I dont think its the head that was shaved wrong its stamped on both sides with EL VIUDO and some numbers on it and the guy i bought the motor from had it running fine, am lost here am gonna take it to the machine shop to see if they can find a crack anywhere and yes the leak is coming from the two exhaust ports 3 and 4 am thinking maybe the valves are barely bent were its not even noticeableToyota1515 wrote:So is leaking inside the combustion chamber?
I got a experience before with a wrongly ported head that the valve spring pressure broke into the intake port with a tiny crack, u can check on that as well as in the exhaust side, some think anyone can port a head but sometimes almost 80% of those are dead wrong LOL

Re: Head leaking bad!
Bent valves shouldnt introduce oil. I said that before I knew what was leaking.
I had the BRD rocker collars on before and they cracked one of my valve guide towers off. I guess I didnt give enough play and they didnt come with instructions. Maybe yours are slightly cracked.

Is not how it was shaved, it how it was ported if the port walls are to thin time and heat cycles and vibration with crack the port walls right where the valve spring is applying pressure on the top of the port, i found that many times bro!

Re: Head leaking bad!
At the valve guide you need to check if the valve has play, and don't use the valve seals that come in the kit the ones that look like a piece of rubber hose with two wires around it

Re: Head leaking bad!
Got the head back from the shop everything is perfect on the head so took a better look at the pistons and found that the piston rings are bad theres a tiny little crack thats bringing the oil up.... So i decided to bore the block put bigger pistons, rods, and a cam on it might as well take care of that issue once and for all
