This is second engine in last 2 years which have water leak directly from engine block wall. Seems like out of nowhere. Under factory marks.

Something around ~500ml of coolant on 6 miles engine losing.



Have video too, don't know where to upload.

 

wow, thats crazy. I've never heard of anything like that before. I guess if my h starts doin that, I wont be shocked now

 

yea i have never seen anything do that before! Fill the cooling system and pressure test the system and watch to see if you actually have a crack in the engine block.

i dunno.... im thinking the headgasket

 

Take of the header and take look.

 

there is no frost plugs on the front or blockoffs going into the block in that area? I have never worked on an h22 so i don't know.

 

i have seen a few h motors leak there. we always just weld the hairline crack.

I'm not English speaking man, could you explain "hairline crack".

I'm shop owner, this is costumer car. Have some H series blocks lay around, that's not the problem, to change it.
We just did dyno tune, install intake and did some job to exhaust. Car finally start to run very well. Sad to see such things after successful tune. As it is not first time, would like to know, maybe this could be H series sickness/problem!

 

the hair line crack is a fine crack about the thickness of a hair. it is caused by poor casting when the block is made. after prolong heat and age the casting flaw becomes a crack.

 

Engine is from 1994 year 4 gen lude. Costumer install this engine by him self. As I understand this the donor car was not moving for about 3 years, maybe this long time standing could cause the block. Because we tune it at WOT for some hours.

I have some engines and there will be no any risk if he weld this hair line crack.

I don't have ac/dc welder only for stainless. So, the car owner will do the welding somewhere else. I recommend to drain the water, oil and carefully clean the crack. I will update this trouble next week after Easter.

Maybe you have some pics?
