| Help! low oil pressure on fresh motor |
| By Matt - 05/21/2002 7:44:12 PM; IP 12.152.199.3 |
I just finished going thru my 428 for the second time, it runs good, but the oil pressure at idle is 20 psi, it comes up with the RPM's but I'm still concerned.
I bought the longblock 2 years ago, it's a C6ME ('66 police Interceptor). I took the longblock apart, added CJ heads, etc. The old cam I pulled out was hydraulic, so common sense told me to put in a new hydraulic. After the engine was finished it ran good, except the lifters weren't getting oil. After much frustration, pulled the motor back apart to discover that the oil passages that run vertically to the lifter gallies had been blocked with short pieces of rod. The machine shop drilled them out, they appeared to be about 3/8-1/2" in diameterThe machine shop told me that I shouldn't have any more oiling problems. I put the engine back together using a Melling high volume oil pump, Rhodes lifters, new bearings (clearance 0.0015). I also put oil restrictors under the rocker shafts (0.092 I think, whatever the book said). I also had the machine shop put in screw in galley plugs. I started the engine tonight, 20 psi oil pressure. I took off a valve cover, the top side seems to be getting oil O.K. Any ideas? When they took out the plugs in the galleys, are the passages too big now? (I had 45 psi the first time around). Any advice is greatly appreciated.
Thanks,
Matt |
