TSX Intake Manifold DIY / Q & A

[Silver Bullet]

I got an air leak. I'm running the p2r im and tb gasket. I tightened the bolts down all the way and I have an air leak. Car sounds like turbo when I drive. -.-

Figure out where the leak is?

Get a mechanics stethoscope and figure out where the leak is.  That will help you determine where the problem is.  The purpose of a gasket is to prevent leaks.

Hey guys, I think I may have a problem. Before going to a mechanic maybe u guys can determine if I have an air leak or not. I took the gasket off and decided to just use the oem tb gasket and no Im gasket. When my car is in park, and I turn the steering wheel, it starts revving up but it doesn't look normal and the car sounds like its gonna stall.

I checked the vacuum hose and it's in all the way and I tightened everything. All hoses are in. Is this idling normal with the tsx Im?

[timot_one]

No.  You need to use an IM gasket too.  That's where your vacuum leak is coming from.

I thought the Im gasket wasn't required

[Silver Bullet]

Btw thanks for the quick response. I'm pretty frustrated over this. Seeing how everyone else didn't seem to have any issues.

I thought the Im gasket wasn't required

It's not required that you replace it.  You can re-use your stock IM gasket though.  Regardless, you need to use a gasket.

[Silver Bullet]

Ahhh I must have gotten it confused with the bracket -.- silly me. I'll find out and hopefully it will solve this. I appreciate all your help Tim. Thanks again!

[Silver Bullet]

I put the Im gasket but no luck. When I'm in park and I turn the steering wheel, the car starts revving/idling strangely

did you transfer that nipple from your stock IM to the tsx IM?

[CrackerTeg]

You could have a vacuum leak. You could still have leaks around the IM itself. Also, turning the wheel side to side puts a load on the engine so the idle changes to compensate. Did you check the mating surfaces to ensure they were straight? Maybe your stock gasket is blown. There's too many variables to pinpoint but the best thing to do is get a mechanic's stethoscope like Tim said and find the leak. One thing I need to ask, in what pattern did you bolt/torque the IM down? That may also be your culprit for an uneven seal.

[InFuMoUs]

Isn't there a hose that goes in the back of the manifold? Maybe you forgot to plug that back in.

Quick question - are the P2R and Hondata Gaskets used in combination (if wanted) or not?

I'm debating on whether to go with the Hondata Heatshield ($55) or OEM ($3) lol...

Wondering if the P2R and Hondata are used in conjunction?! Anyone?

[timot_one]

From what I recall, the Hondata gasket goes in between the head and the injector base and the P2R goes in between the injector base and IM.  I could have it backwards though.
