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

No leaks yet,

"You don't need to rtv that"

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

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.

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.

cvbikeguy · 01-13-2010, 02:49 AM

Hanging out with the plugs in the gally? What does that mean?

cre · 01-13-2010, 02:50 AM

Make sure the plug galley isn't full of coolant dufus.

cvbikeguy · 01-13-2010, 03:55 AM

lol. i only got one of the studs through the egr valve on accident. didnt notice and proceded to put the nuts on. pinched the valve and the nut. cant get it off. F me

Coolant on outside - OK

Coolant on inside - BAD

Check for collant in OIL and in vacumm hoses. Vacumm can suck coolant into engine. If car is running fine it will burn off eventuallly but will run rough till it does.

Pull plugs and crank engine to purge any in cylinders and check plug tips for coolant.

Not sure what you mean on the valve nut thing?
