New engine runs....BUT
Hey all:
I finally go the new small block running.. The difference is that it is lower compression and the cam is bigger than the last motor. I did the cam break in, then took it for a ride. Here's what turned up:
First off, the coil connector broke, so I had to run two pin connectors in place of it. The car would stall out after going about a mileor so. I think the bumps rattled the coil connector that I made, and therefore, I just pushed them back in and the car seemed to run better. I hope when i get the new connector, it will not stall and maybe it'll idle better. I reset the idle adjuster and sometimes it stayed at 1,500rpm, other times it droppped to 750 rpm and wanted to stall when it was at the same adjustment. I had to double foot the brake and throttle to get it inot gear without stalling most times. ideas?
Two: The oil dipstick got kinda chwed up and bent by the crank. I don't recall putting in or taking out a lower dipstick tube, I heard that on earlier models, Gm used a lower dipstick tube. I have a pre-97 (probably late 70's or early 80's passener side dipstick block. ideas?
Three: (this might be the worst)
The oil pressure was at 30 on the cam break-in. But, once i restarted the motor, the pressure with 10w-30 was only at about 8-10lbs, on idle. But that was a rough idle that was almost stalling. I have a electronic stock gauge. I want to change the sender and get a mechanical gauge. However, it did jump up to 30 lbs whenever i brought it over 2,000 rpms. I know it never went that low in the past, I don't know if its just the sender or if I have a problem. The oil pump only had about 1,000 miles on it, so i took it apart, and inspected it....that's why I re-used it in the new motor. It was an expensive one, and it worked fine when the oil motor quit, (even after it quit).
Anyway, I will get the coil connector, but I hope that solves the rough idle. I am not too concerned about the dipstick now, caue i don't need to run one. The oil pressure however concerns me, and it seemed as if the oil wasn't really flowing into the rockers, that well, but it wasn't at a high rpm when i looked and I think the lifters were filled with oil, cause the motor sounds good. COMMENTS?
oh btw, the pass side rockers were noisy, turns out they were hitting the valve cover.....fixed that.
