| 390 Mach 1 problems |
| By Scott A. Ekleberry - 06/19/2004 1:43:23 PM; IP 24.209.97.157 |
Tossing this around on the various forums in a hope to get some help.
Finally got the 390 in the Mach and got it running. Trans. went out 5 minutes later (and the blasted thing has headers!). Even though we ran it for at least 20-25 minutes to break in the cam and engine it is still smoking like you know what. I'm positive all the pistons are in the right bores (he stamped them on top as to which bore they go in), I filed the rings as directed, made sure the rings were spaced opposite on the pistons (cast rings). This engine is balanced and it has new or reconditioned everything (all ARP bolts/studs and Fel-Pro gaskets, Clevite bearings, etc.). Only 2 places I can think the oil could come from are the rings or the valves at the top (new valves, rebushed guides, new seals, etc.). I put in a HV oil pump, could the oil be coming down the valves?? It does have a Performer RPM intake with C6AE-R heads and the corresponding correct Fel-Pro intake gaskets so I'm pretty sure the oil isn't getting in there. If anyone has any ideas (and a set of exhaust manifolds to fit a 390 in a 67-70 Mustang, don't want to fight with those damn headers again!) let me know!! Thanks!
