I'm Awesome
I got a question for all of you out there... what are some signs of a head with a crack in it or maybe burnt valve, bent valve, too tight, too loose. I ask because I see alot of ppl talk about tbi heads cracking and such, and can be missed by the eye and such. I don't have collant lose or oil in the rad or anything. It kinda scares me though wondering lol.
I get a miss or pop out the ps exhaust, I got duals so I know it's that side ONLY, ds is fine. It's done it since the motor has been put back in, runs and drive fine, just has a cold start miss and pop and warm too I think still does it. I'm thinking of hopeing maybe wires? I got new dist. completely new one, new coil, they are accel wires and new plugs, new motor, well rebuilt and the valves got cleaned up with a wire brush on a drill and some valve grind compound put on them and spun in the drill, my old man did it, he's done it that way fr years. Is there a for sure way to know if it's valve? Like leakdown or compression test? I don't have a cylinder leak down tester but I do have a compression gauge. I also plan to do a running valve adjustment on it. I've had it in the truck for about a year and half now, and only drove it for less then a year, probably not even 500 miles on it.
I'm really hoping it's not valve or head related because if so it's gotta come apart and it'll be parked for awhile and not on the road or put together forever cuz of my tight budget.
I'm gonna try the valve adjustment and yank some wires off another 305 or 350 motor and try them. I can yank em off my brother in laws monte carlo(my old one) since it's here at my place and I'm working on it for him. I guess afterwards maybe do a compression test.
The valves were spotless though, but I guess anything can happen. it's a stock replacement flat tappet cam too from northern. Brand new lifters as well as everything else in side minus rods, pistons and crank.
New 02 as well and has headers, shorties that do not leak anywhere, AIR pump and lines have been removed and cats were gone before I got it.
Every other motor I built and did heads the same way and reused them never had this happen, but this is my first computer controlled build the rest were all carbd motors and still run great.
