EDIT: I am sorry... I re-read the thread and this was a rebuild.... I'm getting confused from one member to the next this past month. My apologies.

Here's some excellent information on breaking it all in: http://www.supramania.com/forums/showthread.php?t=48993

Sorry Joe, I'm an ass.

hahaha yup yup rebuild. anyways so i was so frustrated with the car. and its numerous amounts of leaks.....

so i took it all apart. hahaha in one night. i start worl in 5.3 hours. grrrr i better hurry

Where in the engine should I or should not use rtv suff. (Gasket goop)

cvbikeguy · 01-12-2010, 02:00 AM

im still alive.....

car isnt.

so i have everything fine and perfect.....

except a leak underneath the intake runner (that tiny nipple i was trying to find before. but it actually doesnt look like its coming from the hose. looks like coolant is leaking from where the intake runner and the engine head meet..... im so lost. this will be the 4 time taking everything apart. any ideas?

thanks

The coolant channel passes through the runner's flange and into the head. If the gasket is damaged or poorly sealing it will leak.

Yup - true as rain. That magic nipple under the intake runner feeds right through to the head and if the gasket is not right - will leak. I RTV every place where coolant can leak. .

Also don't forget about the coolant bypass that goes up to the throttle body as well

RTV the Intake runner on both sides where the collant passes through, Rtv all coolant hoses

No leaks yet,

"You don't need to rtv that"

Last time I listen to a guy with an evo also...

Grr

Excellent! Thanks for the pics Joe!

One thing to note is that if the gasket has a viton coating for that passage you need to be very careful about any sealants you might want to use on them... most contain enough trace solvents to cause the viton to bubble or ripple and may actually cause a worse leak than allowing the viton to do its job. If there is no sealant present, then YES, a thin coat of RTV is the way to go. I've had both types of gaskets in the past and neither leaked... never tried one with no sealant.

ahouls i be worried about the coolant getting in places it shouldnt since it leaked?

Well, as long as it isn't pooling up anywhere you should be alright. Make sure it's hanging out with the spark plugs in the galley.
