I did a d16z6 IM with an LS TB swap on a d16y7 engine for my crx.......... The crx runned great with the stock manifold before the swap....

The car bogs some times and I there is a vacuum problem since it idles around 2000 rpms. I threw water with soap into the manifold where the IM gasket is, and the car bogs more....

some info:

1) I re-tightened the IM screws, but its the same...

2) Throttle body is all the way closed

3) idle screw is stuck

4) used a new crx 1.5L intake manifold gasket

5) there is a platform on the bottom of the intake manifold that matched the d16a6 manifold but the bolts dont match the d16z6 manifold


any recommendations ?

just wondering, did you tighten the intake manifold per "the pattern"? kinda like the head gasket, where you start in the middle and work your way to the outside with the proper amount of torque in "steps"........just an idea

also, did you prepare (clean real good) the surface for the new gasket?

good luck.........

 

I did start from the middle,

I also cleaned and removed the old im gasket

 

check your tps sensor

 

I just bought an oem IM gasket at my local honda parts store....

well see...

 

I still don't get why people throw water and soap on the IM? ...also check your map & TPS

The same reason they say runned and not ran lol. It's just a common misconception. You use soapy water to find air pressing out (for example, a tire), and on an engine, you use carb cleaner or the like to check for vacuum leaks. The idea being that if you hit a spot that is leaking, it will rev a little higher as it sucks the highly flammable spray into the intake. Now, you have to use common sense as spraying things that are caustic on rubber will leave you with more leaks than when you started.

My opinion is you have an intake gasket leak. You may have gouged the surface, and there are two way to fix it. The right way: Take the head off, take it apart, and have all the mating surface machined. The wrong way (See bandaid fix): Use RTV sealant like any number of shady back yard know it all rednecks that like to make things worse than they were when they started working in it.

Just my two cents worth of soapbox preaching...

 

Well it turn out to be the IM gasket of course.....

I removed the aftermarket one, cleaned everything, and used the OEM IM gasket..... no more leaks/coolant burns and car runs fine now....

I am not going to use any aftermarket gasket from now on .... my car was running like shitt and smoking coolan too.. =O


I learned the hard way
