i just discovered that i have an intake leak.. me and my friend just found it out. not all 4g93 IM is the same.
i got the other version of it not sure which one though but its the one that gonna give u an intake leak.
he suggested that i need a thicker gasket made with metal and bigger hole. (60mm)
so what are the specs of the 4g94 intake gasket?


thnx guys.

 

Uhhh what? I've had 3 4G93 IMs and they were all the same except for the vacuum ports / outlets on it.

 

mines different than Rhyzins..
but anyways how can fix the freakin leak?

 

Well what TB are you using? Get the gasket for that TB (if you're running a 60 mm TB as it sounds like you are, get one of those) ....

That is, if you're sure it's leaking from the intake manifold and the TB.

 

im using the stock tb..
maybe i need a new gasket?

 

I guess my first question is, are you sure it's leaking from the intake manifold? How are you so certain?

 

its between the IM and TB. (where it connects)
Rhyzin's the one who found about it.

EDIT: he used the PB blaster technique. also when he put his finger at the IM, TB connection, the vacuum sound lessens..

 

Hmmm... I dont think the Lancer gasket was any smaller than the Mirage. But who knows. I'm all for the cheap / free fixes first. I'm sure you've tried bolting it down pretty good, esp. the lower bolts that are awkward to reach, and the gasket is in good condition?

Outside of that, get a new gasket. They should be about 3 bucks and that would eliminate one potential problem.

 

thats what im thinkin that might fix it..
btw the leak is at the top right side of the connection. (top right bolt, facing the firewall)
imma call mitsu tom after work.

also thnx for helping me man.

 

Throttle body gaskets are not meant to be re-used on the 4G9x engines. Also make sure that you install the gasket the right way. It has to be oriented a specific way. See the diagram.

 

i installed it the right way.. i guess i just need a new gasket..
if that didnt work, any ways to fix it?

 

About the manifold being different. could it be a 4g15 sohc intake manifold i got the wrong one at first but got that fixed. Here check this out and see if it looks like my old 4g15 intake https://www.evolutionm.net/forums/la...upgrade-2.html Hope that helps

 

EDIT: imma check it tom.. maybe were the same.

EDIT: its not.. i have a g93.
