Possible Crack Or What....?Valve question too! FIXED!


Recommended Posts

Hi All,

I put the engine (EA81) in a week and a half ago, ...It seems to be running fine except for a slight knock over by the #1 and 3 cylinders,...It passed smog last Sat. NOW there is coolant on the ground and I cannot CANNOT find any hoses that are leaking. I think ONLY THINK, there may be a crack, but would that emit steam or if it was a hairline crack what would it do? I hope it isn't and am going to try to look more tonight. Like I said it runs fine but sometimes this small pudle shows up and the coolant comes down form the crossmember that holds the ngine in place.

 

Very perturbed about this, :-\ want to get this on the road!

 

how do I know if this is a solid or hydraulic lifter engine? I swapped valve covers a ways back and didn't notice any silver tags or such like that. I pulled the pushrods from another engine and they are all aluminum with steel tips. Know anything about that?

Hopefully this is just due to a loose hose clamp that is leaking under pressure. I would top off the coolant level and check for a leak after the engine is hot. You may have to leave it running to spot the leak.

Yeh I had it running hot last night in the driveway and didn't get anything wrong, drove over to a friends house and he was home and when I pulled rom his driveway I saw the coolant, took it abak home and saw more coolant, let it runand wiped up the crossmember and drove it around somemore and then pulle to the other side of tthe driveway and no coolant at all! Really wierd. I am just trying to consider if the block is CRACKED and it is leaking from that area. I did notice coolant up higher on the engine below the thermostat , but the thermo wasn't leaking at all and I am wondering if that is an area of cracking concrn or not. Seems I have the time to write aobut this at work, but by the time I get off work and get home it is getting dark and cannot dig into as much!

 

Oh well!:confused:

It is far more likely that the leak is from a loose/leaking hose or from a leaking gasket than it would be from a cracked block. And it seems that any leak ends up dripping from the crossmember.

 

Good luck.

look for what appears to be a 14mm bolt head on the bottom of the head. each head has one, the one on the passenger side will be toward the front, the one on the driver side toward the back, mirror opposite.

 

my car made a drip and i checked the plug and found it missing? dont ask me how the car held water but i replaed it promptly

 

also check out the hose between the intake and the block as it could be leaking and dribbling down the front or back of the motor

Wow! didn't realize about those two on the heads. Fortunately the leak is not in those areas. I thought it was either the heater hoses or the thermostat, something in the back which keeps dribbling down to the crossmember, BUT will still look, thanks for the advice,

 

BTW how do I know if this is a solid or hydraulic lifter engine? I swapped valve covers a ways back and didn't notice any silver tags or such like that. I pulled the pushrods from another engine and they are all aluminum with steel tips. Know anything about that?

Unfortunately I do not have the orig. I bought a used jap engine from an outfit in TX. Is there a way to look up the engine number and see? I know it has pushrods and I think the other way to tell is to look down where they come out.....

Adjusted the valves last night and drove it around. Exhaust valve #3 was opened up too big. The adjustment seemed to quiet the car down (but still in my mind there is a clickety clack sound at around 2500 rpm or so, just guessing rpm as I have no tach.)

 

As far as the start of this thread stating cracked block, that is wrong, I have found the leak just under the intake manifold from a little hose going into the engine. When it leaks it spread over the whole of the engine and actually creates puddles in various lower spots of the motor,..... so that was hard to trace, but I know now that hose is the culprit.

 

Thanks again guys!

 

Rich:D
