Ok, So after tooling around on here for a couple days I cannot find an answer to my ? Hopefully someone on here can help me out.
I have 2 Cylinder heads lying around and I want to use one for a fresh new build. Problem is that one of the heads had a t-belt break, the other I hydro-locked under boost.
So, on the first head this is what happened. I broke a t-belt, and a valve busted off in my piston. The valve smacked around in there and there are a couple dings in the combustion chamber. None of the damage is near the valve seats, and my impression is that the Valve should still be able to close no prob. Actually the only damage is in the curve of the chamber, not on any valve or the core for the spark plug. So, since there are imperfections in the chamber is this head bad? Are there any options?
Cylinder head #2. I had done a build in '06, and less then 3k miles later I hit a wicked storm and sucked up water under boost. I blew rod #1 and rod Number 3 was bent like a J. I was soooo pissed, like $2500 down the drain. Anyways, I had a 5-angle job and the head decked during the course of the build. Now there is a straight line, that runs parallel to the lines on the head from the machine work. It is not a wiggly line/crack, but you can feel it with your fingernail. It sorta looks like the line was already there and I can see it now because there is dirt in it. The head is flat, no warping or other damage. All valves open/close without any issues. But the line that runs from the #3 combustion chamber to the side of the head has caused me to toss it to the side until this point. Is this head any good? Can I use this one? Do I have any options? Can I get it decked again to take the line out? It isn't measurable, and from the side of the head you cant even see the blemish. You can only see it if you are starring at the combustion chamber.... Should I even worry about it? It will be on a fully built bottom end. I just wrapped that up last night, thought I would ask around about my heads before I buy another one(already have 4, 2 just described/2 in action).
On a side note, I am a true DSM guy. I have 5 blocks/4heads, Ive earned my stripes if you catch my drift.....
I am only going to run around 12-15 PSI nothing too crazy. Its my DD, she is just starting to burn a little blue during shifts and to reduce down time I have been building her a new motor. The rear main was leaking a bit as well as a spot on the bedplate I must've missed with the anaerobic sealant too-so i decided to swap motors and throw this one on the stand for some lovin'
Any input would be appreciated.
Thanx-Justin
