hello honda tech I really need some insight. I just recently had a b18b built and installed a gsr head on it(done by a professional well know shop). Well it came time to start the car and upon first crank up the car ran only on two cylinders. Well I installed new plug wires and a distributor coil plus adjusted the valve lash. Second attempt the car runs on 3 cylinders. After this I try I number of thing different injectors plugs plug wires different distributor distributor wiring. All to no avail The car has fire and spark. But no combustion. Everything inside the engine is new from rod bearings to new cams and all professionally put together. I’m just stuck I’ve invested 13k into this project and have a dead cylinder any insight would be appreciated.

 

Have you checked compression? Running on basemap? My LSVTEC would barely run at all on the basemap I had, tuning fixed that.

 

^^^ What he said, do a compression text ASAP.

 

Sadly I have zero compression on this cylinder my thought is pointing toward a valve issue and I don’t understand. this motor was brand new top to bottom and all I did was start it.

 

This is exactly why I build and tune my own setups. I’ve been screwed by “professionals” over and over again no matter how much $ I spent.

 

i has him to lock vtec and I’m hoping that my valve lash is off which is what the guy who built the motor seems to think and I agree. I’m building a z6 for my dd myself
