Re: oil pressure problems from stock hardware
Thanks Smitty for starting this thread ! I'd like to add that the main oil passages can be drilled in the block as well as the intersecting oil passages , to give the mains more oil.
Also 3/4 groove H series bearings work well to provide a more continuous film of oil to the crank journals. Also a cross drilled crank provides better supply of oil. BBB |

I was told to watch my oil pressure gauges to make sure that the filter wasn't getting plugged. So far with normal oil changes, I haven't noticed any change in oil pressure. You can see from the picture it is a 20mm dia. freeze type plug driven in and staked in four places.
I did mine the same way. Good thread Smitty.It will help a lot of people!! |

Re: oil pressure problems from stock hardware
I am having trouble getting my oil temps up. I have bell housing coolers that seem to work too well. I can idle all day and the temp will not go above 140 degrees. At cruise it gets to about 180 degrees. I run cross overs with no water t-stat. Oil pressure runs about 70 PSI at cruise. Water pressure runs from 5 PSI at idle to about 18 PSI at cruise.
I have looked at several oil thermostats (PermaCool, Earls, Hardin, Merc, etc.). They range from $40 to $250 and all seem to do the same function. Any specific recommendations for marine use? Why? Thanks, Doug |
Re: oil pressure problems from stock hardware
I used Permacools last summer but they require a ton of hoses and fittings. This year I'm switching to Earls sandwich type http://store.summitracing.com/defaul...h.asp&x=26&y=9 They eliminate a couple of the hoses and makes for a neater installation.

Re: oil pressure problems from stock hardware
A lot of supercharger engines run wihout water thermostats to help control detonation. They work fine with the addition of an oil thermostat.

ttt Time to bring this back up.

Re: oil pressure problems from stock hardware
Anyone using the revolution marine oil cooler?
