| Another SNAFU leads to learning |
| By John - 06/26/2001 6:28:24 PM; IP 24.222.71.214 |
Another screw-up. I have now ruined my second spare plug, but have learned something in the process. First of all, the spare plugs included with the Melling pump bought under Blue Wolverine P/N WG-324X (just a reg M57HV pump with extra plugs and an extra HP spring) were of a very soft metal and easily distorted despite my most careful efforts (and I am usually good at this sort of finickety thing). The original factory plug was a hard stainless steel and very well made ("true dimensions" vs roughly shaped). So what have I learned?
1/ Don't be a cheapo about these things...BUY a new pump!
2/ Certain procedures, however apparently simple, if done improperly with inferior parts could wind up failing and cost the engine dearly.
3/ That a HP version of this oil pump creates way too much oil pressure (approx 145 psi) before the relief valve starts to limit the pressure.
4/ That a blue-printed oil-pump offers insignificant advantages and is money unwisely spent (all I can see is the addition of lock-wired allen-head cover bolts and a bit of flaring around the output hole)
I still have a question...anyone got a P/N for the M57V pump with the 3/8 hex drive vs the 1/4? I think it was intended for the FT engines. A Blue Wolverine P/N would be fine as I can order by that # through the local machine shop. |
