Well I'm seeing some oil leak underneath the car near the oil pan and TC after HS install ( 1 by 1 method). DOes this mean my headgasket is leaking? ANyone else seeing this? Compresstion test shows 175 across and I'm not seeing any white smoke. Any help would be appreciated.

Pictures below. If my coolant have oil does this mean that my Head gasket is shot even though compression is still good. Will reloosening the stud and tightening it help?

Thanks.

Any help or suggestions??

 

that looks serious. try to look at your radiator coolant . check if you see oil in them. and run your engine with radiator cap off(do this when engine is cold) and see if you see tiny bubles coming up. if you see it, chances are you have blown your head gasket.

 

Didn't check my coolant overflow bottle until today and did saw some oil like substance but I put redline water wetter in there on Saturday and from what I read water wetter will cause this.

Start engine with radiator cap off? Wouldn't the pressure from starting cause the coolant to squirt out??

Thanks.

 

that leak looks more likely to be the cam cover gasket then a head gasket.

If you want to verify the head stud install just take the cam cover off and go over them all 1 more time at 85 ft. lbs. in proper order.

 

Thanks a lot. Do you think I need to cycle torque each nut 5x, loosening the nut and retighten it back?

 

mine is leaking too after cams/HS. I did not have the right type of silicone to seal around the area where the roller bearings are. Any one knows what kind of silicone the OEM silicone seal is?

 

No, at this point you've ran the car for a few miles so they have been heat cycled enough that your final torque should do it.

I reused my studs when I did my motor and never bothered to check them because they had been heat cycled. Plus at 85 lb. ft. they will definitely reach enough stretch.

Head studs still have a stretch to them it is just a very small amount.

 

Not sure exactly where you mean by roller bearings but the oem valve cover gasket is rubber. I did not put any grey rtv gasket maker on the cam sensor side of the valve cover.

 

Thanks a lot. Driving to a friend's house tomorrow and will look at it. Will try to let the car cool down but I might be checking it with the engine warm so I hope it won't be a problem. I need to get this thing straighten out before ordering an alky kit

 

More that likely, it is your valve cover, add some gasket sealer along the back, especially where the cam brigde is at, its probably leaking from there and running down your block to the oil pan.
Make sure you clean the engine with degreaser before you add the sealant so you can tell if the leak stopped.

 

I've seen this on several Evos with and without head studs installed, including my own... I've yet to tear mine down due to me not seeing mixed fluids, or oil usage between oil changes.

I did have one customer who we went with ARP torque specs have oil in his coolant. He could not afford another tear down (one head gasket already replaced), so I reluctantly step torqued his head studs down to 85ftlbs. He had his fluids flushed and has not had another problem. That was quite some time ago... Let me restate that this is NOT the proper thing to do if you believe your head gasket is bad. However, it did work for this person.

As to the Evos having this oil seepage issue under the intake manifold, I can't help but think there is something else amiss other than head seal. Too many have had this issue (granted the issue is sleight for some compared to others) without losing compression, or mixing any fluids for me not to consider another cause.

 

I would never recommend the 1x1 method for doing headstuds. Always take the head off and do it right. Remember you are breaking a seal when you do this, so I would take the head off.

Just my 2c, and a lot of people will disagree with me here. Take it for what its worth.

 

I agree it is not the best way but you are not really breaking a seal.
The head gasket is designed to handle that minor change in the way they used viton ribs for sealing.

For the person that asked, buy Grey RTV (Permatex). You can get it just about everywhere.

 

Thanks all. Head gasket is not what I wanted to hear It's going to suck if the HG is bad.

Zeus,

If you can explain your step torque process that would be appreciated.
