I started another thread with the same name about 3 years ago when I was rebuilding my engine. What I thought was an SER Spec V engine turned out to be an Altima 2.5. I sweat bullets making that engine fit back in the little car. The balancer still rubs the passenger side at times as it is so close. I rigged the transmission mount beyond belief but so far it is holding well.
Now for my next problem. There is a noise coming from the head, and I feel the head will need to be replaced. When I tore the engine down, it was just at the point of the rod bearings locking to the crank. Some metal had already melted and stuck to the crank and cams but not very much. I hoped a good polishing would solve the problem but it didn't. Polishing the cam journals and seats, causes the engine to have lower oil pressure. It still holds pressure enough that the engine doesn't mess up but it is low when it is warmed up fully.
I feel it is time to replace that head with cams and the works, or just drop another Altima engine in there. In looking, I see a head will cost more than a used engine unless I can keep searching and find one of a lesser price. My problem is I can't find a 2008 Altima JDM engine. Any suggestions?
