. Just some thoughts that might be helpful..Bill

If, when you pour water into the fill, you can hear water running into the pan (or somewhere), it's not an sae vs metric thread difference and there's no simple "oh, you forgot such and such" answer.
You have a serious issue and will need to determine, by observation, what and where that massive leak is.
Jim (JT) have you the best advice.
