Ok I am building up my GSR head and got all new valves i set the valves in and fill the combustion chambers full of b12 carb cleaner to see if they leak and they stay full but there is some leakage also the valve springs are not installed yet doI need to do this test with the valve springs and retainers in or could I do it on the weight of the valve itself?

 

Also these are the valves I purchased:

std size flat valves I should have to do anything to the seats since these are std size right?

Thanks

 

you can't just put valves in and go. need to do a valve job.

 

True, also need to install the springs and retainers

 

So I should have a valve job done even if there is no leakage?

also talk to the machine shop and they told me if they dont leak then the valve job isnt needed

 

Bump

 

I would do a valve job, it will cost more now but could end up saving you in the long run.

 

I get a lil bit of white/grey smoke at high rmp in vtec or on the freeway when im on it and let off to cruz I can smell smell smoke but cant really see any smoke... Could this possibly be fixed or affected one way or the other by doing a valve job..? B17 motor rebuilt at like 170k now with about 240k..I dont burn or go through oil and have no loss in power as far as I can tell but it just bugs me.. or could it just need to be tuned..? I had chrome put pn the ecu to eliminate all the sensors but just used a stock basemap since the car was fairly stock still at that point...
