I reciently completed a mild build on my gsr, including set of pr3 pistons, new rings, 97 spec ITR cams, IM, TB, full exhaust. I got everything installed at Honda Dealer (where i work), and the head i sent off to be cleaned and just a normal valve job on. My problem is that i am loosing oil very badly, about 2qts in 1500 miles. My question is where is it going?? I completed a comp test and had 185-190 all across the board. When i had my head cleaned and valve job i got new valve seals installed. The shop is pretty good i guess they do most of our work at Honda. But do u think It's possible that they could have messed up the valve work? just give me some ideas i hate to tear down again if i don't have to.
thanks guys/gals

 

You said you put in new pistons/rings right?

Did you seal the rings/break it in properly?

 

yeah 1000mile break in period

piston and rings installed by shop foreman 30years experiance

2nd set of rings in car, me and the shop foreman thought maybe that was the prob the 1st rebuild so he installed new piston rings and re-honeds the cylinders

Yeah but did you break it in properly. Driving it soft is not breaking it in. How exactly did you go about it?

You should've went straight to a tuner to dyno or at least street tune the A/F

 

had a phearable ecu with basemap for car.

 

Does it smoke when you drive or idle? Try to check valve seals, sometimes the machine shop put the intake valve seals on the exhaust and vice versa can cause loss of oil.

 

smokes all the time... has small lobe at idle too. not like iacv lobe but small almost un-noticable.

 

yeah when I got my head back from this machine shop they put the intake valve seals on the exhaust side and mixed them all up. Worst was some were no even on all the way on the guide.

I cannot believe these guys do this for a living...some people arejust wastes of life good thing neither of us are them right?

Pull the head and do the valve seals yourself. its really easy.

 

is that how urs ran?? just wondering, i was going to take the head off tonite to check

You know what the problem is tho. Alot of shops and even honda technicians do not know this and spread the "be easy on the gas" stuff onto the consumers who just take their word for it.

Yup, and I'm sure the OP thinks his basemap was good enough lol

which we all know (well, informed people atleast), isnt the case.

 

so you are telling me that my basemap could have caused my rings not to set correctly even after i hooked up my a/f and everything seemed normal(from narrowband stand point).

ring seating is all about the breakin. The true way of making the rings seat is by beating the **** out of the motor while tuning it on a dyno or on the street. THEN you can do the 1000-1500 miles of easy driving if you want for your own reassurance.

and a narrowband 02 output will not tell you anything.

 

ok, so now ur saying basemap i washed my rings out? because of improper tuning... is that the final answer???

 

im not saying its a definite, but it is a possibility among other things.

the fact is that you did not break the motor in properly and you are still running a basemap. I'm willing to bet that your rings did not seat properly and the oil is seeping through the rings and getting burnt up in the combustion chamber. But the only way to tell if your rings arent sealing is to run a leakdown test.
