here is the scoop, i put a ported and polished head on my D16Y8 SOHC engine. when i tried to start the car, it would not start, it would only turn over. I tried everything in the book to make sure i was puting it on correctly. finally after 2 weeks of trying i decided to put the original head back on. when i tried to start my car the car started no problems at all. now i have put in over $200 into the ported head, just to have to put the original back on. and the shop that i got the ported head from is not wanting to compensate me for the costs i have put out, but they are willing to give me back my money. the shop is telling me that the head is in perfect running condition and that it is operater error that it doesn't work. what i would like to know is if you guys think the head is bad? And why would my original work if it was operater error? thanks for your help guys, gloria

 

What's wrong with the head?

 

with the ported head, who knows. i just know that i did everything the same for both heads and the ported one would not start for nothing, and the original fired right up.

Did you check the compresion?

 

Gloria, I have to be honest I agree with the shop, there is nothing about porting a head that will cause a motor not to start---even if the valve job didn't seal it would still run, just not very well. I could be completly wrong since I am not looking at the head myself but I couldn't think of anything that would cause this without you doing something wrong, good luck,and IM if I can assist you in any way.

 

yes the compression in this head was in the 60s and 70s with the cam gear at 0. with the cam gear advanced to 10 degrees it went up to the 90s and 115, but that was the best i got out of this head.

 

were the valves lash specs ok?....to cause that low of compression #'s

 

they told me that the valves were i good condition, but who knows, i believe i got the short end of the stick in this deal.

 

Compression was down in the 60 & 70's....could it be that cam/crank timing was THAT far off?

And advancing the cam 10* didn't cause piston-valve contact? From reading various threads, this seems like a dangerous amount to be running, if its even physically possible (but I could be wrong there).

Are these stock cams?

 

Shoot Gloria, you didnt tell me that you put the stock head on and it worked good. DAMN now what? is j&w not giving you the money or mashte ( spelling??) i agree that if the head is working properly then they wouldnt want to reimburse you for the gaskets and stuff, but i saw that you had a post on a reground cam. could that have caused any of your problems? i know from what i have read that reground cams are not as reliable as billet type. you head has a port/polish & 3 angle valve job and thats it right? damn girl, i dont know whats goin on. i would just give back the head, get your money back and just call it a bad experience learned.
maybe never go to j&w again, and maybe dont trust the other guy either, ive seen a lot of his things go bad.
im sorry to hear about that though

 

well i think it was a bad head. i along with leila (fmaxturbochic) worked on the car to try to get it started, and nothing happend. it did not work and the head would not hold compression. if she did everything to the new head that she did to the old head i dont see why it would not start.

I will totally agree with the latter. Fmaxturbochic and OrangeHonda had the head torqued and untorqued over and over again in sequence. I know I was there assisting them. I did not know that they tried to use the stock head again and start. Well then there is your answer the head is %&$%^& Trust us on this one!

 

gloria as I said in our PM find out where portflow or joe alleniz is from you call them set something up to either drop the head off or ship it, as I said these are names we can trust, if you want you can even ship it to me and I will take a look at it. I am not a mechanic, but I know from what you have told me the motor did have compression-enough to start it. A engine doesn't know how much a bolt is torqued or in what order, so as long as it was tight enough to seal the gasket and hold compression it would be enough to start it. so I want to hear more about the reground cams did you re-install those with the stock head to?

 

The head didn't have compression to hold. I was talking to Gloria and trying to help her out, funny thing is, when putting on another head, it held compression and fired right up. I'm thinking the way it was milled or the head bolts not sealing the head to the block properly. Something was going on because compression was obviously leaking out.

The P/P head was screwed.

 

well see at first we were under the impression that the head was milled. and then she took it to some place and they wmeasured it and found that it in fact was not milled. and we used new bolts and it still didn't work.

Oh ya, she told me that.

That's some odd ****. Good thing her car is running now.

 

thanks to all you wonderful friends of mine for the excellent help! i in fact believe this head is definately screwed! but you guys are definately the BEST! thanks for everything, gloria
