My 3rd gen was belching coolant, found out it was a blown o ring, I had exhaust gasses coming from the filler neck.

I have the engine apart and the o rings look fine. I cleaned up the rotor housings and see no warping. Unfortunatly i only have a .005" feeler gauge as my smallest. I'm going to check with a smaller one when i get one. I thought the o ring was the only place for the gasses to escape to, what else could be wrong?

 

was this a recent rebuild?
are any of the coolant seal lands broken?
pics?

 

this was your rebuild. J_J's old car. I've been in contact with you before. The seals were beautiful with no breaks. The lands look fine. I'm wondering if there was enough warpage that it slipped past when things got warm.

The symptoms werent as bad if i kept the temperature down to 85c, but if they were at 95c the puking would be really bad and there were definate HC's coming from the filler neck. The system would also pressurize within 20 seconds on a cold morning.

I never got the coolant cloud. The cooling system held pressure durring tests, so it seems it only showed up when warm.

I did notice there was dirt buildup in some of the passages, I'm still trying to figure out how the dirt got in there since the seals look good. Also It looks like you got a little silicone happy. Not trying to knock your work, just letting you know to tone it down a bit with the silicone

I pulled all the seals out and didn't take pictures of them inside the housings. I still havent gotten another feeler gauge to actually check the warpage.

I've cleaned em up and dont see any cracks, is there any particular failure point that i should take a closer look?

 

oh that one.

it didn't do any of this until it was overheated the first time, huh?

as far as any "dirt" in the housings go, all i can say is they weren't there when i put the motor together. unforunately, i'm not responsible for what people do to their cars when they leave here.

like complaining about a vibration above 5500rpm at full boost on a 2-day old motor...

 

well i got new housings coming in the mail and im going to get the irons lapped. Should be **** when its done. Thanks for your help.

 

My 1st rebuild had exhaust coming out the coolant too. I read somewhere that it could have been due to me using vasoline instead of assembly fluid.

 

it held up fine until it was overheated...

rotor housing warpage is the first place i'd look.

 

Check around the spark plug hole especially in the threads to make sure their not cracked...

 

230 is debatable if it is overheating. I guess i just have bad luck, but then again i was rolling around for a week without a temp gauge and bigger radiator, so who knows how hot it got in this summer heat. I've got a koyo, a temp gauge, and the fan mod now, my power fc datalogit software should be coming in soon so i can control the fan temp. I'm also considering the new autometer gauges with warning system. Either way, it is getting fixed, just sold my turbo Integra and have some extra cash to get things done.

The thing has a bit of frame damage that im going to get fixed proper too. It has a 1/4 inch of setback of the wheebase on the right side. I know a guy that can get this car really nice.

 

it has quite a bit of frame damage... i think jj neglected to tell people that when he was selling it.

 

Pitting on the coolant seal wall between the groove and coolant passage will cause this problem also. Take some 400 grit sand paper and lightly sand the plate surface around the water seal grooves. The pitting will look like little dirty specs. If you see any the plates will definetly need lapping. Measure the plate thickness before and after lapping. You don't want your plates to be to thin or it makes setting the end shaft play real difficult as you won't have a spacer the correct thickness without getting one machined.

 

the only damage to the rails that i can see is some splitting of the layers on the bottom. hopefully that can be corrected.
